Default Final drive change on 6MT - coding required? - 03-05-2019, 04:16 PM

Hello all. I'm currently running JB4 with BEF on the stock turbo but I'm upgrading to the speedtech 7670 kit this week. I'm also installing a helical LSD with a 2.81 final drive. Are there any changes required when doing this with a 6MT? The transmission folder in the 98G0B xdf does not have "rear axle ratio" or any other gear ratio tables defined when I open it in Tunerpro.

Thanks in advance.

FYI all the 2.81 final drive change does not seem to be causing any issues.

Default Boost target - 05-05-2019, 11:39 AM

Hi Terry,
Seem that I'm like 2psi under target. Should I just increase ff? How is everything looking. Using 40 meth add should target 19 or 20psi?

Thanks

Duty bias should be learning up. You can add 10 across the board to speed that up though.
