Hey guys, i bought the RMR filter bracket kit yesterday, and i put it on today. I disconnected the battery and everything even though you really don't need to. However, now the car is up and running, and it's slower, it lags, and there is a major difference in performance, but not gains, actually loss. It doesn't pull hard at all. Very disapointing, i don't know why. Everything checks out, and nothing is leaking, or loose. anyone have any suggestions or ideas? I like the RMR kit as a whole, it's very well done, and fits well.
But i just can't figure out why it lags and is slower now. is there some re-learning that the ECU does after it's been disconnected?
i just don't know.

 

When you disconnected the boost valve that is attached to the air box and bolted to the RMR bracket, you might have switched the vacuum lines around. That will cause you to run very low boost making the car feel very slow. Switch them around and reset the ECU. If that doesn't work call us (714) 847-2158 on Monday and we will go over the install and figure it out.

 

how do you rest the ecu

 

Same problem. Check and make sure the vacuum lines underneath the bracket are not kinked or pulled too tight. It will shut your boost down to abotu 12psi. When fixed you will run great!

 

If it feels markedly slower, then I would definitely be looking at your boost controller.

I would make sure that all of your electrical connections are well-seated. If you disconnected the connector to the boost solenoid and/or MAF during the air filter install process this would be worth checking. The boost solenoid connector would be the most likely (and could also be the boost controller vaccuum lines as mentioned in previous posts) culprit, although either could cause problems.

I have also heard of people pressing a cone filter too far onto a CAI tube until the tube bottoms on the inside of the rubber end cap of the filter basically cutting-off air flow altogether on their new CAI install. I don't think the RMR/EVO direct cone filter install set-up would allow that mistake because of the filter/MAF interface....but I don't know for sure?

Worst case scenario if everything seems to be in order, is that you can always re-install the stock box/filter and see if the power returns. I have had my air box out a couple of times messing with my FBC, and its a pretty simple task only taking about 15 minutes or so.

Good luck on finding your issue.

 

Thanks for all your help and insight into my problem. What i actually ended up doing was place the RMR bracket, on top of the stock brass looking bracket, so that all my meters and sensors would use the factory mounting points. I also wanted to do this so that i could keep the intercooler pipe bolted in by the fan. All i had to do was bend the vertical portion of the stock bracket to the right, to give proper filter clearance, and all is well. I did not undo any vacum lines, and i only took off the MAF sensor plug, but i did that before i unplugged the ECU. I left the ECU unplugged for a good 40 minutes, while i ran a few erands, and finished the install. I have re-checked everything and i can't see anything wrong at all. The only thing i can see that might be something of a problem is that one of the vacum lines that goes to the boost sensor might be too tight where it is tied to the facotry intake pipe. THis is a factory tie like a zip tie, and i can feel that the hose might be a little tight there, but that is about all i can figure out. When i put the battery terminal on after installation, i only let the car idle for a little while, about 4-5 minutes max, probably less. Then i shut it off, and then about 40 minutes later, i drove the car, and it felt dog slow. Power began to come back little by little, almost like a ecu re-learning thing, but could this be where i went wrong? Should i reset the ecu and then start the car and let it idle for a much longer period of time to let the ecu properly re-learn?

I love the kit, everything is very nicely done, and i know that the problem isn't with the kit as many people have had success with it, it's probably something really silly and minor that is causing all this headache.

oh well, tomorrow is another day.........

 

i too am feeling the lag of the RMR filter and i took off that gold factory bracket thing to open up room....i do not know what to do i am lost
