I tuned my afc 2.0 for great lfts at idle and cruise... now... take a look at my o2's at WOT... im running rich obviously... but around 970-990, im gettin NO kr.. but as i get NEAR 930, i get mad knock retard... what should my values be at for the 8, 9, and 10 frequency on the afc 2.0? As of now, the 8,9,and 10, are at 98.

I'd say it looks odd. If that boost is correct, you're only seeing a maf value of 10500 at 9-10 psi. I'm usually seeing 10500 at 14-15 psi. How old is your 02 sensor, and can you include MAP Kpa in your next scan?

Syp,

Do not base your numbers off your narrowband o2 sensor, if you are getting zero kr with 970-990mv readings, then keep it that way.

Also , watch your IPW's, you are hitting 20ms at 6000rpms, so your injectors are at 100% duty cycle. I am guessing this is why you peaked at around 3kr, your injector's are maxed at 6000 rpms. I would suggest on holding off raising shift points or going down to a smaller pulley, until you get larger injectors...

Good Luck.

That's a problem though. He should be nowhere near maxing out the injectors with the 3.4 pulley on there, even with the cam. The MAF signal looks screwy as do the IPWs.

 

[LPSPEED2]

yes, your scan is there, as indicated in the headline.

 

[CoolGTX]

I wouldnt be happy with those results..

 

[syP]

so no one has suggestions for the question i asked with the AFC?

 

[imported_Ron Vogel]

Not enough information in your scan for me to have an opinion.

I like to look at RPMs, Map Kpa, 02, IPW, Timing, KR, MAF Fq, LTFT

 

[syP]

i have MAP inHG if that is what you meant...

i will add that then scan again

 

[Jwood416]

To get that figure to kPa though you have to multiply by 3.386388. Thanks Chem AP and Physics AP! Wow I'm so glad that the only thing i can contribute to the boards has to do with class work as i still don't have a job to buy the mods i need.

syP what PCM are you using? Do you have an Intense or DHP and if so have you had someone tweak anything with it to adjust for any of your mods? I am wondering if you need a new flash in your PCM or something. Those numbers just don't match up, and something is really goofy there!

I am almost wondering if getting a new flash of whatever you run would be good to start fresh again?

It's supposed to be a DHP, but I was able to read it, and modify it...which I shouldn't be able to do. I fixed the Injector flow rate table, and 02's stayed about the same, but IPW's dropped to 16-17 at WOT. I tried to import my trans settings/Tq mgmnt too, but his trans didn't like it. I am starting to think something funny is going on with it. We went out after I flashed it with a stock MAF table, and new injector settings. LT's were off a little, but not too bad. 17 max IPW, .940 02's, 15 degrees timing...still seeing 4-5 kr. He had his mini afc set at 108 before we did the initial flash (which I would not reccomend a mini-afc above 105%) which we took out of the loop before testing, so we brought it back and I played with the MAF tables to start juicing up around 5000hz at 101.5%, to +6% at 11,500hz, 02's went to .960's. It had absolutely no effect I could see on KR.

Ultimately the car is not exactly a dog, but it's running no where near where it should be. Something is restricting airflow in there, because the MAF's not reading it flowing all that much.

yea im still gettin kr with teh 3.1" obviously.. me and ron didnt finish our tune session... we still need to do a few more runs, and check my grounds for power.

 

[imported_Ron Vogel]

Yeah, I'll clean up the garage a little and pull your car in. I want to go over and under your motor to check some stuff out. Car should be much quicker.
