Your AFC looks rich, so I doubt it is from running lean (I assume that is from a WB, not just the PCM guesstimate) ........

Run a few gallons of race gas to see if it dissapears, false KR can happen from many different sorces

 

[MuffHugger]

So you just went from 0-100? Go out and get a better scan.

 

[02BlueGT]

Oh, I forgot to ask, did you mess with the Torque management settings, cause IIRC it can show up as KR when TM kicks in.....

 

[Fish]

I get it too. Dont fret. Now I am getting spikes as high as 6, norm is 2-3, once and awhile 4* with my 3.5 on now.

your commanded afr changes to many times, you need to 0 our your pe adder table. Then it's going to take a night to get a sweet maf tune. Right now your problem is you're running way to rich and commanding quite a bit of timing. Where are you located? I'm pretty good at it, probably get you situated in 5-6 scans give or take. she just needs a little tlc that's all. From what i can tell you don't look like you've changed much from the stock settings of the ecu? Is that at least a canned tune? The more info you give us the betta.

We are facing the onslaught of winter-blend gas.

We are facing the onslaught of winter-blend gas.

fuck that shit

We are facing the onslaught of winter-blend gas.

I just went over to Gas City in my area to find some 100 octane, which they typically have, and according to the attendant Gas City has gotten rid of it's potent mix across the entire company. I don't know if it's true, though.

speakin of that i found out the hard way they switched over to e70... 11.8-12.0 afr's before, now 10.8... jerks. I've since re-tuned and it back on track. I saved the old tune for next year when they switch back since it was spot on. Fuel trims we all wacky too at -13 most of the time haha. The funny thing is i didn't change anything else, just the fueling. No kr what so ever. 0-125 run completely knock free 21-23* timing... seems like i wasn't taking full advantage of that 104 octane when i had it?

Ill check teh gas shitty in Schaumburg tomorrow.

 

[firemandan1700]

I live in tonica. So probably 2 hours max from most people on this board. Im sw of chitown about 2 hours.

I figured it was a bit rich, so i decied to go back to the basics.

The only thing that is changed from stock values is the last 3 numbers of the IFR are increased by 2

The af/pe is 11.7

And the GFS is increased by 1* across the board.


I put the tune on and drove a bit tonight and i will scan after work tomorrow. Let me know If what I did in changes is alright.

(I do have a wb, I just need to hook it up :doh

 

[firemandan1700]

So when it gets colder out, doesnt that tend to lean the car out?

 

[firemandan1700]

Oh, I forgot to ask, did you mess with the Torque management settings, cause IIRC it can show up as KR when TM kicks in.....

I have done the tq manegment based out of the wikituner website

Heres my scan with a 3.8. Scandepot is telling me that my other CSV file isnt a CSV file. So no 3.5 scan tonight.

DOH!! I noticed there is only one WOT segment in that one. And there is no KR there. Disregard.

Although, you do see KR coming in on the scan in random times. Kinda when my TCC locks up or I am going up a hill or under load. Never really know if that was tunable or not.

 

[Fish]

When it gets colder, it does lean out the car IIRC. The air is more dense so there is more O2 getting into the engine. Your car seems to be doing the same thing mine is. The PCM is pulling fuel at idle, and adding it under load and WOT.

 

[firemandan1700]

your commanded afr changes to many times, you need to 0 our your pe adder table.

So just set all the numbers to 0 heh?


Updated:
I had my scan gauge going, and I was seeing 2* +/- of KR

Maybe its because of the spark table... Do you think I should just have left the gfs table alone and run stock and see where that gets me?

The KR has come down and more of a consistant 2* +/-

Its getting there. Any help before sunday is appreciated.
