Analog wideband help for new starters

[braapp]

Nar mate i just had it hooked up to the v2 alone and thought it may give me a read out, can you see the voltages in the data screen with the car running? On the wo2 screen it still dosnt recognise the wideband.

you won't see wbo2 data on the v2 screen unless it connected via serial.

analog voltages should be displayed with passthru.

Ok my current wideband ( haltech dual ) isn't serial capable, do i select external wideband pid in v7 passthru and will it work see i don't really know all i seem to be getting here is what I'm doing wrong. I was hopping this thread would help me and others so far it is confusing.

[mr.prick]

what model do you have?

HWC, HDWC, HT059970 / HT059980

[braapp]

Its the old style dual HDWC ( I'm only using it as a single ) not the new one with the CAN capabilities to integrate with a haltech computer.

[mr.prick]

not the lc-1 clone.

signal wire #1 (white) connected to AD1+
signal wire #2 (grey) connected to AD2+

[braapp]

Not sure what you mean by not the lc-1 clone the signal wires for the haltech are white and blue.

What about the ground wire...?

With the wideband wired up to the V2's external input AD1, log the pid EXT.AD1 - this will give you the widebands output voltage.
Then you need to log a calculated pid that will convert the voltage to an AFR that you can relate to. Log CALC.PLX1 (PLX uses the 2v+10 equation that I believe Haltech also uses for converting voltage to AFR) - now you will have AFR in your log too.
From there you can use the CALC.BEN_PLX1 for your correction factor.

The above values assume stoich is 14.7 - which is ok for pure gasoline - working in EQR/lamba is better but requires some changes to the calc pids that can wait until you're up and running.

Thanks Darcy this has sort of been what I've been after all along cheers. Can these pids be found in the v7 list.
