Afr Gauge

[mark61]

Hi all

Hooked up my afr gauge yesterday and to say the least am a bit disapointed

First up hooked it up to the grey wire and nothing happened but a few LEDs on the lean side 'nothing else'.Swapped the wire to the black and had the full gammit of LEDs from lean through stoich to rich and thought all is well.

Took the car for a long run today and all the gauge does is wind around from lean to rich never staying in one place long enough to tell what is happening.

Is this all it is supposed to do as I thought that you should have got the LEDs to stay in the stoich while cruising then while under exceleration go to rich ect .

Can anyone tell me if theirs does this as I am thinkihg of trying the white wire to see if it makes any diference

That's all they do.... just provide some pretty lights for you to look at.

If you want a useful AFR gauge, you need to install a wide-band Lambda (O2) sensor and associated display.

There's a bit more cost involved though.

When the AFR guage cycles from lean to rich in a dancing motion it means that the ECU is running closed loop. Its a normal function.

mine does exactly the same mate. You'll find though, it should stay in the "rich" area when you put the foot down and are giving it WOT.

It's just a very rough guide..

A bit piss week. Should of gone for something with a needle read out. Fell for the shiny lights again

Its actually quite useful, tells you if your car is running closed loop, tells you if your car is running correctly (I.e rich under WOT) if you were running lean under WOT you know you got problems

Sorry Mark aparently in the BF it's the black wire in my BA it's the grey. They are useless to say the least but here's are some that give you the digital A/F, not cheap though.

Invest in one of these

to increase the accuracy of this guage IE , one LED at a time compared to about 3-4 LEDS , run the earth for the guage back to the O2 sensor low (for BA its the grey with pink stripe , and watch the difference in guage behavior! way more accurate!

Do you know which wire in the BF as they seem to be different as I would like to try it
