Hello everyone. I am a bit perplexed with my input results. I am running a MicroSquirt unit(Black Board) version V2 with 2.89 code. I was originally using it for both Ignition and Injection
but because of the configuration of the motor, a V2-45degree with no tooth wheel, I found it simpler to use the MicroSquirt for injection only. The motor at this point starts remarkably well but as it runs the RPM signal disappears. It almost seems to be RPM sensitive but I am not sure of that. I have put a scope on the tech out signal line from the ignition module that I had purchased and it showed no missing pulses or pulses dropping out. I had Pin# 30 connected to that line and 31 to ground. I also reversed the wires Pin# 30 to +12 and 31 to the signal line from the ignition module and I also made a connection to the spark coil as recommended in MicroSquirt docs Coil to Pin# 30 and +12V to 31. All of these connections started the bike but had the same dropped RPM result. At 1 point in earlier installations I had tried to use the MicroSquirt's ignition and had set a bunch of parameters. Is it possible that those parameters may be messing up my RPM signal that microSquirt needs to run the injectors. SO I am looking for recommendations on what to do or look for. Or better yet, Is there any way to just disable the ignition side of the MicroSquirt. I have also sent with this post a copy of the last data recording I had done today. A pic is worth a thousand words. Any kind of response would be greatly appreciated. Thanks

I am a little confused here, nothing new

If I understand correctly, by using a tach input off your existing coils, and just replacing the carbs say with injectors for example, you don't have any ignition control, other than the existing ignitor circuit of the original system.

If you try to use the sensors that the bike needs to trigger the existing ignitor box, and couple these into the MicroSquirt, you have a combined ignition and fuel system, but you must set the parameters for the tooth triggers correctly, otherwise the MicroSquirt code doesn't relate to the engine position, and the exercise is futile.
