Quote: why not get a lean/rich gauge and single wire O2 sensor? Tom used one to setup his blower motor and I used one to tune my Dominator.
They work ok for simple tuning at idle and such...but they have limitations. Slower to react....and you cannot datalog and graph along with RPM throught the run to evaluate your complete fuel curve. Even a wideband isn't all that useful in my opinion without the RPM info to coinside with it.
All my wideband use has been on my brothers chassis dyno though...but now that he's renting dyno time again...I would like my own wideband setup.
