    I think I'm going to try flashing a stock ford file back to it. I'm kinda of scared about bricking it, but to her a subscription to download a stock ford file and flash it back with the Ford tool is...

    No none of it works for me even on the latest beta. I recommend you put in a support ticket request with hp tuners, maybe if we can get enough people to complain about it we can get some things...

    I tried this table many times, and it has not effect for me. The only way you can decrease the torque reduction on the 8L90, is work around it with the min spark table in the ECM. I suggest opening a...

    It's my suspicion that there is a limiter table that inhibits TC lookup if it is past a certain slip threshold. I think this is done for protection maybe. I have a support ticket open with HP Tuners...

    I've never noticed any change or difference when I change these tables. A lot of people I see just increasing the MIN timing table which puts a cap on how much timing the ecm can pull during upshift...
  6. Are you saying you think I am correct in thinking...

    Are you saying you think I am correct in thinking that HP tuners messed up defining this table and confused EQ ratio with lambda and that's why it goes against the normal theory of richer = faster...

    Thanks everyone for the info. That's interesting that the calibration is done by each design team. In some way that kind of makes a little sense so they can find tune things for their customer base...

    I set my TCC apply/release to align with the part throttle downshift table, so I set it to where when coasting down (when TPS is 0%) and the transmission is downshifting, it will leave the torque...

    Can you elaborate a little more? Are you saying there is a way to make the TCM do it with what we have available? I'm pretty sure I remember the converter locking at WOT back when I was stock.

    Not to discourage you, but no one else seems to be bothered by the slop in the drivetrain including GM, because I think they could have programmed it completely out.

    To me though it is way way...

    Seems like its going to take some high end racing teams to push HP Tuners to uncover the right tables. The Duramax guys got EFI Live to do it for the Allison TCMs they just need to realize the wasted...

    That is true on the 2017 graph, except for very cold starts where it goes richer than it does since stock PE is in the 1.15+ EQ range.

    But there are other years where the stock calibrations have...

    Yes I believe they were at least the length of a sled pull and a 1/4 mile run. What about trying to hack the bi-directional function to come on as needed I don't see any other limiters when it is...

    I believe you would burn up the solenoid if you just straight up ground it, I think you would need to build a stand alone PWM driver. This was the case with the Allison TCC in the duramax you would...

    Haha thank you Parish, I have messed with all of those parameters too many times and notice absolutely no difference. And good idea about trying to use bi-directional controls, at least we can use...

    Thanks Taz, so I wasn't just talking about a comparison between them but a comparison between the years.

    What I am specifically talking about is the PE/COT timing correction table:

    I looked at your tune but I don't see anything out of ordinary. Can you get a log to see how much the throttle is opening? I have had a weird limiter that limits throttle (predicted torque) to like...

    Thats interesting, I didn't realize the values in that table was a limit value, I thought it was the actual amount of torque reduction so a lower number would be less but I guess not.

    I was...

    Yeah it dosent make sense that its only for thoes specific solenoids, but how are you flashing the solenoid data? Do you have a TIS subscription? Or is there another way to do it?
