by a modded 2k vtech lude. he had intake and catback
I have greddy, y pipe and intake.

I installed the y pipe on friday, and figured it'd be used to it by now, but by 85ish, the lude had a car length on me.

My question is, how long does the ecu actually take to "learn" the pipe? I reset it this morning but it seems odd that i lost to the lude since when we raced b4 when i had only intake, he walked me by 1 1/2 to 2 cars. I figured y pipe would gimme more of a gain.

Since i reset, how long should it take to learn, in miles.

 

bump

 

5-speed preludes with headers (y-pipe?) etc... are pretty fast... they all had v-techs that last generation... 195hp stock?

 

he only has aem cold air and greddy catback 3 inch piping. its a 2000 and i think they come with 200hp

 

It is, what it is... don't feel too bad... sometimes it comes down to who gets the holeshot. You're an auto, right?

 

yeah,im a slushbox. I think a lot of it has to do with my 24lb 17's. He was running on his oem honda wheels with lower pressure

 

Probably... I sure felt my 29lb 18" Lowenharts when I had them on the car.

 

It is my understanding that our cars when @ WOT, don't use learned fuel curves. That it becomes an open loop. The ECU codes are during closed loop? So if thats true, when you hit that gas the ECU just give it at a certain rate regardless of what it has learned or what sensor errors it has.
