MSII just went down - any suggestions?

[ptourin]

I'm hoping I can get some pointers to jumpstart my troubleshooting. Some time ago I built a MS 2.2/MSII V1 [1.31000] to put into a '73 Volvo 1800ES. I had to stop just before the installation was up and running, and I haven't worked on the car in several years. Next week the car is going in to a local shop run by 2 friends, where we'll finish the install. So I've been spending the last several days getting caught up and trying to remember a bunch of details.

I have the MS on the bench, with a MegaStim running off a 12vdc power supply. When I first powered it up everything on the Stim worked - flashing LED's, etc. I fed the MS to my MegaView, which also worked. I downloaded TunerStudio, which wasn't yet around the last time I played with the MS. It read the MS and identified that I needed a 1.31000 file. It fetched it, and the TunerStudio display then worked correctly with the Stim - all Stim pots worked with the TunerStudio display.

At this point I started entering configuration info. I made several changes and clicked "Burn" after each change - the changes were saved. But at some point the process went south - the Stim LED's stopped working and only the Pump LED lights. I unplugged from the PC and plugged back into the MegaView - same Stim behavior, and the MegaView displays nothing.

Before starting to dig in, is there anything obvious that I should be checking? I've been away from this for a long time and I don't know TunerStudio at all well, so I'm hoping that someone who's presently deep into this will see something I'm missing. Thanks - Peter

I'd try reloading firmware and loading your last known working MSQ file.
