ZF 6HP26 TCM - Now Supported in 2.25 Beta

[turbotrana]

When I was younger I would have had it all sussed by now. Nowadays I just hang back with me babes and let everyone else suss it out for me.

Now where's Jet gone.

For now the ZF Definition is done, unless it is determined that we need to add something.

Compare function is top priority for Keith right now, so it should be done quickly.

Scanning functionality to follow.

Thanks Eric, I sent my request for the repetitive spark to be added and sent the file to Bill, so I dare say you should see that through shortly. Then hopefully that sparkmax will and my eboost correction will work nicely and track times will tumble!

Alternator output table Eric?

BUMP... just wondering is there an ETA from Keith when compare function is working?

^^^ Second That ^^^

[bugsy]

Bump
How is the scanner looking guys?

[JETURBO]

Two weeks ......

[Eric@HPTuners]

Two weeks ......

Never said that. Soon though..

[bugsy]

Two weeks ......

I was thinking that

I was hoping that!

Any way to prevent it from kicking down? I know you can avoid hitting the switch on the pedal, but sometimes you get abit excited and push abit too far?

[bugsy]

How is the compare function looking?

Have done a few slight changes to a box last night which responded well.

Any chance that that the beta has been dropped for hach3ca ?
It will read the calibration only file but then has an error when trying to access the trans file
I will try the complete read tomorrow and see if that works

Gents,
I've thrown together an excel workbook setup to convert either-

Trans Output Shaft Speed (OSS) to Road Speed and Engine RPM
Road Speed to OSS and Engine RPM
Engine RPM to OSS and Road Speed
Data from Shift Pattern table in the Tune (Values only no Tables Axis)

In order for the sheet calculate the values you need to enter the following

Diff Ratio (2.73)
Wheel Dia (in Inches)
Revs/KM (Most online calculators and some manufacturers will tell you this)

All yellow cells are input cells, all green cells are results and contain formulas so dont fiddle with them.

How to use-
Enter your Diff Ratio

Wheel Dia and Rev's Km.

Open the shift pattern table you wish to review/modify,

Copy the values from the shift pattern table,

Paste into the Yellow Cells in the OSS RPM Table the sheet will calculate the road speed and Engine RPM for the given set of values.

You can then use the Desired Shift Speed (KMH) or Engine RPM Yellow input cells to modify the Pattern to your desired outcome and copy the Green Cells from the OSS RPM Table to the tune.

The idea behind the sheet is to assist us all in understanding the 52 shift pattern tables and how they relate to the way the trans performs.

Please keep in mind this is a only a quickly thrown together sheet for my own benefit and in sharing I take no liability for damage/death/plague/pestilence etc etc USE AT YOUR OWN RISK.

Please also keep in mind there is a set of min/mx OSS RPM values that will alter the final shift speed.(Located on the Auto Shift Speed Table under RPM Shift Limits)

Please feel free to review the sheet, point out any flaws and offer suggestions.

REMEMBER YELLOW CELLS ARE INPUT AND CAN BE EDITED GREEN CELLS CANNOT

Hi Guys,

Did the full read today and I can access the trans file now.
Has anyone else had an issue with the BF series calibration read only?

[bugsy]

hiddeous you legend

[DarrylC]

hiddeous,
Brilliant, I may even now be able to work out how to fix that stay in second gear when car comes to rest. Brilliant

[hiddeous]

Start with you 2->1 downshift OSS speeds and 2->1 downshift RPM limits

[mycomputeratesme]

Awesome Hideous well done
