You can watch in real-time the TPS value as it changes when you click the buttons. hello, I want to inform you that TPS calibration button doesn't work at all with '05 AT RSX PND ECU. I believe that TPS zero point just resets every time I turn the ignition on. when I've played with this feature usi...

OK, if I have a 05-06 base auto RSX - should I stick only with PND Auto basemaps as a starting point and tune from there, or other basemaps (PND MT, PRB, etc..) can be used too?

thank you

If the TPS value didn't change when you hit Calibrate 0 then your TPS is way out of spec. You'll need to adjust it physically. it's actually at 0.37V (7.5% absolute throttle position) when closed and sometimes I get TPS error codes. nevertheless, I've tried to play with throttle, opening it slightl...

check that Misfire Monitor is enabled in your firmware file.

of course this was done after loading my firmware file and connecting to the ECU. green bars at the bottom of KTuner window say "Connected" and "Live Settings".
I've tried to reupload the firmware after playing with the buttons but that doesn't change anything either.

there's a cheap $1 fix for this problem. if your KTuner rev0 board doesn't start when it's cold outside, you can replace the U1 voltage regulator on the board with Texas Instruments UA78M05QDCYRQ1 . the one that's installed on the board is not rated for usage in cold ambient temps. https://pp.vk.me/...

the cause of the problem was low compression in two cylinders; I guess that O2 sensor was just flooded with unburned fuel. after rebuilding the engine the sensor works fine.

I've just tried that. when I click the buttons, the TPS value doesn't change at all.
KTuner 1.0.4.2, rev0 board, PND ECU from 05 Base Auto RSX.

Idle Target
TPS Calibration

can you add some sort of UI feedback to TPS calibration? maybe show the saved TPS calibration value, etc..?
now it seems like that these buttons essentially do nothing

what is the purpose of removing the IACV?
