New!!OBD2 Com with Xsim3 and Arduino-New!!

RPM is /4. The formula is OBD2 standard.
The extended RPM with EA or EF is RPM/10 to reach 655350 RPM, you told something about above 100000 which is above 65535.

With laptime you are right, it is cutted to 65535 (FF FF) because I forgot to change it up. It must count up to this value then stay FF FF.
Did fix this for the future.

Thank for your info.but I still not understand why rpm need to reach 655350, is 65535 not big enough（i not sure which car will exceed such rpm）？and why you said that i told somthing above 100000？the value i test is 1236( the value is from the input data window）.

Changed. RPM with EA is now 65535. Laptime should be working now with 3.0.2.8.

Hi,

Hey all,

I have the arduino uno connected to an LCD 162c, exactly as described on page 1st
If the code on the Arduino Uno was transferred data are not available (nothing)!

What is wrong, I still have to do what?

OBD2 is connected to the interface of the Arduino!

regards
Chris

Hi,

In xsim extractor did you go to the menu obd2 interface settings to add the com port ( which arduino plugged to and normally recognized by extractor) to the selected window comport to validate data transfer?

[TheXRacer]

yes adruino the board is wired according to your plan and was in the extractor com.port connected! LEDs flash as in your video and the board is controlled only the LCD display indicates no data!

Could you please again check the wiring on page 1?
Should I post images?

Use only the lcd162c!

Thanks for your help!
