VT supercharged tune rev limter
Just wondering where I would find the values for the rev limiter on a VT L67 tune? I would like to lower it by a few hundred RPM if possible.

Re: VT supercharged tune rev limter
Which bin are you using, as it will be different in different variants of $A5?

ok fuel cuts i have are for vs l67, not sure if any others are the same or not.
4A4D - upper limit fuel cut in drive
4A4E - lower limit fuel cut in drive
4A4F and 4A50 are as above but for park/neutral.
the two after it are for reverse just incase you wanted them, lol!
euqation is X * 25.

No matter what the question is, the answer is always more horsepower!

Re: VT supercharged tune rev limter
VT are in a different place, for variants F, G & H they are:
51CF - upper limit fuel cut in drive
51D0 - lower limit fuel cut in drive
51D1 - upper limit fuel cut in P/N
51D2 - lower limit fuel cut in P/N
51D3 - upper limit fuel cut in Reverse
51D4 - lower limit fuel cut in Reverse
Formula is the same, X*25.
In CXWK all Highs are set to $EC (236*25=5900rpm) and all Lows are set to $E0 (224*25=5600rpm)
