Autometer A/F Gauge??
I'm planning on getting an auto meter air fuel gauge. I know it will be NO where near as accurate as a wideband but will it be at least useful to see where Im at right now?? I got the car from someone that suppousely had already remapped the ECU. It seems to be running perfect (maybe a tad rich) but thats the FD normality.
PS: Im also doing it a bit for looks
Appreciate any input THANKS

The only good it will do is to show that you are in closed-loop operation at cruise -- it will bounce around 14.7. Under WOT, it's not even worth having.
The only A/F gauge that's worth anything is the Greddy one because it comes with it's own 4-wire o2 sensor.
Besides, if you have an M2 or Pettit ecu and the "approved" mods, you will be fine. Run it at a dyno with a PROPERLY WORKING wideband setup to verify you're ok.

i have an Apex'i turbo timer with the a/f reading built in...and I find it very useful. Maybe its not accurate, but at least if i know im reading 10.1 under full boost all the time, If i see a 11.2 or 12.1 i know something is wrong.

All I can say to that is my mechanic has tuned his car with the Greddy gauge on the road exclusively. This was with a T-78 and now 99-twins.

Heh, how many miles on the sensor and what face does it have (black, white, or silver)?

I just kind of forgot about it.

I have a DEFI D-gauge for sale.
It is electronic. There is about 2000 miles on it. Black face, amber backlite, so it is close to the stock gauges in look.
I'll take 100 shipped.
