but if it put more of a smile................

But it can put a BIGGER smile on your face :p

Wasnt it only a matter of time?

If you look back in time there was many ZS 180 owners claiming 200 bhp with very little mods etc ie Back box.Decat and Induction.

Janspeed in Co-Hoots with MG Sport & Racing delved into this with the ZR 160 and the ZS180 and never got over a 20bhp increase with either car.

I am sure the said companies know what they are talking about.

MG S&R built some amazing cars and i am sure they knew there stuff.

Spose if the customers happy thats all that matters but you cant possibly think a multi million pound massively successfull company like superchips who's whole business has been engine re mapping for donkeys years couldnt find top end bhp , yet a small independant garage could.
I had my car worked on by superchips as did Ed and they have access to everything to change any parameter they please yet top end gains were nill to negligible.I remember Ed going to superchips hq at buckingham, and spending a small fortune on live mapping after he had a cat back exhaust fitted and after it all it gained just 1 bhp top end.
If you want some serious bang for your buck slap a small shot of nos on your car, even a small 25 shot will out perform 10 re maps.

Personally i have been looking into these "cheap" remap options a little, here are my thoughts


1. cheap off the shelf remap/chip jobs are always crap, slightly uprated generic maps might gain a little, but should be avoided.

2. a proper remap needs to be setup to each engine, to do this you need to be monitoring fuel and det.

3. i have seen a few posts from people saying that the remaps they do, don't touch the ignition advance, WHY????? this is mental, this is FREE POWER being left on the table.

4. the superchips name, i will never trust, after hearing about the superchips "chip package" that was available to early impreza owners, which amounted to a FCD (fuel cut defender) and a bleed valve ??? WTF?

Personally i suspect they (these "mappers" are not touching the ignition advance because they are scared/not knowledgeable enough to prevent the blowing up of an engine, due to crap det/knock control, preferring to leave the stock ignition map in place and try and optimise the fueling instead to give a small gain.

I mapped my last car myself using an Apexi PFC ECU, and did a jolly good job, so i understand how and why remaps can have benefits, adding ignition advance, and using a higher ron fuel can give you free power and torque.

When somebody pays for a remap on these cars and then can still use 95 ron fuel, that to me is just a big fat waste of time.

When i did my first Subaru Map i took things very conservative, basically setup the fuel map first, making sure it was hitting the right AFR`s across the rev range, after this i started adding ignition advance, in small amounts, constantly tweaking and logging to make sure it was safe, until i managed to get approx 9-10 degrees more advance while on boost, granted this is not the same type of engine and turbos give better gains, but it netted me around 30bhp and around 45lbft LOL this is comparing my rolling road runs from before adding the timing on my "fueling correct base map" to my "fueling correct ignition added" final map, it helps that my mate owns his own rolling road ;)

This was mapped right to the extreme of 99ron fuel, i could not use 95 ron anymore, and could only use 97 ron on light throttle, i was actually considering adding some meths to the fuel to allow a few more degrees advance but stopped the project as it was getting toooooooo insane to drive on the roads IMO


Now regards to the ZS180 and adding more advance, i suspect it can take a bit, after all its specced to make its max power on 95 ron, it may be that the silly design of the VIS system is preventing the engine from making more top end power, if people only seam to be getting mid range gains, then this could be why, to be honest, midrange gains will give better street performance anyway.

Somebody should make/design a simple replacement inlet manifold with no hocus pocus valves in it, and try mapping the car properly for it, i suspect you would get more top end gains.

Has anybody took a 180, fitted the exhaust/filters and then had it mapped for a proper higher ron fuel?

When i first went to see Matt the rollers down in yeovil were actually run by the main company performance3000, and my car on completely standard parts was about 6% up on torque and bhp... not really possible even for a 'good day'

However since Matt has taken over the remapping side and is the sole user of the rollers they do seem to be a lot mre accurate, backed up from a couple of different sources now..

For example a friend of mine has an old sirrocco which he has fitted a 20v corrado engine into, when we were there just a few weeks ago, Matt did a re-calibration for the file he had saved for the actual car.

I personally do not believe that Matt is the type to BS people with figures, and while i dont know whether he is touching the advance on the 180's, he sure as hell has been with the diesels.

the only problem we have had is that running upgraded (hybrid) turbo running over 22PSI with mild injectors fitted would cause head to lift... He has since worked out how to tweak things better and has taken the advance out again as he did not need it.

There a few diesel drivers who have had to get Matt's remaps turned down because they were too good and induced clutch slip! :)

Just cos a guy is an independant, does not mean that he does not know his stuff...

facts from 180 owners:-

1, i used him and im happy
2, mick has used him and hes happy
3, a few others have used him and they are all happy.

all of the cars in question have seen bhp increases all across the rev range and its definatally noticable on the road, my car is a lot better reving, its more happy to rev and this shows in the extra pull i have in the car.

so why is this in question???

So now you get the people saying he's fiddling graphs???? if your one of them then let me tell you something.... your a tosser.

it really pisses me off to see people's hard work slagged off. Matt has spent thousands and thousands of pounds on the latest equipment and technology and getting a reputation for him self, only for people to put that down on a forum.... that has many happy users of him

sorry to the guys that this doesnt apply to. rant over

In my original thread I discussed what went on and why. I could have gained more if I had chosen a higher grade of fuel, like V-Power or BP Ultimate but personally chose the lower 95RON purely on cost. Considering I do around 350 miles a week commuting, the extra cost would have been unjustifiable if using 97/98RON. Yes it would be nice to have the extra horses but I am not that desperate for them.

Matt has spent alot of time and effort on his remaps and has many satisified customers, especially on the K-series and diesel engines. However as mentioned before he did very little on KV6 as no-one was willing to offer one to try, not surprising as most KV6 owners are indeed sceptical about chipping and remapping. I can also be included here I might add! I do believe after a days running on the dyno and studying the standard map that Matt has interrogated that he knows where to tweak them and where to leave them alone.

I can only take my hat off to the man for attempting to take this on and really understand the KV6 and work with it until such time gains were made. Okay the gains that were seen were not as we both had hoped but at least there were improvements from the original figures and that was the point of the exercise.

Sometimes you can be working too closely on something and fail to spot the obvious or be blinkered by opinion or by not thinking outside of the box. With Matt he applied his knowledge and with a fresh attitude looked at the whole application from a different perspective.

I know opinions will vary as that is the nature of the business, we all have choices and will always be sceptical about claims. As a personal choice I am more than happy with the results and that is not just reading a piece of paper or reading a screen. I have been involved with motorsport for many years and never take much notice of what figures are produced and only measure the improvements, if any, when on the road as that is where the differences are measured. I have used many rolling roads down the years and yes they do vary as there is very little done to police the calibration. The only way to gauge improvements is to use the same set up everytime and use this for comparative results. I did this many times when trying to solve the fueling issues on my old Audi GT supersaloon, took several weeks and runs to iron this out and during this time logged the readings.

I think I have gone on long enough. Obviously the jury is still out and will be for sometime. I'm more than happy so will leave it there.

Its easy enough for anybody to "fudge" a rolling road result if they know what they are doing, hell, even pumping up the tyres for a second run will give different results!

People should never get hung up on figures to an extent, the main use for a rolling road IMO is to judge your mods, travelling from different rolling roads and getting different figures means nothing, its better to pick one, and use that one over and over again, to see if your mods are having an effect.

The Subaru and Evo lads are generally numpties in this respect, preferring to go to "Place X" because they will get a better result over "Place Y" a completely ridicules practise, me personally, i would prefer to go to the one that's known for offering lower figures, as the chances are, you are probably getting real results and not fudged results where the rolling road operator held the handbrake on a little bit, or never fully backed off the throttle for the coast down to affect the calculations ;)

Nothing wrong with remapping a car IMO, but a simple "fuel map optimisation" is never going to give what i would consider "good" results, unless the map currently in the car is not giving good AFR`s for the current mods/engine spec

Diesel remapping/tuning is a slighty different kettle of fish :D i had an old vectra derv that used to run 1.35bar boost, that was pretty nippy, although i was using about 1 head gasket per year LOL :D and killed a head, plus a turbo :D

Have you thought about the possible increased MPG benefits, having a more efficient engine running a higher ron fuel ?

if you can increase the ignition advance safely at say 3krpm, without adding in extra fuel to help cool the cylinders, then you will gain power/torque and MPG.

its a win win situation.

the last place i went to, and peterzs will back me up on this as he went with me often have civic type r's there. he said all the type r's they get in only run at around 180 bhp and never above 185 bhp on his rollers. even though honda claim they are 197 bhp when they leave the factory. my zs that mg claimed was 177 bhp ran what it was susposed to run, so whats up with these honda's??

Hi guys its Matt here,

I have been reading this thread and i can see that there are some people doubting my work. All i can say is feel free to come down and put your car on my dyno and il dyno it and map it in front of you you can see me sorting the airfuel ratios out and watch the power go up.

I have seen maps done by other companies and it seems most companies dont understand this ecu so its no suprise if they dont get good gains. most just increase the timing and say thats it all done.

But you can control the vis and you can get power from sorting the fueling add this together with a bit of timing and your looking at soome good power.

one thing i will say is that no car has been the same on the dyno the plenum and vis plays a big part in the torque and power delivered and it being setup slightly wrong will give odd torque figures.

Feel free to ask away.

Cheers guys Matt

I assume these remaps are done with a new ecu installed?

as i was always told the standard MG ecu is unmappable :oldtimer:

No with the stock ecu and the ecu is very mappable. and through the obd port as well which most people will tell you isnt possible.

You just need the right kit.

:wizard:

:hi: aboard Matt, glad to see you here and answering questions which is what we need.

:thankyou:

Hey Matt,

I'll be giving you a shout in a few weeks time hopefully :) - Time for a reeeeemaaap :D

as matt said all work is done in front of you, my fueling was all over the place and timing wasnt great. matt soon sorted this out, and mapped the car from that point. although i didnt make as much power as mick, as my plenum has issues i still noticed a difference and im very happy with the result.

people spend £400 for an exhaust system that will give you 5bhp but are reluctant to spend £200 on a remap that can give 10-12 bhp. my question is why??

Why has it took you so long to do this?

When can we see one of your mapped cars at Santa pod or on a trackday etc to see if your mapping actually works?

The only way you will gain any trust is by real time recording etc

I'd deffo be up for a santa pod day!

I disagree, he has mapped several KV6's now, every owner has reported an improvment in mid range which is where it really counts.

The only "garage" who seems to specialise in ZS's seems to find faults that the drivers didn't know they had.

Until customers start to report that their Reidy remap hasn't made a difference I will believe that it has.

I dont understand what you mean by why has it tok me so long to do this?

I will be at santa pad from the 31st of july for ultimate street car and will bring my mapping kit along although mapping the zs 180 for max power can't be done unless on a dyno anyone who says it can is just looking to make money not provide a service.

Although there is a dyno at santa pod for this event.

At the end of the day i dont hide anything you can see every map being changed by me sat next to the car on the dyno then watch me load it into the car and do another power run, the cars are never done first time and sometimes it takes up to 15 times for me to be happy I cant get anymore.

Cheers Matt

Matt when funds allow I will be heading your way I've heard enough to make my mind up and to be fair the extra power will be nice but my main reason would be to get the fueling right as I understand this can be thrown out with mods!

Brett

No problem my contact details are all on my website so just give me a call or txt when you are ready.

Cheers Matt

I keep meaning to hook up my LC-1 wideband and do a few logging runs to see how my cars fuelling is doing, but always forget all about it when i am back at work :D

I am wondering what the results would be if somebody butchered an inlet, removed all the VIS crap and then redid the map from scratch as a proper non VIS map.

I downloaded the demo for WINols although you seam to be limited with it as you cant actually use it without the OBD2 lead, which i have still not bought lol

Matt was intending to do this but would require a car for a couple of weeks. They do have a Rover 75 KV6 but the engine was found to be duff.

If you wish to remove all of the vis system why not use an 800 manifold? Not sure what ecu the 800 uses but it can't be far off the same specification you are describing.

As for new plenums I am waiting on the results of Lunar Racing's R&D one, but there is no project plan for that, so no kowing when this will be, if ever.

or buy word of a 180 owwner that has noticed a difference, why cant people take other people's word. there are 3 or 4 people on here that have had the remap done and all have noticed a difference. isnt that good enough??

You'll never be able to please everyone, there will always be sceptics regarding certain areas of the KV6. I too was sucked into this train of thought until I snapped out of it and decided to find out for myself. I soon found out that there was no evidence to back up the claims that it was fruitless in search of remapping.

As the old saying goes 'the proof of the pudding is in the eating'.

You simply can't please everyone, and some will try to find out every single morsle detail for...no reason what so ever. Just to try and catch the mapper out. At the end of the day the results are proven and theres no real solid reason not too do it. It's not asif it's another supercharger scenario is it :)

When I spoke to Matt regarding using my car as the test bed I did so knowing full well the opinions of owners and tuners alike.

We both went into this session with an open mind and seeing what was available within the standard map and then interrogating it in order to tweak where possible without compromising the quality. The bottom line here is if the session proved to be unsuccessful I would not be charged for the days work. Obviously as an engineer I was watching the work in progress and getting an understanding on what was being done and the cause and effect.

If I had any doubts about Matt's work I would not have gone through with it, but why would I doubt a fellow professional? He has had alot of success on other remaps therefore had the upmost respect for his work. It's a pity some people doubt this just because he has succeeded. Sometimes a fresh pair of eyes and mind is all that is required, sometimes you can be too close to something to see it.

If I had a 180, I'd take it to Matt. Respected forum members have had good results backed up with evidence... if George and whoever else couldn't do it, well the evidence is on paper, so they just can't do what Reidy does... simple.

Also with the demo you cant export a file so you cant make one and put it in your car you need the full version. :)

On another note I did 2 TF remaps today and dyno'd 2 others which had been remapped by superchips and one other comapny who I wont mention as the may frequent this forum.

Both cars I dyno'd made less than stock power and both were over fueling a lot in the top ranges especially.

The two cars I remapped made a good 10 and 12bhp respectively and also had a good fueling ratio of between 12.5:1 and 12.9:1 compared to 9.2:1 of the other companies remaps. some comapines think that by adding fuel you get more power this isnt true in most cases and this is also another reason generic tunes shouldnt be used as the superchips map may have worked on the car they did it on but every car is different and so is the enviroment so its no good tuning a car in germany and saying this file will work on all.

The customers were happy and the two cars that were tuned by the other companies are now coming back to have there cars properly tuned so they arent over fueling and they can make some decent power.

The graphs will all be avaliable on the .org forum soon as they wanted to post them up so feel free to look in the TF section and see what other customers have to say about my work.

Matt please ignore the nay Sayers, you will always get people who want to question everything and just aren't satisfied. I know full well you'll be getting my car when I can afford the map :)

What's done it for me is that everyone who's been down to you, has come away happy. Now if there are issues with your rollers and the figures ... I'm not that bothered.....the people themselves, (well respected and highly thought of), have testified to the fact that their car just drives better, and that, my friend, is all we're after.

Whatever I get .... be it a 180 , a diesel, or non-MG .... I'm coming to you. :thumbsup:

i went to him all the way from the isle of wight and i was well pleased.

Indeed you did Ric, did you get that HID issue sorted?

reidy, this is off topic but i mentioned you to my friend, he has a 2003 astra gsi turbo, its completly standard at 197 bhp, what can one of your remaps get this up to?? how much do you charge to do one of these?? hes been considering the phase 1 from regal autosport, that are just up the road and they claim their software will take a standard z20let to around 235bhp.

sent the faulty ballast back this morning. they will send me a replacement :mml:
