180 remap, where and worth it?

I say it is worth it, if anything it tidies up the power delivery when past the power valve opening and you will get an improvement in mpg and high end AFR is sorted as the the stock ecu map is a little flawed here.

Up to you at the end of the day as always mixed opinions on this. I wasn't disappointed and noticed a much better drive when I tracked it from its previous run when on stock map. Never timed it as not that into it just enjoying it for the driving pleasure. Still, it made the ZT260 boys ask what I was running.

Mines been done 3 years now and still pulls well and returns a decent mpg figure.

How does a remap affect the ecu making its own adjustments?

expect about a 25bhp. Got my remap done at Reidys, before was 173bhp and after was 198bhp (oe cams). This was at the height of summer and i didn't have a heat shiled for my induction kit (which in my car is located close to the radiator).

There must be a power gain, not that you can feel it that much as in a derv (dervs are more affected by a remap). It's true you've got a self-learning ECU, but as said, it just self adapts on breathing values, usually it takes 20 miles of driving to re-learn. All other modifications would require a remap in order to experience the full potential.

[stamford]

The Siemens ecu can only learn a small amount and doesn't have the ability to advance the timing, only to retard it. It can change the fuelling by a small amount to allow for changing weather conditions.

The remap can go beyond this and advance the timing and the AFR until such point you can't go beyond the parameters within the stock ecu.

And if you change the ecu, for instance to an emerald. Not that I can afford one.

Reidy's don't list any MG's on their site...?
