BRZ/FRS update rates?

Postby cgroppi » Mon Feb 23, 2015 1:25 am

Could those people with BRZ/FRSs post what OBD2 update rates they're getting with HLT?

I have a Chinese knockoff Kiwi PLX wifi clone, with an iPhone 5s and a XGPS160. I was getting about 2 Hz before enabling the CAN multi request option. Now I am up to 4-5 Hz but am wondering if I can get an even higher update rate with a different ODB2 dongle, or if the slowish update rate is just the car.

Edit: I excluded a bunch of irrelevant PIDs and now get a solid 5 Hz, which I bet will be fine. More is always better, though. I'd prefer 10 Hz.

As it seems your car has a CAN bus, 5 Hz with parallel requests is pretty slow. Check the OBD Benchmarks post some topics above to see some samples for genuine adapters.

Success!

I rolled the dice and ordered an OBDLink MX WiFi. I figured most of the complaints involved the infrastructure mode needed to use it in concert with a GoPro, which I don't use.

It seems to work fine, and I was able to get update rates of 18-20 Hz with CAN multi request enabled. And that is with no PIDs disabled. That's quite the improvement.

Now, to see if I can get the thing to work reliably. I have yet to test it at an autocross event, just in the driveway. I was able to maintain a connection with no trouble for 10 minutes or more, but I won't be fully convinced until I see it work reliably for an entire autocross event.

Yes, it is really fast! Keep my fingers cross for the reliability. :-)

I tried the ODBLink MX WiFi for the first time today at an event. It worked perfectly all day. No connection problems, and HLT connected quickly each time I slept the phone then turned it on again.

Note, this is NOT with a GoPro. Just the ODBLink with HLT.
