No dodgy MIL eliminator, I just clear the light with an old scanner every so often but it's often got the light on for a while before I do. Ok the below five thing makes sense, thanks. I do feel a kick at just before 4k so that seems to correlate a little on the graph. |
question is, how happy is the ecu with that.
the ecu has adaption channels, have a think about the parameters the ecu sees and how it adapts to the sensor voltages it sees and adjusts for these as well as general engine wear. personally I'd fit a 100cpi cat minimum sort the vis if they aren't working (and they don't look like they are) and reset the adaption channels. I think you may be confusing that kick you feel just over 4k with the natural intake pulse length harmonics that happen, looking at the graph I'd say no working vis and its just pulse length your feeling. |
Cam timing is out. Piper don't put the keyways in the same place as std cams

What's the wheel power showing on the dyno? Wouldn't even bother looking at the corrected figures

That could well be a plan at some point, I'll have to see what the calendar is like lol! Sounds like an awesome bit of kit! I'm not so sure now on the mechanic! Thought he would be fine as a lot of people use them where I'm from but maybe he got it way wrong and it's out as a lot are saying and he's screwed it up! Quote:
If those are different does that mean to use the standard timing marks or not? I've never timed an engine before but is there any pictures or what should I be looking at to have a quick check. Quote:

interesting the point where hp and torque collide...
did you see the car rev out on the tacho? was the guy watching the dyno screen revs to rev out or your tacho? did the engine hit the rev limiter? |

most people time them up with the standard rover timing tools as so few people have exhaust side verniers. the rover timing tools way of timing does not produce a graph like that, but I think the comment above may have stumbled across something interesting |

It sounded like it hit the limiter each time to me, I didn't see the tach or the dyno screen tbh. Didn't know to keep a eye on it! Just watched a couple of the vids back and it does seem sound like it revs out :/ |
yup, should be 5252, so if you re-align the the rev graph to 5252 and if the engine was not revved out...
Just a theory, may be way off... https://c1.staticflickr.com/6/5539/2...113d44a0_b.jpgskillenrev by mark stone, on Flickr |

That's why I never use that garage heard many bad reports about them not being the best. |
