ok so at least its picking up the signal do you know if you have j 10 jumpered to igout on your board and any way to send me your setting from megatune maybe its just a incorrect setting . Zane

i got its sparking.the problem was the q16 was shorted to heat synch.i read that one version on the driver had a live tab.so i raised it off of the sync and its sparked.it will run but it acts like the timing is off.i read on the msd page there are setting that i nee to adjust.im going to do that tonight.if ther any othe settings i need to change let me know.thanks
