Just installed this ecu a couple weeks ago and have been tuning with no issues.

Was on hill tuning accel enrichment making small changes. Car would stall from time to time and I would start it right back up, no problem.

This time...car stalled unexpectedly. Tunerstudio also went offline. Car turned over but would not restart....ok I say...battery must be getting low voltage...I take car down the hill in front of my house to jump it. Car doesn't respond to anything. RPm gauge is not moving and car is not responding to throttle inputs. Get to bottom of hill and walk a mile back up to get my truck and the stock MSM ecu. Plug booster cables in and make a few checks throughout the car and connections....car won't start on ms.

Plug stock ecu in and car started right up and came to life. Limped it home. Plugged ms back in. Won't respond..turns over as if ECU isn't connected at all and tunerstudio stays offline.

I shot Rev an email already....ideas anyone...it's not sounding pretty to me.

 

More details. The fuel pump runs constant when connected now.


MSPNP-fuel pump runs, does not turn off
Stock-fuel pump primes for a second
Disconnected-no fuel pump running at all

 

After a few emails back and forth to reverant...firmware was was "very" corrupted and via a process of opening case, setting a couple jumpers and reloading firmware. I'm back up and running.

 

with no issues?

 

everything is connected perfectly now and even saved the last tune on the ECU.

I can continue tuning now....or whatever it is I'm doing.
