i ended up purchasing a AEM EPM to run as a cam trigger. This was easily installed onto the megasquirt directly using no filter circuits on the megasquirt. I then installed 4 LS1 coils using the megasquirt to drive them directly, and sequentially. Currently running MS2 on the latest version (3.3.3), with some low impedence 1000cc injectors.
It runs great, has some furious antilag, very easily tuned using the autotune feature in megasquirt. its been very reliable with easy starts and such (which I credit to the mega coils), even on E85/E90.
Timing map is pretty rusty right now in boost, very conservative 11 degrees across the board, but it pulls good on breakin boost of 7psi... Just putting around with it as I do not have much time to drive it and no plans to race this year.
For the wiring harness, I used an OBD0-OBD1 adapter to go to my stock wiring harness in my CRX, and ran a megasquirt 27 pin connector in place of the obd1 connector that would normally go to a P28.
Is it better than a obd1 setup? I say yes, as this car is setup to run roadcourse, and I am able to use ms2 traction control, boost control by speed, and easily and cheaply run the LS1 coil setup. Real time tuning and logging, and support for my tablet bluetooth dash without any extra money being spent. Total cost with the AEM EPM and LS1 coils swap, connectors, wiring, etc, was under $350 as well, which is cheaper than a S300/neptune box... Plus the obd1 distributor and adapter harness not included, which would be over $100.
