Look, I am not math challenged. I am a programmer (in a dozen languages) and I am a Chemical Engineer.
The statement is not clear, that's all.
An example would be nice. Especially since this apparantly is different from what you have in your sticky files:
"5a: Fuel trim approach: Let's say at .800, .28 which is equivalent to 800 RPM's you have 4 which is equal to +4. For ALL YOUR TRIMS you want between 0 and -4, so what I do is do whatever it takes to get to zero. Easy rule of thumb here if you want number smaller, add you want number bigger subtract. So, we want to bring that DOWN to 0 so ADD 4 to .800, .28. Let's say 2.0, .20 is -10, SUBTRACT 10 from 2.0, .20 to bring it UP to 0. This will not work out exactly but will get your PRETTY CLOSE. "
So apparently, the above is not correct. A detailed example of what is correct would be nice and perhaps revising your tuning file might be in order.

As far as Autotune goes RTT is an extention of our Custom operating systems which means you'd need to apply one of our custom operating systems to take advantage of either. And to make good use of autotune when it becomes available you'll need to understand the fundamentals of tuning ie if your having the autotune feature add or subtract something thats supposed to be getting multiplied you'll run into trouble quicker then NOT using the autotune feature
