E98 Tuning questions
Hey everyone, appreciate all of the great discussions on the forum. I recently paid for a tuning service using another software kit and was left rather.... disappointed (for a few reasons). The tune is great, but there are some small things that I want to change on my own. Talking to the tuner, he mentioned that if I flash later using EFILive, there is a possibility that the ECU gets bricked. IIRC he said the OS differences were the reason for this.
EDIT: Talked to the tuner again and he meant that if the dealership were to reflash my truck to stock (an example I gave him for wanting to be able to reflash on my own) its possible the OS version will change and he will have to 'redo' the tune on the newer OS. This actually makes more sense to me now and likely invalidates any concerns I have below... Would be nice to just have a sanity check though.
Long story short, I want to know whether he is BS'ing me so that I would _have_ to buy his service(s) in future when I want to reflash. My plan when I got my autocal was to have a few tunes with varying speedo ratios for different tire setups. I also wanted the ability to flash my stock tune back on the ECU when needed. I pulled up my stock tune (it was gathered using BitBox) and compared it to an autocal read of my truck after a tune was flashed using BitBox.
Using the 'Full binary compare' I see differences in OperatingSystem/EngineOperation/EngineDiagnostics/System. Might that be the 'issue' my tuner is talking about? How worried should I be? Attaching a rar file of the exports of both binary and non-binary compare difference output.
Really appreciate your time!
