Get the Harness. Ls1 Motorsports has them.

The harness enables you to hook up your Rich/Lean gage without cutting any wires. It installs between the factory wiring and the front oxygen sensor. It's really easy. The harness uses OEM connectors and automotive spec wiring.

Default how do you install an A/F gauge? do it yourself?

just wondering if its easy. and how do you do it? I ve heard fuel gauges are hard only because of that attachement to the fuel rails or something likt that... anything difficult similiar to that with an A/F gauge?

I have a write-up on my site for this.

Am I understanding this correctly? You're tapping into the stock O2's to derivate the AFR? I thought one needed a different sensor in the exhaust stream for that...???

Also, so they have digital gauges instead of analog gauges? I'd feel better with the actual AFR numbers.

They do have digital gauges that will tell you exact numbers. I can't remember who makes them though. I didn't want a digital gauge b/c all I care about is that the guages are in or close to the green when I'm using nitrous. It's easier to compare colors than numbers.

jim, the autometer gauge has a sheet telling you in .025 increments per light which one is what.

i have a single gauge and a toggle switch to check between the 2 banks.

How accurate are they? Ive asked a few LS1 people and they all said that the O2s arent accurate enough for it, that it just makes the gauge look like a christmas tree. I can accuracy being an issue via Autotap. The O2s jump around too much.

It's only accurate at WOT.

At part the computer constantly reads then adjusts the A/F. Something like 30x a second. That?s why at part throttle it will jump around a bit.

At WOT it doesn?t adjust the A/F. Everything is kinda preset for maximum power.

it is plenty accurate for me, yes its general, but im only watching mine for yellow, if i see yellow, i back off, if green, its all good <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

not a tuning aid, but ballpark.

Yes there are Digital Display meters on the market:

http://cgi.ebay.com/ebaymotors/ws/eB...tem=1840430088
or
http://www.speedshop.org/
Has anyone used one of these?

I have been thinking about getting one of the square, red backlight ones to put either behind the sun visor or mounted next to my ASR switch in my Hawk. It would be nice being able to adjust MAFT settings and know exactly where you are at for only $70 or so. It looks like it would give at least the air/fuel ratio readings just as well as Autotap would. Where does everyone think that the CPU gets it's information from? The same o2 sensors that you tap into for a meter.
