FG Turbo TR6060 TYRE SIZE CHANGE ISSUES
Hi everyone I've got a 2014 Fg Mk2 xr6 Turbo ute with the 6 Speed manual. I've Changed wheels and tyre size and tried to calibrate the change as the speedo is 4km out at 100kmph. so when the speedo reads 100 the vehicle is actually doing 104kmph. I calculated the Rotations Per Km to be 483 RPK the tyres are a 295/30 19". I've tried changing this setting in the tune and Writing the entire tune and it doesn't change a thing (still 4 ks out at 100kmph) I've turned the VID to disable also, I've even tried changing the figure dramatically and it does not change anything. I sent a email to Hp Tuners Support and done everything they have requested, loaded BETA software to my laptop and tried all things requested and still no go. This has been going on since July and I just want it sorted. Hp Tuners Support last said it has been sent to the engineers to asses but that was on the 5th of September and I've emailed them for an update and have not gotten a reply, Just wondering If anyone else has come across this before? Thanks Justin
