no man , a wideband has multiple wires running into the guage.. like 7 actually.... what your talking about is not a wideband, but a narrowband afr guage... if it dosent read in #s
its not a wideband... widebands read out a number from 10.0-17.0 with 14.7 being stiometric,
or the perfect afr of 14.7-1 .... anything below 14.7 is rich, and anything above is lean.. on a turbo car to be safe.. the car should not get any leaner than a 13.6 at any point in the rpm range... to be safe most people keep em in the 12s afr... and once you are used to the numbering system you will be able to tell at a glance what your engine is doing...
the ecu will keep you in the safe afr with anything 16psi of boost or lower above that tuning can be achieved with a adjustable fuel pressure regulator...
