My car must be some kind of unicorn. It is a 1995 model car, but while diagnosing a CEL that came up (Ended up being the EGR) I was poking around and noticed that my car had a crank angle sensor on it. So bent over backwards with a head lamp on and even though there was no mounting location for one, as I poked and prodded and gently tugged on some wiring under the dash out falls a ODBII port.

I pulled the codes just like you would on an ODBII car and ended up mounting the port using a couple of bolts through the bottom lip of the dash. So now that my car is running great I obviously want to **** all that up and learn how to tune a Megasquirt and install one on my car. It has a header, intake, Borla exhaust, Fidanza aluminum flywheel and F1 Stage II clutch. I'm going to go turbo in the future and I figure the first step (seeing that on my last turbo build I just used bandaids) is to learn how to tune the MS.

So the question is, since I have a 1995, but I must have one of the later build dates where Hiroshima was switching the cars over to ODBII, should I buy an MS for a 1996-1997 car?

Thanks for any advice. Sorry for being such a noob, but I couldn't find anything on my particular situation.

 

Since I don't know the answer, I would try to find the engine code on the ECU, or take a picture of the wire colors going into the ECU connectors and cross reference to pinouts on trubokitty.com.

 

Thanks for the response. I'll try that.

 

I've got a weird mid 95 car but mine is still obd1. i had to swap a pin on the ecu harness connector to make my tach work.. if you've got obd2 i would probably go 96-97.. but i cant say for sure. i think the main difference was the coil pack.

 

compare harness/ecu plugs to known obd1/obd2 cars

 

its a 95.5. you'll still want a 94-95 ms3.
