Which PCM?

Hello, I would like to know which ECM is on my car (2.0 Turbo 2018)?

According to quick search: A 2018 Chevrolet Camaro 2.0 typically uses a Transmission Control Module (TCM) with part number 24289543

https://www.gmpartsdirect.com/oem-pa...odule-24289543

To Clarify: T87A is a 5th gen TCM that is compatible with 6th gens and does not require unlocking if I remember correctly, the T93 is an option on the LT1 SS and ZL1's and can be unlocked from HP Tuners.

The 2018 Camaro 2.0 did not come with a T87A or T93 as far as I have found.

Thanks for your reply, the Transmission Control Module - GM (24289543) looks similar to the T87A.

Did you try looking at the ecm? It usually says what it is on the body of it. Like in-between the cooling ribs

Ecm is for engine
Tcm is for transmission
Pcm is for both

Hello,
Here is the ECU that is on my Camaro, what I find strange is that there are two plugs in one direction and one in the other.
Is this still the GM 12653998 ECU,

If you want to make sure you’re getting the right modules there is an easier way to do it. Just call any Chevrolet dealership in the country and give them the last eight numbers on your VIN and they can tell you the exact part number that you’re looking for.

Unfortunately in Europe there are no more Chevrolet dealers.

Well, that is a bummer…. I wonder if you could find dealer that responds by email here in the United States?

Just an idea.

Hello,
I have a problem with the pin of the ethanol sensor plug that goes on the PCM, it does not fit, it is too wide. (I put it in myself)
Is there a specific dimension for the PCM pins or do you have to enlarge the hole and the pin will not fit?

No, I don't dare, for fear of doing something stupid.
From a video capture, it's not the same at all.
