question from a noobie...what the hell is the OBD1 and OBD2 stuff about? what does it mean? what does a 91 accord have? and y do people swap them? thanks alot!

 

OBD-1 and OBD-2 are 2 different types of engine management.
OBD-1 is what you have, and was standard for almost all hondas up to the year 1996. then they switched to OBD-2 which is more concerned with emissions and such.

If someone were to switch from OBD-2 to OBD-1 they would be doing so because it is easier to tune and get more HP and TQ than you would tuning a OBD-2 setup because OBD-2 is setup for economy and is strict with power gains. get me?

True, true. OBD stands for On-Board Diagnostics and is used to repair/find out what is wrong when the power-train has a problem. OBD-2 is just more complicated and can more accurately diagnose a problem in/with the car. Its basically a tool that lets mechanics/tuners know what is going on under the hood

 

how do you go about swaping from obd-2 to obd-1

They make a harness that easily converts it. The harness it only like $75-100.
