Dave said he's cool with me posting those maps here as long as they are used in the correct context.

I feel kind of bad for not waiting a little bit longer for him to get back with me.

Hopefully he can provide some more great insight to this thread.

In the mean time, I'll try to dig up some more visual aids to help the newbies.

what does a typical cold start map look like? PW vs. temp vs. ICP

Mine puffs real good when oil temp is below 40. PW often starts at 2ms and stays at 1.8 for quite awhile. Today after sitting in a shop near freezing the last two weeks, it started hard and was closer to 2.3ms for the first min or 2. When warm it sits at 1.3 out of gear and 1.5 in gear. Is delivered PW a result of other parameters or is it the calibration command?

is the high level of cold start PW commanded or a result of load? what in the calibration is contributing to what im seeing?

What are there adders and modifiers then? Take eot measurements and asjust timing based on that?

There is an EOT vs. Timing adder

I only have VDABO def files.

Fuel limit / RPM vs EOT
Fuel PW multiplier / EOT vs ICP
SOI multiplier / EOT vs RPM
Cranking MFD vs EOT
Idle speed RPM vs EOT
ICP offset vs EOT
Fuel density vs EOT

Exactly....there is no "cold start map".

Everything is based on one set of mapping and then fudged from there with adders and multipliers. Fun times.

This is why just giving away things makes no sense after spending so much time figuring it out.

Anything in that list that relates to eot, is essentially temperature compensation (cold temp, warm temp, whatever).

Thank you--in this case, there is a fuel multiplier. That's kinda what I expected to see, but my question was dragging out too many secrets earlier to be answered then... :doh:

Did you get minotaur?

sorry for not stating it correctly, thanks for the help..

Yeah I've had Minotaur for a bit. I am still running stock sticks but even with stock sticks I was able to massage canned tunes to resolve some issues. I like Minotaur so far. with Hydra it takes as little as a few minutes from making a quick adjustment, saving the calibration and loading the hydra.

Cool-- what have you been tweaking with?

The last time this truck was tuned was at a time when it wasn't real cold. Its always had cold smoke issues and thought that it could be dialed out if time was spent on it when it was cold.

Another area of investigation that I have to do is that I could have sworn that the OBD oil temp was 30-40 deg higher than the air temp or trans temp. Sender issue perhaps? Based on the map you showed, appears that will greatly affect the adders. I drive the truck so little that I don't spend a lot of time looking at it.

Dude, we get it. Thats like the final step in a file is fixing idle resolution or a haze issue. Or leaving it altogether.

If you dont tune anymore, why do you care? Bill sells minotaur. Dont you think if he gave a rats patoot he wouldnt have done that?

Is your truck mint? Your ccsb? It seems like you had some pictures up at one point. But i get you confused with another member sometimes. Sorry for that?

Mine is starting to get rusty again. Its been painted twice already. It rotted out in 4 years the first time but I plowed snow until 07. Which is why it was painted again in 07, after it started to rust, again. Smashed the bed loadin a boulder and wrecked the tailgate...

I get what your saying about giving tips and secrets away that it's take. You so long to figure out... On the same note it makes no sense to keep them to your self either. How is that helping anything or anyone?

It's kind of like myself and barefoot trimming horses. Over the years I've come a long ways in figuring out the best way to shape and grow a healthy hoof on a horse. I made so many mistakes starting out early in my days because I had to figure out and test different stuff to see what changes it would make. Sometimes it worked out sometimes it didn't. So my point is all these years of testing and trying out things to get to where I am today as a barefoot trimmer would be pointless if I didn't share my findings and my best practices to others that ask or need direction. The few hundred horses I trim would be sound growing healthy rock crushing hooves and the thousands others out there trimmed by folks that don't know the right way (or the best way) I should say and there would be a bunch of soft footed lame on rock horses....

Point is if you don't share your findings with folks there may be a bunch of lame powerstrokes running around! Hahah

But then again not everybody shares the same train of thought on sharing knowledge. To me knowledge should be free and work should cost money.
