Re: 4L80E Line pressures

Mine is set very similar and has been successfully driving well for the past two years. I even did some doodling with pressure values in the low speed and load region to make it feel like a stock cushy box ;) I've ran it on slicks a few weekends a year and works really well. The "load" sho...

Temperature vs. Line Pressure Adjustments

Has anyone successfully used this feature? I want to command higher line pressure when the transmission is cold and have it ramp down once at operating temp. I tried changing the values from zero to either a positive or negative interger. After making changes I see some really strange PC PWM% values...

GPIO, VSS and PC ideas

Hi, I just wanted to share some of my GPIO build that may be useful. Currently the system is stable and working well in my daily driver thanks to Lance and other forum member's help! 1) Dealing with the VSS signal has given us all fits in one form or another. My solution was to simply use a factory ...

Re: Pressure Control is not responding to Load (GPIO 4L80E)

SUCCESS! Looks like it works well now Lance! I took your advice and created a new project using the 5.099zviii firmware and the accompanying .ini you posted. Drove the car for about an hour with no issues and was able to tweak the tune while staying connected :) I'll drive it for the next week to wo...

Re: Pressure Control is not responding to Load (GPIO 4L80E)

Hi Lance, I ran a Comm Debug Log with current 5.099zi firmware and matching ini. I didn't get a chance to try the 5.099ziii yet, maybe this weekend. Attached is the log file and the Project folder in zip format. Strangely the TS stayed connected for the longest it ever has, maybe just a coincidence ...

Re: Pressure Control is not responding to Load (GPIO 4L80E)

5.099zi_project_3_23_2015.msq Rob, Also, if you were willing to email me your project file for 5.099 (a zipped file is fine) I could try it here. Lance. Hi Lance, Yes, I'm attached directly to the GPIO board where the DB9 connector would normally go (see attached pic of my GPIO). I will try to crea...

Re: Pressure Control is not responding to Load (GPIO 4L80E)

Rob, I was looking deeper into this, and there was a small change to the fault tolerance settings for TS in the INI between 5.0xx and 4.146. The attached INI sets them back to where they were in 4.146. I don't know if this will help you, but at least it might eliminate one possibility. GPIO_MShift_...

Re: Pressure Control is not responding to Load (GPIO 4L80E)

Rob, In the meantime, if you were willing to try 4.146 and report back here, to eliminate any possible hardware issues, that would be helpful. Lance. Lance, I went back to 4.146 code and have no errors loading and logging, just has the line pressure issue. When I load 5.099y code, no errors loading...

Re: Pressure Control is not responding to Load (GPIO 4L80E)

Lance, I was able to get a short datalog before MS went offline (attached). It seems pretty repeatable, even though doesn't make sense to me. If I go out and start car without laptop connected, it will hang in 1st gear. I then come to a stop, shift into N or P and back into 4th (drive) and it shifts...

Re: Pressure Control is not responding to Load (GPIO 4L80E)

Hi Lance, something weird is going on now. I tried data logging while driving and it would loose connection and lock up the MS unit. I'd have to pull over and restart, then it would seem to randomly lock up even with laptop disconnected. Any ideas what it might be? I didn't have this happen with 4.1...
