hey guys. if the speed limiter is raised up to 255 does it disable completely or just raise to that speed
if its set at 255 is there a way to raise it further obviously for the simplest way after a diff change
can it be raised further in the hex or do i have to turn off the fuel cut timer which stops the rpm limit too
thanks rod

Re: VR AUTO 11B speed limit Q
It will need a code patch to bypass the speed limit and keep the rpm limit. Change address 0xACC6 from 0x24 to 0x20 and will always say the speed is ok.

Re: VR AUTO 11B speed limit Q
Hi guys i dont know if there is any revelance to this thread but i have just noticed my speed only goes to 120 klm then starts to go backwards even though boost and rpm are still climbing ? its all abit hybrid as its in a hj tt5l turbo 400, 808 with vl400 nvram 12p and autometer speed sensor. I am wondering if it has a scaling issue any help appreciated.

Re: VR AUTO 11B speed limit Q
i used to have the same issue with the torana, i never worked it out but i did wonder if it was something to do with not having the divider circuit in the dash ....
