java300hp

I am in canada, this car came up from usa , the ecm engine, had cap issues and water damage, I repaired it to the point where car would run, but ruff, missing, no codes, So got an parts car 1995 sc400 canadian one, pulled ecm and put it in mine. Runs great, issues is egr fail 71, canadian car had electronic egr control, mine has vacuum and relay control. So now I am looking for an fed usa ecm. 89661-24230. 175000-4424 12v.
BTW if you use an newer ecm disconnect the cold start injector.. makes it not flood..
