82% Max throttle position
82% Max throttle position
Hello all, I have a 2015 Mazda 3 2.0L with manual trans. The only mods I have are the Corksport Intake (2.0L), Corksport Air Box, Oil Catch Can, and 2.5L Throttle Body. I installed the "Manual Trans 93 octane" tune on my car but today I was logging data and noticed that when I push the gas pedal 100%, all the way to the floor, the Versatune data logger showed a max of 82% throttle position. Is this normal or does this have to do with the tune not know about the 2.5L TB?
Re: 82% Max throttle position
The throttle will open to 77-78-80% maximum, above that it basically starts reverting and closing from the other direction.

Re: 82% Max throttle position
Gotcha, thank you! Do you think it would be better to go back to the 2.0L TB with the tune? Or would it make much of a difference. It definitely made a difference before the tune, the ECU seemed to adjust just fine to it but I don't know much about the tune. Would the tune also adjust to the slightly larger TB the same way the stock ECU would?
Re: 82% Max throttle position
And if I did go back to the 2.0L TB, would I need to reflash the tune again would could I just unhook the battery?
Re: 82% Max throttle position
Disconnect the battery or reflash your last tune to force the ECU re-learn the TB min and max points...
