Ok so my car has been running fine for a while. Today I went to start it and it dident even catch.

It seems then when I crank it over, megatune shows a random rpm for .5 of a sec, then it shows 0 rpm.

For example, When I crank the car over, megatune will show 330 rpm and a PW of 3.2 for half of a seconded, then it shows 0 rpm and the resulting 0 PW.

Also, I have COPS.

I know the wireing from the bord to the harness is fine, I checked.

Its weird its like MS senses the RPM for a half a sec, then doesent.

What the hell is going on!? and I need the car to drive to the beach tommorow haha.... ****.

Is there something I can check with the cops?


ALSO IT RUNS FINE WITH THE STOCK ECU AND AFM (altho rich from my large injectors, but it runs none the less)

 

Could this be a software issue?

 

Generic Answer:

First: Try unpluging and repluging in MS and see what happens

Second: Reflash Firmware and load a KNOWN GOOD TUNE (N O T the one you're running right now).

 

Well I got it running... for some reason one of the wired imbedded into the MS bord was scratched and broken. I put some solder on it, seems to work.

But now the Tach in the car doesent move? lol this I do not understand. The tach gets its signal from the gray sheilded wire from the MS, correct?

 

forget that.

 

**** now its acting up again. **** it im re doing the whole wireing tommorow.

 

Took me like 3 hrs, but now the MS runs perfect. Yay for a shitty wireing job the first time around. haha

 

Hasn't you MS not worked like 10 times and "shitty wiring" was the culprit? Do I see a trend?

 

Its worked good for the past like 2 months... but the last problem was a wire mix up, this what shitty wireing. Oh well im done for good now
