Hi me and my friend just installed an AEM v2 intake on his 01 prelude ( has DC 4-2-1header ) . And after racing my car honest to god it made his car slower..... just alot louder. Is this supposed to happen i don't get it? you pay so much for an intake and it does nothing or takes away power... doesn't make sense.... has anyone else had this problem or simillar? would it have just been better to get a normal cold air?

 

Was the ECU reset after installation?

 

I was thinking of that... i did to it what i did with my integra to reset the computer... is it a different process? cause if it is that would explain it

 

No he was just not driving as good. it will make power, and i dont think when you put on a damn intake you need to reset the ecu...

 

check and recheck everything to make sure you did it right. check to see if everything is sealed tight so that there are no leaks. this might sound dumb, but did you check the intake pipe to see if it was clean before you put it on? my friend forgot to clean his out one time and it fucked it up.

 

yeah the pipe was clean and everything is done right... and i doubt he was driving wrong cause before our cars were the same and now i can beat him.... even if i have more ppl in my car... i don't get it it's really pissing me off... the only thing i can think of is that the v2 is in the place the short ram is and it's sucking warm air. I think plain cold air woudl have been better

 

the V2 is supposed to be cold air intake, supposed to go into the wheel well. CAI installation on 5th gens is a bitch due to having to hut a little spot out for the intake to fit its fat *** in the wheel well

 

But nowhere for a 5th gen is a v2 ever advertised as a cold air... and also it sits in the engine bay... it just tilts down a bit but the cold air intake goes right down into the fender... i think it's cause the v2 is such a huge *** **** it's too big to fit anywhere but there

 

Umm yea you have to frequently reset the ECU when you add bolt on mods like exaust, headers, intake to any OBD2 Vtec car. OBD2 Ecu's are bolt-on's have been added re-adjust the fuel-air ratio nullifying out anything you have done to this. OBD1 doesn't do this however. So basically within a week or so on a OBD2 ecu with bolt-ons the computer has readjusted itself back within stock standards. So the only way to defeat that is to get a whole new ECU, go OBD1, or reset the ECU daily.

 

My 98 integra gsr has OBD2 and i have a CAI intake and headers. I reset the ecu once and that was like a month ago and it's still as fast as it used to be.

 

i think that theory has been proven incorrect.
