Can you explain a few things to me please.

I'm not too sure what the Exhaust back-pressure torque loss map does or what Normalizers and Multipliers are for.

Also are 1020 AD counts 5v? I thought the pedal only put out 4.7 or something close to that so I just wanted to convert AD counts to voltage.

Ill start with just those because they may clear other things up.

Thanks
John

EBP torque loss map, I wouldn't really worry about it. I'm guessing the values might be subtracted from the Indicated torque or Torque table. One of those tables has an affect on shifting pressures, but don't hold me accountable to that if I'm remembering wrong, I'll try to find the thread covering the shifting part.

Normalizers are used to control values in the X or Y axis. Notice on the Fuel Limit vs RPM it ends at 4000, you can bump up or down the maximum. You can also control where the values in between will lie on the axis. Quite a bit tricky to grasp.

Mutlipliers, are as they sound, but exact explaination isn't so easy. I know I've read something in this forum before.

Yes, you're right about the 1023 counts being equal to 5v. Here's an older post from Cody, from this thread here

Keep in mind that the APP sensor DOES NOT put out 0 volts, nor does it go all the way to 5 volts. This means that you will never get 0 A/D counts or a full 1023 A/D counts. More like 100 to 918 A/D counts.

For those of you who have this "updated" MFD scale, you might want to take this into account on your MFD map.

Hope this helps.

Thank you yes it does. Ill toy with some things and be back with more questions.
