Original Diff Ratio in Manual 3.46

Diff you can change to Manual 3.73, 3.91

First ask your Holden Dealer to see what PPK are on you car, via the Tech 2, note the number down.

Say you get 6301, next divide with the Original Diff Ratio, say is was 3.07.

6301/3.07 = 2052.442996742671009771986970684

Next we need to multiply with the New Diff Ratio, say 3.73

2052.442996742671009771986970684 x 3.73 = 7655.6123778501628664495114006515

just make it 7655

As the car computer limit is 7500, it is the limit you can adjust the PPK's.

So enter 7500.

The computer is limit to 21% so a 3.46 you would be able to get it spot on.

Let try it now.

Next get your need to check what PPK's you have Original before you start

Here is the list below look up your car with what diff you have.

Say it is 6301 PPK's

Next we need to divide the 6301 ppk with the Original Diff Ratio 3.07

Next we need to multiply with the NEW Diff ratio.

2052.442996742671009771986970684 x 3.46 = 7101.4527687296416938110749185668

Just make it 7101ppk's

this is the NEW PPK's number to be entered into the computer via the Tech 2

Because of different tyre size, just use this equation, and don't forgot to make sure you use the Original PPK's via Tech 2.
