Need some help. I had my greddy boost controller spec II installed in the car had it set between 22 and 23 psi and also have a BOV set to 50%-50% and a few hour after having my boost controller installed my Service Engine Soon light came on any idea.

 

Did you leave the stock solenoid hooked up? Not sure on the X, but I know on VIII & IX if you disconnect that, it can throw a code.

 

Did u hit a fuel cut? Even a minor one could throw a code.. Check the code..

 

OK well i took it to my mechanic and it got a fuel code. IT was because i was running to rich because i had my BOV set to 100% atmosphere and with the extra boost from the boost controller not tampering down as much it set if off so i am gunna try the 50% to 50% and see what happens. But this is a heads up for any one thinking about doing this.

 

I took my mbc off, i didnt want to deal with the ses light and or limp mode. ill put it back on when i cant get it tuned for it.

 

I hit a fuel cut tonight with my Hallman MBC and it throw a service engine code .... it didnt do it during the day when i "got on it", but i got on it tonight and it threw it ( it was 62 degrees out )

 

Ya i was throwing all kinda of SES lights. SO i just on pluged my EBC untill i get all my performanc parts and can get it tuned then ill plug it back again. The light wont hurt just unplug the battery or just drive the car and it will go of on its own. But if you keep driving with the boost controller then it will still pop the SES light so you might want to think of un pluging it.
