Anyone else using MegaSquirt on a LA motor?

I haven't accessed them lately, there were some "example" builds somewhere on the MS site. Seems to me there was a 318. (Cough gag) SB Chev would be similar. I think the MS sensors are pretty much GM based, temp, TP, etc.

They are GM based sensors.

It is a difficult system to build, that’s for sure. The main problem is that MS is so universal that there is no designated manual for every possible engine combination. But it is well <$1000. You can pay a lot and learn very little, or pay very little and learn a lot.

The capabilities of MS are most likely more broad than the others - although I’ve never compared. With MS you can run all different kinds of outputs and take in multiple inputs from anything you can dream of. Flex fuel, run cooling fans at designated temps, run boost control, propane, knock, o2, the options are endless.
