I've been bad....
 

Bill,

Over the past couple of days, I've been comparing some existing programming that I have been holding on to. I noticed something between the three files you sent me when I received the emulator and three that I have from a certain silver programmer.....

I am not looking for ANY handouts on how-to or why.......

What are the actual definitions for FN028, FN029A, and FN029B? What are the values for the non-defined axis (pointer)? They make a HUGE difference in how badly the truck surges while going downhill at cruise speed. :shrug: I'd like to figure out what is actually being altered here and why it makes a difference.

Thanks a bunch!

I'll let his know this post is here waiting for him, Cody. :thumbs up yellow:

FN028 is the Mass Fuel Desired normalizer (X-Axis) for the Fuel Injection Pulsewidth table.

FN029A is the ICP normalizer (Y-Axis) for the Adder to Pulsewidth Multiplier.

FN029B is the ICP normalizer (Y-Axis) for the Start of Injection Offset.

Thank you, Bill.

:howdy:
