HOWTO: Disable or reset ZF 6 speed long term adaptive learning.

[Roland@pcmtec 1,508]

If you have a freshly rebuilt box with extra clutch packs you will find that the car bangs into gears and is generally horrible to drive. This is as the adaptive learning has to unlearn the clutch wear. It takes approximately ~1500km of light cruising to achieve this. We believe the learning algorithm learns forward (eg learns worn clutches) much faster than it learns in reverse, this is as logically a clutch can't become "unworn" so the algorithm probably was not programmed with this in mind.

To disable the long term learning algorithm set ZF03182 to 0

To reset the long term learning set this to 0, start the car and put it in gear. Turn the vehicle off then set the variable back to 1.

It is reported that it takes less than 100km for the vehicle to learn the clutch wear on a standard box with 150,000kms if this is done. We have another workshop trialling this out on some new boxes shortly to give us some more feedback on how accurate the learning period is and how well this works on a high hp (800hp) build with lots of extra clutch packs.

Update:

This is not 100% confirmed as working on modified boxes. We have had a report that it does indeed work on a standard box however. Most likely this is as there is only a certain range it can learn as one workshop trialled this on a heavily modified box and found they still had to pull a lot of pressure out of the tune for it to stop banging into gears.

Can this be done to a standard box also? And would there be any benefit of doing this to a standard transmission?

[Roland@pcmtec 1,508]

It would drive terribly if you disabled it on a box that had learnt the clutch wear.,

Hi Roland, 

Can I change this value in the professional version or do I need the workshop version?

[Roland@pcmtec 1,508]

Workshop edition is required for that one. We have a special on until the end of the month or the first 20 customer 50% off if you want to upgrade!

Just a question,

What does the "reset adaptive" do then when ticked if flashing a tune?

When writing the PCM it triggers a "hard reset" which clears the long term fuel trims and various other learnt values like idle airflow adders etc.

Any chance it could be added to the professional version? Resetting the tcm adaptations is important when moving the zf mechatronics unit (which includes the TCM) from one box to another as the clutch wear will not be the same between the boxes. Interestingly the BMW guys reguarly reset the  zf adaptions however there seems to be no affordable way to do it with the falcons. 

[Roland@pcmtec 1,508]

We are the only company who has mapped these parameters to date, so we need to recoup on our investment which is why we don't put everything in the professional version. There needs to be an incentive for people to pay full price.

I understand, but I only want the reset function as a service function, i have no interest in any of the zf tuning features of the workshop version. After calling a few transmission places you could actually release a tailored "zf adaptation reset" tool and sell this to the service market rather than just tuners. However this would need to under cut ford's IDS software in cost per use.

There would be no return on investment for us to build such a tool unfortunately. Forscan, IDS, FDRS etc all do these tasks much better than we ever will and support thousands of cars for a tiny price. The Falcon ZF is the only TCM that Ford never released a tool for.

To build, test, QA and release a product like that (which would only support a now extinct model of car, the Falcon) would end up costing us close to $100k in development, not only that but we would lose 3 months of development time on our flagship products (the multi tune etc). We would sell maybe 100 copies of the software and I doubt anyone would pay more than $300 for it.

There are a lot of things we would like to do, but we have to say no to about 90% of them as we would end up building 50 tools poorly instead of 1 extremely well.

You can see why the high end scantools cost thousands of dollars a year in subscription fees, it is a huge amount of work to build and maintain even simple products. So if not many people use them, you have to charge a lot of money to make it anything other than a money losing exercise. Where as with something like a tuning product that people use daily and are willing to spend $150-$500 per car in licensing fees, you can suddenly dedicate several full time staff to polishing and constantly improving the tools for multiple years.

@Blackxr6t If you or anyone else needs it done you can always ask on the forum and there might be someone local to you with a workshop version that will do it for you. That way you'd only have to pay the cost of the credits for re-licensing and possibly some beer money.

 

Am I on the right track here @Roland@pcmtec?

Ford's IDS software cannot reset the adaptive tables in the ZF. Whoever is saying it can is misleading and is misinformed.

Yeah there seems to some confusion out there about resetting the PCM adaptations also resetting the TCM at the same time. I have just cconceded that the transmission will need replacing and have found one with matching hardware and software tcm codes.
