well i guess this is the proper place to put this but if not, please move it. i am currently doing a research paper on the "obd II" systems as a way to get this ghey research paper out of the way, and spend my time advancing my knowlege on somthing useful. now the problem i am having is i can find all kinds of stuff about emissions and all that good stuff, and i searched on the org and found mostly trouble shooting stuff. but i am trying to gather up some information for this paper. stuff like acctual articles i can site and what not. if anyone can help me out that would be great. thank you in advance.

sorry, after re reading that its not to clear. i am looking for information more on the performance end, as far as tuning and @!#$. thank you for your time

OBDII is was mostly an emmission upgrade over OBDI.

from what ive heard and seen, basically just requires 2 or more catalytic convertors.

as far as the performance end of it, its alot harder than OBDI. with OBDI, you could "chip" you vehicle alot easier. basically, most OBDI computers had an EPROM (Erasable Programmable Read Only Memory) in them. now by knowing what parameters to adjust, and having the Eprom burning accessories, you could mod your vehicle easily.

now with OBDII, you cant do it so simply. you need to get a tuner like SCT can provide or you need to have computer software and an interface cable like HP Tuners provides. rather than just reflashing a chip, you need to reflash the whole computer of the car.

now if there is an electronic transmission, you can edit those parameters with either OBDI or OBDII (i think).

there is alot that can be obtained with both systems, but OBDII is just more of a pain in the ass.

have fun!






Injection is nice but id rather be BLOWN!
