ECU Compatibility

Will any ECU from a truck equipped with an 22RE work if you need a new one?

I was under the impression that there was several differnt ECU's. One for the Turbo's and atleast 2 for the fuel injected models due to the plenum change. but I'm not positive on this.

turbo is different
91-on is different

88-90 used a different impedance injector than the previous generation. I know the connectors are different, I suspect the injector coil and ECU is different, as well.

Give me some numbers and I can check.

From my recent experiences in ECU's 86-87 are changeable, 85 and lower are interchangeable, 88' is all by itself as this is when the injectors were switched over to the hole type from pintle and require a different electrical current. 89-early 92' are swappable and then late 92-95. 4Crawler has used a newer ECU in his 85' without any ill-effects or change in performance. So this could be a varied answer depending on technical vs. real world experiences.

Thats what Esquire812 @ 4x4wire said when I had the same question a while back

I started to track the different part numbers of ECU's and what they were out of but never got any more input for them:

89661-33070 = unknown
89661-35020 = 85 Std 22RE, 5 speed, w. A/C, Cruise
89661-35050 = 86 Std, sb, 22RET, 5 spd, Non-SR5, No A/C, No Cruise
89661-35050 = 86 22RET Auto, w. A/C
89661-35070 = 86 Std 22RE, 5 speed, no A/C, no Cruise
89661-35070 = 86 4Run, 22REC, 5 spd, SR5, w. A/C, w. Cruise
89661-35110 = 88 Std, sb, 22RE, 5 spd, Non-SR5 No A/C, No cruise



Xtra = extra cab
Std = standard cab
4Run = 4 Runner
SB = short bed
LB = long bed

I installed a '87 22re in my '85 efi x-tra cab.Used the 85 ecu and everything else was from the '87.Had one extra wire in the connector at the ecu.Been running fine for the last 12 years.

hoping it will work as a spare for my 85 4runner

I put an 070 into my 020-equipped '85 and it worked fine from the short test I gave it. No codes, started and ran fine. Its my spare so that is all I was looking to find out.

IT Works in my 85!! I passed smog too

the 89661-35020 that was in my 85 runner gave me an engine light, that could not be troubled shooted. swapped inthe 35070 and No engine light and everything works and runs great!
