Maybe i can help share your work load with the 4L80E side of your programming? I know I have to use PWM on the pressure solenoid and i know which frequencies to use. Some code to start with getting me in the right direction for automatic shifting and how you use the map sensor in conjunction would be the biggest hurdle for me. It would be real nice for us to not have to use our toggle switches anymore lol. Maybe we can help each other out?

No offense, but I am not really interested in sharing the code Ive spent the last year developing at the moment.
the only real component i am working on lining out is the pressure control system. The basic shift pattern is pretty easy to figure out.I can help you out with that but the rest is confidential at least for now. PM me and we can talk more.

I realized it's been a while since I've posted an update so here goes.

The 4L60E/4L80E transmission controller is ready for the road. I have also been working on an alternative to TunerPro. Even Though I'm a fan, I was ultimately looking for a simpler interface which is what I have. Attached are screen shots of the interface program. It currently has "full" functionality minus some diag stuff I'm still putting together, a work in progress as always.

I can also put together controllers for GM FWD, Ford OD trans both 4 and 5 speeds and the Chrysler RWD's are soon to follow. When the TCU website is up I will post a link for interested parties. Thanks for looking.

If anyone is interested you can contact me via email or PM.

Neat.

Will you be releasing a TP definition? I'm thinking of the folks that have gotten used to Tunerpro but may not be comfortable learning new software.

**buddrow** · 01-20-2016

I already have an .adx for it, havent worked out the xdf yet. The software is meant to be easy to use so there isnt much of a learning curve such as you would have with TP. As far as veiwing and logging sensor data and whatnot, both TP and my Gui will do the job. If you look back a few pages om this thread you will find the adx i built.

34blazer, are you still looking for a replacement for the JTEC? I'm looking into the dodge stuff now days and could use a tester if you're interested just pm me.

"Any suggestions on what arduino to use?

Also need suggestions to drive the 4th gear, and TCC switches, and the EPC?"

Since the 46/47/48RE's only have a few inputs/outputs, you could use an UNO or even a Pro Mini or Nano. I use a MEGA which has twice the ram and almost 3 times the I/O of the aforementioned boards.

The EPC you refer to is the governor pressure solenoid which has an accompanying pressure sensor used for feedback to the tcm. On the 2003 or 2004 model 48RE Dodge used an electronic Throttle valve control on the diesel engines. The electro-mechanical TV control unit is prone to failure, pricey and mounted to bosses cast into the case so you have to use the 48RE case.

Anywho, I'll have the website up and going before long but be patient while I add product and tech info. Anyone interested or want more information feel free to pm me.Thanks for reading.
