eprom upgrade...looking for info...Abe, are you out there? 900 1995

posted by  someone claiming to be keefus on  Tue Dec 12 03:57 CST 2000 [RELATED]

I have been investigating the eprom upgrade (service bulletin 28-102) that is supposed to correct the cold start/cold idle issues inherent in some of the LH 2.4 cars (95 945T). I was able to sweet talk a local Volvo dealer's parts lady into FAXing me both the table showing which eprom kit goes with which existing ECU (parts bulletin 28-24), as well as the 5 or 6 pages describing the procedure.

My problem is this: the table with ECU numbers doesn't list my ECU (6842448-4) under the "B230FT w/EGR" heading. The closest thing I can find in the table is (6842115-5) for a "B230F w/o EGR". There is also a notation saying if my ECU number is not listed, I need to go to Parts Bulletin Group EXC 28, #2.

I feel like I have worn out my welcome with the parts department, and if anyone (Abe?) has any info on which eprom kit I need (271843-5, or 271844-3) to install, I would be very grateful.
