Hey guys, need an answer fast; Could the 1994 MT ECU be used on my 1991 MT 4runner? Will there be any issues to deal with? My current ECU is not reading the O2 sensor, I tried someone's ECU and that worked fine.

I dont know for sure i only have the wiring manual for 92 but i think the pin locations may be different on 90-91 to 92-95. i see most places sale ecms seperated like that. the main difference i think would be if it was a caly car or not due to the egr temp sensor. if you can get the ecm cheap go for it.

I happen to have a '91 ecu here I don't need....

I also have a 91 MT ECU out of a P/U that was working when I pulled it.

Thanks guys. @Wii tarded & 91diesel- how much are you guys asking for it? The one I was looking at was on off road solutions for 20 bucks.

oops just realised that company was closed. It's official...I'm a doofus lol. Let me know how mush for the ECU

Did you plug yours back in and reset it. Maybe it just wasn't a good connection?

@Bigswole; tried that umpteen times hoping that was the case-no luck

I'd take $50 plus shipping. Dunno how much that would be to South America. My zip is 37921 if that helps

Alright. Will work out the finances and get back to you. How do you prefer the payment to be made? Paypal, wire transfer, etc?
