I bought this from ebay at the weekend and its due here soon. Im looking at installing it myself but i am wanting to know how easy/hard it is or is it worth putting into a garage to done?

comes as a complete kit

 

◦Comes with inter-changeable facias as shown below

◦Ideal AFR monitoring tool for EFI and carbureted applications

◦Does not oscillate AFR reading like narrow band sensors

◦No laptop required for monitoring

◦Bosch sensor included

◦Accurate to 0.1 AFR

◦Reads in AFR or Lambda via a switch in back of gauge housing

◦24 Color-coded LED display lights provide immediate reference to engine’s air/fuel ratio (AFR) or Lambda ratio

◦Integrated three-digit display reveals AFR or Lambda in real time

◦User-programmable 0-5v analog output included for use with data loggers and virtually any engine management system

◦Serial data stream included for output of AFR (RS 232)

◦Weld-in exhaust boss included

where about on the first cat does it need welded? how do you run it from the cat to the guage :blink:

 

Wherever you like, at 90 degrees would probably be best for ground clearance issues.

 

The wire goes in through the firewall, easiest place is the drivers side below the brake booster in the inner wing.

ill wait till its here and get some pics up lol

 

Don't really need pics, they are all the same.

 

There will be the wideband sensor which screws into the weld on bung. There will be the wideband logger/controller which will directly connect to both the sensor and the gauge and there will be the gauge itself. The gauge will need wired into the ignition, battery positive, earth and possibly the lights.

 

Job done.

okay scott very funny.

of corse i have not wired it straight to perminent feed its off a switched live, i was just stating what the unit needs

 

You don't have a clue what you are talking about though. You can't just tell a guy how to do something that you don't even know how to do.

 

Do you have an AFR gauge? Did you fit it? If so I would take it to someone to get it fitted properly and then re-calibrated as if you fitted it via your patented 2 wire method then your calibration is all to pot as the memory is erased everytime you turn the ignition off.

Also it will be 3 wires, possibly 4, rather than 2. You will have at least Earth, Ign +ive and Battery +ive. You will most likely also have a dimmer for when your lights are on.

 

Scott, I just installed mine recently, it is has 4 wires, earth, power, output for RS232 cable and 5V output..

 

I got it connected to a switched live as I dont want it on when the car is not running.. It does not have memory, the calibration is set by a switch on the rear...

Apologies mate, I stand corrected.

 

I must say that it doesn't sound like a very good bit of kit in that case. For a start the reason for an ignition live and a battery live in every gauge I have seen/installed is to keep the current draw at an absolute minimum from the ignition. It is neither fused nor gauged for anything other than switching. Sounds like a massive howler from AEM IMO. I would be selling it and buying a decent one.
