So I don't believe it's just a tune issue although it's possible that Cosworth did not compensate for it. Maybe it can still be tuned out.
I wonder if @ Matt@Cosworth has noticed this on any other Cosworth vehicles. Is the problem in ECU tuning or is it a mechanical issue? Maybe the little 2.0 is just not strong enough to quickly compensate for the A/C compressor cycling. |
the idle speed on these cars can be a bit erratic
on the stage 1 tune all the stock idle speed control was carried across so its the same as the standard car in this respect and I've found it will improve after flashing once its done about 200 miles as it applies the learned settings
