Engine/Transmission (1998.5 - 2002) SMARTY Ver.1.22B/Data 1.07A vs. Ver. 1.22B/Data 2.07A

[Spunkys Ram]

Does anyone know what the TSB for extreme cold weather climates is in Data 2. 07? Is it the high idle feature? Also what is the driveabilty enhancements for winter fuel include? Am I okay to run Ver. 1. 22/D 2. 07 living in 'warm' Arizona? I don't use winter fuel!



I'm in the process of updating and would like some better clarifaction. sp?



Thanks for any and all input.

Here is a copy of the TSB:
Driveability enhancements for winter fuel use and for hard starts.
This bulletin applies to vehicles equipped with a 5. 9L-24V diesel engine built between engine serial numbers 56419738 to 56798357, with a date of manufacture of December 16, 1997 to November 15, 2000.

The customer may complain of poor driveability when winter fuel is used to power the engine. Or, the customer may complain of a hard or no-start condition, while the engine is at normal operating temperatures, when using any type of good quality diesel fuel. The poor driveability condition may occur only when either straight #1 diesel fuel is used or when other special cold climate winter blend fuels are in use.

The no-start or long engine crank condition may occur when attempting to restart the engine while the temperature of the engine is till close to its normal operating temperature. This hard hot restart condition may be experienced in all ambient climates, but may be more of a concern in warmer ambient climates. The repair involves selectively erasing and reprogramming the Cummins CM551 Engine Control Module (ECM) with new software.


Hope this helps...
