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
Details
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?
Thanks,
Kevin
