ADS def editing.

In an attempt to learn more, and see the values I can actually use, I am setting up new value tables for my $42 ADS def file.

I'm having a hard time with the TPS % setting, but will look at that later, when I get connected to the truck again.

What I have working or what seems to work pretty closly to what I think should be proper is MAP Kpa, since all table values are defined by Kpa, not MAP voltage.

I used operation of Multiply, factor of .4 and offset of 0. I didn't do any math for the factor, since I'm still not sure how to calculate this, I just tried a few different values until I found one that looks right. I have a feeling that the value would be 0.3921569, since that's what Mark said to use for TPS percentage, that would have a range of 0 to 100%. This will work for 1 BAR MAP sensors, I'll have to figure out a value for 2 and 3 BAR MAP sensors.

I've been using a datalog file to view and watch the new gauge as compared to the original volts based MAP gauge.

What have you guys added, changed, or played with?

Well the MAP conversion seems to be good, I'll have to compare it to a gauge at some point though.

I believe the TPS % while reading high at closed throttle might just be reading right. Well as correct as a Ford TPS on a GM ECM can, due to a constant that I found in the larger def file, more on that later.

I also tried using a different, larger (more defined) xdf, that had a constant for TPS % for closed throttle logging shows about 17% at closed throttle, I currently have the bin set at 20% for closed throttle), and seemd to make a HUGE differnce in the way the truck was able to idle, along with the stall saver constansts. The idle still wanders but soooo much better than what I was able to do before with less definition.
