im about to rebuild my LSD and change the gear ratios from 3:08 to 4:11 i know this greatly affects the speedometer so in a VR what do you need to change. i know the newer models need a chip to change the pulse from the gearbox to the ECU to calibrate the speed and in the older models its just simply changing a cog to calibrate. Does a VR come under an older model style calibration with a new cog or a newer model style calibration with a chip. or Neither? Have not been able to get a clear answer. any help would be greatly appreciated!
best way in a VR is with a speedo corrector. Most people buy the kit from Jaycar (which comes as a circuit board and components and needs to be soldered together). Then it is just a matter of connecting it up, cutting into the wire from ECU to speedo, and calibrating it properly. I believe there is a thread on here somewhere on fitting one.
manny. alright cheers mate. how much do they go for ? i know a fair bit about circuits and electrical and wiring jobs so should i be able to give it a go meself ?
found this > Speedo Corrector MkII Kit "Kit Back Catalogue" - Jaycar Electronics do i need to get it on the dyno to adjust or ?? how does it set that im using 20" wheels and diff gear ratio to 4:11
But a dyno would be way more accurate yeah ? i attract enough police attention as it is so i wana make sure its spot on
Where in canberra can i get it done besides dickson specialty instruments, their wait time is ages and pricey for something fairly simple
