Whats the difference between an OBD1 and OBD2, performance wise? why does it seem like OBD1 is more desirable?

 

n e 1?

 

functionality and rationality tests done inside the pcm

 

so, there is a performance difference?

lots of people that i've talked to are always like, "wut you running obd1 or obd2" i say obd2 and they make it sound like obd1 is a lot better..??

 

In OBD 2 the computer has the ability to moniter a lot more of what the engine is doing. In OBD 2 there are a lot of standards that go over all makes and models. For example the troubles go by the same numbers and the plugin for the computer is always mounted under the steering wheel. It is usually easier to cheat with a OBD 1 car because the computer does watch the emissions as closely.

 

obd2 has more sensors and the pcm can control things more quicker..obd1 has less sensors and the pcm is alittle slower but most ppl like obd1 bcuzz its easier to tune
