Matching Spare TCU part #?

[Greg.Annunziata]

Hey Guys,
I have a 2019 G70 3.3t AWD

I am looking to purchase a spare TCU so I can tune it. My stock part number is 95441-4J620, does my spare 100% have to match that? Or can it come close?
Ive heard mixed answers. But I ordered a 95441-4G040, installed it and my car did not start.
Sent that one back out, and I am now looking at a 95441-4J600 for double the price of the last one I bought Someone please save me the trouble of test and trial and lmk if it will work with my car.

I did the test n trial...
Sent back 2 TCU's to find this out lol
Does not have to match fully, but I believe it has to match until at least the first 2 numbers/letters in the second segment of the part number. For example, my stock one was 95441-4J620 (branded Hyundai), and I am now running 95441-4J....(off of a stinger...branded Kia, Tork tuned)

Reviving this.

Does anyone know if a g80 or g90 TCU will work in the G70?
