Syvecs Forums

Hi Guys, i was just wandering what can be done about my engine Hunting intermittantly? It has only done this since the new Syvecs ECU was installed a couple of weeks ago, Pat installed the ECU at scoobyclinic and he said that my Syvecs ECU has the latest software which i'm sure he said there used to be idling problems with the early software, i'm going to send a message to Pat to see if anything can be done but would like to see if anyone else has had the same problems. My car is an 2000 Impreza P1, any advice would be helpful. Thanks

I'm running aftermarket cams and lightweight flywheel and the idling was a bit problematic for me with Apexi PFC.
The idle strategy of the Syvecs ECU is very well when compared to my old Apexi PowerFc. Especially the vehicle speed related idle control works like charm!


I am still having problem when the A/C is ON. Target idle needs to be altered when the A/C is on but I couldn't find a way to do it.
