MS1 or MS2 on a 90-93?
did you look on the first page? I posted the required mods. I had to swap spark A and Spark B however (Not shown in my writeup or pictures below).
here's mine:
My issue right now it my battery in my laptop sucks, so I need a power inverter to actually go out and fool around with my MSII unit.
But so far it's driving and idling very smooth. this new VE Live feature in TS doesn't hurt either.

Unless you're running sequential injection I'd stick with the 2xxx series until 3xxxx comes out of Beta IMO.
2xxxx and 3xxxx are identical the difference is which will run sequential injection/ignition.

ok I did the sprark inverted mos and the car runs fine (no pop at least.!!!)


I used the megastim to change to spark inverted, the car start and everything runs fine.
Then I modify the board to install MS-2 but now i can't connect the MS to the computer to install the firmware.
What I'm doing wrong?

(by the way, I remove the "floating" resistance after the photo)

Please help!
