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!

No sweat. Anytime. Just ask if you want to see anything else in particular.

EDIT:

The graphs don't look that bunched up when you only have one or two in the window....you can make them full-screen and get some resolution out of them.

Well since you offered, how bout some Mass Fuel Desired, or SOI maps, next time you get a chance.

Thanks in advance

Got a minute?

[907DAVE]

Yeah buddy!

Stock PMT1 stuff. SOI, SOI delay, Pulse width, PW multiplier. For me to post and you to figure out......

[907DAVE]

Awesome...thanks again
