has anyone logged 6l80e pressures

[icicleboy]

oh no

bump.... is this beta ready?

No.

[icicleboy]

No.

eta?

[Bill@HPTuners]

Likely a few days but could be longer, we'd rather do it right than just slap something together so that it gets out quicker.

[Bill@HPTuners]

New beta up for those that requested it thus far.

[camaro1]

thanks,


i just changed the SHIFT PRESSURE DEFAULT to 147, and the new table MAX PRESSURE to 150

then did a couple wot shifts and noticed no change at all in shift feel, and in the scan tool the pressures still max out at 109.9??

Bill Can you set me up with the update.

Thanks

What is the status of this fix. I have seen a couple of posts that claim the Beta did not fix the pressure settings?

I have Beta 2.23.3567.30387 that I understand included the initial fix. Is there a new Beta that updates the fix?

[Dan Wendling]

Bump

Any luck with a fix? 2-3 shuttle shifting is becoming a problem with this box when aggressively tuned without the added pressure. Diffenately limiting the ability to tune correctly.

line pressure is still limited,, my car is now put away for winter, almost wondering if these handheld tuners have any better luck raising pressure, several of them say that they can raise the line pressure on the camaro 6l80e

try setting the max clutch pressure and others to something like 400 psi (ie. double what you want).

PCS1 is the main line pressure that feeds the individual clutch solenoids, it is controlled by the base shift pressure tables. Again these values might be calibrated to double what they show in the scanner. The clutch solenoids are downstream from the main pressure reg so even if the command a higher number they don't actually get the pressure unless the base line pressure is increased.

In many cases these maximums are calibrated after the pressure regular gain (approx 2.0) so pressures in the cal are double what you see in the scanner.

funny u say that i pulled a Superchips CORTEX tune(awhile back months ago)
the table that is 275.6 from the factory(maximum line pressure) is 400 PSI...

[04blackgmc]

btw so ur telling me the max line pressure vs gear Vs RPM changing that does nothing?

Any updates?

Yeah, not looking to ressurrect this from the dead, but I am also not looking to make new threads when this has covered alot. Will this ever get "Fixed"? I'm trying to tackle some flaring issues and I don't know what numbers are real, and what isn't. Kind of defeating the purpose of taking logs, if the logs aren't helpful. To be fair, this 6l90 has been a nightmare to get dialed in. Some people make it seem so easy but for me, its either shifting like a lightswitch on the 2-3, like .08s no matter the engine load, or If I load the factory tune, flaring on the 2-3 and 3-4. Fast adapts have been performed. I can definitely figure it out and get it tuned nicely but I am just trying to gauge what the pressure readings really mean.
