Will this work for a Honda Fit?

I can't stand the TPS being at like 15 when the accelerator is not depressed.

If your Fit supports the mode 0x01 PID of 0x45, that gives relative TPS. On my FEH, the absolute TPS is 12 when not depressed but the relative TPS is 0 when the pedal is not depressed. If you go to CMNDS, enter 0145 and hit send and see if anything comes back.
If so, you could program an xgauge as follows (assuming CAN):

TXD:07E00145
RXF:044185450000
RXD:2808
MTH:00C800330000
NAM:Tps

Has anyone had success converting this into a custom Torque (Android app) PID? I've followed the formula given here by Aberk, and it doesn't seem to give proper readings, ie not depressed position = 900%

Any help is much appreciated!! Cheers

Dan's original post is not an OBD-II PID based xgauge, it is a bus-sniffing xgauge. Don't know if Torque can handle that.

Thanks for the quick reply CarlD, that explains it. Bus-sniffing means that the device is actively polling for information rather than reading off (passive) the OBDII data right? I guess my next question should be asked at the Torque-bhp forum whether or not the app support it...

Thanks again. Will report back if anything come of it...

Bus-sniffing means it's eavesdropping on all of the traffic flowing between computers during normal operation and no requests are made. PIDs are low-priority requests for information that the vehicle's computer processes when it gets a chance. The CAN address indicates its priority with higher numbers being lower priority. For OBD-II, 11-bit CAN addresses start with a 7 and are nearly the lowest priority. An address of 7FF would be the absolute lowest priority message. Critical information flowing on the CAN bus usually has addresses starting with 0, e.g. 043. If you look at Dan's original code, the RXF indicates that it is looking for a message with an address of 224, which is kind of medium priority but still much higher priority than any OBD-II request. The 8 in the RXF indicates that the result will be divided by 10 before being displayed. The TXD value is just the scangauge's way of saying "don't transmit anything!"

Since this is a message on the vehicle's bus, it is usually specific to that particular vehicle (and maybe even model year) so it is probably not usable for different vehicles even with the same manufacturer.
