A few questions

Bill,

What can you tell me about the manual strategies as far as "ideal" differences between say, MLE0/MLE1, and DAC2/3, etc. I can't say that I can feel any perceivable difference for either PCM family. However, ZHL1 seems to work really well over DAC3 with similar parameter changes. Why would that be? Comparing the scalars, tables, and functions of each stock file really doesn't shed any light on anything. I would think that a manual transmission tune wouldn't have the "cult" following like the automatic base files do.

ZHL1 is VKAE4P8 which is much more closely related to DAC1 which is VKAE1P2 or DAC2 which is VKAE3P4.

DAC3 is VOAA7P6 which is a later strategy and is SIGNIFICANTLY different in both layout as well as functional values than the earlier VKAE based files.

This is similar to the PMTx phenomena. Nobody is really sure why, but PMT1 is a really solid calibration and PMT2 and PMT3 suck eggs. They are all VRAA related strategies, but the later PMT files (including CXK0, which is basically "PMT4") just don't muster up to the performance of PMT1. The calibration values aren't all that different so I'm a little confused why the big difference in the way the trucks run and shift.

Anyway, with so few M/T trucks (at least compared to A/T ones), there hasn't been enough opportunity to swap cals and see which ones kick butt and which ones don't. Maybe you'll have a bit more opportunity to work with those and come up with the PMT1 equivalent for the manuals. It already sounds like you have a good head start.

As for MLE0/MLE1, there are about 12 changes between the files and they're not anything I recognize or have mapped in the RDT files. Other than that, they're identical.

Thanks for the input, Bill.

I haven't dyno'd (or more specifically, had my friend dyno) the ZHL1 vs. the DAC3 even though it's at his disposal whenever he wants it. However, my friend has been driving with assorted tunes from each family..two were duplicates of eachother, one of each. He won't leave the ZHL1 tunes. He doesn't like the way the DAC3 "feels"....even though EVERY scalar, table, and function are exactly the same in each tune. So I gave up on DAC3.

I think I found my huckleberry; it's the ZHL1. However, with all of the.......uh......not so good base files I got from the "other" company, it might just be a fluke.

Bill, here's a screenshot of what we discussed the other day. Just in case I read something wrong.....
