obd-2 by the looks

[jansenrw]

so sorry guys,

dc2 itr 2001



As for the fitting, its for ordering a 2.5" cat, he needs to know obd1 or obd2

[jansenrw]

yeah, looks like obd2, can anyone triple confirm this??? Thanks

[chuck]

yes stock ecu 2001 dc2r odb2 triple confirmed.

[tinkerbell]

OBD2a or OBD2b????

[kavehman]

i have no idea what obd we are, but i know that there is no sensor after the cat, so really it doesn't make any diff if you run the cat or not as far as the ecu is concerned.

But im sure the epa would have a word or two about it.

[TODA AU]

AUDM is OBD2a

[jansenrw]

hmmmmm... so i take it there are two sensors, one near the base of the header, the other in the cat??? is this correct therefore obd2. If there is no sensor after header obd1 correct???

So in theory, i should see two sensors, one in header the other in the cat...

Please correct me if i'm wrong. Thanks

jansen - read above

Did some looking around - can someone answer this for me .....?

Apparently all US cars after about '96 have an OBD2 diagnostic connector (shown below) , whereas I've never seen one on my DC2R... where is it hiding!

[BlitZ]

audm dc2r have obd2a
99-00 ek9 obd2b
AUDM em1 obd2b
audm ek4 obd2a
99-00 dc2 should have obd2b

[tinkerbell]

99-00 dc2 should have obd2b

um, the Type R replaced the DC2?

only the DC2R or the DC4 were available from oct 99+?

Back when I was ecu shopping, was impossible to find the correct answer.

But yep it's OBD2A
