6th getting locked out at high speed!
At 130+mph (210+km/h), ~3600rpm, 6th is locked out in all shift modes preventing any high speed cruising. It will downshift 6>5 at 130mph regardles of throttle postion (pedal/actual) or load.
Nothing in the E38/T43 tunes makes any difference. I've tried changing all the relavent tables/settings, including blocking 5th over 100mph in all modes!
Anyone else had this problem?
Anyone tried 6th over 130mph/210km/h?
Is there another else I can try to maintain 6th over 130?
Is this another BCM controlled parameter (like original speed limiter)?
I have been trying to get the Middle East settings/cals (ME speed limiter at 205mph), but can't get HoldenCrazy.com any more!
I don't get on the Autobahns as often as I'd like, but this really spoils the experience!

From what I can understand, HPT has the abiliity to over come this.
Also, T43 "Hot Shift Speeds" {D1005} and {D1006} headings wrong way round!!!!!!
Any help grately appreciated.
