TL/DR: Looking for the part number to purchase a used (spare) ECU for my (Canadian) USDM 2019 BRZ 6MT (Red Manifold). I have Tactrix OP2.0 cable.



(sorry for the long post)

Hi everyone!

I have a (Canadian) 2019 BRZ, Raiu Edition (it's pretty much equivalent to the Series.Gray in the USA). It has the funky paint color (Cool Gray Khaki), 6MT transmission, 4.30:1 final drive, Sachs suspension and Brembo brakes. Red Manifold.

I have recently purchased a (genuine) Tactrix OP 2.0 cable and have read my stock ROM. Cal ID is ZA1JS10C. The car has never been flashed (except *maybe* by the dealer prior to delivery) so I know this is a 100% stock ROM.

I have been looking at various threads here and on romraider.com and would like to start disassembling the ROM to prepare definition files and find RAM addresses for logging. I haven't done assembly language and microcontrollers in many years..

There does not seem to be a lot of information about the ZA1JS10C ROM yet.

The OFT guys have published their 4.03 OTS ROM for this Cal ID but it looks like it's a hacked CalID ROM (based on ZA1JK00G as far as I know).



Before I start messing with my car and my ECU too much, I was hoping to purchase a used ECU for some bench testing.

Would anyone happen to know what part number(s) I can search for to make sure I get something that is compatible (at the hardware level at least) with my 2019 6MT BRZ?

Am I limited to 2017+ ECUs?

Am I limited to ECUs from 6MT cars?

Or does it not matter since I have the Tactrix OP2 and could reflash an ECU from an AT car with my stock (6MT) ROM image?


So far, the used parts I have found (eBay), where the description clearly indicates "engine ECU" have the following part numbers:
- 22765AK030 (6MT)
- 22765AK040 (possibly AT, not sure)

Both are listed as 2017.

There are a lot of older ECUs for sale but they have a different part numbers. This leads me to believe there is a hardware change for 2017+, at least for the Red Manifold cars..


Any ideas, suggestions, comments?

Thanks!
