M6 to TH350, check my speedo calcs please

[96gt4.6]

Getting ready to do a car that has an M6 to TH350 conversion. Just wanted to make sure i'm not missing anything in case I run into a suprise after attempting to correct the speedo.

Here are my calculated values to enter into the tune:

2002 Camaro SS

Tire Size: 275/40R17
Gear Ratio: 4.10
Tire Height: 25.7"

Installed Transmission speedometer drive gears are for a 3.31 gear ratio. The tailshaft gear has 9 teeth and the cable drive gear has 22 teeth = 2.44 ratio.

He is using a Dakota Digital pulse generator that produces 8 pulses per revolution.

VSS Pulses/Mile: 10550
Rev-Trans: 3.28

Final Drive Ratio: 4.10
Trans Revolutions/Mile: 3217.84

These calculations were made using the information provided by Chris at post #2 here:

Look right?

Everything worked out, Perfect! The formulas Chris gives lead to a perfect tune by the GPS for both his slicks and street tires!

Although since he had a speedo gear ratio and a Dakota Digital pulse generator to go through it made for a little more math, but was ultimately very easy!
