The need to ground the IAT, CLT and TPS at the ECU is obvious, but how critical is it when using a remote MAP sensor? From what I can tell these are far more comparable to the WBO2 sensors - you give it power and ground, and it sends info back along the signal wire.

I'm asking because I might be able to make 12v MAP modules rather more cheaply than what the 5v 2- and 3-bar GM sensors are going for on EBay. If I can use an entirely 12v system, this eliminates the annoying possibility of cross-wiring 12v and 5v wires, as well as saving connector pins.

A ground offset is a ground offset - I would much rather have the MAP sensor grounded to the MS to minimize it.

Can you use the MapDaddy 4 Bar MAP Sensor with Barometric Correction to the microsquirt?

Seems to be good for 2-strokers..

I don't see why not. You'll need to come up with a way of mounting it - the Mapdaddy is meant to be installed inside the MegaSquirt case, and isn't intended to be left out for the squirrels to munch on. One of the smaller Hammond 1551 cases should do nicely; you'll want to measure it before ordering anything.

Dontz125 nailed it - the MapDaddy will work OK enough; you just need to come up with a case for it.
