All -

I just got my FJO logging kit installed and have a quick question.

Do you all use the Aux 5volt input from the TPS? This is what I have used and noticed that:

When the AFC reads 0% - volts = ~.45
When the AFC reads 100% - volts = 3.50

From what I know, i'm good at the idle / 0% voltage of ~.45v - however, when I floor it - shouldn't 5.0v display for WOT / 100% throttle?

I need to bust out the multi meter tonight and verify the voltage, hell, maybe the FJO software is reading it wrong. I mean, the car makes power at WOT (621.2rwhp @ 18psi) - but the voltage suggest that when I floor it, the car isn't actually going to WOT? -yet, the AFC reads 100%?

Any ideas? Bad TPS ?

Besides that is there an formula to convert the logged volts to throttle % (same way AFC displays it)? I came up with a basic formula and graph which plots a linear curve and I think it's pretty accurate - just wondering though (I'll compare my graph points to real life this week).

Another thing - exporting the logged data to Excel makes reading it and creating an A/F over RPM chart much easier!
