Any talk about SOTF Tuning for 03-05 Cummins anytime soon??

He means comparable to EFI Live's CSP5 OS modification.
Tune switching without a re flash. I for one would love to see live data tuning in RAM for dyno pulls IE, Rail, pulse, main/pilot timing, shift points. Then when you had a table created that achieved the result you save it to ROM for it to be permanent on a re flash.
I think he means switch on the fly tuning, like a csp5 switch equivalent.
Look up Optimal welding tunes. hes out of Canada and he sells a SOTF kit for the 03-05 trucks only issues is you have to use his tuning. Im thinking about getting it and then seeing if i can put my tunes on it if i dont like his. But its money wasted if i can not.

Just do the SOTF yourself if you don?t want to waste the money

Anyone can make it work with what?s available in HP Tuners, all it requires is a little ingenuity
If a redneck Alberta welder can figure it out, so can anyone else
yea i am no where near that good i only play with it a little here and there with help from a buddy who is a tuner. been just learning at my own pace.

You just need to figure out how/what to tie a SOTF switch in with to make it change which air density table you are running on, each air density table is its own ?tune level?
I would think that is possible. I know for the CM2200 ECU, there were 5 different air density tables for the main/pre/post injection events. Just zero out the table for the air density. As Jim said, the trick would be finding out the resistivity range of the air density sensor, and getting a radial dial resistor that matches it.
2019 CCSB Bighorn - Excited HP Tuners finally supported Cummins CM2350&2450 platforms
I was just tinkering with this and using Jims VP tune on a switch so I could try a few different things for testing. But I didn?t get much data before my transfer case decided it was time for a rebuild. (I?m clearly getting better MPG though).
Not sure what year the OP is but the 03 and early 04 you only have two options for the main tables. Transient and low air density. You can get the desired result of having multiple tunes but its not as ideal as having full control of all the tables like other years.
But you can tinker with other tables like Baro limiters A/B and correction tables. Even IAT.
03/04 there is a dual function inlet air temp/baro sensor on your air filter intake pipe. With a switch and some resistors you can tinker.
