Can't get TPS 100 using EVOSCAN
 

Hi everybody! I'm new to tuning. I logged my EVO X yesterday using EVOSCAN and OPENPORT 2.0. I clicked the start button and then pushed the gas pedal all the way down to the floor, then I stopped it when it his the red line. However, when I read the log data, I found that the TPS just increases linearly with the RPM and it never reach 100. I tried a couple times and still have the same issue. Anybody know what's going on? Thank you for help!

There's tables that convert your throttle position to the actual amount the throttle body opens. I haven't played with it too much but I believe it's mostly to smooth out the response and keep you from shocking the drivetrain. Like when you lift at high rpm's for example.

Look for logs of the actual throttle position and see if those open all the way. You might be looking at the pedal position.

are you using mode23 datalogging? if yes, make sure you are using the correct requestid and formula for your vehicle. all EvoX mode23 have TPS enabled. it will show ~17% to 95%, even when stationary with the EvoX on but not started.

i have 2013 usdm gsr and i cant get evoscan to lot it, what do i do Hamish?

From my experience, most mine will read is 86.xxx, just like many things in the ECU, the number you visually see is only a representation of what is in the ECU, not the true value.

I donated to Golden and he got all the Mode 23 stuff working in my ROM file.
