Default Air/Fuel ratio meter for GC8

Ok, I want to install a air fuel ratio meter in a A-pillar gauge pod on my GC8. It's a MY00, so inherently runs wicked rich, and after the mods I have put on my car, is running more rich, and begining to knock at idle. I want to nip this in the arse before any seriousness becomes of this.

My question is, where is there a good online site to find the gauge and pillar pod, and how to install the gauge, and from there, how to lean the engine out.

Cheers

Will

Well, there's not really any decent A/F meter that's going to fit into a pillar pod, or at least I haven't found any. You don't want to use the stock narrowband A/F meter and you can't use the stock wideband either. Soooo, try looking into wideband DIY kits or products like Motec or FJO (none of which fit into a pillar pod). The reason why I say you need a wideband is because you seem to be looking for measure A/F at all operating ranges, something a narrowband cannot do.

I didn't know that knock is audible at idle.

You dont really need to be rich at idle. Your mid to high rpm when you get on boost thats where you need to be rich.

worth noting the "wideband" gauges there dont include a controler.

Wideband is going to be what you need if you want to do real tuning, but that $30 autometer narrowband will let you know if you're rich or lean... just not how much.

i do have a question pertaining to this subject, i bought a resistor off e-bay it was like 4 bucks so not a big deal if a waste but this guy claimed it added 20 horse to my 98 RS if i were to change the air to fuel ratio now how do i know if i put too much in or too little and im buying a short ram within this week also, as you all already know i do have the annoying MAF on my intake!

Why would you do something that could affect your AFR and not know how much its actually going to affect it?

That aside, you wasted $4. Best case scenario, you get a few added hp. Worst case scenario, you blow your engine. Most likely scenario, the resistor does nothing but help you imagine that there's more power. So go ahead and install the $4 resistor and take a chance. I doubt you'd blow your engine, but it would not be worth it for me to try.

If you could get 20 hp by adding a $4 resistor, then chances are it would be stickied somewhere in this or many other forums telling you to do so.

So ya, spend $300 and get a wideband AFR so when you add your $4 resistor, you at least have a chance of seeing how your car is running and can shut it down before something blows.

Innovate Motorsports LC-1 cable/O2 sensor and gauge combo should do the trick. I bought the LC-1 cable and sensor but went with a vGauges Blue gauge for preference. I am very impressed with the quality of the vGauges gauge. I'm sure the Innovate Motorsports gauge is decent as well.
