ECMlink ECMLink V3 Third Gear Pull Log,Needing tuning help

[racersedge1821]

Just needing a go over on my pull log and some advice.adjustments to be made. I'm very upset that my buddy's small 16g car on 22 psi. is spanking my hx40 awd so i am in desperate need of a tuner's help with my poor tunning

1. Does your logged value for the AEM match what the gauge shows? If so, you're running really, really lean at WOT.

2. Why are you adding fuel, especially via sliders? You should be taking fuel out and preferably via the direct access table. (Timing should be adjusted the same way.)

3. An HX40 at 10 psi (if your MAP sensor is reading correctly) is most likely going to get spanked by almost anything. That turbo isn't even close to being useful, let alone efficient. No wonder you're getting spanked

4. Your airflow sliders are really jagged. These should have smooth transitions and you also need to do airflow tuning in the upper RPM range.

5. Your battery voltage is pretty low during that pull. Something you might want to look into.

Your profile says that you're running speed density yet your log shows otherwise. Were you under the asumption that you were? In addition to what Brian has stated, I think it's best to take a step back, start over and get your idle/cruise dialed in and go from there...

Why are you adding fuel, especially via sliders? You should be taking fuel out and preferably via the direct access table.

Brian, if he's running lean, then he should be adding fuel. Did you mean the opposite? That said, his DA is rich (by default) and I totally agree that the target afr should be set in DA and only then airflow should be dialed in via maf sliders or SD table (if applicable).

Yes, if he's actually running lean, he should be adding fuel. But I see no way that he can be running 10psi on that turbo, flowing ~31 lbs/min, running 800cc injectors, that he could be that lean with that much fuel added.

I'd suggest to zero out the fuel and timing sliders and then start over. Then we can help you adjust the DA tables to do this properly.

Ah I see what you're saying.

Also, just noticed the tps is not 100%

Ty all for the quick responses,i have this same thread opened on ecmlink as well. I have (both) speed density sensors and a maf connected and i find it easier to get my car to idle with maf adjusters vs. speed density tables so thats why i am using maf to help me get familiar with how tuning works then i will transfer to sd

The guy's on ECMLink find that i may in fact have a faulty Fuel Pressure Regulator and they are assuming that my fuel isn't going up with my boost pressure. On a side note i have ordered a new AFPR. and hoping this will get things going again. Alli know about idle/cruise tuning is getting airflowperev to .25-.28 and combinedFT to +/-5 correct along with dialing in my 850's global -47 and dead time 330? do you too think that a bad FPR. can be causing all these problems?This may be an important note my vac. line is t-ed off to my boost gauge and my FPR. can this be causing my problem?
