nka Posted May 15, 2009 Share Posted May 15, 2009 I just connected "Learning View" to my ECU and it's show the IAM at 0.5 ? Seem's the engine is not happy... I need a datalog too, 2nd gear ~2000-cut off. Sound bad ?? edit: wasn't able to upload .xls, so I renamed into .csv ! edit2: Legacy GT 2005, 5MT, bone stock.romraiderlog_20090515_161944.csv Link to comment Share on other sites More sharing options...
nka Posted May 15, 2009 Author Share Posted May 15, 2009 Ah and btw, Learning View is giving me 0.00 everywhere, except for the A/F Learning #1 % Stored, the 0 - < 5.60 = 3.50" Link to comment Share on other sites More sharing options...
nka Posted May 15, 2009 Author Share Posted May 15, 2009 I found that : http://www.legacygt.com/forums/showthread.php?t=111841 I'll try to reset the ECU and try again. Link to comment Share on other sites More sharing options...
Infamous1 Posted May 15, 2009 Share Posted May 15, 2009 You are alright. More than likely your ECU has not learned enough to advance you IAM to 1.0000. It seems you have reset your ecu recently, the initial IAM on the stock rom is .500. Link to comment Share on other sites More sharing options...
nka Posted May 15, 2009 Author Share Posted May 15, 2009 still 0.500, even after 20 mins. I runned on idle and pushed the thottle slowly, I notice that "pulsing" thing ( http://www.legacygt.com/forums/showthread.php?t=112051 ) I got when running is also there on idle. I see a FeedBack Knock of -2 and a Knock Sum or 8... only on idle... And yes, ECU was changed like one week ago (~1000KM) for the fan relay. How long should I wait ? Is there's something wrong or my ECU is just learning ? Link to comment Share on other sites More sharing options...
NSFW Posted May 16, 2009 Share Posted May 16, 2009 Lots of 0s in your AF learning is another sign of a recent reset. Knock sum on idle will increment sorta randomly, don't worry about it. It also increment during cruise (< 2500 rpm) even on the stock tune. My car won't advance IAM until I give it some throttle. I can drive around my neighborhood and still be at 0.5, but it quickly rises to 1.0 as soon as I find an onramp. What modifications have you made to the car?

I can drive around my neighborhood and still be at 0.5, but it quickly rises to 1.0 as soon as I find an onramp. The things is : When I first look at it, I did run about 1000KM (in the city 30-70KM, highway up to 180 KM/H and also cruise control at 120KM/H for like 2 hours!) and it still was 0.5 ? well, at least it's seem to be "normal" Link to comment Share on other sites More sharing options...
NSFW Posted May 16, 2009 Share Posted May 16, 2009 That is a bit weird, my car always rises to 1.0 before it hits 100 kmh / 60 mph. Can you post a learning view snapshot? I'm still curious what mods (if any) have been done to the car... Link to comment Share on other sites More sharing options...
nka Posted May 16, 2009 Author Share Posted May 16, 2009 no mods, totally stock ! (Well... suppose too, I just got the car, 2 week ago). This is the learning view after the ~20 mins run, but it was exactly the same after the 1000KM I did. (all 0.00 except for the 3.90) The ECU is new, have been change for the fan relay recall !

NSFW Posted May 16, 2009 Share Posted May 16, 2009 ...but it was exactly the same after the 1000KM I did. Is there any chance that you've mixed up the screen shots, or it didn't connect and update after the 1000km drive, or it got reset after the drive and before you took that LV? Because that looks like a Learning View from a car that's barely been run since the last reflash. Link to comment Share on other sites More sharing options...
nka Posted May 16, 2009 Author Share Posted May 16, 2009 I didn't take the screenshot at the 1st time, so this one have a about 20 mins running, 30 KM and notting above 60 since the last "Reset ECU". Maybe I should just go do some highway and look at it again. Link to comment Share on other sites More sharing options...
Ridgeracer Posted May 17, 2009 Share Posted May 17, 2009 FLKC clears every time IAM changes. Car should advance the IAM after some spirited driving right away providing it doesn't hear alot of knock. As for knock sum at idle, on a stock car this should not happen (or at least it doesn't on my car). Have you recently changed gas stations??

nka Posted May 17, 2009 Author Share Posted May 17, 2009 I filed only twice since I got the car, one time at Petro Canada with 91 and the 2nd time at Ultramart near where I live, 91 too... I need to fill up soon btw... Link to comment Share on other sites More sharing options...
Guest Posted May 17, 2009 Share Posted May 17, 2009 Reset ECU and accelerate steadily under light boost (~3-5 psi). I get IAM bumped from 0.5 to 1.0 within 0.5 mile or less. I noticed if you don't get IAM bumped up quickly then it may take a longer while. Link to comment Share on other sites More sharing options...
Deaks2 Posted May 17, 2009 Share Posted May 17, 2009 Even on the stock map I had knock with Canadian 91 octane, I used Petro Can 94 (Qc) or Sunoco 94 (On) to get around that issue... Link to comment Share on other sites More sharing options...
nka Posted May 17, 2009 Author Share Posted May 17, 2009 IAM is back to 1.000 I reseted and he got back to 1.000 within 10 mins ! btw, I don't have 94 here in Quebec City, only 91... Link to comment Share on other sites More sharing options...
Spec B Posted May 17, 2009 Share Posted May 17, 2009 Reset ECU and accelerate steadily under light boost (~3-5 psi). I get IAM bumped from 0.5 to 1.0 within 0.5 mile or less. I noticed if you don't get IAM bumped up quickly then it may take a longer while. I noticed that if you go 60-70% throttle (more than (10 psi) IAM climbs quickly after a reflash or a reset...assuming you do not have knock. With very light boost, it takes forever for IAM to get to 1 on my car. Link to comment Share on other sites More sharing options...

rtbrjason Posted May 18, 2009 Share Posted May 18, 2009 I get some knock sum increments during idle and cruise, and I know I'm not alone. I sometimes notice a knock sum of 1 or 2 before having backed out of my driveway.. As for cruise knock sum, I see a ton of it. Almost always in 4th gear, 2800~ rpms and 0.40-1.00 or so g. That's about cruising speed at 45 so I'm commonly in those ranges. I can see as much as 30 knock sum counts in a short drive or as little as 10 or so.. It seems fairly random, but lately I've been noticing that it seems to be less in S mode vs S#.. I've messed with timing in this range with no luck.

Spec B Posted May 18, 2009 Share Posted May 18, 2009 I would not pull timing off the stock portions of the map (low load/low RPM)..if you pull too much timing I have read (no personal experience) that your EGT's may skyrocket in the cruise range. I too struggle with what I believe to be false knock at idle and cruise. 98% of it is below 2500 rpm and 1.00 g of load (entirely in the stock portion of my map). It was so bad that the low end knock was causing my IAM to drop. I ended up raising the flkc threshold to be active only after 2500 RPM. IAM has been rock steady since and my LV's are very clean with just -.35 being pulled in the low load 2600-3200 rpm range. Link to comment Share on other sites More sharing options...
nka Posted May 18, 2009 Author Share Posted May 18, 2009 hum, so too many false positive cause the car to correct this and then, affect the higher RPM... smart ! Link to comment Share on other sites More sharing options...
