FLS/FTS			Settings remain unchanged

NOTE: FLS/FTS Settings remain unchanged. Version "C" software can only flashed into a version "C" ECM, part # 1720802. Version "C" and "D" software can both be flashed into version "D" ECM, part # 1567172. The difference between version "C" and "D" is that "D" has J1939 data link support. 990hp @2100 will be upgraded to 1000hp with new non-prime injectors/software. 600hp @1800 will be upgraded to 605 with new non-prime injectors/software. Flash Files with an interlock code change will require a password not available in TMI. Reference TIBU4286 for this password. You must have this password to complete the repair.

ACTION REQUIRED

Move the rail pressure sensor from the front of the right-hand cylinder head (looking from flywheel end) to the rear of the left-hand cylinder head.

Remove the existing plug and swap locations.
Install a 1323144 wiring harness extension.

NOTE: The new software strategy incorporates a 6 cylinder feature while in cold mode. The engine will run on the 6 left bank cylinders only while in cold mode. This will accelerate the warm up period while eliminating the white smoke.
