Greetings! First I want to say thanks for this excellent program. Nothing I've accomplished wouldn't be possible without TunerPro.
The issue I am running into is with the expression editor. Here is the expression I am trying to use:
(500000.0 * 30) / (POW(2,((X+128)/32)) * 64)
The actual equation is:
rpm = (500000.0 * 30) / ((2 ^ ((X + 128) / 32)) * 64)
(fyi, this is for Bosch Jetronic LH2.4 )
When this equation is entered, TunerPro fails to recognize the 'X' variable. It is really the POW() function that seems to be 'hiding' it because if I enter this part alone:
POW(2,((X+128)/32)
it still doesn't see X. At this point I tried this to make it see X:
(X * 0) + POW(2,((X+128)/32))
Entering that equation makes TunerPro crash every time
Help!
If you want my Jetronic XDFs (for Volvo), start here:

Thanks!
Expression editor woes.

Function parameters are separated by semicolons.
You can also greatly simplify your equation, which will help performance. Some hints:
- Multiply out the numerator
- 64 is a power of 2. Combine it with your POW function.
TunerPro shouldn't crash, so I'll look into that.

I figured it could be simplified, I just got stumped when it barfed on me. I'll try and revise it. Thanks!
