Title: Porsche ME7.8 Resonance Flap Post by: mikers4 on March 02, 2018, 03:13:00 AM Hello,
Hope someone can help me with an issue I am having. Porsche 996GT3 2004 car running Bosch ME7.8 and they run 1 x resonance flap as standard. I have converted my intake manifold to a later model 2007 997GT3 and they run 2 x resonance flaps as standard. My ECU has both resonance flap maps and when emulated with OLS300 the map is active. I have checked a later car wiring diagram and it uses pins C4 and C16 for the flaps. Mine uses pin C4 and then pin C16 is not used. I have checked pin C16 and there is a frequency flashing on the power probe led. No matter what I alter on the flap2 map nothing happens. I have found the following: SUMODE - No energization of the suction pipework SUMODE01 - Energization of flap1, No energization of flap2 SUMODE02 - No energization of flap1, Energization of flap2 SUMODE03 - Energization of flap1 and flap2 No matter what configuration I have tried I can not even turn off flap1 so what am I missing ? Any help appreciated. Mike Title: Re: Porsche ME7.8 Resonance Flap Post by: nubcake on March 09, 2018, 11:48:10 AM Been there, although a while ago.
You're talking about KLSU2 when you mention "the flap2 map"? I'm a bit shady on the details, but also check CWSUKOR and CSU. On top of that - make sure your (KF)KISRM and VE maps are correct to properly take advantage of the different intake. |
