View Full Version : Gauge AFR Help?

Just fitted my AFR (air / fuel ratio ) gauge, hooked it upto the relevent cable on the lamba sensor.

Car starts fine etc no problems there, but the gauge just stays on 1 light lit for lean?

Is there like a certain amount of time you need to wait before it works properly like let your car get to optimum temperature etc??

If its any help, i got a saxo vtr mk1

thanks.

Whats one of those then mate?
You got a picture of it?
Sorry i'm of no help, i can't really make that out - All wires connected up properly? could be a connection maybe?

Have done, pritty sure he has a seperate lambda sensor tho for his, im running off the standard one spliced in on the loom.

i replyed to this in the other thread in the engines section aswell. The thing with afr meters is they dont like to be hooked up to a lambda thats being used by the engine ecu as it can get interference on both sides to the guage and to the engine ecu. for best setup u should realy be fitting a second lambda sensor and using that to take a reading. one posibility is that the guage might not be working correctly so u could test the lambda sensor using an oscilloscope to see what signal its putting out. as a rough guide most lambda sensors read 0.8 to 0.9 volts when air/fuel is rich, 0.1 to 0.3 volts when the air/fuel is lean. when idling it will be oscillating between lean and rich.

get a de-cat for a mk2 vts, they have a lambda sensor hole in it, fit another lambda sensor there then wire the AFR to that ;)

i never got round to fitting mine, but thats all i was going to do ;)

Yeah like Boz Said.
Or if you're running 2x Llamdas anyway, you could disconnect one of them and use it solely for the AFR Guage.
