Big ignition advance at low load
Hello. I have a question. if there is the possibility of damage to the engine by a lot of ignition advance, but at small load?
The ign was 40-50* at 80kpa load max. Engine is stock ej20tt from legacy

80kpa is nearly atmospheric, timing should be about 30* here depending on compression ratio, afr, fuel type and engine speed.
i doubt you will damage anything but you will be loosing power.
20-50kpa can see 40-45* in certain load areas, what ecu are you using?

you're right. about 30* is on my ignition map. the problem is that I have diffrent crankshaft pulley and timing marks on it are in the wrong place. I adjust the trigger and strobe with timing light. But timing mark is not the TDC. Its 20* advance. the entire map is shifted by 20*. I wonder now whether knocking occurred and whether or not damaged engine
