ZF 6HP26 TCM - Now Supported in 2.25 Beta

[45T-XR]

I haven't had a chance to play around with the shift timing etc. But Eric did you have chance to edit those ones I was telling you about in the second half of the shift pattern 27. I'm told the x axis across the top should be
1>2, 2>3, 3>4, 4>5, 5>6 (which is correct) then i think it should be 2>1, 3>2, 4>3, 5>4, 6>5 Can anyone confirm? I think SCT was incorrect also.

Update, I fixed it already

You go alright ay. Thanks mate

Just found out that the compare function is mostly working with 2.25.925 (this mornings download)

Don't try the "Copy over Difference" on that transmission section, generates a bug report and then crashes but at least you know what to change!

And it shows "Hidden Parameters-> Ford" that are different but am not sure how to access them!

Brilliant.

And of course my beta access has expired..... Dammit

Wow! pretty stoked with progress gents. Well done to the team at HP

Gone as far as I can go with my tune untill the scanner upgrade, was just wondering if the scanner is progressing as expected?

Thanks

+1 it may have been a late start to the ZF tuning bandwagon, but you guys have pulled out all the stops.

but you guys have pulled out all the stops.

If you relied on gals to get things done we would still be driving the horse and buggy.

Awesome job on getting the compare going
Any chance of the copy section next??

[stk235]

Thanks a lot guys, bloody awesome you have added support for the ZF stuff, and so fast too!

Does anyone know the what the "Downshift Inhibit" function does (under Transmission -> General)?

I can guess that the "Max RPM: tries to avoid shifting down if the revs are above this threshold but the "Min RPM" function does not make much sense as my car is set to 2200rpm but when cruising you are always below 2100rpm and it certainly changes down without much "inhibit".

Thanks in advance.

BTW. Seems like the "Copy over Difference" has been split into two functions and a quick check is working. Awesome

Post file and I'll have a look.

Eric,
Attached is the tune file I read for Bill so that the licensing issue could be resolved. Standard transmission tune.

OK, as suspected, those parameters may not even apply. They are in the ECM, leftover from the other transmission. That is not part of the TCM parameters I added.

Eric, thank you for that, much appreciated. The ZF is a challenge for me but have found that "just" changing the shift tables completely transforms the cars driving characteristics. It is no wonder that tuners charge good money to tune one of these!

[bugsy]

Eric , What is the chance of getting minimum and maximum times in the trans area?
Ie: Ramp , upshift and downshift

Also does anyone have information about changing one table will effect others?
Second ramp shift time in auto shift properties tab has an effect on ramp time in the torque management tab?

Hopefully some of the guys that have tuned these boxes before would be kind enough to share some info so we avoid killing a trans.

Thanks Guys

I'll definitely take a look, and if I can find it, add it in.

Thanks Eric
How is the scanner coming along?

Keith is working on it.
