No spark when cranking
I an not getting any spark when cranking. When I use the spark output test mode i can get spark. I an not receiving a RPM signal when cranking and i think that might be the cause but I am not sure what to check now. The car is a 2004 Mazdaspeed miata and I'm using an MS3X. I followed the wiring instructions on turbokitty.com and I'm using the turbo kitty basemap and firmware 1.4.1. I have attached the .msq composite log and data log.
Thank You

I was able to work on the car and confirmed that the megasquirt is causing the issue. With the stock ecu installed and the keys out of the ignition there is a current of only 7mA. When I install the MS3 the current is a little over 3A with the keys removed. I also noticed that with the megasquirt plugged in and the keys removed some of the dash lights are lit very dimly. I found someone with a similar problem to me on post number 14 of this thread https://www.miataturbo.net/megasquir...f-94001/page2/ Their fix was to use an injector output or WLED for the main relay. I am currently using INJ G for the radiator fan can I switch that to Nitrous 1 and use INJ G for the main fan? Otherwise it looks like I can wire the WLED to pin 3 on the megasquirt but I am not sure how to do that. Any help is appreciated.
