So I hear they produce A/F gauges that are actually accurate now? I haven't seen one nor do I know where to go to find out about them. Have any of you ever heard of one or possibly own one?

Since my turbo for the VR is all plug and play I';d like to have an accurate readout of my A/F ratio.

 

the only worthwhile air/fuel metering gauge is a wideband. it gives you an actual number, not a blinking light

 

the greddy full sweep joint is hot, very nice air fuel guage,and very accurate since it comes with a wideband.......

 

AEM

 

I concur with Ricky. But damn I wish DEFI would make a A/F gauge for their BF series. I want to run those when I finalize my turbo kit.

 

I love my Greddy Wideband A/F Gauge! Its accurate & great for tuning.

 

Yeah the AEM uesomthingoranother is a wideband and is pretty accurate. the greddy is SEXY also. all u need then is a boost and egt and gauge and ur set

 

PLX makes a 50mm round wideband gauge also, it's a little basic looking but has a dual readout, both numeric and sweep-LED. It hooks up to any of their M series controllers I think, which is cool because then you can have a wideband O2, with a wideband gauge, and a narrowband output to feed the ECU.

I'll take the numeric display over the analog Greddy any day, it's easier to read and quickly interpret for tuning.

 

plx also makes a wideband conversion for narrowband A/F gauges, but you have to have the M series controller. i think its like $40 shipped.

Yeah, but then you're at the mercy of the noise and accuracy problems of a narrowband gauge..
