[silentvoice71]

ok i found a ecu for a decent price its a code 63.Is there any way on the SN of the ecu i looked in the faq and some of the other helpers we have on here and ive searched but ill keep lookin and tryin.

ok i found out the 63 is the auto ecu i love google .ok now my questions to you guys is how interchangeable are the 62-63 ecu's??????

[SpeedRacer1]

They are interchangable, idle may be higher.

[silentvoice71]

do i have to mod or mess with anything like some stupid little wire lol. Thats seems to be everyones demise lately is 1 little wire

It should run the car, if your idle is high I will tell you a wire you can try to bypass. But it should run just fine.

I've been running a 63 ecu for a while now. It does cause high idle, about 1750 rpm. If the IAV is adjusted to normal idle rpm when warm, the car won't stay running when cold. Details on wire bypass? Thanks!

This info is try at your own risk. I did it on my car and ran an auto ECU for a couple years with no problems, it dropped my idle from about 1600 to 800 solid.

Try cutting the light blue wire that runs to the IACV. You can either cut it in the engine bay ,on the 4 wire connector, or cut it by the ECU. I would suggest cutting it by the ECU, that way if it doesnt work you can re-solder the wire. Pin #113
