OBD II bluetooth dongle - will it work in Polo GTI?

[bakersdelight]

I am just wondering if anyone has tried this:

VW Auto Car V1.4 ELM327 OBDII OBD2 Bluetooth Diagnostic | eBay

I want to hook it up to my car and connect it to the Torque app on my android phone, it should be fun....

I got one and it works ok on my S3. I don't trust the diagnostics though, I know the S3 has a secondary air issue, the pump is removed. It doesn't pick that up.

You're right Gavin. It's not good for detecting the faults. I had the overboost problem on one car with the faultlight ON and ELM327 was happy to say "no faults". But hey, I bought it for fun and for less than $30 inc. app for the tablet, it's good, and it entertained me for a couple of hours.

that'd be pretty cool when coupled with a lap timer app (and probably an external gps unit), like harry's lap time for iphone. Can't think of android based ones off the top of my head.

Torque seems to be the Android app of choice for this. There is also one called aLapRecorderHD.

The biggest limiting factor is the slow ODB rate of the ECU in the 9N3. I only get 1.2Hz updates at best with my Kiwi wifi (on the MkVI Golf, I get about 6Hz) according to Harry's Lap Timer.

just wondering how accurate the boost readout is?

its an estimate, the polo calculates the probable boost from other sensors.

Are you sure? I reckon it looks at measuring blocks like VCDS does. Seems extremely close to my boost gauge too.

There would be conversion from Mb to PSI, that would be all though.

I was under the impression the Polo used MAF readings and other measuring tools to approximate the boost.

If there was a air pressure device, I could use it for digital boost gauge like in the TT.

If you are talking 8N/1.8T TTs it's the same ME7 ECU.
