pcm codes

allright just bought a dp tuner i need to get it reflashed. well i have a 94 just pulled the pcm out to remove the banks big hoss. now the previous owner told me that the truck was reprogrammed as a 96 or 97. will this change my code. here the code i hve now BEG6. that is on the pcm. But on the chip is engraved my hand MLE1. does any of this make sense any input would be nice thanks

Since the DP-Tuner chips are all 4-bank chips (meaning they COMPLETELY disable the program in the PCM), it really doesn't matter what the original code is in the the PCM. So, despite the fact your PCM says BEG8 (a 94/95 calibration), the chip will run the MLE1 calibration stored on the chip which is the latest code for a 97 M/T truck. If the PCM is in fact reprogrammed, the only way to tell what it is programmed to is to actually read the PCM ID using a scan tool or some other such device to identify the calibration filename in the PCM. Again, this is a moot point when using a 4-bank chip.

Incidently, the 97 M/T and A/T codes are the best all-around calibrations to use. They provide the best overall drivability compared to earlier calibrations and respond very well when tuned for modifications such as turbos and injectors. The latest code for the M/T is MLE1 and the latest code for the A/T is TDE1, just in case anyone is curious.

Hope this helps.

Most definitely. A 99 code will not work on a 97. Just give Diane a jingle and git 'r dun.

Take care.
