On a 2005 NC MX5 Miata, LT is only showing 98% throttle when pedal is flat - data is coming from kiwi BT OBD. Kiwi's own BT app verifies that throttle goes to 100% when I test it. I have not tried different Throttle PID in LT (e.g. Position B/C/D etc.) as I'm not really sure what this does? LT obviously knows the throttle PID as the data works, its just perhaps not scaled or something. On this ECU, throttle PID (mode 0x01 PID 0x11) is reporting pedal %.
As an aside, it seems odd to me that this throttle PID OBD tweak setting in LT is in the "global" administration setting section and not per-car ??? Couldn't it be different per car? Minor issue I guess.
Throttle % only showing 98% in LT
Re: Throttle % only showing 98% in LT
Throttle data delivered by OBD is a value between 0 and 255. But 100% is not 255 but an arbitrary value depending the individual sensors of the car. What LapTimer does is monitoring all values coming in and memorizing the max value. This is considered 100%. So this is an automatic calibration that requires you to floor throttle at least once. This calibration could be further improved by memorizing the max value's timestamp and expire that data after a few minutes. I assume your car delivered a max value at a certain time usually not achieved. A non-standard peak. LapTimer used that as 100% mark but further readings didn't read this value again. Next time the sensor is reconnected, calibration will start over. I add the improved calibration to my feature requests list.
Throttle PID $01$11 is default PID used. Some cars deliver better values for $01$47-$4B. You can check the PIDs available for your car by selecting the OBD sensor on Sensor List while the engine is running. Sensor Information will show all PIDs available. Position D is often the best choice (if available).
Expert Settings are what they are named.
I introduced them for trouble shooting individual cases and 98% of LapTimer users will never use them. There are many expert settings implemented as global values that could actually go into individual vehicles, sensors, smartphone models etc. It is always about a balance between effort and value. And this list is incredible long, isn't it?
