URGENT Need help, no RPM input!
 

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.... fuck.

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.

fuck now its acting up again. Fuck 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 :)
