    Cam Source

    in Engine Tuning (AUS)

    Posted

    thanks for the replies

    I was aiming at trying to find out how to get it into part throttle mode or at least where it comes from, as when in Max Power mode the desired cam angle (VCT TRG INT)  is reaching the cam angles specified by auF16501 (VCT Angle) and limited by auF16610 (VCT Angle Max Retard) when at steady driving, until the cruise control is activated. (The cam is achieving the desired position and then moves a lot)

    When I activate cruise control, I get a jump of sometimes over 20 degrees in cam timing, while my wife's car is already using the larger retard numbers

    The screen shot shows the change when cruise control is activated (just after the blue position line), the torque source goes to 14, the cam source goes to 2 and the cam moves just over 20 degrees as though it is ignoring auF16610

     

    My car = HAER1UB

    Her car = HAEE4TY

    p.s auF16610 has the name VCT Angle (RPM - rpm, Load - LOAD) but in the table the description is Maximum allowed Overlap Angle based on RPM and Throttle Position. which I think maybe a mistake.

    Hi Rolls

    I've read through it again and unless I'm missing it, there is really nothing there that indicates where the source originates from.

    Is it possible for me to change my tune file strategy to a different one without more credits (adding my VIN to the new one) to find a strategy that does not do it and then do a compare the two to see what is different, to find a possible scaler/table etc?

    Does anyone know where or what "Cam Source" comes from?
    My Sprint calibration Cam Source drops into "Maximum Power mode" as soon as the throttle is applied, even in neutral, my wife's FG G6ET does not act like this.

    Unfortunately Matt has moved on to another job so datalogger development will likely be halted until we can afford more employees. We will continue to fix bugs however there won't be any new major features in the short term. 

    thank you for the honest reply

    I did a bit of search and I reckon the following scalars might reset the learned data

     

    ZF02859 Switch for activation of the EEPROM data handling EE_SPIEGEL 0=OFF, 1=ONLY START, 2=ON

    Stock value is 2. I set it to 0, flashed the TCM and adapts had returned to 0. I started the car and adapts stayed at 0. I then returned ZF02859 to 2, flashed the TCM, started the car and adapts stayed at 0. .

     

     

    This cleared my Adaptions as well, FG MK2

     

    Thank you very much

    One that's worth a shot is flashing a BF strategy into an FG or vice versa then putting the original os back. In most modern Fords they reset the KAM when that happens. 

    No chance of an issue by just flashing it in? Obviously not going to try to use it to run the car

    Yep so check these values. Then try and "reset" them. Then datalog again and they should be back to 0 before you start the car, then they will slowly learn back to what they were before. There are various adders for how fast it can learn forwards and backwards. It doesnt really make sense for a clutch to get better, hence why when you put a new box in they dont like to unlearn the wear. I'm sure there are some PID gains you could adjust to speed up how fast it learns in the reverse direction.

    I set ZF03182 to 0, flashed it, tuned on data logger and learned values were still there, I reset ZF03182 to 1 reflashed it again, checked with logger again and still the same values remaimed.

    If someone in SA loans me a ZF falcon with high kms and a box that is heavily worn for a week I will figure it out. 

    Until then we need sometime in the community to datalog the adaption values that hjtrbo found, try the various suggestions and report back. 

    I've never tried but it might be possible for us to directly write to the dmrs used for adaption. I dislodge they will be overwritten by kam on startup though. 

    is there anything you want me to try?

    No, it's been covered before, resets pcm stuff. From memory idle learn values and fuel trims??? If you search you'll find the thread where Roland give us the run down. 

     

    The ZF adapt reset is a bit of a mystery. Some say the procedure available on this forum works, others say it doesn't. There is some bench flash software starting to make its way out to the public which is used for OS swaps. If that writes to the adapt area and resets it back to 0 would be awesome. No idea if it does. 

    Which numbers is Roland talking about that you found?

    These ones?
