will 94 engine computer work in 96 cruiser?

[ejames82]

hello,

in all fairness I will be unfront and let you know that I will also be posting this request on other great forums. any info worthy of sharing will be distributed to all forums I go to. all forums will benefit.

I have a 96 land cruiser, 80-series. a guy I know insists he has an engine computer that came out of a 94 land cruiser, 80-series. he wants $50 for the computer.

I don't NEED an engine computer for my cruiser. it runs great, but to have a spare at that price could never hurt.

I have some questions:

1. would this engine computer happen to be plug-and-play, meaning, just plug it in in place of the original with no programming needed, and obviously, work well?

2. would there be a problem with the year difference, his engine computer coming from a 94 and my cruiser being a 96?

3. would there be some other difference that would make it incompatible?

thanks.

Don't know for sure but the 96 is OBDII and 94 is OBDI. So my guess is that it would not be plug n play. Don't know what other differences there are but that's enough to not make it worth $50 for a spare to me.

Won't work for the big reason stated above obd 1 vs obd 2. Also no crank position sensor on the 93-94 trucks. I'm sure others can comment on more differences. Not sure why you need a back up ecu. They are very reliable on the 80 series. Only problems have been a few issues with the 1993 model year ecu.

Not even close to working.

Consider this topic closed.

thanks for all replies and without a doubt the 94 ecu will not work. below is relevant (possibly helpful-not necessarily in this circumstance) info to be distributed to all forums as promised.


96 is OBDII and 94 is OBDI

no crank position sensor on the 93-94 trucks

The specification/part numbers will be marked on the ECU's. You could also type both VIN numbers in to toyodiy to see if the ECU part numbers are the same.

one runs an air flow meter and the other runs a MAF sensor. One has an O2 sensor and the other doesnt.

That would require you to do it. Only the original thread poster can edit the title. John
