The stock 2001 prelude has an OBD2 ecu? Why does it detune? Is there anyway of keeping it from doing that? So over time like the i/e/h will become worthless that's what yur pretty much saying?

 

yeah but you can always go to OBD1.. simple just buy a adaptar harness.. i ll get ya one for 185 shipped.

 

So.. I dont understand (I havent got my prelude yet.. but will very soon) so the OBD 2 detunes the car? means the mods you do will NOT work after a while??

I dont understand the concept of switching between OBD's yet.. but i will search on here for info on that..

 

Honestly it's not that big of a deal. All cars have it 96 and up...you can just pull the fuse on your ECU to clear the memory every week if you're that worried about it.

 

Heh, im not THAT paranoid.. but i dont understand how the OBDII system detunes the car?

My impression about OBDII was suppost to be a faster way to Diagnose Problems faster than the OBDI system.. Though I am still not every familiar with OBD at all.. since my car was a 89 maxima and didnt have to mess with anything of the such.
