OBD-I or OBD-II

OBD-I or OBD-II Which one is better? And why?

[wild.irish]

i'd say, obd-II has more diagnostic tools available. i mean ready, out of the box. if you'd want some data logger, you could buy one for obd-II, but you'd have to do something yourself for obd-I
otherwise, it's a knock sensor that's missing in obd-I, and some other minor things, not sure really.

Stick with OBD-1 or 0. More mod friendly.

[MirageZ31]

Thanks and another question. How hard would it be to convert OBD-I to OBD-II?

[wild.irish]

many people talked me out of it

[MirageZ31]

More mod friendly meaning?

[MirageZ31]

This is going to be a boosted B18B engine and I was just wondering which OBD would be best for it

OBD-II is newer and more advanced, but it's purpose is to please the EPA, not the driver. OBD-I has less sensors to go bad and you can use Hondata or Uberdata to make your own program for it. Given the choice, OBD-I is the way to go.

[Skaterkid]

OBD II is an enviro nazi. Stick with I

You still can Chip a OBD0 if you have Ubderdata...hondata have no clue...but it i was you randy, go OBD1 and get the jumper harness to covert the OBD0 to OBD1...or you can buy the clips from honda and make it your self, if your going to use it as a HW assignment for DADC...and weston is right when OBD2 and OBD1... they have purposes for EPA and Tuning.....

If your engine is stock or near stock, then it doesn't really matter, but I'd go with OBD2 because it has more diagnostic functions. If you are modifying it and need to change the fuel/timing settings, then you should use OBD1 because it can be tuned with Hondata or Uberdata and no piggyback controller. Putting an OBD1 ECU in a car that originally came with OBD2 will cause you to fail emissions in some states, not sure about CO.

it will pass in colorado....

[rmcdaniels]

Damn, I need to move to Colorado, it doesn't get too cold up there, right?

lol

[MirageZ31]

Thanks for all the help everyone. With all the information I have gathered and that I'm going to boost it, I'm going to get the B18B1 the OBD-I. Hey Shu any parts for this motor?

[V8SpankR]

With DSMs OBDI was much better than OBDII for reasons that were earlier stated like throwing mods at OBDI didn't throw CELs as readily and when hooked to a datalogger the OBDI logged at nearly 60 samples per sec vs OBDIIs 20 samples per sec max.
