Setting up Wideband commander with hptuners

[silverzz28]

Since my tuner has bailed on me I need to finish tuning my car. I have a wideband commander in the car. I dont have the pro version of hptuners but I was told you can wire this wideband into the pcm(01 fbody) input for logging? I dont see in direct info on this. Anyone??

There are a lot of write ups on how to do this. You can either use the A/C Pressure sensor or the EGR plug. But with your car being a 01, if it has an LS6 intake you will have to add the wire to the pcm for the EGR.

Here's a good write up: http://ls1tech.com/forums/pcm-diagno...thout-eio.html

In the scanner table make sure you are logging AC Pressure and AFR Commanded for the PID's to work (if you do decide to use the AC Pressure wiring).

Thanks. I still have my ac but I guess I can use it for tuning. Also I have a wideband commander with output leads.

Use the EGR then. Since your car is a 01' (I don't think it has the wiring for the EGR), take one of the outputs on your wideband and run it to the EGR pin on the PCM. Then setup your scanner to log EGR, create the custom PID for EGR and the wideband. Pretty simple setup.

The EGR PID is 2810 and 2811. Whats the range of the wideband commander?

Quoted from 5_liter_eater :

"volts / (voltage range/Device range) + (Minimum value of device range)=AFR

This breaks down as follows:
Volts = Incoming voltage reading, typically between 0-5 VDC.
Voltage Range = Range of sensor, typically 5
Device Range = Range of AFR that your instrument is set to read. Minimum device range = Lowest AFR reading of device. In the example above it is 10.

Using the numbers above, the formula would read as follows:
EGR volts/(5/10)+10
or
volts/(.5) +10 <--play with the 10 value to get HPT to jive with the gauge or logworks."

If you get the range I can help setup the scanner for you.

0-5v on the wbc. I suppose I need to turn the egr on in the tune?

Yes, you will need to enable the EGR in your tune.

Thanks I have it on and its reading in charts. I'm having a hard time getting it to work in the Histograms. Ive looked for a custom config files but no luck
