Howdy all,
We have finished our car and are ready to do some serious testing. We have had a small problem with the engine running, it runs very rough and stumbles.

We have a megasquirt MS3Pro from Wayne @ Very Cool Parts since it is an 818R and will not need anything more than that.

We can pull the injector wiring and/or coilpack wiring for cylinders 2 & 3 and it has no effect on the engine running. We have swapped in new injectors, new coilpacks, etc. but still no change. We had replaced the timing belt when the engine was out. Our local engine builder said it is easy for it to jump a tooth when reinstalling so we pulled the cover off today and reinstalled it - but it turned out to be right on the marks to begin with.

We have checked the wiring and it seems to be fine, is there any way to verify the megasquirt is sending the proper signal to the coilpacks/injectors?

Any ideas?
