Wacky AFR's at cruise
#27
My car does this at cruising speeds while on the hwy. Periodically I just cancel the cruise control and reset it. I feel like you're chasing your tail with this one houston. BUT if you do find something be sure to share lol

Previously I didn't have my cobb in the car and it never dawned on my to log it (I always assumed it was my tune). now that I know its not my scaling
Tomorrow I will just drive until it does it...lol it usually take 30+ min of driving to go into the 11-12 range. but I haven't been driving that much recently
I am running brand new stock red's and yellow's

well in an effort to get rich logs I have a lean issue for the first time...ugh
cruising at 70ish trying to get data and it randomly went lean. I don't see anything obvious on the log but check it out.
I did get a mild rich log but from what you guys say low 13's are normal closed loop
After it cools down I plan to pull the UIM and check around.

killing me....lol
so what you are saying is that the car should stay in the 16's even though the target is 14 assuming no hill or accel pedal change?
I just know that what is going on is not right but I can't get the data...
here is another log of going lean with no change to accel pedal and no change to Calc load

it is safe to say I would see a vacuum leak in the STFT #'s right?
I am at a loss unless the ECU is possessed or there is a "resistance" in a wire somewhere (I have been through 2 MAF's and 2 o2 sensors with the same results (so to speak)...hhhmmmm

I am convinced the richness is normal. Think about the gear you're in during the rich stint. If under WOT that sounds like a perfectly acceptable A/F ratio. I wish OL/CL was more controllable.

I've poked around in my car trying to figure out what causes this issue, but the thing I don't get is why you these cars will go OL at 3500rpm and cruising, but stay CL until 5500rpm at WOT. Seems like you would want it to go OL earlier at WOT than cruise.
I wasn't aware that the Baro sensor had an effect on latency, I might try swapping mine with a friends and see if that changes anything, mine actually broke(but was glued back together and seals still) so that might be an issue.

I'll take 13s over 16s any day. Even in a nice vacuum situation (40-50 MAP) you should still maintain your target AFR if your TPS is above 0%.
Overrun is a different situation entirely... your fuel will actually cut and your AFRs will swing up to 20... that is completely normal.
