Starting with version 18.3.5, LapTimer features experimental support for parallel OBD requests speeding up update rates by 50 to 150%. For this first version, I have decided to give it an "experimental" status. It is turned off by default. There are a number of pre-requisits to use this mode:
- You need to run the top level LapTimer edition for your platform (Petrolhead for Android and GrandPrix for iOS)
- The car needs to feature a modern CAN based bus protocol
- An ELM327 based OBD dongle is required; I tested both PLX Kiwi and OBDLink LX/MX dongles and all worked
- LapTimer ‣ Settings ‣ Expert Settings ‣ OBD Tweaks / CAN Multi Requests (ELM327) ‣ 3 PIDs / adaptive
Once I get enough positive feedback, this feature will be turned on by default and simplified.
For our tests, please check Facebook post #1 and Facebook post #2 As an example, the update rate for a Porsche 997/2 increases from 11 to 17 Hz using an OBDLink MX Wi-Fi dongle.
The Android version 18.3.5 will be available on Playstore in an hour, the iOS version will follow in roughly one week.
