Chaps...
If I have an AFR meter, do I really need a knocklink as well? 17PSI with a Dawes. (UKMY'99) Just thought that If i am running ok I should not knock James. |
Hi James,
the afr tells you the mixture of fuel/air, the knock detector tells you of ANY noises inside the engine, be it knock, whine etc a different kettle of fish and a highly useful one if you want any advance warning of any noises which could lead to large bills. Peter. |
Thanks Pete
AFR is an alternative to Lambda Link AFAIK, hence the reason I chose an AFR gauge over a Lambdalink, and still have my Knocklink fitted :) Steve |
Just fitting an AFR can you tell me what wire on the ECU I should connect to.
Thanks John |
Please
|
Not fitted mine yet, this weekend all being well :)

James,
As I understand it, the fact that your AFR readings are ok does not mean that your engine might not be detonating due to overboost and/or ignition advance. That is why you need a Knocklink as well. Les :) |
Help,
what wire where for my mVolt pickup for the AFR Voltage? I have two white and one black wire from the exhaust sensor. UK MY'99. (I'd rather pick up at the ECU if I knew where it was. James. |
James
I picked mine up from the ECU Blue Connector B136, pin 21 White with Silver dots :) mine is a MY00, and as Im running a MY99 ECU it should be the same Steve |
Thnks Mate.
|
Bugger,
There is more than one white wire with silver dots. How do the numbers count on the connector? James |
I think its the 3rd row down, 3rd one in I think
there is a thread on here with the pic, Ill see if i can find it, its defo 3rd one down tho Steve |
Sonic,
I found the thread, and wired the baby up. :) Tell me, does everyones AFR flash up and down when on the cruise, and only display a sensible reading once you floor the throttle (like three green lED's lit). If i blip the throttle when standing still, it hovers around the green only to eventually turn off completely when the engine idles again. When I first turn on the ignition, the first LED (green) lights until I start the engine. Is this correct operation? Thanks, James. |
Wish mine did that :(
basically yep thats right what yours is doing, mine however does do as yours does, till I get to about 4k rpm, then it drops straight round to lean, then off, and then stays off till im idling again |
Oh err.
Thanks for the replies though. |
It does worry me a little with these guages that if we pull the Voltage from the sender down (with the AFR) that the ECU might not be reading correctly.
|
Thanks
Got a pinout from a helpful guy on here Better change my username ? :confused: |
