Can't get my RPM to sync MSPNP2 Exocet build
I've been searching everywhere for a solution to my issue and I've tried several "fixes" but I'm just out of ideas and apparently knowledge.
I've got a 1999 engine and a second hand MSPNP2 (I know, first mistake) and am just getting my feet wet in the whole standalone ECU and tuning world.
I have everything hooked up as it should be, I think, with an Innovate MTX-L and the GM IAT sensor. No turbo yet. Everything seems to be working fine except that I'm not getting any spark and I'm getting the "not RPM synced" red button illuminated.
The OEM ECU works fine which tells me my crank sensor is set correctly and the car runs perfect with the OEM ECU.
I've downloaded the most recent firmware and followed several videos on setting up the base map for the '99. I've tried several different settings based on some forum recommendations but they make no difference. I'm concerned at this point that my MS2PNP is suspect. Since I didn't build this one I really don't know where to begin on troubleshooting the damn thing, so here I am.
Pics below of the MS2PNP innards and I've included my tune files if anyone is interested in helping.
I'm so close with my turbo build and I'm in the final stretch but this one has me stumped.

It seems like everyone who has had this issue downloads an updated firmware and then they stop posting. I’m assuming the firmware fixed their issue. I downloaded the Microsquirt firmware. Is there another firmware version I should be using instead?
I’m afraid to just start swapping firmware because I read that using the wrong firmware can fry your ignition.
Can anyone point me in the right direction on which firmware I should be using for my build version?
Thanks

I've only built a MS3. I don't really have any experience with MS2. I believe MS2 does not support alternator control which means you'll have issues with a NB alternator
Edit: To clarify, I believe the lack of alternator control applies to a DIYPNP. Which is what you have. A MS2PNP has a separate circuit for alternator control. That's why I'm a bit suspicious of this ecu being built for a 99 chassis.
