In my effort to relocate secondary air pump from right to left of center radiator, to gain more room for active cooling, I realized the essential difference between SL55 and E55 is with secondary air pipe routing.
The SL55 gets the hose under the passenger side inlet, while the driver side is plugged, and vice versa in E55
The question i couldn't answer in EPC, is does this rubber plug sell separately ? (this is a stock photo, dont mind the broken aluminum)
Disable the smog pump, and problem solved. Search for how to disable O2 sensors using Star hardware, and the info is in that thread. Good luck.
Smog equipment is not optional parts for hacking and removal, as they are installed to keep the car emission legal, and to place the ECU in closed loop feedback as quickly as possible after cold start, to monitor and adjust A/F ratios.
Disabling AIR pump, and disabling O2 will force the car to run off open loop preset table of A/F ratios, without any feedback to the ECM about the car running too rich or too lean, apart from knock sensors of course. In short, the car will run like crap, no matter what the internets tell you
At the absolute very least, the car will smell like an *** in the morning, without secondary air, and as a daily driver, I am not interested in that smell in my garage.
In addition, MA, along any other state with remotely enough population to significantly contribute to GDP, mandates these equipment, to keep the car on the road legally. Therefore removing this equipment is not an option for me.
I filled youtube with Xentry How to videos, so I can easily disable and reprogram any system you like in the car, I just choose to keep the car road worthy like the day it came out from factory
Could anyone please help with the part number if possible?
bayhas, is that meant to be some sort of pressure-relief device? I have ideas but I'd like to understand what it does before I throw out erroneous info.
Although the SC is upside down, its a better shot to explain, the two openings take the to exact same cavity in the SC housing, the only difference is how the hose is routed
