71553, Nitrous w/ ignition timing advance and valve timing advance
Posted by E-CLIPS97, Mar-27-04 05:18 AM
I have tried to find a difinitive answer to this question but have yet to find one. What precautions would I need to take in order to have a af/x ecu(adjusts ignition timing), cams and cam gears(adjusts valve timing), and say a 35 or 50 shot of nitrous? If you provide any info on additional parts needed to make it work like Msd ignition or something please provide part #'s if possible.:cheers

slightly retard the ignition for the 50 shot.
you could get away with a 30 shot without changing it.

Im pretty sure you dont need to do anything. It has been said that the afx ecu will work with nitrous shots under 75. I also think if you retard the timming then you are defeating the purpose of the afx ecu.

Well i read somewhere that one of the msd or crane ignition systems allows you to have advanced timing, and the once you arm the nitrous it automatically retards the timing, and only keeps it retarded until the nitrous is unarmed?:shrug
