Spec B Posted February 17, 2009 Share Posted February 17, 2009 The fact that IAM in not at 1, is not a good sign. You need to get your IAM to 1 and then log again. Link to comment Share on other sites More sharing options...

WRXnate Posted February 17, 2009 Share Posted February 17, 2009 could you PM me where you go your vf52? and maybe a price you got it for? Link to comment Share on other sites More sharing options...
Spec B Posted February 17, 2009 Share Posted February 17, 2009 The car is moving some good air considering (since the IAM is at .5). Also, you are logging too much stuff..next time only log: Engine Speed Manifold relative pressure Primary Wastegate duty cycle MAf g/sec Knock Sum (if you are using romraider) Engine Load (g/rev) Ignition total timing Throttle opening % Start your log 2000 RPM to redline. Also post your learning view. Link to comment Share on other sites More sharing options...

mickeyd2005 Posted February 17, 2009 Share Posted February 17, 2009 You're overboosting in your 1-3 log, but you're underboosting in your 3rd gear log. You're staying in closed loop too long. 3682 rpm and 13 psi boost is too much for closed loop fueling. Link to comment Share on other sites More sharing options...

mickeyd2005 Posted February 17, 2009 Share Posted February 17, 2009 Is this an e-tune or a local tune? Are you using the stock BCS? If you are, I recommend that you remove BOTH restrictor pills. And use a single 1.0 mm restrictor pill between the compressor nipple and the T. Then retune boost control from scratch. I think the secondary restrictor pill is causing the overboost during fast spoolups. There's not enough time for the actuator to fill up to open the wastegate. In the slower spool ups (3rd gear from 2000 rpm), the time it takes to spool up is long enough for the wastegate to fill. I know the EVOs use two pills, but I'm not a fan of it. I don't think putting a restriction between the T and the actuator is a good idea. Just my $0.02. Link to comment Share on other sites More sharing options...
kb2spn Posted February 17, 2009 Author Share Posted February 17, 2009 Stock BCS,E-tune,I did not realize that there was 2 pills in the VF-52,I just place d the original pill in(not sure of size. New LogsLgt-3rd.csvLgt 1-3.csv Link to comment Share on other sites More sharing options...

mickeyd2005 Posted February 18, 2009 Share Posted February 18, 2009 Taking out the second pill almost didn't affect your 3rd gear boost but your 1-3 overboost dropped. It's still overboosting. You're still getting some big knocks because of it too. Link to comment Share on other sites More sharing options...
testes1010 Posted February 18, 2009 Share Posted February 18, 2009 I'm going to go out a limb and say your AFRs are pretty lean(regardless of what the stock o2 says). I'm running at ~11.3:1 AFR(via wbo2) with similar peak air flow numbers with IDC% up in 98-99% range. Link to comment Share on other sites More sharing options...
