Size of megasquirt vs OEM ECU?
I'm looking to run STS2 next year and I'd like to megasquirt my 94 to get some extra power out of it, but there is one hitch. The megasquirt ECU must fit into the OEM ECU case and use the stock inputs and outputs(stock injectors, stock O2 sensor, stock CAS etc). Does anyone know if this is possible? I've read through the DIYautotune article so it seems that using the stock sensors/injectors/spark is straightforward if not plug and play, but what about the size of the megasquirt board vs. the OEM ECU case?

I believe the PCB board will fit but I am not sure about the height of megasquirt. I will be able to let you know later today. I plan on starting my install in my 94 and should be able to tell you how it goes.

I really thing it comes down to being to tall. With MOV1 and the map sensor it jsut seems like it wont fit. I will be able to give a good response in a couple of hours when I put them next to each other and see.

i dont think height is an issue... might have to adjust some components... but what about the vaccum line for the MAP sensor on the MS board??? If you are trying to make it apear totally stock, that will be hard to fake, my sugestion is you will have to use some of the unused pins on the stock connector and have a remote map sensor that you hide in the engine bay, then send the signal through the unused stock wiring to the stock looking ecu... This is an interesting project... i like it!

I believe the rules allow anything inside the stock case to be mucked with... as long as nothing outside it is changed.

STS2 is a class in SCCA's autocross division. Basically it's a street tire prepped class. (you must run street tires but springs/shocks/sway bars are free as are headers, and catback exhausts) There is a provision for remapping the ECU by either hardware or software which means that anything inside the stock ECU box is free, but you must use the OEM sensors or "signal modifiers"

Here are some pics that I promised. If you want more I can take more tommorow.
