Help w/ Harry's LapTimer Custom PIDs
I've been searching here and on the F80/82 track-related forum but no luck. Anyone know or have a link to step-by-step on how to set up a Custom PID on Harry's LapTimer? I looked at the app's documentation but can't make heads or tails out of it. My goal is to record coolant temp along with the normal lap data, and be able to see it later in the "Lap Analysis" menu.
Thanks for any help! |

So, looks like the BMW PIDs are not out in public and my wanting to record coolant temp in Harry's is not going to be an easy thing. I've searched quite a bit and best I was able to find was this: https://www.bimmerforums.com/forum/s...-specific-PIDs.
I will have to settle with monitoring coolant temp with a separate OBD scanner app but unfortunately won't be able to run it simultaneously w/ Harry's. |

Engine coolant temp is a generic PID (Hex 05, 1C/bit, -40C offset). That's what works for me using Torque with my 328d.

Do you have a list of these perchance?

I downloaded a copy of SAE J1979-DA, which has the OBD2 PID specs, but I don't remember from where. It looks like this site has the same info though.

Help w/ Harry's LapTimer Custom PIDs
Unfortunately no luck with these settings. Here is the screen shot as currently configured. I think my syntax for the formula is the problem. I tried the suggested
=(A-40)*9/5+32 and what shows in this screenshot. Harry's timer screen shows the field for "Coolant" but no measurement is displayed (just shows blank). : |

Why does the screenshot show "-40=A"?
Does just "=A-40" work to give you deg C, or even just "=A" to get a number?

A= =A =A-40 -40=A All unsuccessful. I know the coolant data point is available from the ECU because I can see it through another "Car Scanner" app, and also on TrackAddict, but for some reason, not coming up on Harry's. I will post the issue on Harry's LapTimer forum to see if anyone can shed some light. |

In Torque Pro you have to set the mode and PID in the same line, so for coolant I enter "0105" for mode 1, PID 05. I didn't think you'd need to enter the leading 01 because you have a separate field for mode. The next thing you can try is PID "5205". I saw a doc that said that's the internal address for the coolant sensor that's supposed to get passed onto the "05" generic PID. Not sure of those will work for you, but worth a try. |

I tried PID "5205" but still no luck. I've been reading elsewhere that the oil pressure monitoring might be a switch, and not a transducer with measure-able output.
Thanks Farkle for the tips but I am giving up on this one! |
