ECMlink MAFadjustment review

[Fehrion_sit]

this is my MAF adjustment after following the ECMLINK how-to. i used a long hill and normal driving to get this adjustment. a few of the markers seem out of order and im assure as to whether i should slope them or align them.

how-to i used v3mafadjcombft [ECMTuning - wiki]

Why are you not asking on the ecmlink forums?

Why are you not asking on the ecmlink forums?

well there are a total of about 6 people online on that forum at the moment. this section of tuning forum was the best spot.

But those 6 people are better equipped to answer your question, than the 10,000 "how do I vent my bov" people on tuners.

If memory serves me correctly, you could adjust the global settings for fuel to lower that line a bit. Mine had a huge jump in it from 50 to 150. I just tweaked globals and dead time to smooth them out and did it manually by watching my fuel trims in closed loop. Kinda fun changing numbers then adjusting maf sliders while driving!!
Now the tricky part is WOT tuning. Then, if you want to be true to your DA fuel tables, you will have to raise or lower a large section of that line further up the hz scale. You'll find out about that soon enough.

i have PTE680s which are set at 300millsec and a global of -30.1 ... my fuel trims were pretty spot on at the end of the log, i can up deadtime to 315millsec ?

after reading some more, i have found my answer

"This is my new, final configuration. To get that centered nicely, I'll click the "Change..." button next to "Global scalar" field and then click "Auto Adj" on the dialog that pops up. The application will center the current set of adjustments for me and produce an appropriate global scalar value. I'll then do an "ECU→Reset fuel trims" and go drive. Everything should line up much better now. "


using the auto adjust brings the adjustment down onto the center line.
