Part # 12200 -  AG Diesel RV Power Module ISL 8.9L / L9 Common Rail (2010-2019)


  • 2010-2019 Cummins ISC 8.3L
  • 2010-2019 Cummins ISL 8.9L / L9


The 12200 Performance Module fits 8.3L ISC, 8.9L ISL & L9 engines. This diesel performance module is designed for fuel economy with up to 30% increase in hp and fuel savings up to 10%-20%. This module differs from the other AG Diesel modules in that it plugs into the fuel injector harness instead of the fuel pressure sensor. This allows the module to make more precise and cleaner power to be compatible with the exhaust emissions systems. This module also features Bluetooth to change power levels! The Bluetooth feature is compatible with iPhone5 & newer, Android 7.0 & newer and Samsung S7 & newer. It has approximately a 30 foot range so most will be able to make changes from the seat of the coach.
This module does not flash or connect directly to your ECM. It plugs into the engine harness and intercepts signals going back and forth between the fuel injectors and the ECM. It uses factory spec connectors and does not require any splicing or modifications to your engine harness.

I have a 2020 Entegra Anthem with a Cummins ISL and digital dash. I am interested in a power increase and better mileage. Based on your description, it sounds like the AG diesel power module meets my needs, and would work with no need for user interface. What other benefits/advantages are achieved with the Big Boss Performance Tuner other than a display of engine parameters? ( Tom Luke, 07/19/2020 )
The benefits to the PDI Big Boss Tuner is that it is able to change numerous fuel and air parameters to achieve its gains, whereas the AG Diesel model is limited to just making changes to fuel injector duration. Both will achieve similar power gains, however, the Big Boss Tuner is more likely to net you some fuel mileage increase. ( Support )
