#47697, "Ok... it's time for the A/F gauge."




          

Sup guys.... I just finished installing the EGT gauge and the boost gauge yesterday. Even thou I haven't have my turbo in my car yet...but I am starting to work. And the main reason is I am waiting for the Exhaust Manifold from Gottude.com. I hope I will get that in the coming 6 weeks.

BTW Motofool, did you sent out the SFMU and the oil line kit yet? It's been 3 weeks. Thanks man. Just hit me a few words about it.

Anyway, For the A/F gauge:
I have the 1995 GS Mitsubishi Eclipse...and I want to konw where I connect the cable to for the A/F gauge.
Questions:
1) I am planning to make my own A/F gauge which will built into the speedometer and Tach meter gauges, So how many wire for obtaining the A/F data??? 2wires? 3 wires?
2) Where is it connected to? all the way to the O2 sensor? or tap to the ECU? and where? which pin and cable. (and so on..please more detail)
3) Finally, if I read from the pin or sensor.. is it already in Voltage form? from 0 to 1V? Thanks alot guys!

Any input and sugguestion will be appreciated.

Any other input?? Come on guys. give me more info!
For making the A/F gauge, I am perfectly comfortable with it. But my main question is, which pin I have to connect my A/F gauge to? to the ECU? or what?

Also, Motofoo I will prolly call you tomorrow to ask you about the SFMU. If you can, just reply me here with it's update! Thx!

Anyway.. any input will be greatly apprecaited guys!

Look for a white wire with a black stripe on the upper ecu wire harness. Thats the wire your looking for.

Okay the Top harness of the ECU has 2 wires you need. You need to tap into the white wire with the black stripe for your O2 signal and the larger wire in the harness which is black with a red stripe which is the ECU power and you want to use this for the Digital A/F gauge power. The ground needs to be a good ground because if you have a bad ground you will get incorrect readings.
