I can explain it,you can be off a couple knoches, with this engine,and it will run,,but when the ECM,take,s note of the wrong postion,it will try to correct it,and that,s when you have to go back and do it,this diagram will show you how this works,you will have to get timing on this engine right,there are diagram,s on google to show you the exact position it has to be,then the ecm will work in your favor.

So got the cam gear timed off the white dot to the make you showed in picture, balance shaft timed to exact mark, crank wouldn't line up to marks but got at TDC starts and ran for a few miles and now I'm back to it barly running. Could computer be bad or that part you sent the diagram of?
