OB2

[1337_Beemer]

I know the Faqs said that the OB2 was intruduced sometime in1995 or so, but because this is bmw, and they have high standards, is there anyway that a 1993 318i could have an ob2 hook up? if not how how much info could a scan tool get with an ob1? and are there any other scantools that could give me a good scan of the car? even if its not ob2??

Just ur guyses opinion 1993 318i 5speed 60k miles for 5500$? i think i can lower him to 4700$ if i give him cash, maybe more?

Also when i go and check the car out is there anything to look out for? that u guys know breaks in that edition and year of the car? what things should i be testing?

Can i also bother someone to do a detailed carfax report? I know lots of n00b questions but i really want this car, and i need to make sure i dont get my ass raped as soon as i buy it.

peak research makes a code reader and reseter. bavauto carries one as well.

Yes OBD2 was introduced in the 96+ versions in the 3 series. But why would you want to switch from OBD1 to OBD2 used . OBD1 is better and has less limitations. ( you can chip OBD1s, Not OBD2s. )

- I think the only reason they had OBD2 on the 96+ versions is because the 3 series have .2 more liters in those years. ex. 92-95 = 325i(S) -(OBD1)- 2.5 liters, 96-98 = 328i(S) -(OBD2)- 2.8 liters. 95 M3s 3.0L (OBD1) , 96-99 M3s 3.2L (OBD2).
Hope that helps. ghead

Thats not why... the reason why was for emissions standards... there are much more emissions controls on the 96+ engines. not the .2 L another thing that throws your theory off was the growth from 1.8L to 1.9L in the 318 series.

the larger engines was because of the ODB2 to get the same or close the same power in some cases more of the engines while complying with emmsions standards.

Just to add more clarity to the subject matter, OBDI is better with regards to performance due to it's lack of restrictions, but it does have drawbacks. One of the cool things about the OBDII system is that with the proper equipment, one can get an inordinate amount of info about one's car. I know there is a link around here that goes into more detail, you all should take a peak. The OBDII system can relay a ton of info. MPG, revs, accleration, average speed, this list goes on and on, very cool.

I converted back to OBDI strictly for performance as it adds an instant 30hp to the M52 powerplant.
