Re: t5 manual speedo
the stupid thing is the error seems to exponentially rise as soon as above 100k. where I had less than 1% error across the broad before.

Re: t5 manual speedo
I used to have an issues with t700 in the Torana, in the tune the speedo would start going backwards from 140kph onwards, but it never effected the speedo!
No matter what the question is, the answer is always more horsepower!

Re: t5 manual speedo
well I have worked out its related to temperature. Today the afternoon was hot, speedo 100% accurate.
I only get this problem in the morning and only cold mornings. Its maybe a mechanical resistance on the speedo when cold. Just like the "normal" sticky fuel and temp gauges when they are cold.
I guess I can install my NVRAM 808 and see if the ECU reads correctly when I have the problem..
