Hi all,
After few hit and missed, finally got my car tune today. Everything gone so well, achieving a good target 26 PSI - 390HP.
Everything was good after the last power run complete with road test.
But things turn bad after taking some pictures, the idle start to rev up (idle surge?)
It just happened randomly. I have an AEM wideband AFR which shows it is running lean but when we put the foot down the AFR shows the value again.
Plug back the standard ecu and everything works like the old time, so we think it's the software problem.
Car has the Link 4 Bar MAP Sensor too.
Any thoughts of how to solve the idle problem?
Tuner going to call Link for advice tomorrow.
Thanks

Thanks Simon. Question, but when we plug back the standard ecu everything is back to normal. Â Would it normally show the same symptom on standard ecu?
