ms2 diypnp no rpm signal
 
4 Attachment(s)
Well to make a long story short I ended up ditching my old ms1 v3.0 for an ms2 diypnp. I ran across a strange issue while assembling my diypnp for a 1990 miata. After assembly the board connected two the car and everything worked except I noticed that I was not getting an rpm signal. I did get an rpm signal with my ms1 v3.0 so I do not think the cas is the problem. In the process of trouble shooting my diypnp, I desoldered and resoldered r30 and removed and reinstalled the microsquirt cpu. After doing all this, the board would no longer connect and the fuel pump stays on all the time. I cannot figure out what is going on. I checked all my solder joints and resoldered anything questionable. The fuel pump is not jumpered to ground in the diagnostics box . Ive attached pictures of the board.

Fixed the fuel pump issue by resoldering the transistor from the top of the board.

I do not have spark or injection pulse on any of the cylinders...please help. Could this be an issue with the Microsquirt module?

Just checked and I do have power to pin1b on the main board

Please post a composite log of an attempted start and a copy of your MSQ.

I was not able to post a log before I lost connection. I'm currently working to resolve this over at the msextra forums. I will keep you posted on what happens.
