caramall2 Posted May 10, 2009 Share Posted May 10, 2009 Just making sure I have it correct. In the TD coarse and fine tables, a "positive" number means actual boost is low, thus the correction is a positive % increase in WGDC, correct? For example, on the TD fine table (street tuner) if I lower the right hand value (150mm HG (2.9 psi)) from 9% down to 7%, that means that if boost is fairly low (target-actual > 2.9 psi), it won't try and correct quite as much (7% vs 9%), correct?

Spec B Posted May 12, 2009 Share Posted May 12, 2009 In RR, negative TD means you are overboosting and WGDC is being pulled. That is the extent of my understanding of it. Link to comment Share on other sites More sharing options...
mickeyd2005 Posted May 12, 2009 Share Posted May 12, 2009 Using Cobb's label makes it confusing. It is not "fine" or "coarse". One is a proportional and one is an integral. Link to comment Share on other sites More sharing options...
mickeyd2005 Posted May 12, 2009 Share Posted May 12, 2009 In RR, negative TD means you are overboosting and WGDC is being pulled. That is the extent of my understanding of it. Just for clarification. Negative TD proportional means you are overboosting. Or if TD cumulative integral is dropping you are overboosting. Link to comment Share on other sites More sharing options...
