Anyone have 94 L65 2WD?

[buddy]

I'm looking for the E-PROM codes in the ECM in 1994 C2500 and C3500 "F" L65 engine vehicles with 5521 injection pump and auto tranny.

The code is real easy to get if you have factory ECM, take 4 screws off glovebox and youll be able to see the ECM in the corner of the dash with a sticker that has a 4 letter code in the top right corner, like BPAA or BMXL etc....

the pump # youd have to use a little inspection mirror because the model number is on the front of the pump facing the intake, but easy enough to read.

Thanks For Any help.

My 94 "F" K2500 auto had(switched to Max-E-Tork) a "BXRT" EPROM in it. The PCM case said it orriginally had a "BKWJ" EPROM in it.

It has the IP like the 95 and later trucks had, IIRC thats the 5521 pump.

IT might of orriginally had the other 94only pump, that may be why the broadcast code on the eprom dont match the case code.

Wow, you got yourself a fleet of 6.5TDs. Thanks for the info. For some reason 2wd vs 4wd matters on those codes as far as they distinguished them, although the chip I'm using now came from a 95 K3500 and seems to work fine in my 94 C1500.
