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:
