OK, so I've had nothing but problems trying to get my speedometer to read correctly. It's been going on for about..well almost 8,000 miles according to my horribly inaccurate odometer! haha
2005 GTO 6-Speed
3.89 rear gear DSS 9-inch conversion.
*built trans at the same time as rear*
I've changed the gear value, nothing. The tires, nothing. Then I tried an SCT handheld that simply asks you what gears you have so it's fool-proof, NOTHING!
HP Tuners will read and write correctly and the changes are going in, but the speedometer and odometer are showing the incorrect values. Approximately 10mph off.
I'm being told I have to recalibrate my DIC, but I don't know how or where to do that. Could anyone shed some light on what I could possibly be doing wrong with this car?
