Anyone local to Neath/Swansea area that can check AFR's under load? I've got some small but niggly issues with my car and wondered if anyone has a wideband that can be rigged up on my car for a few test runs?

 

Dean, I am pretty sure that my VI monitor can monitor AFR readings, you are welcome to borrow it if you want.

 

That's very good of you Tyron and it would be good to do some data logging while it's in the car.

Do you know if you need a wideband lambda for accurate AFR's though Ty? As the VI Monitor uses an OBDC-II connector it probably uses the narrow band lambdas already on the car. Worth a go though Ty.

PM me your mobile number mate and I'll give you a call to arrange.

 

Team SWS to the rescue

Many thanks to Tyron aka Cannon Fodder for going out of his way to drop off his VI Monitor earlier this evening.

 

Top bloke Tyron I hope you get the car sorted.

 

Hope the VI monitor helps you solve the problem Dean, Simon RF555 also played a part as well ringing you to give me a call.

At least the VI monitor works on your car as it does not work on mine.

No problem I would do the same for any member of SWS, after all I have had enough favours off other members.

 

If it wasn't for Simon keeping me on the phone talking for ages I'd have not called you Ty

Thanks Simon (RF555)

 

Lucky you're not a glass eye Dean Shame it doesn't work on these JDM's Tyron

 

Well even though the VI Monitor did show the AFR Gauge as a custom gauge on it's screen, it didn't log the narrowband AFR's on a test run .

So I did a little more research and thought I'd give RomRaider a go with my old Seat Leon ODBII cable. Whaddya know, the datalogging worked All I've got to do now is decipher the hooooge CSV log file.

So anyone with a laptop and a suitable ODBII cable for a VAG group car can at least datalog with Rom Raider. Tidy

 

Sorry Dean that the VI monitor did not help, tbh I never used the AFR function to record.

Glad that you have an alternative method of reading the log, before not too long I should have Deltadash which can keep proper logs and diagnostics.

 

Here is a scatter plot of the closed loop afr's only (the open loop data has been filtered out).



Any thoughts on this anyone?
