ECMlink critique my log/tune

[94allwheeldsm]

My idle seems to be ok, but the combinedFT is wack sometimes. Also at WOT pulls the WB reads around 12 <yikes. BoostEst. is way off. The EBC is set at 15psi and holds strong.

1000cc PTE's 3in Gm maf with link cable. My MAF Comp is funky to. Any time I ask Link to figure it out its always an eratic adjusment. Any way thanks in advance.

why is your log .csv? are you using v2?

the file was to big. I just uploaded a clipped section.

Why do you have fuel adjustment in both the sliders and the DA tables, especially the whack slider adjustments you have?

Your MAF Comp values need to be looked at again. There should be no massive jumps (e.g. -8.6% at 1800Hz to 29.7% at 2000Hz) and it should be as smooth as possible. You also should address the global scalar value and make sure that's really necessary.

Is there a reason your OpenLoopThresholds are around the suggested testing levels? Are you still using the built-in wizards to adjust MAF Comp?


Have you read through this link and gone through everything?

Yeah, I read through the tuning guide, I also watched the videos. I'm asking those questions you asked me....Im trying to figure out why the "wizard" is giving me whack ass values. no boost leaks, timing is set. I do have to set the Idle a little bit lower as it's not hitting the target of 950 I set, on link.

Should i reset those values and start from scratch? Thats what was suggested by the Mafcomp adjust tool. When i smooth all of the sliders out after the mafcomp adjust and go for a drive and I do the Mafcomp adjust it always gives more unrealistic values.

I just want to make sure I'm not missing anything stupid. It took me a while to dial in the airflow/rev with the sliders myself(no adjust tool). SO after all that i did the adjust tool and it was far out but didn't change my airflow/rev...

At idle the CombinedFT is all over the place +/-%10 how much I adjust the deadtimes but no go.

I personally didn't like using the wizard when I used to have my GM MAF. It did seem to produce some fairly crazy values, so I would just do my tuning by hand. It's not hard while using WBFactor as that basically tells you how much you need to adjust and in what direction. So to respond, I would personally start over.

As for the fuel values, the wizard didn't produce those values so I would zero out all of them. Just do your fuel tuning from the DA table.

Ok I figured the GM Maf was throwing it off. I will log WBfactor and adjust. As for the fuel values I set the WOT sections to 11 (that were 9 something?) in the DA table. Just go through and add some to the areas that are lean?

 

[snowborder714]

No. Your fuel DA table is the target that you want to see. You set this to your ideal values that you'd want to see. If you see a variance in your logged wideband compared to AFRaioEst (assuming your wideband is logging an accurate value), then your MAF Comp is off. This difference should show up in WBFactor. Once you correct this, the wideband should line up with AFRatioEst

Thanks for your time! I will do some resetting and doing it By Hand. I wasn't sure why it wasn't targeting 11.0 like I wanted it....Now I know why
