OFT v4.01 vs v4.03 noobie question
 

Recently bought a 2017 BRZ with catless header, and an aftermarket cutback.

I also got a OFT (V1) and hooked it up to my car and found that it is tuned with stage 2+ V4.01.

On the OFT website, for 2017 BRZ, the latest version is V4.03.
Their website doesn't really have any details on what was changed between versions.

Is there anywhere that highlights the changes?
And is it worth re-tuning with newer version?

If you bought the oft separate, you are fuc*Ed but if it came with the car, you are good.

You can just load the 4.03 tunes on there. A better option is using Wayneroms tunes for just a couple bucks.��

I bought the car with the OFT so it's already married.

I'm just wondering what kind of benefits upgrading to 4.03 will have against 4.01.

There's no "release notes" in the OFT website.

Think you're better off asking in the OFT facebook group.

Cam tuning is optimized with the 4.03 and a few other features are enabled such as launch control and flat foot shift. I helped do some of the beta testing for the 4.0x tunes and would recommend upgrading to the new tunes.

There are no difference between the V4.01 and the v4.03. They just added some more CalId's.
