Those of you looking for a cheap Wifi OBD reader..

Post by spets » Mon Jun 13, 2011 2:44 am

This one is for sale on Ebay for $85. I purchased one, it arrived to me about 15 days later. It sucessfully connected with Harry's Laptimer and I am getting an update rate of 1.6,1.7 Hz.

I did a little test drive, it is awesome having RPM, % throttle, and gear. I set my green zone to the VTEC engagement on my Honda S2000. All I need now is a better camera mount for less shaking.

Here is a quick test video I took. I will visit the track at the end of the month!

Does this work as well as the PLX Kiwi wifi? It passes all the same information?

Yeah, it seems to work just as well. I don't know what kind of update rate the PLX one has, and maybe that is something that is car-dependent. I also got the FuzzyCar app for my iphone and it picks up all of the data. Fuel trims, coolant temp, intake temp, engine load, throttle position, rpm, manifold pressure, open/closed loop, o2 sensor voltages, etc. From what I can tell the OBD scanner is fully functional.

Just be aware that it ships from Singapore so it might take ~15 days to get there.

As far as I know, the update rate depends mainly on the car's bus and not on the wifi interface. Newer cars usually have higher rates than older ones, simply because the processing power of the cars' electronics is getting higher year by year.

Yes, exactly. The OBD dongle adds some extra burden (e. g. WLAN will not be as fast as a cable based device), but in general, the car's bus speed is the dominant component.

@speds, did you connect the device using custom OBD settings in LapTimer? Or did it connect to LapTimer without configuration (except the WLAN connect, that needs to be done anyway) and shows up as KiwiWifi in the Sensor List?

This is what I expected, the devices look pretty similar. Seems to be an un-branded version.

My friend also purchased this unbranded device. The only functional difference we can find is that the PLX Kiwi has an on/off switch.

I have my PLX discretely installed in the car and use the on/off switch so it's not turned on all the time, especially in the summer heat. Otherwise you have to pull the OBDII connector.

I also bought this product. While I can get it to connect, there's no info going to laptimer. It states it is connect in the setting menu, but the update rate is zero. Any help would be appreciated
I did do the firmware update and connected it to IP: 192.168.0.11
