Okkkk so the boyfriend (I'm posting on his name) bought a 06 Evo 9 SE. We installed the Injen IC piping kit with air intake last weekend. We drove it around fine, then he got on it a lil bit in first, and went through it fine. Then second and third felt like he hit a brick wall. And in fourth it doesn't want to go to 4k. We checked all the piping and it's still on, but it's making a sound that is kinda like it's in open waste-gate or bov.

 

The brick wall experience is when the car hits fuel cut. Car needs to be tune.

 

you probably hit boost cut which can be adjusted by flashing the ECU, let me know if you need my services (sig)

 

Never heard of anyone getting fuel cut from just adding I/C pipes and an intake. Triple check all your connections for leaks, especially the one going to the intercooler and your BOV connection. Make sure the vacuum line didn't come off either. While you at it, make sure you didn't put the BOV on backwards.

 

yea i didnt think it would cause problems like this when i put it on i can go in to boost it just bascailly blows off ... everyline is tight and on right car worked fine in and out of boost when i took the gf and her parents to dinner after doing it ... then i wanted to see what full boost would be like on the way home ...when through first and in 2nd hit a wall figured it was boost cut or something but i guess ill just flash the ecu now

 

Flashing the ECU should help. I had the same issue when I put on a pipe. Basically, it was explained to me that anything you do that causes a change in the A/F such as a test pipe/HFC, intake, injectors (duh), etc. you should get it reflashed. The change in the intake to a hard pipe from the stock accordian tube "can" cause a type of turbulance in the way the air enters and reads at the MAF. Hope you get it taken care of

 

This might be a dumb idea, but may be worth a try. How about resetting the ECU? I know when I installed my intake I would throw a check engine light, I reset the ECU allowing it to relearn what going on. Might be worth a try.

 

did it twice now even tried to see if it had a code with an scanner at work today didnt have any codes unless there is some weird way to reset the ecu?? i know idle relearn is 10 mins and i did that

 

did you pull the battery terminal off for a few minutes? Also, did you check for the codes after reseting the ECU? if you did that would of erased all of the codes.

 

yes i took the battery cable off ... but i tried to pull the code first before i did that ..no code

 

Its fuel cut for sure, get a tune.

 

in the works already thanks for everyones input

 

Leaking somewhere in the IC piping?
