notthesnail Posted August 31, 2010 Share Posted August 31, 2010 So, at a dyno day I found out that I'm running really rich and I'm not hitting my target boost levels. Can some of you experienced people have a look at the logs and suggest where I should be looking to make corrections, either physically or to the tune? Car is 06 LGT 5EAT with STi UP, Invidia catted DP, AVO panel filter, ~95k miles. Oil is 5w40 synthetic, fuel is 91 octane pure gas. I've attached logs for three pulls and some time in between, plus the dyno chart. I'm also looking for opinions on the chart itself, but I don't want to bias you, so I won't say what opinion I have already (I will later). Thanks for looking.romraiderlog_20100827_DynoPull1.csvromraiderlog_20100827_PrePull2.csvromraiderlog_20100827_StartPull2.csvromraiderlog_20100827_DynoPull2.csvromraiderlog_20100827_DynoPull3.csvDyno run - 27Aug2010a.pdf Link to comment Share on other sites More sharing options...
Ridgeracer Posted August 31, 2010 Share Posted August 31, 2010 You have a decent amount of knock around the 5K+ area of your map. You might be running too much timing for your fuel. Can you post a LV so we can see your fuel trims? "Gimme mines Balboa...Gimme mines".....Clubber Lang - Mr. T Link to comment Share on other sites More sharing options...
NSFW Posted September 1, 2010 Share Posted September 1, 2010 A boost leak will make you run rich and lose boost. Look for one. Link to comment Share on other sites More sharing options...
notthesnail Posted September 1, 2010 Author Share Posted September 1, 2010 I pulled this LV this morning after my short drive to work. I might be able to do a harder drive at lunch and post again. I'll look up how to check for boost leaks.LearningView_01-09-2010 9AM.csv Link to comment Share on other sites More sharing options...
notthesnail Posted September 7, 2010 Author Share Posted September 7, 2010 I found a loose clamp on the intercooler to intake manifold hose. It must have been crooked from the last time I had the intercooler off and worked its way loose. I checked everything else in the path, which seemed fine, and cleaned out the air filter (AVO panel). Now to log and see if that was it. Link to comment Share on other sites More sharing options...
