NEGATIVE SPARK VS ENHANCED

Post by encrypted »

Trying to set the decel tables in a vs v6 enhanced bin when set to a negative valve and saved when you reopen the table it’s set to 0 instead of a say -15 on decel is there a max spark retard table somewhere you have to change to let it go into negative value in vx/vy I can set it to say -20 on the decel spark stables and it will stay at -20 and have stupid crackle on decel

Check the equasion in both the XDFs and see whats dfferent. It could be that the range is changed and now starts at zero so you can run more advance, or it could be just done with a different equation or setting (signed vs unsigned) that you can change to get it working. Im not saying it does work, just where to look.
