Lesson learned. ALWAYS REREAD AND DO THE MATH. I dug deeper in the manuals and was wondering just what the burn time of the gasses in the cylinder were doing. Surprisingly, if 17 degrees ATDC is optimal peak pressure then for my engine at a bore size of 2.95in. with the plug located offset 2in. to ...

I dug around in the manuals some more and found a section on trigger offset with some more info and an example. It showed that to change the timing by 2 degrees it took 10 degrees of offset. So I tried using bigger numbers and found that timing is moving as I change the offset. I'm still having ...

When I assembled the board I used the setup to control two LS1 coils using wasted spark per cylinder. Both coils fire at the same time every rev.. If that is any useful info..

Hello, I am trying to get my trigger offset set but no matter what way I move from zero it doesn't change a thing. My mag pickup is set right at about 5 degrees BTDC. Sitting there running at idle its firing at 0 to 1 degrees BTDC, but I can not get the 8 to 10 that the computer is wanting no mater ...

Thanks for the input mxrob. From what I have read what you are saying is what I got out of it to. I was thinking that the only reason behind that was because most triggers are setup right at or very close to tdc and ignition occurs before the trigger is ever seen. But if you have the trigger set ...

I did some rechecking and my question was on the right track. The computer has to predict when the next tdc will occur. I guess more specificly my question is will the timing be more accurate if the trigger is offset just before maximum ignition advance. I am running two the ls1 coils with turbo ...

I am working on my pickup for crank position and have some questions. The engine is a 2 cylinder motorcycle engine and I have removed the old stator and mag pickup and machined a new hub for the crank shaft. I am using a mag timing sensor with one magnet on the hub. I have read that if you use one ...
