Air/Fuel Ratio Gauge - Third Generation F-Body Message Boards

StocRoc · 03-12-2002, 04:40 PM

I am going to install an air/fuel ratio gauge once my procharger goes in. Is there any certain brand that is better than the other, or one that sucks?? Which do you guys run? Thanks

Check out the DIY PROM board. They have a very accurate Air/Fuel meter than. Better than anything I ever heard off.

Keep in mind that any gauge combo sold for under $250 will be for the narrow-band air/fuel meter. It's basically a rich-lean indicator. Above 500mV, rich, below 500mV=lean. Folks try to tune with them (i.e. blah blah said I need to keep it at 890mV), but they aren't to accurate. It is better than nothing, though. If you can buy or borrow a wide-band air/fuel meter for when you need tuning, it's a much better solution. You can buy them complete starting around $700, or build a kit the DIY_EFI folks have been kind enough to put together for about $35+sensor (around $125-$150). HTH!

Thanks for the help guys. I will check into building my own, sounds like a pretty good deal.

Just go to pep boys and buy a stock O2 sensor for a civic. 2 black wires = positive and negative, 1 white wire = Guage wire. Attach that guage wire to a $40.00 Auto-Meter Stoichiometry guage.
Then take the header / Y-pipe / Manifold to a muffler shop and have them weld it in for $12.00. or do it yourself...
Bingo, done and done, under $75.00

Want more info? email me.

Take a look at http://www.diy-wb.com/. It will cost a about $160, but it will read way better than a regular O2. Especially at WOT, which regular O2 does a terrible job.

i have the autometer ultra-lite air/fuel ratio gauge, i reads in 50mv increments from 50mv to 1 volt.
it seems to read fairly accurate or atleast as accurate as my AUTO X-RAY

later

my 1st was a cyberdyne (called intellitronix back then) and I still love'em, have one NIB for my project, but I saw this new one by a company called "Nordskog" (formerly cyberdyne) and it is analog face and has a microprocessor that buffers the imputs to raise the accuracy? the older intellitronix/cyberdyne/nodskog gauge (#n7009) is like $30 and the fancy one is like $139? they both will hook to your stock O2 sensor with no ill effect. I'm a info freak so I'm considering a pyrometer also. hers the fancy one http://www.intellitronix.com/d70140prfanlg.html
