Is there anything else out there worth purchasing , other than the innovate lm-2 ????? thanks ,pat

Bear in mind that if you have a "perfect" 14.7:1 a.f.r. at cruise, you'll probably have a few lean and rich cylinders somewhere. I got to the high 13's at cruise and called it good enough. I have my o2 sensor mounted 12" from the turbine outlet, so I know all the exhaust is thoroughly mixed by then.

If you are running 10% ethanol pump gas your ideal AFR is 14.1 to 1.

While that may be technically true you can only use that info IF your wideband system is SET with a 14.1:1 stoich value. If your system is set to display gasoline stoich of 14.7:1 you can still use 14.7 as a stoich value when reading the numbers displayed regardless what fuel you're using.
Wideband systems measure oxygen presence and produce a variable numerical output value represented by the Greek letter Lambda. The value for Lambda at stoichiometry is 1.00. If the wideband system user sets the device to display s stoichiometry value of 14.7 (or any other number) the device simply multiplies Lambda by 14.7 (or whatever number is used). This does not change anything about how the device makes the measurement and the device does not care what fuel is being used.
Whoever created that chart was well-meaning and technically correct but has created a communication nightmare where now people can't disuss AFRs without stating what stoich value the reading was taken with (and requiring math to convert to ones familiar scale). It would be much better if everyone just used Lambda (1.00) or 14.7, regardless what fuel is being used. The wideband system doesn't know or care.

Finally got the Innovate Wideband 02 in AND working properly.
Took it out for its 1st drive.
Idle 13.5--14.5
Cruise 11.7--12.2 rich
Power 13.5 steady too lean.

So now the chase begins.
Max power is pretty easy to fix,cruise may be more of a challenge.

I'm going to assume when you say power you mean at W.O.T., if not what do you mean? Your idle AFR are good, I do run my pump gas motor leaner than that, 14.8 to 16.0 depending on outside air temps as far as cruise I like an duse real close to 13.8 to 15.0, WOT I shoot for 12.8 to 13.3, not the best for a boosted motor so I would shoot for 12.2 to maybe as lean as 12.8, depending on what the spark plugs look like( all eight plugs) It is way safer to start out rich and then slowly lean it down to where you like it The transition circuits are real fun to tune

The wideband <oxygen> system doesn't know or care.

That is the beauty of the wide band oxygen sensor system.
I have used my wide band oxygen sensor with race gasoline, alky (methanol) and E-85 ethanol. It measures Lambda, I typically display A/F based on 14.7 (gasoline) since those numbers are in my head. I don't bother converting to actual A/F for the various fuels; as long as you know what numbers to look for, it don't matter. And the absolute number isn't all that important anyway, just a range.

Thanks,once I understood the pattern of the changes it started getting easier.

Going to check fuel mileage soon. Got 10.5mpg originally.

---

So what exactly did you tweek in the carb to dial in the cruise?

As delivered it had .070 AFR`s and .040? IFR`s
Tried lots of combos and basically realized that if the idle circuit is maxed-out at idle,it can`t get much richer at cruise. Tried small changes to both IFR`s and AFR`s till it almost isn`t enough fuel to idle cold.Also lowered the primary float to just below the hole. That go me the 13.5 cruise.
I expect mileage to be 13mpg or so. Got 10.5 @11.7/12.2 AFR,,,,,11.98 @ 12.5/7 AFR. Hope 13.5 yeilds a 13+.
