Ok so my problem is that my wideband is working fine but my haltech is only reading it as a 0-1v signal.

Heres what I have done so far.

checked the output on the FJO and insured it is putting out a 5v signal to the haltech. checked voltage again with haltech hooked up and both units on voltage went from5.00 to 4.99 so im not "loading down the signal"

checked the haltech settings for the O2

sensor type is bosch
volt range set to wideband 0-5v

I attempted to change my threshold to what a wideband would run for stoich but it wont allow for values of 0-5v my understandinv is a millivolt is .001 of a volt so in theory 2 volts would be 2.000 millivolts ot 2000 on the haltech. the haltech stops at 1001. is this normal and just the limitations of the e6k or is it just that the haltech manual is SO lacking that it doesnt tell me what is necessary to read a wideband?

My manual basically says it can use a wideband and stops there.

am I using the wrong wire for 0-5v? im using the standard o2 grey sheilded with a light green wire inside. according to my diagram in the manual that is correct but it doesn specify signal voltage range.

Thanks for the help.

 

I had to use the spare ad on a aem unit. It can only be used for data log. I dont know if its the same for you but someone will know the answer.

 

maybee this will make more sense then above. i pulled this from what i wrote on a duplicate thread by mystake.

Ok so I cant get a 0-5 volt reading on my haltech.

I made sure the FJO was properly configured and that it was outputting a 0-5v signal with my multimeter.

Hooked up haltech to check for any loading down of the signal and the voltage stays the same so i believe my FJO to be fine.

Went in haltech setup verified that wideband 0-5v was selected.
bosch for senseor type also selected.
still only reads a 0-1v signal in datalogging.

I attempted to change my target ranges and it wont let me put anything higher then 1001mv or 1 volt.

What am I doing wrong here? is there some other wire I need to be running this through?

any help appreciated.

my FJO is a 30001 series btw

 

Try setting it so it just reads the 0-5v range, make the sensor standard (or wideband, doesnt matter) and dont have your engine datapage opened when you do these changes.

See if the input reads the 0-5v signal. If not, use the Spare A/D set to general, it should read what ever you feed into it. Then when you do datalogs on what ever input you use, you can use Excel to convert the voltage to AFR using your unit's formula, probably found on the documentation.
