wideband air/fuel meter

[ALMACK]

I use the AEM brand "Wideband Failsafe" a/f gauge.

In addition to recording the a/f, it logs manifold pressure and samples 20 times per second.

I like the ability to program it to activate the failsafe function if the afr gets too high.

I would recommend the AEM as well. It's priced well and offers much more than just a gauge readout.

How well do you like these? I've got a pyrometer in my car. But it warms up too slow. Does the AEM (or others for that matter) use a 3 or 4 wire sensor ?

The AEM uses the Bosch wideband sensor. It's a 6 wire sensor. It comes with all the wiring and harnesses you need as well as weld bung.

In my opinion it's the best looking gauge as well. The readout is really nice and it's very configurable.

OK, newb asking, can the gauge & sensor be used together without the datalogger ?

[boostedf22c]

Yes.

As Cody posted above, yes it could be used without the data logger.
On the AEM Failsafe, the data logger is built into the gauge.

On my car, I have a toggle switch that turns on the +12V to the Failsafe, and about 4 seconds later it starts logging.
Then after I pass the finish line, I turn the switch off.
Then when I get to the pits I download the run.
It's a nice piece of equipment, and because I run an EFI system with alot of boost and only 4 injectors, I need a device like that for extra insurance.

Here is a pic of my setup within arm's reach while belted up.




This is what the download will look like on the computer :
(It plots one of those yellow blocks 20 times per second)
