Hopefully someone here can assist with my problem,
Megasquirt 1 on msns triggered from a hall sensor.
Initially everything was going well and i had the car running, ready to start tuning, or so i thought!
I have been having problems with the RPM signal sometimes being present and then disappearing completely. From around the same time i have noticed the fuel pump priming on and off. The change that i think i made which i believe to be the root cause was where i used easytherm in order to incorporate a pair of new, non GM sensors. Part of this procedure involved wiping MS unit and reflashing. My guess is that i have done something wrong in this procedure.
Initially i thought it was maybe the condition of my loom and the earthing etc. However i have gone through everything improving where i thought i could but have found no improvement.
My final attempt was to try reflash the unit which seemed to be working until the end where i had an error message stating that "voltage could not be aquired"
my battery was fully charged so this seemed strange.
Now i cannot communicate with the MS no matter what i try.
Any thoughts?
failed reflash (or maybe just failed!)

Re: failed reflash (or maybe just failed!)
i tried the reflash with the jumper in place, this time, it works!!
