Quite busy with life business, I hope I can start this Jeep by this weekend. I see trigger pic :-

Trigger offset is 484, so it is a rough number or solid?

TdcPosition is trigger oen business. You should use trigger offset zero.

I am pretty sure these are fake or not exactly OEM quality, but could work good enough for our purposes

Working on this car again, I see most of its wiring got slighly burn mark (wire insulation melting everywhere). Currently I change trigger to 16-1 running at cam speed. Do Rusefi support this?

Not much fund I got from this car owner. I do the trigger wheel which is very low cost. So this should work?

I do not understand the picture above. Which part is the wheel? Where is the gap? Where is the sensor?
