HPT 99-03 4R100 7.3 TUNING

Finally a solution for running the 4R100 transmission with a Cummins!

For years anyone wanting to swap a 7.3 truck to a Cummins had to use an aftermarket stand alone controller unit, though they work well they lack availability of tuning options.....you had to sort it out and do it yourself. With our tuning now available you can swap a 7.3 truck ( other controllers will be coming soon ) this allows your truck to function as it was intended and all factory feature work properly ( OD button )

We have been testing this on one of our shop trucks a 1999 7.3 running a Cummins 12V with some fuel and turbo upgrades, stock trans with low stall swap converter. You will need to retain a few of the 7.3 engine sensors, oil pressure, coolant temp, map and tach signal. We use Tach Helper for that. You will also need your stock 7.3 APPS pedal.
