So I'm looking for tire pressures and I think there is an issue?
Race chrono is taking the 15 and 02 for A and B. I think it should be taking the 02 and c8. 15 is part of the PID return data (622815).
You can manually define the response header to be 0x622815, and then the "A" will point to the 0x02.
Also I think your equation is wrong... (256*A)+B will make more sense.
Thanks for responding. I actually was testing the equations in Car Scanner on iOS, but they are all 3 similar with different syntax.
I just moved the letters down one. Change A to B, B to C. But yes, I meant that to be a multiplication sign. (256*B)+C… worked fine.
