Will im back to work today so i don't have much free time until sat. But i will be eliminating the c101 before i grab a 90 ecu. I will give a report back asap. Maybe ill get the itch and knock it out on a lunch break. I get a hr lunch so even if i don't get it all at lunch it'll only take a few mins to finish up after

wish there was some nice finds for the 97+...like obd2 to obd1 conversion harness or something

Aw, come on. You're not jealous of our old antique crap are you?

rabies

lol kinda. obd2 ecu can emission and be picky and throw codes for silly things these days. easier to tune turbo or supercharger off obd1

Possibly dumb question, ecu under driver's side dash correct and not in engine bay?

cruiser54

That's the dumbest question I've ever heard!!

LOL. JK.

The Renix Jeeps had the ECU mounted under the dash up and to the right of the gas pedal. When they went to a PCM in 1991, they were located in the engine bay.

I'm looking forward to your report back after replacing the ECU. Did you see my ****-poor pic of the easy way to remove it?

unidentifiedbomb

haha i did, had to zoom out 200% to make it clear. It's just mounted by two bolts? I can see about replacing it next week. Then c101 delete in two weeks.

cruiser54

2 nuts hold the bracket to the dash mount. That's where you wanna remove it from. Swap the bracket to the "new" ECU by removing 3 bolts.

Thanks cruiser, will report back pm with update if i get to it next week.

My two bracket bolts were very tight. Found it best to use a ratchet wrench.

cruiser54

You mean "nuts"? And if so, a 10mm ratcheting wrench is the way to go.

1arunem

Yep, meant the nuts on the bracket bolts..
