Hi, having trigger errors on my car, engine is a 2jz using 36-2 crank wheel and 1 tooth cam sync
Was running fine last season, over winter I changed to a built non vvti head using cam sensor picking up from Exh cam gear, fitted dry sump setup along with some other small upgrades.
Car was running fine with no errors last seasons
Just to cover a few points, I have tried cam sync off and it still shows trigger errors. At one point with the engine running and cam sync off if I plugged in a cam sensor (not fitted to engine) It made the engine cut out then wouldn’t restart until I disconnected
The engine is a 2jz with standard crank vr sensor and a non vvti head so use a aftermarket cam pickup which uses another identical crank sensor to pick up from a adjustable cam gear bolt
Initially I thought it was a cam sensor fault causing trigger error but obviously isn’t as with cam sync off it still does it
The car has done approx 6 hours on the dyno with no issues at all, went to track and had this issue so changed crank sensor, ran on dyno for a couple of hours to confirm it was fixed and all good. Went to track yesterday and straight away had issues.
Sometimes it cuts out backfires and wont start until 10-20 mins (sometimes no signal on trigger scope when cranking but sometimes there is)
I have tested wiring which is all fine, tried 3 genuine sensors and checked the pickup wheel for teeth damage and all seems good.
The ecu has been on the car for approx. 4 years and running without fault, the only change to the car is the non vvti head and different cam sensor setup but like I say with cam sync off it still has the issue
Also iv had the loom out, double checked all the wiring, changed the ecu earth to its own post on the engine block , the coils ground separately to the cylinder head
Still the same, iv attached the tune and various scopes and log files. hope this helps
Thanks
