it does now in MS3 firmware, thanks to the miata community--not to mention VVT support, and a/c handling.

Cool!

Once I get the MS2 working with MAP, if I can't get the MAF function to work I'll sell the MS2 and build a MS3.

I'm actually looking forward to doing the parallel wiring in the DIYPNP box. It probably wouldn't be too difficult to install a couple switches; one to select from alternate maps, and another to select stock ECU or megasquirt.

I will probabably wire a DB25 to the diypnp extension board and use it as a pass through to the stock ecu, with OEM connectors from Mouser. Then I can have megasquirt provide control by intercepting the signals in the box, and make it switchable.

if you're running parallel--gasp--i see no reason for the MS to touch the alternator controls, imho.

When I develop the parallel wiring, I may relinquish control to the stock ecu. I wanted the ability to run standalone.
