Hi I have a '94 Firebird Formula LT1 and my Speedometer reads 3-4mph faster than my GPS speedometer App.
I have 3.23 gears, 4L60E automatic transmission, 315/35ZR17 Nitto NT555 G-2 tires on 11" wide rims, tire height 25.67" 810 revs/mile
Can anyone give me the speedometer Scalar numbers as I cannot open the speedometer calculator
Speedo Scalar-Base
Speedo Scalar-Divisor
Speedo Scalar-Scan Tool
Stopped vehicle VSS Pulse Delay
I am using Tuner Pro to tune my car
I would really appreciate the help
thank you
