Teach me about ODBI/ODBII :-) Difference?
So I'm looking into getting a 2nd gen B16 within the next 3-4 weeks...and I need to know about ODB stuff...
I know ODB2 is hard to chip making ECU epgrades a pain in the ***...
So do I get a motor that is ODBI? what does that mean? It has ODBI sensors on the actual engine?
Thanks

Since you car is a '98, I suggest getting a motor that's from a '98-98.
Ok now here's how the OBD system works with Civic's;
-'92-95 OBD 1
-'96-98 OBD II (version A)
-'99-00 OBD II (version B)
Now, all OBD II ECU's can NOT be chipped. Only way to run a chipped ecu is to get an adaptor harness that'll allow you to plug in an OBD 1 ecu into your stock car harness.
Main different betwen the OBD 1, and OBD II A and B systems is that the OBD II have more sensors and more emissions equipment. As well, OBD 1 vs OBD 2 motors thery use some different style connectors, especially the ECU. (they are not interchangebale w/o adaptor harness)
For your ride, using an OBD II version A motor and ECU will drop in w/o any problems.

Thx...but if I wanted to chip the ECU in the future??? Would it just be easier to get a ODBI engine and ecu? or should I get a ODBII engine and ecu and if I really wanted to chip it I would get an adapter and new ecu?

get an OBDII engine and ecu.
if you wnat to chip it later. you just need a converison harness and the equivalent OBDI ecu.
it is possible to chip OBDII ecu's. it's been done, but costs way too much. the little electronic parts needed total over $1000 USD

ahhhhhhhh...so if im DEFINAtely planning on getting an ODBI 'chipped' ECU...then i might as well get the odb1 engine because...if i get an odb2 engine...the extra sensors wont be used with the obd1 ecu anyways...right?

i wouldn't put an OBDI engine in an OBDII car. generally going backwards with swaps is not a good idea. everything needs to be re-wired .. you're looking at alot of $$$$.. if you wnat OBDI, get an OBDII engine and get a converison harness with an OBDI ecu
