A project involving a Cummins 6.7 swap into a Ford F350 necessitates the use of Live EFI for engine control, security removal, and delete tuning. The project utilizes a low-mileage 2010 Cummins 6.7 engine, initially believed to be a 2009 model requiring a Cm2100 Ecm. However, QuickServe data indicates the engine is a 2010 model, requiring a CM2200 ECM. A CM2100 ECM from a 2008 model was purchased prior to this discovery, raising compatibility concerns, particularly with the fuel injectors which have different part numbers between the 2008 and 2010 engines.
CM2100 vs. CM2200: Transmission Control Implications
The choice between using the existing CM2100 or upgrading to the correct CM2200 ECM significantly impacts the transmission control system for the desired 68RFE transmission. In 2008 models equipped with the CM2100, the 68RFE is controlled by a dedicated Powertrain Control Module (PCM). Conversely, 2010 models with the CM2200 integrate transmission control directly into the Cummins ECM, eliminating the need for a separate PCM. This difference presents two distinct options:
Option 1: Utilizing the CM2100 ECM
This option involves using a CM2100 wiring harness on the 2010 engine and retaining the CM2100 ECM. Consequently, a separate PCM would be required to control the 68RFE transmission, adding complexity to the wiring and integration process.
Option 2: Upgrading to the CM2200 ECM
This option involves procuring a CM2200 wiring harness and ECM, specifically designed for the 2010 engine. While requiring the purchase of a new ECM and selling the existing CM2100, this approach simplifies the transmission integration by eliminating the need for a separate PCM.
Considering Time Constraints and Live EFI Compatibility
The project has a deadline of May or June for completion, necessitating a timely decision. A critical factor is the availability of Live EFI support for the CM2200. Information regarding the earliest availability of Live EFI for the CM2200 and the process for joining the beta program is crucial for determining the optimal path forward.
The decision hinges on balancing the immediate availability of the CM2100 with the simplified integration offered by the CM2200, coupled with the critical requirement of Live EFI support for timely project completion. A thorough understanding of Live EFI compatibility timelines is essential for making an informed decision.
