I spent hours logging, tuning, logging, tunning etc and never got it just the way I wanted it. In just a few tries Dodgeboy_8HP made it perfect. Sometimes it pays to pay. ;>)

This was the best reply I have had on this forum. I now have a very effective tune. I was a bit of work to get it just right as I'm a fussy old fart but DB was able to set it up just the way I...

After trying for the last year to tune my own and even tried some of the big name tuners, I finally have the perfect tune thanks to Dodge Boy. I also wanted increased engine braking during...

Yes, did the ticket and had a response. HPT has now decided that those tables should not be allowed to be changed. The older software was a mistake. I'll start over on my tune. :(

Thanks for the response spoolboy. I have been playing with the shift map tables for a long time and have off throttle downshifts happening quite well but had to bump up the down shift OSS by quite a...

Same issue. Shift pattern mapping table (30000) and a few others are "read only"
Did the course, input the code did the refresh and re sync, re start laptop and refresh again. still nothing.
I was...

Once again I appear to have asked a question that no one knows, I'm good at that.
Let me ask this, what dictates downshifts at zero throttle?
If the 2>1 shift is set at 80 in the pattern tables,...

I'm slowly figuring out my mapping but have not figured out how to add more engine braking when going down a hill. When using cruise control it must do some engine braking to try to maintain speed...

No problem asking the questions, maybe someone else will see it and help both of us.
A tune will not solve this, its a system communications issue. The PCM needs to see a signal from ??? in order to...

I have talked to others who have gone other routs and think the SGA module was the easy solution.
Russell knows the hardware and software very well.
Lots of inputs and output through the PCS...

It is getting the brake signal through the SGA module as you have to have the brake pedal down in order to shift out of park.
The SGA (PCS) module has two CanBus channels so the Cummins is on one...

Did you ever figure out how to add more engine braking?

Yes, I would like more in tow mode which in my truck is Sport mode.

The Cummins ECU is sending some info to the TCM like RPM, TPS and tq.
I would love a bit of help with some of the basic ideas so I can learn this but I don't want to hijack this thread. Would you...

If your referring to the two files I had attached they are the stock files from my 2014 ram 1500 that I was offering as a starting point for TylerR to use. My swap is a Cummins 4 cylinder in front of...

That's a great idea james1595, here is my stock ram 1500 5.7 trans tune as a starting point.

I'm not sure you will get any help. I'm in the same boat and asked a lot of questions with little response. As soon as you mention you have a swap I think everyone thinks liability or something. I...

Its been a while since I last posted. Lots has been done to the truck. Upgraded to the Charger console shifter so I can use manual mode and I like the console shifter.
I have a pretty good shift map...

I suppose its more accurate to call it decel downshifting? Zero throttle when coming up to a stop light.
It does a strange "hunting" thing when getting down around 30 mph, feels like its maybe...

That helped and I made a few changes to get my upshift RPM a bit higher especially at light throttle so it was not always upshifting when moving slow around town. I still wish it would downshift...

Thank you Smxtmpr34, I would not want to write entire since its not running through the RAM ECU but through a PCS module but it will give me a starting point to make my shifts better. Does it...

I stuck a Cummins ISB170 in my 2014 Ram 1500. Its basically a common rail 4BT. The trans is receiving RPM, TPS and torque from the Cummins CAN bus.

I'm trying to build a trans tune for my abortion of a truck. I had to start with something to get me on the road for a holiday trip last week end ended up with this.

Now that I've been...

Rockhound, I sent you a PM

Can anyone recommend a tuner who may be able to help?
Our family holidays are coming up in a few weeks and were not going anywhere without this truck.
