What gauge are you using and Are you using a stock narrow band O2 Sensor or an aftermarket Wide band O2?
If your using an AFR gauge with a stock narrow band O2 sensor you will only ever get narrow band AFRs. It will either show rich or lean on the gauge due to the O2 sensors 0.5 to 1v signal output (aka narrow band). A wide band O2 sensor signal usually ranges from 0.5v - 4.5, 5.0v (AKA wide band) This is how you get a wider verity of AFRs showing on the gauge.

If you don't understand what he's saying is that most likely your gauge reads from the .5 to 4.5V so if it gets a signal other than that or a lower signal from the stock O2 sensor it will not report it properly.
Same thing with computer chips and all that, they have acceptable ranges and if you don't get in there you get odd results

That thread is very missleading for a noob. It does have some good information but it's mixed in with alot of BS.

WoW is all I have to say about what 97ekb18b was promoting in that thread. Runing an autometer narrowband AFR gauge on an untuned car is not cool at all. Specialy runing 24lbs of boost. F'n retard.

Haha I just read bits and pieces, namely the bit about connection the gauge. Did not see that part you were talking about

If you do not have a wide band O2 sensor and wideband gauge don't waste your time or money. The narrow band Autometer gauges are really just for show, in conjunction with a narrow band O2 they don't have a wide enough range to be of any practical use.
If you want a real AFR gauge you are going to have to spend some money. Do some reasearch into these brands.
Innovate LC-1 - XD-16 combo or LM-2 Kit
PLX - DM-200 + SM-AFR Combo
AEM - Single Channel Wideband UEGO Controller Module
And there are a couple cheaper DIY-WB kits out there as well.
If you are comfortable with reading electronics schematics & soldering.
After all this if you still want to throw a NB gauge in there, It will come with installation instructions and it will not affect your computer. Unless you wire it wrong.
