Hi guys and girls,

I've got a cheap China obd2 dangle and I'm finding it's not providing info that well to the different software packages.

The main one I want to hook it up to is Harry's lap timer grand prix edition, I'm not sure if it's to do with the Volvo canbus or the dongle being crap.

My $8 ELM327 works fine. Some parameters dont update very fast but I checked via some different software and it looks like the OBDII for some values like engine temp get fed to the obdii at like 1Hz. Used it on many different apps. Thr only issue I have is initial start up and pin entry.

What info are you missing? I'm using a wifi dongle from Amazon and the DashCommand app and have a pretty big selection of supported PIDs.

I have a cheap bt odb2 and use it with torque on my phone. I have no issues. You obviously won't get the volvo specific codes or module interaction. The icarsoft can do that though.

I've got some stats using torque, but I can't get anything via Harry's lap timer.

Most of these dongles are optimized for 4g devices FYI, just in case your using an iPod or tablet. It will appear choppy on none 4g devices.

I think it's the dongle, I tried it in my wife's car and with 10 different obd2 software apps and it didn't work. So I ripped it apart like anyone would and noticed a lot of pins didn't have solider on them.

I might try soldering them up and see what happens or just order a new one.

If anyone is interested here is what the guts look like:

I have a few mini 5 dollar transparent blue ebay ones and one of the larger black ones I bought from China like 8 years ago and they both work fine. I would just order another one.. They're so cheap now. But I'd also solder the old one lol.. We have one in every car. You never know.

Nah, I live in New Zealand. I ordered them from AliExpress as I looked on our version of eBay - trademe - and the $4 Bluetooth dongle are selling on it for $15, I couldn't handle the price difference so accepted the wait. The worst I saw was a $10 dongle being sold for $55.

Ill see if I can steel one from someone for the day if they don't show up.

Went through and touched up all the solider joints making sure it didn't become a bridge between bits, threw it into the car and boom it connected.

Then the car came up with a brake failure warning light and refused to start...

Disconnected the battery and threw the dongle into the bin, waiting 10 min and reconnected everything and no warning lights and the car started... Whooooohhhoooo

I'm searching a good app for Windows Phones.
Haven't found any (free) programs with Charge Air Pressure (Boost) reading?

Any suggestion?
No problem in paying for the app if confirmed that it works.
