So I have my 3800 series III running and driving on my MS3 with the MS3X wired for full sequential. I am currently running batch fire ( 2 squirt per rev alternating) my question to anyone out there is Tooth #1 angle.
This is what I need to know to get the timing right for full sequential . Now I know the trigger offset is 75* , trigger of set is used in basic trigger setup I need to use toothed wheel mode for full sequential . The C3I module low resolution out is 3 pulse per engine cycle . With that said each pulse is 120* and represents TDC of the pair of cylinders I.E 1-4 , 2-5 and 3-6 . The last bit of info I know is the cam pickup on the rising edge is almost exactly TDC of 1-4 .
If anyone out there thinks they have some info that could help my please share , I am open to trying about anything at this point .
I will get some pics of the car and setup in a awhile here , maybe a video as I am running Chris's NSX tranny setup and so far I really like the gearing.
thanks

ok here is another question , I know the C3I module has a base timing of 10* for start up and limp mode. Is that 10* always accounted for in the GM tables ? or once the PCM takes control via ignition bypass signal then the advance tables in the PCM are total advance numbers ?
In simpler terms , is there always 10* from the C3I module ?
