is there anyone that lives inthe area of St.Louis, Missouri that might by chance have a mr2 tubro.. that we could see if our ecu works in your car.. just to make sure if its our ECU that is bad.. ?? like that would really help alot cause we are about to purchase a new one but we want to make sure its bad before we go out and spend 300-800$ on a 3SGTE ECU .. anyones help would be gladly apprieciated..

pm me if you can..

I'm not local so I probably can't help.
But usually a used MR2 turbo ECU will cost you $100 or LESS.

and where should i get one.. everyjunkyard around here they have zero nice cars.. they all have the typical crappy saturns, hondas , and camry's but no mr2's very hard to come by up here

so i picked up a ecu used from a guy on mr2oc forum for 100$ said it worked wehn we picked it up from his house.. brought it back home still no good results.. still doesnt start fuel and spark cut.. no rpm/signal either.. of course what else could go wrong right .. i know once it gets started though were gonna need some new tires.. theres alot of anger thats going to be taken out onthe car for 4months of brokeness!

i hear you on the four months of brokenness, im going through a similar problem, but you should nto take it out on the car, mostly cuz your not even sure whats wrong yet. im not a mechanic but its worth the diag. fee to find out whats wrong so you dont buy parts you dont need.

What's wrong with it?
Is this stock MR2 turbo or swap?
Does it throw any error code?
You need 3 things, air, fuel and spark.
Try eliminating each of these from the question.

umm the entire motor was race fully built.. bored .20 over JE pistons. Gen 2 longblock.. head was RACE Spec.. ported cut polished etc... well just figured out the reason theres no fuel and no spark.. haha funny actually. busted the camshaft in 2 to a 2 piece.. lol distributor side.. is now a 2piece camshaft.. right after teh first 3 lobes.. snap.. crack.. big problem now we must remove the head and check to see if our pistons are scarred.. hopefully not.. just praying that the pistons are fine. cause thats more problems then we need. i guess @ 19psi boost the gremlins for camshafts start to play.. yes it threw an error code for no spark . i dont rememebr the number.. now has spark bought a new ecu.. adn its getting spark i should know i got the sh9t shocked out of my finger today.. lol was good times though alittle electricution never hurt anyone.

well its now a pricey fix.. camshafts well they arent cheap and since im figuring were going to be replacing both of them. cause it wouldnt be right jsut doing one.
