Megasquirt No-Sync issues

Post by chittychittybangbang » Mon Jun 27, 2016 11:07 am

Anyone around Boston running a DIYPNP or MSPNP on a 96/97 manual NA miata?

I recently had some ECU issues and after repairing what I believed to be the problem (5V Vref / Opto circuit), am getting some "no sync" issues with my megasquirt. +/- 20-30 no-syncs over a 10 minute span.

I will much appreciate if I can meet you, and plug a known working PNP unit and start my car to see if the no-sync is in my ECU, or is a result of some other condition (like bad CAS).

If anyone has an extra CAS that I can test, that'll be helpful too. It is a hall magnetic type, on the exhaust cam.

I am happy to compensate for time, supply a case of beer, or help wrench on something in return.
