is 7:1 AFR's insanely rich?
my innovate WB02 just recently started working again since it got warmer out (70 degress) and driving today i was paying attention to the AFR's.
cruising they're still between 13-15, but accelerating it would drop to about 9, and WOT would drop to 7.5 at the lowest.
is this bad? do i need a retune?
i don't think the setup matters, but bone-stock F22a1 with t3super60 @ 8psi.

either way, your desired AFR is between 11.5 and 12.0 in boost.... you are extremely rich, so rich that I would think you could wash the cylinder walls with fuel and damage your rings and what not.

not burning too much, if any oil at all. compression is still 180 across the board.
the car still runs absolutely perfectly, no hickups at all *knock on wood*. this setup has about 20K miles and 1.5 years on it, so if the motor happens to be on her way out i gotta spare one chillin in my garage awaiting a rebuild.

I think your sensor is off or something else is going on, I doubt your ignition system would even fire correctly at that AFR

No blue smoke at all? Burning oil doesnt have to be caused by the motor, your turbo can have a bad seal and cause oil to get into your downpipe confusing your wideband. I dont even know how it can be possible for a motor to run with 7:1 air fuel. I would think it would flood itself out at idle. Could be wrong tho.

the free air cal may be where to start. if the car is a manual, it should shut the injectors off during decel as long as the car is still in gear clutch out.
never was a fan of the innovative as a side note.

Re: is 7:1 AFR's insanely rich?
is that thing even accurate to that low of a air fuel ratio? Ur wideband only works when its 70 degrees +? My question also what type of fuel?

Re: is 7:1 AFR's insanely rich?
the sensor shouldn't be able to read anything below 10:0 to my understanding? and 7:0 at wot is wayy to rich, there's no way your car would be able to run at WOT for any amount of time at all.
even if no smoke comes out, atleast black smoke should be pooring out cuz that is insanely rich

Re: is 7:1 AFR's insanely rich?
gas
i'm fed up w/ the innovate now. this is like my 3rd one.
i'm pretty sure the entire LC-1 WB anddd XD-16 gauge are both ****ing up. the gauge was only working intermittently over the winter like it wasn't getting any power like a wire was loose. checked wires/connections today, and all were fine.
so if the gauge is ****ing up, my guess is the wideband is as well and giving false readings, altho the other readings are kinda accurate (i think haha. no way to verify)
yup, all wires good.

Re: is 7:1 AFR's insanely rich?
I had a innovative, i think lc1 just wired into my s300 (no innovative guage) and it never gave me any problems. Once it did something like this when the ground came loose. Im sure there is ways to test both the sensor and guage. I went with a aem this time around even though Iv heard of more problems with the uego than any other wideband.
