couple of AFR and AFR Gauge related questions
Hello all,
I've recently fitted an AEM AFR gauge and boost gauge.
I took it out for its first drive since and I was wondering if an AFR of 13-14's at WOT is ok? Or is that too lean?
Should I be worried? (bearing in mind I've been running the car like this for months and I've only just fitted an AFR gauge)
When cruising with very little throttle its showing 11-12's is this OK? And at middle-ish throttle the AFRs seem to go all over the place but I'm guessing that's because there is no real "map" to speak of.
Last question is the boost gauge seems to show a lot of vacuum at idle? Like 20 mhg (or whatever the measurement is!)
Any help is greatly appreciated!
Stix!
11-12 when cruising on light throttle is too rich, should be about 14-15 at that point.
13-14 isnt terrible at full throttle, should be a little richer but will be fine.
as for the boost gauge do you mean 20 cmhg? if so its fine, should go lower when lifting off throttle.
Buy a what?
Afaik the greddy has an input plug for map sensor etc doesn't it? Think it's the 2 outside wires. One needs earth one the 0-5v output from the aem.
Just open the ecu and solder wires to the pins the plug connects to. Much cheaper option.
£30 for a plug and 2 wires though. each to their own i suppose lol
