INJ outputs not working on DIYPnP
I just built a DIYPnP for a 1.6 miata. Hopefully this is just an ID-10T error on my part, but I suspect that the microsquirt module is defective.
Two issues when running it on the JimStim:
1. The O2 sensor is reading 0.28 volts in megatune regardless of the output voltage from the jimstim.
2. Neither INJ output is working (INJ1, INJ2). Jimstim INJ LED's don't light up. Multimeter confirms 0v on both outputs.
All other functions work in TunerStudio... it's sync'd up and displays the RPM and PW... so the injectors should be firing. Jimstim is confirmed working with another megasquirt.
I built it per the 90-93 instructions. I only included the 5v circuit, high side driver, the 2 pullups (R3, R4), and the iac flyback diode (R5). It's wired per the spreadsheet.
I put 3.0.3t on there and loaded DIY's default config.
Any thoughts before I email DIY?
