Anyone ever calibrate the Zeitronix TPS scale?
 

So, I noticed today that my Zeitronix only registers 0-90% TPS... If I push any harder on the pedal, it's gonna become a Flintstones' car.

I looked through the manual, and through all the options I could find in the software, but I can't find a way to calibrate it...

Anybody know if it's possible and how to do it?

TIA
