firehawk618 Posted June 14, 2014 Share Posted June 14, 2014 I'm almost 100% certain this A/F Learning is the result of a loose intercooler hose. Can anyone confirm this and let me know what the values should be? I'm new to this.

heiche Posted June 14, 2014 Share Posted June 14, 2014 yes. you might want to do a low pressure (about 5 psi) boost leak test to find it. values should be as close to 0% as possible, but under +- 5% is considered ok. here's a recent similar thread.

Gotcha, thank you much. I did have a large boost leak. I have just loaded back the stock bin on my ecu in anticipation of an opensource tune. I will drive easy and check those again.

bnguyenbb6 Posted June 15, 2014 Share Posted June 15, 2014 You have a leak at the manifold. Generally: Pre-turbo= lean everywhere Post turbo= rich everywhere Manifold=lean in vacuum, rich in boost/coming out of vac Link to comment Share on other sites More sharing options...
RallyMachine Posted June 15, 2014 Share Posted June 15, 2014 I got money on the turbo inlet Link to comment Share on other sites More sharing options...
firehawk618 Posted June 15, 2014 Author Share Posted June 15, 2014 It was an intercooler pipe. I forgot to tighten it down. Reconnected and the car ran fine. I just messed with the tune so I'll log some miles and pull lv again. If you guys want I'll post the new LV on this thread. Intake gaskets were changed a few months ago. Turbo inlet still stock but tested ok recently. 10' CTS-V, A6, Airraid, 2.4 upper, ID850's, self tuned. SOLD:06' LGT Wagon. BNR16G, Catless UP, DOWN, Hexmods VB, Hexmods diff bushings, BIG TMIC.
