5485, Help! MS3X isnt starting?
Posted by Gruff511, Dec-31-69 06:00 PM
Ive been going over all MS documentations trying to get it working. Last night it started but wouldnt idle without pressing and holding the throttle. Ive been messing with it all day trying all different combinations of steps to idle.
Would somebody take a look at my Msq and tell me if i have something wrong? heres the msq and datalog...

So i wasnt getting spark before But now i am. It still doesnt start unless i give it some throttle around 3%. Would this need to be fixed in the cranking pulse? or ASE? Ive been thinking its the IAC stepper that isnt opening enough(im still tryna figure out how to tune the idle)
Any info or advice would be greatly appreciated =)

Okay my problem was due to a faulty IAC valve. i got a new one and it will start now but im having a hard time making it run a little richer because im getting an oscillating idle with afr's between 14-20!
