I just got done installing AEM tru boost controller on my IX,and Everything works fine except for i'm completely overboosting hitting 25+ psi, My duty cycle is set at 10%,and my crack pressure at 1. Is there something i'm doing wrong? I thought the lower the duty cycle the lower the boost pressure.

Any suggestions are greatly appreciated.

 

I recommend changing the crack pressure to 11.5 - this has a big affect on spiking.

Give it a pull, but keep your eyes on your psi and a/f ratios... o and the road also.

Good luck.

 

What is your A and B settings? What is it set on? You could be set at a higher duty cycle on the b setting and not know it.

 

Thanks guys, I beieve Both A and B are the same, but I will double check. I just dont see how running the lowest duty cycle would pass 25 psi no problem. I thought running a larger crack pressure would spike more?

 

hallman pro ftw

 

Double check your vacuum line routing.If you like to pull over and pop the hood everytime you want to increase psi then sure. You are also able to log with the aem unit. The aem unit is nice and super simple.

 

Yeah i upgraded from the hallman es mbc, thats why i'd rather not go back haha.
