Accelerator Pedal Position

Post by quickdraw »

Hi,

I've just installed Versatuner and flashed the base 93us/98 octan version 1.00 as I wanted to get more familiar with the tuning process before trying to high load tune.

I noticed that the peak boost pressure is around 15-16psi, and maximum load is 1.6. But what is most interesting is i'm only seeing 66% APP and 30-35% for relative throttle position.

Now i've read that 66% is normal on the Gen 2s, but shouldn't the relative throttle position be much higher?

Here is a screenshot from a log

That looks about right for a stock gen2, that's how the pedal position sensor is calibrated.
If everything looks fine on that log you can go with the high load no problem. PM me if you want to go custom.
