LOL.....yup will make it harder for sure, but if you dont mind posting a few I wouldnt mind looking at them.

YEP let's See em' Cody

Here are a couple.

Anything in particular you'd like to see?

The first one is a few of the shifts in a heavy towing program (blue) vs. stock (black).

EDIT:

The upper left is 2-3 shift, the upper right is 2nd gear TCC apply, the bottom left is 3-4 upshift, and the bottom right is the 4-3 downshift.



This explains some changes. I sent this picture to "Pocket" on PSN because he was wondering about how much "tinkering" can be done with the shifts. Black is the towing program. Blue is something else.....and red is stock.

Nice, wish they were a little bigger. So the left side of the graph is MPH and lower is Throttle Position? If so what values are used for the TPS?

[cleatus12r]

Sorry, I should have used Photobucket......

I'll edit that post and put some REAL pictures in it. I forgot that attachments came up tiny.

Hang on a minute....

EDIT: THERE THEY ARE.

MPH vs. APP in A/D counts.

[907DAVE]

Wow......really cool stuff. The A/D counts seams a little hard to relate. Heck I am sure that all of it is going to be hard to relate to. What are the #'s in red, different map?


On edit I see what he red is now.

[907DAVE]

Ohhh man...... dont know if you should have done that, lil excited now!

So would you say that 600 a/d counts would be roughly 1/2 throttle or more like 2/3?

From Cartechbooks:

"Ford EECs convert most voltage inputs from sensors (MAF, TPS, etc.) into an A/D count before actual processing. Some software packages normalize this to only show voltage values in the editor; others leave it as counts. The actual scaling depends upon the clock speed of the processor being used, but it always works out such that 0 to 5v reference signals become 0 to 1,023 A/D counts."

It's just the way the PCM relates to input voltages....without using actual voltage. You can assume that 512 A/D counts will be 2.5 volts. Just keep in mind that the A/D on most sensors....especially the TPS...will never be 0 counts but more of a minimum of 70-80 counts.

Ok, makes sense. Should be pretty fun to do once you get it figured out.

Thanks Cody!
