Something seriously wrong?

I really dislike K&N’s for anything other then something used strictly for sand

I guess they're ok if the goal isn't to maximize engine life.

I have seen a number of desert bikes not survive a weekend with them. Silt and ash just passes through them.

Still better than the aftermarket "air cleaners" that we used back in the day -

I wasted too much time yesterday looking in vain for a pic of a tiny air cleaner over a v8.

Fab rats on YouTube just picked up a rat rod truck with one.

Well, just you rich kids had V-8s.

O2 sensor gaskets can probably be picked up at a local parts store.

So do I just change the scaling in rom raider or do i change the primary open loop fueling chart based off the afr average chart it gives me? And whats the afr cell hit count chart for?

You log for and change closed loop first.

Yeah i logged for open and closed loop and made the changes to scaling. So now i change POL or after logging some more driving?
And so for Stock afr do i put in afr or commanded afr?

No need to mess with those things when maf scaling. When you change the maf scale and reflash you need to put some miles on it again to let the ecu relearn fuel trims. You need to do that every time you reflash. Unless you see something bad in the logs like low IAM, crazy fuel trims, ect. Once I reflash I usually log the car once to make sure nothing bad is going on and then I don't bother logging again till I get some miles on it.

Sorry about derailing your thread, OP. No is on point. One step/change at a time and observe carefully.

I think i have tracked my idle issues down to the ac being on… idk. Only notice the problems and crazy afr when my ac is on. Thoughts?
