AP Datalog shows more than 100% Injector Duty Cycle; should I be concerned?
I've been seeing spots in my datalog where the Injector Duty Cycle goes over 100% and wonder if I should be concerned.
I'm using the Stage1+AEM 91 GSR v108 map and it states peak boost is ~23.5 but occasionally my boost will go over 27 psi on my stock BV (bypass valve). I've heard our stock BV can handle up to 30 psi so I'm assuming that I'll be alright but just want to be sure.
I have the AEM Box Cold Air Intake System, 21-678C and on the turbo inlet hose there are 2 vacuum hose connectors. On the stock turbocharger wastegate solenoid, there are 4 vacuum hoses and both the left pair and right pair go to a T-connector and become 2 vacuum hoses. Stock turbo inlet hose only has one vacuum hose connector so I was thinking why not open up the flow and get rid of the T-connector since the AEM turbo inlet hose has 2 connectors anyway. Later I've found out that the pair of vacuum hoses closer to the front of the car that comes from the turbocharger wastegate solenoid have brass pills in them (still there). Does anyone know if there should be pills in the other pair of vacuum hoses that go to the turbo inlet hose? I went to check the stock hoses with the T-connector that I've removed and didn't find any pills there (if there was, they might have fallen out). If so, how does this affect performance. The pair of pills is still installed on the other pair of vacuum hoses.
