Obd 3
 

my buddy has a 2002 civic and he wants header. but i heard OBD 3 learns your mods after awhile? is that tru?

is that a problem?

I thought the newest was still OBD-2(.5)?

There is no such thing as OBD-III. And yes any car with an ECU will learn certain mods.

It is called CAN (controller area network) and yes the CAN system remaps everything for mods

just pull the positive cable off your battery for a while, put it back, and start the car with nothing (radio, A/C) running. After 5 minutes, everythings remapped appropriately.

I do this after oil changes/tune ups/engine modding (when I'd throw an air intake on that bitch :p)

I'd like to try that, but it would clear my V-AFC out. That would suck!

Yep, sucks when you have to take the battery cable off when you have a S-AFC. I wish they built some type of back-up battery into it that saved everything.

so what do you do when your tuned with that?

my V-AFC keeps its settings when i do a ECU reset
