I got a WBo2 (LC-1) and was wondering what voltage the ECM (730) is looking for? The output is programable and the factory default sets 14.7AFR to 2.5 volts and I know it should be < 1v, help please?

A WBO2 reads lean at higher voltages. A NBO2 reads rich at higher voltages. They are inverted. If you use a 730 ECM code patch then you can read the WBO2 and correlate it with the other ALDL data. You can't use the WBO2 sensor controller output into the 730 ECM WBO2 input. You need to use a simulated NBO2 from the WBO2 to do that.

I don't use an LC-1, but I believe it has a NBO2 simulated output (0 - 1v) that you can connect to the stock 730 ECM NBO2 input. In order to read the WBO2 output AFR (not simulated), you need a code patch that dumps the WBO2 reading to the ALDL datastream. What mask / bin are you using? A code patch may be available.

The LC-1 has a simulated output (factory default is output 1) and is programmable to use with all different types of ECM's and dataloggers, the only one they can't simulate is an o2 that changes resistance. I'm not rally fimiliar with tuning the stock prom and MS is in the mail but I wanted to use this WBo2 so I can use their software and log the o2.

For the 730 ECM, you can disconnect the stock NBO2 sensor and plug in the LC-1 simulated NBO2 output into the 730 ECM where the stock NBO2 plugged in. That will allow the ECM to run the fuel off of the WBO2 sensor. Nothing is to be gained by that except for entering closed loop quicker.

As for seeing the actual AFR from the WBO2 (the good output...not simulated NBO2) you are out of luck unless you use a 730 ECM bin code patch. The code patch will read the WBO2 on another ECM input that was not used by the factory (MAP2, TPS2) and spit out the AFR on the ALDL datastream. It requires a 730 bin code patch and a custom ALDL datastream file. This is how I do it.

As for the MS, you can connect the WBO2 output (not simulated) to the MS and get the MS to use the good AFR for fueling and report to the laptop computer. That is done through the setup interface. Much easier than using a 730 ECM with a code patch.

EDIT: Did you mean log the real WBO2 AFR with "their" (Innovative) software? If that is the case, then connect the simulated output to the stock 730 ECM connection and read the real WBO2 output via innovative's software.
