GPEC5 replaced by GPEC2 ?

[jwolfejt]

So I was telling my dealer that I wanted to make sure that they have a replacement ECU before i take it in for the recall (on hand - so if they fry it i get a. new one without needing to wait for months) and low and behold while i was googling: https://parts.chryslerjeepdodgecity...e-Engine-Controller/109248676/68568654AA.html
"
THIS PRODUCT HAS BEEN REPLACED BY

MODULE. Engine Controller.
Part Number: 68568654AB"

Can you swap to a GPEC2 PCM ? kinda weird.

Mine, just built about 3 weeks ago, came with this -

You do realize those are the same part number, right?


SKU: 68568654AB
Other Names: Module
Applications: 4x4.
Replaces: 68568654AA

This is the core part number - 68568654
The AA to AB is just a revision.

And that number is for 21 and 22 models, not 2020

What makes you think one is a 2 and the other a 5?

They don’t use the same connectors, do they? That would be a non-starter right there.

That, and there are multiple GPEC2 - there's a 29 bit, there's a GPEC2a

Well i guess the AB revision was probably just a software update , i would be willing to buy one and send it off to someone who can help unlock these.

It's impossible to tell what such a minor revision of the part number is. Could even be who made the case it's in, but normally going from AA to AB is a small change, sometimes only those making them knows.

Software updates rarely roll the hardware part numbers. The PCM will report a software part number that is exclusive of the hardware part number.

I hope mine gets fried.

GPEC5 is not super charger compatible GPEC2 is.

Can't simply swap. They will replace it with the same version. Take a look and compare pin-outs and function. Besides...the compatibility is because the sc people and hp haven't caught. It's not because the hardware can't handle it.

Dammit shadow. Stop crushing my dreams with reality.

The 392 wrangler also uses gpec5, so I am sure that someone is working on a method to unlock these pcms my understanding is they can read them but havent found a way to unlock them yet

Hi everyone, for 1 years I have been looking for information to install a tvs1900sc, my problem is ecu gpec5. really a big shit. I decided to exchange the gpec5 ecu for the gpec2a one with the wiring of the gpec2a connectors. I am waiting for the gpec5 and gpec2a connection diagrams to make the transition. if all the wiring is identical and the two diagrams can be combined, I will cut the files of gpec5 and combine the connectors of 2a. I cross my fingers, after all, it's the same vehicle, no change in the standard components from 2019 to 2023, only the ecu for lack of supply.
