Re:diy af meter help
I installed it and it read all the way rich all the time, except when I let off the gas and it's in gear, then only one light is on. I have the pot to adjust resolution, and when I turned it all the way one way 4 or 5 lights were on with 0 throttle in gear and now I have it all the way the other way, is my car just really rich?

I guess that is why they aren't really designed for tuning! Only way to know for sure would be to use a multimeter to test the voltages and make sure your graph is displaying properly. Aren't you still NA? If so, and the graph is correct, I don't think you should be that rich. Well now that I know it works (somewhat), I guess it is time to get my butt in gear and buy some new components so I can start over!

yea that little dot at the corner is #1...
what happened is that right after i power it up, all the LED became kinda dim..then the chip gets real hot and burn off.
so i looked up the diagram of the chip and found out i will have to turn the chip around, so #1 became #10, #9 became #18..

Donald125, What do you mean, they "burn off"? Do they smoke or something, or just stop working??
