right now trying to help a local with his tune where he converted his 4l60e to t56 swap. i read that a segment swap is needed for this to work since his speedo is showing half the mph of what is actually going based on GPS. for example, if the speedos showing 10mph he is actually going around 20mph. my current hptuners version is the pro version v4.6.3. i read that a segment swap comparing with a bin file for a manual is needed and using the segment swapper but that option in the drop-down is greyed out and that a hp staff needs to process this change? could someone shed some light please?
