Just Got The Cobb AP: Please look at my data log

[topherdopher]

I currently only have a Mazdaspeed GenII CAI. Please let me know if the tune is looking safe. I noticed a little knock retard :-/ what exactly is going on?

BTW: I'm running the Stage1+MSCAI2 93 v107

 

[vikonic]

Not much knock, at least nothing to be worried about. I'd be more worried about the high LTFTs and your AFRs seem a little too lean IMO....Did you give the car some time to re-adjust after flashing?

You should be able to fix those a little bit with the ATR. Good luck

Yeah if your ltft's are still that high in a few days I would get ATR as soon as possible and calibrate your MAF.

I drove the car for about 100-150 miles before this data-log. Is it dangerous to be driving around while the LTFT's are reading high?

Tune is not safe. Check intake and boost tubes connections and make sure they're tighten up. Then reflash or reset ecu. Drive normal with no heavy acceleration for 100+ miles. You're holding boost just fine so bov is okay. Yeah something is not right here. If i'm not mistaken LTFT should be at 0 under WOT. AFR should be no higher than 12 specially with Stage1. .30s, .7, and .4 KR is pretty common so no worries there. Don't know what else to say.

You are running lean.
You LT fuel trims are way off.
You need to stay off the throttle till you get your ATR & calibrate your maf.

Well, you are a bit lean right at boost onset which COULD mean a post MAF leak especially if you just installed an intake. Make sure you dont have any leaks after the MAF sensor and before the turbo. That could cause a lean condition. Notice your knock counts are right around where the car goes lean. Typically we see much richer AFRs with these maps. Get some carb cleaner and just lightly spray around the intake and inlet tube. If idle fluctuates, you have a leak.

well I noticed that I might have the first gen mazdaspeed cai w/o the air straightener. So I ordered that. Think that might be whats causing the issues? I'm hoping that's it. I'll have it installed by next wednesday.

 

[topherdopher]

I install my air straightener, Cobb TIP, and Dog-bone (which I know won't affect the #'s) and did a 4th gear 40mph WOT log. Let me know if everything looks ok. Thanks guys!!

bump!! Any help?

 

[hugador]

Well it's getting better. AFR is still bit high. Give it more time to adjust. Might want to upgrade stock plugs to One Step Colder Plugs to help with KR. I'll just give it some time.

COBB Tuning Surgeline Head Calibrator Tim Bailey just looked at the log and said you are totally fine. It is a minor timing adjustment. If you want, you can run a lower octane map and it will run a tad less timing.
