Jb4 latest Firmware

[absaifan]

I had trouble finding the latest Supra specific firmware as my JB4 came with V11.

Let's keep this thread for the latest firmwares

Since this forum does not allow upload of the. Hex files, I uploaded it on the n54 website.

Unfortunately I wasn't told what are the changes, I barley found the firmware, but I'm quite sure it's more capability or bug fixes taking in consideration its a new platform anyways.

93

I am not an expert and it is always recommended to post your logs in N54tech. However, with that being said, I have 91oct and was “approved” to run map 2 by Terry at BMS with a splash of e-85.

With that info, I would say you are safe for map 2. But again, something happens, I don’t wanna be the guy you come after.

I am jealous....how does 3 feel?

 

[iceman21_23]

quick lol

Map 3 feels really great with boost but I noticed it pulls timing quite considerably especially after getting hot with several pulls, map 2 feels a bit more consistent with higher timing for me on 93 octane with the dp install.
