Monitoring A/F ratio


Inferno

Recommended Posts

Hi folks,

 

I was wondering what options I have to monitor A/F ratios in the Supra? I am running an E-Manage Ultimate and it has an A/F IN option, but I would imagine you need some other device that actually feeds this into the EMU.

 

Does anyone have any recommendations on this?

 

Also, what is involved in setting up a device to rear/monitor this data? (is it as simple as tapping into ECU wires or.... ?)

 

Thanks!

I would think about an AEM UEGO - http://www.aempower.com/ViewCategory.aspx?CategoryID=67

 

A lovely bit of kit. The Sensor goes in your downpipe. Alot of people on here use it and i don't think you'll find any complaints.

 

As James said mate, probably the best gadget around for AFR monitoring. I have one fitted to my J-spec TT, but Phoenix Motorsport did mine for around £250 including fitting.

 

I'm sure you could do it yourself, but no ideas how I'm afraid. :)

Oh yeah the Innovate wideband too - http://www.innovatemotorsports.com/products/xd16.php

 

Very easy, only problem would be the sensor mounting. Your down pipe may have a adaptor already welded on. But i know the AEM one comes with a bung incase you need it. Hole gets cut in the right place, bung welded on and then you can screw the sensor in.
