prolly dynamic advance. on STi's i think it runs from .1 to 1 or something like that. this is the dynamic part of the ECM's iginition timing, and will lower itself when it thinks knock is present. low = knock, high = no knock.

the range on the v2 AP is from 0 to about 6.5 is as high as i've seen it go so far. this have any relativity to the advanced multiplier?

for that matter, can someone list all the live data gauges? I have them but don't know what they all are, i posted about this but can't find my post. It's not in the manual or on their website.

oh i change my answer... if the range is like you said mark, it's prolly not the DAM (like i thought), it is indeed the actual amount of timing added to the base map. which the DAM is used to calculate.
there is dynamic advance (the amount of timing addded). and dynamic advance multiplier (the number that varies to dictate the actual amout of timing to be added) |

then what is the difference between "ignadv" & "dynadv"?

ignadv is probably the actual timing being applied. IOW's, ignadv should be the total timing, while dynadv is the amount added to the base map to arrive at ignadv.
although i admit i am guessing a little here. i konw how the ECM's iginition system works but i don't know the list of parameters the APv2 has... |

wgduty i'm guessing is the percentage the wastegate opens to prevent overboost? the highest i can make it go is when it's in 5th and i step on the pedal at about 3k rpms, it goes to 78. the MAF is a weird number too... it hangs out arouns 2-4 at idle but at wide open throttle in say 3rd gear i had it over 200. i know it's not voltage now IGN doesnt do much either... i'll have to list all the other live readings and post them, and if you want me to test something and post it lemme know.

Thanks for the educated guesses. I will call Cobb and post up what they say.

Check out the AccessECU Tuning Guide Thread (www.cobbforums.com).
There is a PDF linked in there, and it explains Dynamic Advance, Dynamic Advance Multiplier, and Ignition Advance toward the end of the document. You may be able to find a few more definitions in the StreetTUNER Manuals available on their site. Quote:

my Dyn got up to 7.5 last night... I guess this is a good sign.

bump for answers, Ign, Dyn, WG, MAF, I have an idea but some of the numbers aren't correct.

like MAF... at wide open throttle it's 204, i know it's not 204 volts. and not 204 cfm. I just want a guide from COBB to tell us what the heck we are looking at!

Airflow in grams/second.
See page 56: http://www.accessecu.com/support/st-dbw-userguide.pdf You may want to look at a streetTUNER guide for your model of vehicle for more precise descriptions. Some things vary slightly from model to model Example: DBW DAM is .05 - 1.00 in .05 increments, while cable throttle DAM is 1 - 16 in increments of 1. |

right... i'm DBW and i'im reading 7.5 Not correct, this stuff makes no sense, no answer on cobbforums either. So pretty much everyone with a v2 Ap is clueless.

edit-> It doesn't mean much w/o DAM, RPM, load, and ignition table settings. More ignition tables than you'd think. It doesn't make sense to you, but the data may not be useless to your tuner. You may be missing too much information to make sense of it. It may not seem intuitive, but I've found the system to be flexible and (most importantly) safe.

I agree, i wish cobb woud of explained these live data modes in the freakin manual. Dyn Adv shows 7.5 at WOT.

Dynamic Advance (that you log) comes from a formula. Without more information "dyn adv of 7.5 at WOT" doesn't mean anything. I don't know any other way to say that. |

yesssssssss i read it. still, the most info i've gotten is from a street tuner PDF to a forrester. Cobb needs to put out a supplement that says Ign = this, dyn adv = this, WG duty measures this... It's like getting features on a cell phone and they don't define them in the manual.

The dynamic advance numbers don't mean much if you don't know what the max dynamic advance is in the map.

BUMP, seriously I don't know what am I looking at? Which of the live data gauges should I pay attention to? I'm just clueless. At least I know how to read and understand the MPH gauge .

without knowing what the dynamic advance values are for a specific RPM and load site, the dynamic advance number that spits out of your AP is useless. and the MAF reading, is Grams/Sec of airflow. 1 Gram/Sec = ~ 1 WHP, If everything else is optimized (fuel, spark etc.)
