EFI Live T43 Shift Time tune strategy

[mowton]

mowton,

Do you know if the other tool happens to have the ability to show what the adaptive cells are doing? I have played with the LS1 PCM and tried to out think what it's doing by watching and logging the trans data, but only kinda got it figured out. Some of the things that I wished I could see were how the torque channel was calculated (it appears that this is what had a significant impact on the shifts) and what the TAP cells were. Thus you could start off with the adaptive cells at zero and watch them move based on the tune in the PCM.

For what it's worth, similar questions have been raised regarding the Allison TCM's as well and the ability to try and "figure them out". So far, not too many people seem to know ... or are sharing ...

turbo_bu et al,

I haven't been able to work on this but what I can tell you (and anyone else interested) is that when you tune via the EFILive tuning software (Normal up-shift time), and pull the file with the "other" software, only the Normal Upshift Timing tables were changed, all others (up-shift special, down shift, down shift special) remain stock. So per above, I quess WYSIWYG :(, unless I am missing something?

I have scanned the normal TCC parameters, shift times etc. I will be in the shop on Friday and hook up to a car to see the exact parameters in the scan library.

EFILive can scan these PID's in the Allison trans - maybe they are available in the T43 but just not included...

Paul, Ross, are these available in T43?

And there is also a PID on some trans controllers that shows values from adapt cells. Like mowton mentioned, it would be great to get visibility into T43 adapt/learning so you knew whether you were tuning a fully learned trans, or a yet to complete learn cycle.

ADAPTCELL [1] Adaptive Shift Cell Number (Count)

Incidentally the torque number is calculated in the ECM based on an MBT map that GM sets up on the dyno. It gets transmitted to the trans on the CAN.

FWIW...

Hi Ed,

AFAIK the EFILive tunetool is WYSIWYG except where noted (like the VVE tables).

Hi Ed,

Joe, Hi back at you....based on my expereince above, have to agree with you. Wonder why that is?....oh well there are pluses and minues for both software packages so using both gives you the best of both worlds.

Have a great weekend

gmh308,

Those PID's appear to only be in the 6 speed Allison ... not the 5 speed.

Do we know if something like those are available for any of the other GM transmissions? Example 4L80E in the LS1 PCM? Maybe just the newer TCM's have those for viewing?

[joecar]

No, the 4L80E/4L60E LS1 pids only go up to TSTATE12.

Turbo_bu,

Here are the Supported PIDS for a 2007 A6 Corvette.........

Anymore info on this?

[slowhawk]

I pretty much get what your saying, There is a serious lack of tuning adjustments with this software for T43 transmissions.
I completely agree. My 11 Camaro has no means to do anything with TM.Frigging thing pulls out stupid amounts of timing on shifts.You can band aid it with tuning but not hit the spots you need to. Add a high stall converter and it turns into complete crap.

Hopefully SOON this will be adressed.

I feel your pain slowhawk, I got a 2010 GMC Sierra with Blower and Built 2500 stall 6l80e and this thing is giving me headaches. I too feel that there aren't enough tuning adjustments for the T43. There isn't even a base shift timing table in the software that I can find. Only Input torque modifiers, and those have to go off of a base timing I would figure. I've been messing with this transmission for a month now and it still isn't right. I'm so sick of intermittent shift flare, slow shifts, bang shifts, DELAYED bang shifts. I'm convinced the stall is messing with the load tables just not positive on how to overcome that. If I could see Base Shift Timing tables at the very least, I might get somewhere faster.
So amen to better T43 tuning adjustments SOOOOON!
