How Do I Know...OBD?

[Magik Si]

How do I know if my 90 Civic Si is OBD-I or OBD-II...I'm just starting to get int othe "electronic" learning of my car and am wondering...this is the "brain" of the car so I want to make sure I'm mind melding with the right equipment.

it goes by years...

88-91= OBD0 (technically it is a version of OBD1, but its generally called OBD0)

92-95=OBD1

96-00=OBD2

[Magik Si]

OBD-0??

Weird...never even hear that one before...so...if I bought a "scanner" would it be for OBD-1?

Jason

no it'll be odb0 like he stated earlier, unless you want to convert your car to odb1 or odb2.

[Magik Si]

Is there a way to verify what it it "actually" is? For example is it "marked" on the unit somewhere? Is there a way to tell...want to know for sure so I'm not starting blind...

I'm pretty sure that only OBD2 and up can be scanned...OBD0/1 are not all that sophisticated

Dude, it's common knowledge that 88-91 civics are odb0 92-95 are odb1, 96-98 and odb2a and 99 and up are odb2b. the scanners only work on odb2 cars.

[Magik Si]

Ok...this may be a dumb question...but...

Obviously OBD-2 is better than 0 & 1...so that said, how difficult is it to convert my car to "2" from it's existing "0 but sorta like 1"??

Who said odb2 is better that odb1? if that was the case why does hondata only deal with odb1? to convert to odb2, you need to get the conversion harness from locashracing and an odb2 ecu.

Dude...obviously it's not THAT common knowledge because I didn't know it...AND like I said I'm JUST beginning to learn the 'electronics' of my car...
If the scanners only work on obd2...then why can you buy obd1 scanners??
So what is the primary difference between obd0 and obd1?? And is there a "better" thing to have?

Why do you need a scanner anyway? you can check any codes with the jumper harness by the ecu?

HUH?? I have no idea what that means?? I don't want just codes...I can get those by counting the "blinks". I want what Honda charges me $57.50 for! (and then tells me nothing by the way).

alot of dumb shit is being flung around this thread so lets clear it up.

you can only buy scanners for OBDI and OBDIIa/b motors. they have a connector under the dash where you plug the scanner into, there is no scanner input on our OBD0 cars.

OBDII is hard to convert to, cause you need to add extra sensors to the motor, as well as a new ecu and alot of wiring. Higher OBD's are better cause they tell more as to whats wrong with your car, its easier to pinpoint problems. they are also alot easier to fix, most problems can just be connected to a laptop and adjusted.

THANK-YOU!

Now...what is the best way for me to "learn" what does what "electronically" with my OBD0 car?
