EvoScan 2.1 Fuel Trim Formula

Guys, I've been having a time trying to get 2.1 to log fuel trims correctly. I've tried 2 different formulas and I'm not sure which one is correct for 2.1 ...

(0.1961*x)-25
(0.1961x)-25 (which woks great in .99)

I've found a couple of typos that were my mistake, but those have been fixed. I just need to know if 2.1 requires the "*".

Thanks.

What does this formula do different than 0.78125*x

I thought the 0.78125*x was correct.........?

The formula I posted changes EvoScan's base 100 values to base 0 values and changes the scale to +/- 25.

(0.1961*x)-25 seems to be working now ...

Hi, does this formula need to be placed in the oxygen feedback trim (STFT)?

i'm guessing it does but would like clarification.


Mark.
