Anyone else using MegaSquirt on a LA motor?
MS3X, full sequential fuel and spark using the Jeep cam sensor, LS coils with custom brackets on the back side of the intake. Once the air cleaner is installed, only a keen eye will notice no distributor.
I've been very happy with the system so far. I made the entire engine harness. The most time consuming part of getting the MS3 setup so far was the IAC. I'm using a 4 wire stepper motor style. It took me a while to figure out that while it will move in and out on using the test function, that doesn't necessarily mean its wired correctly. It would initially raise engine RPM as the engine warmed up instead of lower it. There is a function in the software to tell it the direction it needs to move, but that didn't solve my problem. I believe it can be wired one of 4 ways. I figured it out after connecting it the 3rd potential way.
