Logging with Wideband

[02SSLE]

Hey guys I have a Autometer wide band and I am needing help setting it up. EFI live isn't setup to be able to use this wide band. Can someone help me. I am new at this just trying to learn. Any help much appreciative.


Thanks

As per Autometer's web page, their wide band meter has a 0-4 volt output. You would need to find out what air fuel ratio is at what voltage. Then put the formula into EFI_Live calc_pids.txt.

can anyone else help me with this? does anyone know the volt out put?

So based on autometers specs 0-4v and 10-20 afr should be a formula of:

2.5*V+10 ??? And if so what would that pid look like??

[02SSLE]

surely someone knows how to do this.

2.5*V+10 is correct based on Rhino's post.

See attached calc_pids.txt file.

02SSLE,

Take the calc_pids.txt file from post #6 and copy it to the folder: My Documents\EFILive\V7.5\User Configuration

Cheers,
Joe

So I guess all I need to do now is hook up the two wires that I ran from the wideband to the V2 controller?

[joecar]

Yes, connect:

• signal wire to AD1+
• signal return wire to AD1-

Look on the decal on the back of your V2 to see which pins are AD1+/-.

If you use AD1, then your pids are CALC.AFR_WB1 and CALC.BEN_WB1.
