Flashed Competition Steering and Diff. On regular M5

BIMMERPOST
     Featured on BIMMERPOST.com
So today I have succesfully flashed and coded a normal M5 Power Steering ECU and rear Differential with Competition software.

Initail feel is that it is a bit more progressive and slightley harder, however will test and try it out for a bit and come back with a definitive conclusion.

So a little update, I have flashed a few more F90's, for the rear diff you cant really feel the difference like I also couldnt feel the difference in my F80 when I flashed the GTS software. But maybe if someone who takes their F90 on the track could have more feedback but for now the results is on the street you can feel the rear diff acting any different.

As regards to the steering, it is mixed emotions, some say they can feel the steering being a bit more progressive and some say its the same, or they would need to go back and forth between flashes to try to change.

So I would say it is definetly not a major/night and day difference but as it can be done easyily and remotley its up to the driver to decide.

Still trying to figure out if there is any difference betweencars having different Istep software version. So far I did a 17, 18 and 20 Istep.
