NVK4 isn't half bad for DD.

[Power Hungry]

The list of automatic PCMs I have driven:
MRT2 (super suck)
NVK2 (sucks)
NVK4 (not bad)
MNM0 (NVK2 wanna-be)
MNM1 (not bad)
PMT1 (awesome)
PMT2 (not bad)
PMT3 (not bad either but didn't notice a difference from PMT2)
VDH2 (suck)
VDH5 (super suck)
TDE0 (ok)
TDE1 (better)
NAW4 (absolute crap)
LKM6 (TDE1 wanna be)
YBT1 (garbage)
XLE4 (sucks)
XLE8 (not as bad as 4 but still sucks)

Cody,

If you ever need any stock calibrations, I have a whole library of every released version since the 7.3L was released.

For reference...

PMT1 --> PMT2 --> PMT3 --> CKX0

PMT2 and PMT3 have zero changes between them.

PMT3 and CKX0 have four changes:

• Manual Pull-In changed from 30 MPH to 28 MPH
• 1-2 TV Minimum changed from 19.5 PSI to 40 PSI
• Function FN103 is modified (Unknown)
• Function FN1CB is modified (Unknown)

NVK4 --> VNK5 --> MNM0 --> MNM1

NVK4 and NVK5 have a significant number of changes between them.

NVK5 and MNM0 have a significant number of changes between them.

MNM0 and MNM1 have zero changes between them.


TDE0 and TDE1 have a number of undefined changes in what would be considered the "OBDII" section.

In any event, there are a number of files that have very much in common and other that have very little in common, even among the same families. It's always interesting to see which files people prefer for certain types of driving.
