Just had the diff. ratio changed on my HSV VZ LS2 GTO & thought I would share my experience on how to re-calibrate the speedometer. Unlike the earlier model LS1s, there does not appear to be an input table (at this stage anyway) in Flashscan V2 to automatically do the pulse calculations for you. Changing the diff. ratio under Speedometer>Ratios has no effect on the speedo values so you have to manually calculate the Speed Sensor Pulses & Transmission Output Shaft Revs & adjust parameters: {H01043} + {H0144}. This worked for me & appears to be accurate:) .

Cheers,
