My DIYPNP install! Options

[lagos]

I finally found some time to assemble my DIYPNP kit today. :thumbup
The assembly process wasn't too bad. Everything was clearly labeled and the instructions were easy to follow. But if youre reading this and you bought an MSPNP, consider yourself lucky as soldering lots of very tiny components too up most of the day (and I'm still not done!).

I started out with this:


And after a few hours here is where I'm at!



This is the kit I'm using.

Along with the sequential injection mod.

I take it that your board is getting 12V+ from your car and a good GND connection? Its difficult to troubleshoot when their isn't any wiring schematics at DIYautotune

Yup. My 12v and 5v pins all check out and it looks like microsquirt is getting power. I ran serial loop back tests through the pcb board, have continuity between the serial port pinouts and microsquirt and I'm getting power and ground at all the right pinouts from the serial port. Everything should work.

You're right, I didn't see any detailed schematics for the diypnp 1.5b pcb board like there are for ms2, ms3, and microsquirt. But from what I can tell, it looks like the serial port goes directly through the pcb board into the microsquirt module, so if I have continuity between the serial port and pcb, everything should work.

So all signs are point to it being an issue with the preassembled micrsquirt board. I'll be sending it back to diyautotune for testing and hopefully it ends up being a warranty replacement issue.
