Update....
Slightly disappointing result on the rollers today (the day was good though, well done all who attended)....
Last time I was on the rollers I got 383bhp and that (as it turns out) was with a split vacuum pipe to the FPR which gave a boost leak and reduced the FPRs ability to control fuel properly (which is why the duty cycle on my 630cc injectors was nearly maxxed) and a std exhaust which was affecting the EGT's and stifling the engine at high RPM.
I fixed the pipe and the mapping (predictably) was overfuelling so reverted back to a previous known good one which I have been running since as Bill has had far too much on to sort it properly and I wanted to get the exhaust on before I sorted the mapping out.
As I don't thrash my car within an inch of its life, the map has seemed ok and I haven't done any logging since it was put on. Did some logging today and it seems leaner before boost and then just goes bonkers and dumps fuel from around 5.5k...
Needless to say its back to the drawing board and I will do some more logging to see what's having an effect on the fuelling. I thought it was EGT's initially but using my Liguid gauge on the way home I couldn't get EGT's over 960 degrees... Thinking I will log EGT's vs Fuelling and see if there is any correlation to rule it out, the alternative is to move the EGT probe as it may not be in the right place where it is now.
