Need 3.90 gear ratios
I have just installed Harry's LapTimer on my iPhone and I plan to use it on my next session.
I am now entering data about my car. It is a C5 (not Z06) with regular gear box and a 3.90 rear diff. The LapTimer is asking for each ratio per gear.
I have entered :
1st - 2.66
2nd - 1.78
3rd - 1.30
4th - 1.00
5th - 0.88
6th - 0.50
Could you confirm it is right or direct me to a chart? I don't find one.
