Default Honda Wideband Question

I remember hearing that the Civic VX I believe it was came from the factory w/ a Wideband 02 senor correct? When using ECU Control, can I just get one of those instead of buying a L-2? If I'm running ECUControl, there is no reason for me to have the "Display box" with the L2.

Am I missing anything here?

The VX does have a wideband 02 sensor in, but thats all it is, just the sensor, You still need something to convert the signal into numbers, like the L-2.

You cant just hook up a Wideband and go with out any type of controller.

A WB operates and sends a 0-5 volt signal. A stock O2 operates on a 0-1 volt signal.

Why do you think WB's are expensive, its the ciruitry and the programming of the controller that is most critical.

ECU Control is a program...you dont hook a wideband up to it

How does ECU Control read A/F than if I don't hook up the Wideband O2 into the ECU?

BTW: We bought a LM-1 today for 250.

If you are using a VX ecu, and the stock wideband sensor is in place, then your a/f readings through ecu control should be much more accurate (because of the wideband) than the average setup that isn't using a wideband. But this is only because the VX ecu has the circuitry built in to control the wideband sensor. You can't use a non-vx ecu with a vx wideband sensor; the ecu is expecting to see 0-1 v when the sensor is putting out 0-5 volts, not to mention the sensor won't even work without the heater circuit, etc.

Is this on a OBD0 or OBD1 ECU?

If its OBD0, you cant...it will flip the ECU out.

If it's OBD1, Uberdata or Crome can now accept a 0-5v signal into the ECU. Your LM-1 can output 2 O2 signals at once and they can be either 0-1v or 0-5v or both the same.

Hm. Ok I guess I just don't understand why ECUControl is setup for A/F when you can't get it to work. It is an ODB0 ECU (PM6)

It reads the stock narrowband O2 output...which is literally useless for tuning purposes.

Basically the best use for EC is for map trace and soon RTP.

Look at the wideband and then look at EC to see which CELs your car is running from and edit accordingly.
