I havn't grokked the wheel settings yet. SO I have a few questions. I ave a MS1 v3.0 board. CB Magnaspark trigger wheel with VR. AT TDC sensor is over 8th tooth. The missing tooth is at 115 degrees BTDC.

i don't know what i should be putting into tunerstudio, Nor what it means. What is trigger angle? it says to use 60 ???

I used the excel cheat sheet from msextra.com


using the excel i get these numbers.

I'm using MS2 but on my set up the trigger angle is the angle BTDC when the missing tooth aligns with the sensor so in your case it would be 115 degrees.

I'd say turn the fuel off and put a timing light on it and see where it's at then adjust from there.

So for a base timing @ TDC do I want it to fire at tooth 8 for cylinders 1 & 3, then again 180 degrees later at tooth 26 for 2 & 4.

I have it set to trigger A 2, return 7.

trigger B set to 21, and return 26.

Trigger angle of 70.


Should that be a good start ?
