MS45 Doubled MAF Sensor Range

[Renovelo]

We've added two tunes above for the 525i and 530i. These will require ByteTuner v1.19.0 (or newer) which we just released. Be sure to have your automatic updates enabled in the Settings.

HW:7561382
ZB: 7549091
SW: 7549345

Are you sure this tune isn't the following:
HW: 7561382
ZB: 7561528
SW: 7561529

Upon inspection, this is what it appears to be. We don't see any SW variants which start with 754xxxx that are associated with HW7561382.

I'm sorry you are correct there was info that I didn't see.

We've updated the first post with a modified version of a stock tune. Nowadays, we're not really applying the hack to customers' modified files. Instead, we're applying it to stock tunes so everyone has the same guaranteed good starting point. Just migrate your changes over to this tune and you should be good to go!

is there a version of this available for the m56?

We don’t have one for M56 engines yet. Can you email us more details of your DME? Specifically, do you know the ZB or HW variant?

I have a M54b30 with MS45.0 running a VF Engineering supercharger kit with their tune. I have the standard MAF, so would you be able to modify my files to double the MAF sensor range?

As we mentioned a few posts above, we're not offering this service anymore. It should be possible to take one of our stock base tunes where we've applied this hack and carry the changes over from your existing tune using ByteTuner.
