Yep he was wrong. I don't think he knows what he's talking about.

95 and previous models are OBD1, 96+ models are OBD2. The newest BMW's compuer systems are too complex to reprogram the software, who knows what version it is anymore. Am I the only one who likes older cars because they are more simple?!

Neither...1995 BMW's have a 20 pin connector under hood. I too have a 1995 325is (black)
That 20 pin connector doesn't determine whether or not you have OBD 1 or 2. It's simply there for diagnostics and resetting engine codes/service lights.

You have a '95 325 so you have OBD1

To answer that, I'm not totally sure...and I don't want to give you false information.

And thanks BTW :) I like it.


P.S. totally dig your signature :p

Nah Auto...I wish I had known this stuff before every buying a BMW. I think the 95 and older models are great, especially for tuning. I'm in the market for a 95 M3 :rock

so does that mean 325isbaby was wrong, when he said a 95 325 wasnt odb1? becuase i thought it was?

David
Well, since European cars weren't concidered OBD I, I guess I'm not wrong. [/b][/quote]
I don't understand what that means. Where did you get that information?

Even a Eurospec M3 is OBD1, why wouldn't it be considered OBD1? :confused

OBD in it's early stages was really only an American designation...Established by the EPA and CARB. German (as well as other imported vehicles) did not adopt the OBD idea untill it became standardized (or in other words required or you don't sell your car here kind of deal) in 1996 with the introduction of OBDII...BMW has been using a form of On Board Diagnosis (via 20 pin connector) for many years, but it is commonly refered to as BMW Diagnosis...same principal idea, a way to keep your powertrain/emissions in check.

okay then well maybe my next car might have to be a 325 instead of a 328!

Kev's FAQ addition explains most of this...


IF you convert the M52 back to OBDI you have similar power and chipability of the '95 ///M3 without the pricey maintenance, An ///M3 is undoubtedly the better car, but the aforementioned isn't a bad idea at all....
