Does timing affect air-fuel ratio?
Correctly timed ignition will cause peak cylinder pressures to occur around 12 to 15 degrees after TDC. If the peak cylinder pressure is reached too early, power will be lost as the piston fights to compress the burning air/fuel mixture.
Where to hook up air fuel ratio gauge?
Route the wires through the firewall hole in the dash. If there is no hole in the firewall, make a small hole in the firewall of the vehicle so that you can route the wires of the gauge into the engine bay.
How do you connect an O2 sensor to a fuel gauge?

Run these wires behind the driver’s side valve cover, down the back of the engine towards your exhaust system. Be very carefully to avoid parts that get hot. The goal is to get the wiring as flush with the firewall as possible. 20.
How does the Auto meter air / fuel gauge work?
The Auto Meter Air/Fuel gauge has a signal output for supplying information to a Data Logger or engine management system. The signal provided is a linear 0-4 volts output. 0 volts out equals 10.0 Air/Fuel Ratio, 4 volts out equals 18.0 Air/Fuel Ratio. Note: Due to the limitations of the sensor, the indicated Air/Fuel Ratio
How do you install a fuel gauge on a car?
With the grommet removed, carefully cut an ‘X’ in the center of the grommet using the razor knife. 25. Route the wiring for the Air/Fuel gauge through the grommet, into the firewall, as shown. 26. Pull the excess wire inside the car, and secure the wiring under the hood with zip ties.
