Default DBW goodness!

Ah. Had the pleasure of having Ty tune my DWB values. Soooo much better, smoother and all around more enjoyable to drive.

Granted I have a 4eat, so its a little more difficult to get good numbers into it that the tranny will like, but Ty hit the nail on the head.

Tranny doesn't automaticly shift from 4th to 2nd when applying more throttle. Nice and easy transition from 4th to 3rd which never happened with stock dbw.

Thanks Ty for getting me all set up.

Ty, what did you do to prevent the strange shifting? Or is it just me who has sees this as a problem. hahaha

Well I guess I never shifted directly into 2nd, but for me it's shifts earlier and stays in 2nd longer. Which to many isn't a bad thing. But from a MPG perspective, Meh.

So far, it's just you. I need someone local with a 4EAT to spend a bunch of time logging things for me to try to figure out what's going on with the way the tranny and DBW interact. It seems to work, so far, for everyone other than you but you know me, I always like to know exactly why things are happening.

I can log for you if you want. i got tactrix 2.0 with sd logging working.

mind does tend to stay is 2nd a little longer, but its not too bad. when i tried the linear(10/10, 20/20, etc) it would hold 4k in ever gear before shift.

Nah, I want to be in the car to feel what's going on and to be able to make experiments up as a I go along.

Maybe I'm doing it wrong? Care to send me a bin file to read?

I have had similar tuning issues on 2009 FXT. The auto situation was fixed and seems to be driving better. I believe it is a factory mapping issue, and PDX tuning seems to have it figured out.

My max RT Value I believe was exactly the same as in your writeup, but I tried switching RT Table numbers and the Throttle Plate Opening A numbers around to try and get the same effect, and hopefully leave the transmission shift points unchanged, but I got nothing.

Other thing is that all the cars so far that report good results whether it be subyroo or kewl, is that they are all 06+. There is a definite possibility that the TCU tables or the way it does things have changed from 05.

I reformatted my hard drive so I can't say for sure, but I'll pull a ROM out later and confirm it.

I just noticed the same thing you did about the relative years. The 05 ROM is entirely different than the 06+ ROM. It's likely the difference in your experience stems from that.

Considering that the RT Table and the Throttle Plate Opening table look so different from 05 and up, I wouldn't be surprised that the transmission feels better simply from the fact that the Accel Pedal % ->RT -> Throttle Plate opening is now consistent and no longer link that's dependent on RPMs.

If I remember correctly the 06 tables have more cells, but beyond that they were not a consistent link between accel pedal and throttle plate opening, but were dependent on RPM so even if the TCU was the same, the TCU would not feel as consistent just because of that alone.

There's a huge difference in the number and kind of tables (overall, not just in the DBW system) between 05 and 06. That strongly suggests behind-the-scenes logic changes as well.
