Default Ms1 v3.57 has no tach imput,ms shows that there is no rpm but all other sensors work
Ms1 v3.57 I'm running parallel to the stock ecu.ms has no control right now,just getting the inputs wired and it never shows rpm. All others clt, iat,map, work. The wire has good connection ,don't know if there Is some thing wrong with the ms. I bought it off eBay. And the rpm input doesnt work with jimstim.

How did you build the RPM input circuit? Could you post a copy of the MSQ?
