06-18 5.9L & 6.7L Cummins CSP5 EFI Live Switch
These cables are all PASS-THROUGH design and have another port to plug into to do diagnostics. NEVER try to tune a truck without plugging directly into the factory OBD2 port.
CSP5 allows users to switch on the fly between 5 user defined tunes.
30 individual tables are available for modification in each of the 5 tuning slots.
Some trucks (normally 13+), may only offer 4 tunes. Some Cab & Chassis only hold 2 positions.
CSP5 Tunes must be written using the following software release or later.
- V7.5.7 build 244
- V8.2.2 build 236
- Boot block 2.07.06
- Firmware 2.07.51
