Problem with spark

Post by happythoughts47 »

I have a ver. 2.2 MS with the mods to run spark in a neon, and using a external mitsu ignitor.
The car was running good on msns-e ver. 24s9. I then deceided to run 29q2 and the newest Megatune. I reflashed the firmware. I then forgot to set the spark to non-invertered. I tried starting the car. I then noticed the mistake and changed it. After this I can only get the car to run off 2 cyclinders.
The middle led on the MS blinks when I crank the car. The other 2 (17,19) stay on solid while cranking or blink so fast it pretty much looks solid.

What could be the problem? I tried using my old hei4 ignitors and the car still only started on the same to cyclinders. It seems like the outputs on the MS is dead. What should I look for? Any idea's?

Bump
Anybody have any idea's what could be the problem? Or what to test?
How would I find out if the MS outputs are working properly?

Try loading back your old firmware, settings and Megatune etc.

That will at least confirm if it is configuration or hardware.

check to see if you're getting spark.. i blew a fuse to one of my injector banks due to my pwm settings getting reset when i updated firmware.

also, what is the 3rd led configured to display?

I tried the old firmware and software. No luck.
I have led 17 is spark, 18 is trigger return, 19 is spark output b

I tried a new j-yard ignitor and that one was burnt. I got no spark at all. Went back to my other ignitor and it started wiring on 2 cyclinders again.

I tried switching x11 and the coil wire to the other side of the ignitor, to test both sides of the ignitor and it won't work. I also tried using the x12 output to the 1 known good side of the ignitor, also no spark.

There is 4 ways to hook it up to test spark, and only one way produces spark. So to me it looks like there is half the ignitor that is bad, and 1 MS output.

What should I look at first? What is most likely burnt? Nothing looks burnt and the leds light up.
