Megasquirt questions, timing module...pulling the CB Performance, EMS and replacing it w/Megasquirt.... Options

[Joe Bob]

So like the title says....I'm pulling the CB Performance EMS and replacing it with the MS. I find that there is a lead for timing mods but I don't see and adjustments...I lalso find that MPS was disconnected/malfunctioning which is the reason for my full rich conditions.....

Anyways, is there a timiing management module that will plug into the MS box and allow adjustments to the 009 dizzy I have or should I just use the centifugal advance that's in it...

No, it can't. It's an entirely different board. They moved a lot of stuff around, went from a 2-layer to a 4-layer board, and lined up all of the stuff that requires a heatsink to the top of the board where you can have one long strip of Al acting as the heatsink. They also added the flyback circuit (previously an add-on) so you can run low impedence injectors w/o an additional board or external resistors, and they added the ignition driver on board. They also substantially improved the tach input circuit, curing a lot of problems people had previously.

You CAN drive ignition with a 2.2 (or even a 1.0) board, but you have to use an external module (GM HEI or the equivalent Bosch part, usually), and you have to hack on the board a bit.
