Got a few questions hopefully i can get a few answers. first off first time posting( so be nice lol). has anyone messed with one of these yet? if not guess ill be the first. hope not lol. Second what would be the best way to set up the solenoid for emissons delete(simpilfied seq.). came with a mac solenoid and i have 4 more to hopefully replace the rest of the stockers. third has a AFR (lambda) control built in. Where is the best place to mount the bung for the senser. have a 3inch(i think came with the car) down pipe to stock cat and hks high power cat back and hks racing intake. frogot to mention i do have the apexi pfs with the commander. no tune yet but hopefully will soon. stock motor, stock injectors and an aem fuel pump. Any help will be greatly appreciated. thanks

 

We've installed a few of them. They're good and work well. The answers to your questions are in the instruction manual that came with it. Regardless of the turbo configuration, the twins have only 1 wastegate. The wastegate is whats being controlled by the Mac valve.

 

Is your car running good as is? What is the thought behind replacing all the solenoids?
If the car isn't having issues, I would leave it alone. The factory setup, as long as it's maintained should function just fine. If you haven't updated to silicone hoses, that's a good way to add some reliability.

The wideband sensor mounting location from the manufacturer:

• Weld the bung at least 24 inches downstream of the exhaust port outlet (after the collector), or 24 inches after the turbocharger if so equipped. The bung should be welded before the X or H pipe if so equipped.
• Using a clock as reference, mount the bung between the 9:00 o’clock and 3:00 o’clock position. Welding the bung in the lower section of the exhaust pipe can result in sensor damage caused by condensation making contact with the sensor’s internal heating element.

 

ok cool thank you. just wanted to make sure i was understanding the instrucions. i will definitely have some more questions when tuning time
. lol. as for the solenoids yes the stockers were going down hill. figured now is the time to up grade them.
