Car is GMC sierra 2009 with LS3 stroked engine and TVS 2300 methanol and c16
it seems that the car is not following the spark tables while i'm commanding 25 degrees it seems it just take 13
there is no KR also i disabled all multipliers just to know what table responsible for this issue but without luck
if some body look in my log and my file

thanks in advance

You will probably have to make up some pid list to log a lot of the spark pids to see what is actually altering your spark. There are quite a few DMA pids in the spark section that may help you out also the octane scaler.

There is no set list, log as many as you can without slowing down your logging speed,you may have to make up two or three pid lists to achieve this,also remember to include same of the basic pids like rpm,airflow, iat etc.
