e6k reads different A/F than my gauge?
im using the software e6k34U which reads A/F readings....i have the wideband hooked up VIA spare AD and set to uego air fuel. it reads the wideband but its reading different than my gauge?
im using this setup:
http://www.innovatemotorsports.com/x...babc85608ca373
for example:
e6k reads 14:
gauge reads 12:-13:
anyone have any idea whats going on or what i could check?
i hooked this all up myself so if anymore info is needed please let me know.

Did you calibrate the output from the Innovate to suit what the E6K is set up for? If you're using the Innovate version of the wideband you will have to calibrate the output. The E6K is set up for 0v=10.0afr and 5v=20.0afr. The Innovate #2 output is setup 0v=7.35afr and 5v=22afr if I'm not mistaken.
Also make sure you don't have any ground offsets.

i found this searching...

Most modern standalone Engine Control Units can benefit from the use of a wideband Air/Fuel meter. A few of the basic applications are closed-loop EFI operation, tuning and setup, and narrow-band emulation.
Closed-loop EFI operation.In this application, the wideband controller (LM-1, etc.) controls the wideband oxygen sensor, and outputs a 0-5V signal that continuously informs the ECU what the measured air/fuel ratio is. The trick is to match the voltage-to-AFR correlation so that it is mapped correctly to the ECU. All Innovate wideband controllers have programmable analog outputs, so often it is as simple as determining what the ECU is “looking for,” and programming the LM-1 to match it. Innovate digital wideband outputs are truly linear, and many older analog controllers are non-linear, so, in some cases, you’ll need to reprogram the ECU’s input table to match the Innovate output.

and since i connected the ANALOG 2 to the spare AD i connceted the LC-1 ground to the spare AD ground.
ill try it in the morning and report back.
and BTW:
thanks!! your the freakin man!! this was driving me crazy!
