has anyone put a a/f in there ep3 and if so what did you use for your pwr ground and a/f input

 

put a a/f in there ep3


???????????

 

AIR FURL RATIO GAUGE

 

fuel

 

well should be same thing as typeS. run a power/gnd pair from cigarette lighter or interior fusebox. signal wire goes to ECU.

if you tap the primary sensor, hondata says you can screw yer ECU since it's the same wideband that the ECU uses to maintain your 14.7 AF ratio in closed loop.

if you tap the secondary sensor, you'll only receive the gauge flipping back and forth since the secondary is a narrowband sensor

 

what wire is it on the ecu do you know

 

The ECU is located under the glove box. All you have to do is take the cover off from under the glove box remove the 2 10mm bolts on the sides, open the glove box remove the two stoppers one on each side, remove the last 10mm bolt on the top of the ECU, close the glove box slide the ecu down, now to connect the wire there are 3 connectors from the ecu, the one on the left with a white base has 31pins take that one off, there should be a white wire with a red stripe on it, tap into that wire as that is the signal wire from the secondary o2 sensor. then reassemble ever ything and your done.

 

help was greatly appreciated what would i do with out honda tech and one less holw in the firewall
