I know it is NOT in mine!
Not sure how well the software adjusts to lower octane Super.
I was all for it, 'till I saw the 94 octane gas requirement for the E36 M3's.
Now, I'm not sure...don't want to cause engine damage or keep fouling the plugs or whatever...
If the software adjusts itself to the lower octane automatically, then what's the point of using it - where is the advantage???????
Except for the deletion of the speed governer, which can already get me into a whole lot of problems with the cops.
