wtf is odbi/ii?

[llewellynbrandt]

i have a 98 323i, and i'd like to increase performance for overtaking and accellerating. whats the best way, (that wont fuck-up the engine) to go about it?

Oooh now there's a question thats never been asked on here before!

The general consencus for OBDII cars (yours) is that you need to "shark" it and probably change the air intake too, add a performance exhaust that you can fit your head in and away you go!

Try a search on chipping/sharking...there is tonnes of stuff in the forum

Hope this helps

'cos i'm thinking of gas flowing the head to up compression ratio, m3 intake and exhaust manifolds (if it'l fit), gruppem or similar filter charger and a ''noiseless'' performance exhaust, and the ecu thing. is it necesary to replace cams?

first u should learn what it is before u start modding.


OBD - 1 - anything before 1995
OBD - 2 - anything after 1995

OBD - On Board Diagnostics

OBD is pretty much government restrictions that a car has. OBD - 2 is harder to mod. but converting OBD-2 to OBD-1 is very much known to do.


im to tired to go on. if im wrong. correct me
