Jap. engine u.s. ECU
I am getting an 86 rx-7. The guy that is selling it put in a brand new engine from Japan because the old one had allot of miles and a broken oil seal. He says that the only thing that bothers him mechanically about the car is that it idles at a really high rpm (how high I am not sure) because it is still the original American E.C.U. and the engine fuel sensors are Japanese. I am a collage student and I know that this will increase the already high gas bill. would buying a new ecu do it? What is the best course of action?

Re: Jap. engine u.s. ECU
Umm..That A-Spec ECU should run that J-spec motor just fine. Probably wont even see that much of a difference in fuel consumption, if at all. What is the car idling at? The idle speed is not entirely a function of the ECU.

yea it may not even be the ECU, could be something simple like the timing chain or whatever, hard to really know

ofcourse I'm not joking, the timing chain is the start of all problems...

ahhh you shouldn't have told him, it'd be funny when he took it to the shop and said "yea can you check the timing chain for me?"
