nrmustang Posted September 23, 2011 Share Posted September 23, 2011 Hi All, Brand Noob here with an AP question. I have an 05' 5EAT LGT bone stock (except K&N Panel Filter), I bought a used V2 AP, updated it and threw in the ACN91 Stage 1 map (California gas). At the top end I get bad knocking/Det, right around redline. I datalogged it and the DAM shows "0" all the way until a bit of load is put on it. Then it goes as high as 6.5 - starts dropping - then about redline hits between -.50 to -2.0 (which is very audible). What gives? From everything I read, the DAM should stay consistently at 1 right? Why the "0"? Does the car need to "settle" into the tune. Has anyone else had this problem out of the box? Im new to modding my LGT, but not modding in general. My SCT's for my 03' Cobras & Mach-1 didn't do this. And my Predator for my SS Camaro didn't do this. Is the LGT just more sensitive, or is there something I'm missing? But to be fair to Cobb, biggest handheld tuner power I've seen aside from my Cobra SCT by far! If I can figure this out it'll be an ANIMAL! Thanks in advance Link to comment Share on other sites More sharing options...
iNVAR Posted September 23, 2011 Share Posted September 23, 2011 DAM (Dynamic Advance Multiplier) should be at 1, yes. I don't know how you would get a -6.5 though, that doesn't make sense or -2. That's not how DAM works. I haven't had an AP in a log while, but I suspect you are mixing up DAM with a different logging parameter. What Cobb calls DAM is the same as ROMRaider calling it IAM (Ignition Advance Multiplier) Your car shouldn't have to settle in with a tune, at least not like this. There will be some learning involved, but you shouldn't be getting severe knock, certainly not something you can actually hear. Log the following parameters and post the logs: DAM Engine Load Throttle plate/position Knock sum Feedback Knock Control Fine Learning Knock Control Total Timing Boost Mass Airflow Mass Airflow voltage Wastegate duty Engine speed That should be pleny. Also, post up a the learning table if you can connect a laptop to it and run AccessTuner Race. http://legacygt.com/forums/showpost.php?p=3031807&postcount=9 Link to comment Share on other sites More sharing options...

It looks like you are logging dynamic advance which is different than DAM which will fluctuate based on throttle and how the map is set up. Some see negative da in cruise on the cobb maps. Log what invar suggested and check back in.

nrmustang Posted September 23, 2011 Author Share Posted September 23, 2011 Thanks for the input. my DAM goes +6.5 down to -2.0. If I can figure out how to attach my Data Log, could you let me know what I'm looking at? Its a long file, but around 3-4k it sits at +6.5 (such as at lines 164-172 & 811-844) At line 664-666 it hits -1 to -2 briefly, but then at line 873-882 it sits at -1.5 to -.50 for quite a while (between 4700-5200rpm) I'm afraid to take it back out for another round of DLdatalog5.csv Link to comment Share on other sites More sharing options...

bmx045 Posted September 23, 2011 Share Posted September 23, 2011 log fine learning knock and feedback knock, engine load, engine speed, manifold relative pressure(boost), wastegate, mass airflow g/s, ign total timing, throttle plate angle....we can work around that odd DAM reading Link to comment Share on other sites More sharing options...
iNVAR Posted September 23, 2011 Share Posted September 23, 2011 Positive numbers in DA are good in general (it means your timing is being advanced) but doesn't necessarily mean you're not getting knock. The negative numbers are what you need to worry about. I suggest you read some of the posts in this forum to understand what you are seeing. I'm afraid your log doesn't really tell us a whole lot because you're missing way too many parameters. Take out fuel economy and Vehicle speed. We don't need that.

nrmustang Posted September 23, 2011 Author Share Posted September 23, 2011 Thanks guys for the help. When I get ready to go out for a DL, do I just scroll through the list of items in the AP and select the ones I want one by one? This was my first log ever, and I just found the DA and selected it, the rest was already there I guess. Also, no laptop. If we find a problem, whats my options? E-tune to clean it up? If so how would that work with the AP? Access Racer? Ive read a lot, but just trying to be specific. Thanks Link to comment Share on other sites More sharing options...
iNVAR Posted September 23, 2011 Share Posted September 23, 2011 I would REALLY try to get that learning table pulled somehow too. edit: No laptop? Hmm... Might not be able to get the learning table from what I can see then. Okay, just log those parameters and it should help a lot. Link to comment Share on other sites More sharing options...
bmx045 Posted September 23, 2011 Share Posted September 23, 2011 and keep the log files short, like a 3rd gear pull from 2k to redline only. Link to comment Share on other sites More sharing options...
nrmustang Posted September 23, 2011 Author Share Posted September 23, 2011 Thanks for the help. Have you guys heard of this before with the AP? Again, whats the fix? Link to comment Share on other sites More sharing options...
iNVAR Posted September 23, 2011 Share Posted September 23, 2011 You need to do the logs first before we can really say anything. So far, the only thing you've showed/told us that could be from knock is the noise, and that might not be knocking. edit: Actually, from the little info available from your log, you probably DO have some knock in the upper RPM range, but we won't know the extent of things until you log those items with the parameters. Kind of groping around blindly right now. Link to comment Share on other sites More sharing options...
nrmustang Posted September 23, 2011 Author Share Posted September 23, 2011 Sounds good, I'll try to get to it this afternoon. Where can I download Accesstuner race for the LGT? Nevermind, I think I found the link on Cobb's website Link to comment Share on other sites More sharing options...
bmx045 Posted September 23, 2011 Share Posted September 23, 2011 BTW, you're measuring a different DAM, you want the DAM multiplier..apparently there are two diff log parameters Link to comment Share on other sites More sharing options...
iNVAR Posted September 23, 2011 Share Posted September 23, 2011 http://www.cobbtuning.com/info/?ID=4214 But to pull the learning table the car has to be connected to a laptop. Link to comment Share on other sites More sharing options...

nrmustang Posted September 24, 2011 Author Share Posted September 24, 2011 Pulled a new Data Log tonight based on earlier discussion... What do you think? Sorry for the PDF format, it was the only one that would let me upload. datalog8.pdf Link to comment Share on other sites More sharing options...
iNVAR Posted September 24, 2011 Share Posted September 24, 2011 Ergh, reading that log is really hard... You should be able to attach CSV files just fine. Isn't that what the AP dumps the files as? edit: From a quick look over, you're definitely experiencing knock but like I said, hard to read the log.

nrmustang Posted September 24, 2011 Author Share Posted September 24, 2011 Yes it does dump them as csv files, but fr whatever reason the uploader keeps saying "invalid file". Link to comment Share on other sites More sharing options...
