HEI only triggers off of Duraspark ditributor if I spin fast

Post by mattscot007 »

MS II V3.0

I have a duraspark distributor and a 7 pin HEI module. I only get a tach signal in MS if I spin the distributor much quicker than the truck starter can turn the motor. I have this problem with the VR sensor directly connected to MS as well. I did the HEI changes to the hall circuit as described in megamanual.com/ms2/inputHEI.htm

I have no scope to see if the problem is the HEI not picking up the VR signal, or MS not picking up the HEI tach signal.

PLEASE HELP!!

I have been playing with the distributor turning it by hand out of the motor. After I turn the distributor only a small amount, the "READY" goes to not ready in MegaTune. Can Anyone explain this or does this shed any light on my problem? This same thing happened with the VR sensor hooked directly up to the MS using the V3 VR circuit.
