4l80e tcc throttle close cax

[TrendSetter]

Hi,
I have seen other threads where Taz mentions having the addresses for the 4l80e tcc lockup tables and was wondering if there is any plan to release a cax for these?
I am building my harness now and would prefer to run the 4l80 wiring but would like the lockup on closed throttle.
I'm using cos5 for the 12212156 os.
Thanks

Post your tune when you are ready.

I could use this fix as well. My TCC is repeatedly locking/unlocking if cruising at around 20% throttle. TCC tables are basically stock 80E tables.

[Lextech]

Hhmmm, I'm having laptop, .ctz issues. Let me get this sorted out.

Jeff

[Lextech]

Hey Drx. Try this out.

[DrX]

Got it. Thanks.

[TrendSetter]

hi,
could you apply the fix to my tune please?

Would really appreciate if you could modify my tune Jeff. Its a pain with a high stall triple disk converter locking in and out thanks.

Hi Dil,
I don't have the parameters for that Operating System. If you tell me what year it is based on and I can try to see if I can figure it out.

Jeff

[Lextech]

Ok, I looked in the COS tutorial and saw that it is based on the 12579405 Operating System. I added the parameters for that. Here is your calibration.

Jeff

[PSI]

That was quick , thanks Jeff, much appreciated . I must be really dumb or I've had a long day at work, but I cant find the parameters in the uploaded tune . I looked under trans and tcc tables couldnt find anything . Could you please point me in the right direction.

[Lextech]

You won't find the parameters by viewing your calibration. They have been changed but won't appear without the appropriate .cax files installed into your software.

Jeff

Hey Lextech, Could you upload the cax files for this? If not could you apply this to my tune?

[Lextech]

Hhmmm. Try this. I lowered the MPH a bit.

Just a heads up, my truck kicks the TC out when i let off lightly as in going down an overpass. And when i run over 73mph. The DTC codes says cylinder missfires and cylinder#7 missfires. I have chased everything electronic finally put a stethoscope to it at #7, oh my heavens!!! Ive never heard such a noise from a "good" running motor. Gotta get in there asap. Check your misfires??

Lifter/valvetrain noise...?

Lifter/valvetrain noise...?

Tinbender is old school, he may have used a stethoscope to come to that conclusion. Pretty sure his motor is stock.

[joecar]

Steth is fine... I'm wondering if it's just valvetrain, or if it's more severe.

[Tinbender59]

sorry i wasn't notified of the responses, yes, I used a Stethoscope, I have had the valve cover off, couldn't see anything obvious. I hope to get the G6 out of the shop tomorrow. (bad fuel tank vent valve, leaking oil sender took out the starter, starter took out the battery "weak anyway") lol Are we having fun yet??? anyway?? The truck is going in for exploratory surgery Monday or Tuesday, worst case - broken piston, not burning oil?? best case - collapsed lifter, probable issue - pitted camshaft. my machinist thinks this is the problem claims to have seen a lot of them lately??, it does sound like a stinking diesel at idle!!! gurrrr I've got $13000 invested, not quitting now.


look at this https://www.youtube.com/watch?v=ux84a6SJAc0

[Supercharged111]

My 454 did that. Got the truck like that and didn't even know it, the belt sqeaks were louder than the ticking. When I was addressing the belt squeak I heard the tick so I just ordered a cam and lifters without opening anything. I was right. I'm not sure that the 8.1 was prone to this as well? If so, you can run a GenVI cam if you get the plate so you're not subject to the terrible aftermarket of 8.1 cams.

[Tinbender59]

Long story short found the rocker arms wore out where the ball sets, making a popping sound when you move the ball. Second Long story short expert wasn't going to tell me that unless I bought his rockers. But he did mention if I put a larger than stock cam in I would wear them out , so I went looking. Also found camshaft had gald marks on it, check the rollers in the lifters, all three that I checked, the roller bearings had rough spots in them. I guess it isa blessing in disguise that I caught it before it destroyed the motor. I'll be Going back stock with everything. my research shows if I put a bigger cam in, I'll have to put in roller rockers, next will be springs, then headers, then??? where does it end. Ill just stay stock, it's a farm truck. Besides $600 repair bill beats $1600+++++??

[Tinbender59]

P. S. Sorry for hijacking your post

[joecar]

Good that you found it now.

[Tinbender59]

Thank you

I never got around to looking into the issue the project got put on hold , I think it was a ECM issue or the tune file was corrupt because commanded timing kept going to 60 degrees.

[PSI]

Now I have a different project going was wondering if somebody still provides a service to have the tcc locked at 0% tps and also have the ability to hold first gear in manual low and not upshift to 2nd . Would be willing to pay a small fee as well just want to get it sorted . Its a 2000 ECM with 512 kb memory . It just sucks efilive doesn't do anything about it since both features are available on HP tuners. Thanks

Anyway we can get the CAX for this?

[nonnieselman]

Contact Lex Tech and he can help you.
Don't think anybody is gonna hand out a CAX they spent alot of time on.
