Hi All,
2jz non vvti NA-T
I thought I will open a thread in case someone had a similar issue.. as after months of looking still no luck.
Below I have attached a graph from EcuMaster log. 2nd gear looks pretty clean, but once I change to 3rd it start to misfire straight away, 2nd and 3rd gear both in same boost 175kpa mark.
I dont get any misfire below 10psi of boost.
Parts I have changed:
Injectors - 715cc bosch ev14
Coilpacks - yaris smart coils
Fuel Pump - walbro 450lph + Relay mod
Spark Plugs - bkr7eix and bkr8eix
Fuel Dampener Removed
BC valve springs and bsc stem seals
On high boost ECU and engine is not loosing any voltage or fuel pressure. Compression on all 6 cylinders is good.
Things like changing dwell time, gapping spark plugs, changing map and etc have been tried.
It kind a feels like it is more mechanical than electrical issue, engine get higher load in 3rd gear and starts to misfire? but what could cause that
Any suggestions welcome!
Thanks,
Ed
