The 12100 RV Edition module fits the ISC 8.3L and ISL 8.9L Cummins engine utilizing the CAPS fuel injection pump from 1998.5-2005. The AG Diesel RV Edition Module is designed for everyday use whether you are towing or just looking to save some money on fuel costs. We have been getting fantastic feedback from our customers regarding this module and ZERO issues.

The RV Edition module will increase your power 65HP over stock all while delivering fuel economy benefits of 1/2 to 1 mpg. They are dyno tested to a 40k load so we can ensure that you are towing safely. This module is self-adjusting based on load and will deliver up to 20% more power when needed.

And before you ask…no this does not flash your ECM! Instead we receive the data from the ECM and optimize the signal to the engine to improve both power and fuel efficiency. True Plug-and-Play connectivity means we aren’t going to ask you to cut and splice any wires. Just connect the module into your existing factory connectors.
