Updating flash to ZA1JB01D with OFT - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

TheLemperor · 02-11-2023, 10:59 PM

I have a 2013 automatic scion FRS and am currently on stock ZA1JA00D. From my research, I read that ZA1JB01D is the most up to date rom for my car.

Is it possible to update my ecu to ZA1JB01D using my OFT, and if so how do I go about it?

The OFT came with the car so I am still a beginner with tunes and how to operate it.

Thanks in advance!

Don't worry, oft Ots tunes are cal-id hacked
You already have at least a B01D despite the name, if you are using a Ots tune currently

Oft V4 tunes are based on European ROMs a A00D oft tune will actually be a euro A01I based tune which has the important updates same as a B01D

Oft doesn't let you update the stock rom only the tuned ROMs are updated if you wanted to update your car to start with a stock B01D, you would need a tactrix cable
