Ok, can the PFC measure the voltage of the O2 sensor and more importantly WHERE DO I SEE THIS?

Also...
Instead of someone saying "look in this link" can someone be more specific on which map would I need for the following setup...

Big street port
Flywheel
Pettit Intake
DP
MP
Catback
Power Pulley
Supra Fuel pump
Stock IC
Stock Injectors.

Thanks

BAD ***!!!!!!! THANKS A ZILLION!!!

now what's normal reading...?

 

Normal?? Mine reads from .01 to .05 at idle warmed up and depending on engine load. Under closed loop driving; from .1s to .7 depending on speed, 0 to 80mph. Under boost, .85 to .9.

 

The o2 reading on the power fc does not mean anything. The o2 reading also depends on the exhaust temperature. In fact, the positon of our o2 sensor is too close to the exhaust source. It should be farther down the pipe. Right now I have a T51R kai turbo and I also use the Greddy A/F gauge. I put the Greddy oxygen sensor at the original oxygen sensor bun on the HKS downipe. The Greddy a/f meter has a over heating warning feature. If the exhaust temperature is more than 800 C, the warning light will be flashing. When the sensor overheats, the reading is not accurate. Mine over heats the whole time even though just cruising on the freeway. If you really want to use that, I would suggest you to put the oxygen sensor farther down toward the end of your downpipe. My power fc reading at full thrttle is 1.2 V. I put my car on the dyno and use the wide band lambda sensor, the a/f ratio is 11-11.5. Now can you depend on the power fc reading?

Is this just a drop-in replacement for the stock O2 sensor? Will using a lambda sensor help the Apex Power FC and tuning to the proper AFRs?

Where do I buy a lambdo O2 sensor, and how much?

 

Manny,

A WB O2 sensor (aka Lambda) is not going to do you any good unless you have the heater and circuits to run it. That is where the TechEdge and FJO Wideband kits come in. They package the required hardware to provide the AFR readings.

I suggest highly that a new bung be added for tuning, and it is positioned not greater than 3-4' of the output of the (last) turbo.

What is the FJO wide band kit?

I'm a newbie to all this stuff, can you tell ?

 

Hey Manny,

Do a search! Lol!

FJO and Techedge are two companies offering fairly inexpensive wideband O2 monitoring kits.

Chuck Westbrook posted this link for $36 direct replacement oxygen sensor. I was just wanting to replace the old O-2 sensor with a brand new one, so the Apex Power FC is getting decent AFR data??

None of these wideband oxygen sensore will hook up to the stock engine harness, and so the Power FC won't be able to do read the data from the lambda sensor?
