i need to tinker with my HPT today ,,, where do I go in the software to adjust the kick down? anyone make a video on this?

Those are all in shift scheduling. Downshift MPH vs. TPS. For now, I would leave WOT tables alone and in the normal tables leave 100% alone.

 

Also make sure you tweak the upshift if you make big moves on the downshift. You don’t want to make the transmission hunt between gears.

what do you mean tweak upshift?

 

can i see your file?

Let me hop on the PC and post some screen shots. 
 

What I mean is if you change the downshift table up 5 MPH, you will also want to change the upshift table.

 

If at 25% throttle you command a downshift below 20 MPH in a given gear (and say it was 15 - that will make it downshift “easier”) if your upshift was 21 MPH that would make a fast downshift and shift right back up. I would bump the upshift up about the same amount, at least a few MPH.

 

I have mine set up to stay in a low gear for MPH. Mid range has a reasonable downshift without having to stab the throttle to the floor. I also adjusted downshift times, but beware that if you jump on it in the middle of a downshift it will always lag there so just keep that in mind. I also setup tow/haul to be more of a sport mode. I don’t tow. The reality is there isn’t a lot different between the two. I do leave more negative off throttle/low throttle driver demand in tow mode in case I do tow.
 

I keep my converter locked too, I don’t see what people dislike about it. I actually prefer that over having it flash up on me. I also did adjust my TCC apply pressure, so maybe that is why I don’t notice issues too.

 

If I don’t post back up by the end of the day, PM me to remind me. This PC does an update about every time I turn it on and I lose the network and it takes forever to restart. Windows 7 was great, 10 sucks lol

Here you go.

good info thank you!

 the tcc on these Torque converters might have issues being locked up all the time.  premature wear  on the clutch ,  i would like to install a zl1 converter, hopefully those are built tougher

I don’t lock it any more than stock, actually bumped the MPH in a few spots. I just don’t leave it unlocked in low gears, I find it annoying.
