Evening, have got a 2011 SV chassis 7, had a 1400 engine in previous, have rebuilt a 1800 VVC, got parts from Dave Andrews, has got a port and polished head, offset dowels and different exhaust cam. VVC timing and other timing is all on the marks.
wiring has been changed for the vvc engine instead of the 1400 mpi loom so now has vvc oil temp, actuators and cam sensor etc wired in.
ecu is a k maps ecu for the 1800, told them what I had done to it so they sent out a ready to go ecu. Problem is She starts half a turn from cold and idles at 1100rpm fine, Revs up ok and idles ok unstick she is warm. Soon as she warms up has a very erratic idle and cuts out.
won't restart without accelerator been pressed. Have tried the 5 pedal reset. Swapped the stepper motor and throttle body from my old engine that's done 14000 miles so know it's not these.
have spoke with k maps it's booked in week on Friday they suggested unplugging lamba sensor and didn't change anything. No obvious vacuum leaks etc. Any ideas what it could be? I'm leading to think it's ECU related. Moved timing tooth each way and it's noticeably worse so very confident timing is 100%.
just wondering if anyone has had similar problem before I take it to K maps for a plug in?
