New to Harrys Laptimer on Android and have a few Questions

[Ralliartz]

Hi

I'm new to Harry's Lap Timer and have it on Android.

I have a few questions:

1) I have an OBD 2 bluetooth adapter connected and it appears to be working fine. In the video overlay is it possible to add other gauges than the pre-defined ones?
2) For the current boost gauge can units be added to see how much boost is actually being produced?
3) The data that Harrys laptimer receives from the OBD 2 adapter is it possible to log that and export it somehow?
4) Can Harrys laptimer access canbus?

Thanks
Jarryd

Any info regarding the above would be greatly appreciated.

Hi,

1) In case you want custom overlays, try one of the desktop over layers (Dashware or Trackvision).
2) The gauge ends at +1.2 bar, the gray area marks less than atmosphere: -1.0 bar to 0.0 bar
3) Most of the OBD data is logged and stored just like GPS and acceleration information. Select any lap recorded with OBD and select Export. There are several formats available, try CSV e.g.
4) LapTimer accesses the functional OBD 2 layer only - which includes mapped CAN data. LapTimer does not support physical / bus specific access.

Thanks for the reply Harry.

I have the following information:

Is there a way to implement these? The above are addresses from a program called Evo Scan. They are in CAN X-Y format?

Any ideas?

Basically the big problem with all the OBD apps I've found is that there has been no way to monitor Transmission Temperature in an Evo X and/or a Ralliart Lancer.
The above information is from a program called EvoScan which can monitor this information.

Thanks

Yes, that is vehicle specific CAN information including mapping description. As an extension to read such data requires a car model handling, a way to customize codes and add evaluation, add to LapTimer's database scheme (including display, import / export, etc) and the extension to request data on CAN level, this is still a labour intensive request. I may add this in the future in case I find a good generic solution and other car types get available too.

Thanks for posting!

Harry it sounds like a bit of work to add but wow if this is trully possible Evo X/Ralliart owners would be extremely grateful as there is no current "cheap" solution to monitor this specific information. For instance I was at a trackday yesterday and to be able to monitor a $10000 gearboxe's temp would have been invaluable, I didn't recieve any over heating messages but several other people do when they go to the track. If it goes over 130 deg things melt.....so yea, is it possible to look at implementing in the short term?

Thanks

Ralliartz,

A Kiwi Wi-Fi OBDII dongle connected to a laptop running Hyperterminal or whatever is the modern equivalent will allow you to access anything that's available on the CAN bus, if you know the correct PID's. What you have listed may be the CAN bus addresses, but that doesn't help to access them through the OBDII port. The reason there is no "cheap" solution is that those codes are proprietary and the manufacturer charges an arm and a leg for them and requires you to sign a bullet proof non-disclosure agreement. If you ask really nicely, it's barely possible that you might be able to get a very few specific PID's that you can program into Torque or, if you're good at C++, into something like this http://arduinodev.com/store/?route=prod ... duct_id=58.

[Ralliartz]

Unfortunately I'm not a C++ wiz and don't quite understand how to use that equipment. I've done a lot of digging to try and find the PID for those but to no avail. The above is the only info I have stumbled across that points to the trans temp.
