Hello all. I am attempting to calibrate a speedometer in a restomod with a LS1/T-56 combo. PCM is from a 98 Firebird. Tire/ gear wizard only has one field to edit and get an error when updating the field.
Hello all. I am attempting to calibrate a speedometer in a restomod with a LS1/T-56 combo. PCM is from a 98 Firebird. Tire/ gear wizard only has one field to edit and get an error when updating the field.
That field is the tire diameter in inches divided by the gear ratio. For example 28/3.73 = 7.51
Thank you so much
