if it's obd0 and it's just a daily driver the PR3 is great. The pw0 is just a waste of time, stock that is.
I have a pr3 for daily driving and a "chipped" PW0 for trackdays and the such.
If I had OBD1 (in hindsight I should have gotten in the first place!!!!) I would use something like a p72 and a vafc

P30 has datalogging, launch control, and more programs than a PR3 (although the PR3 does have a lot).
Looking back, I would have converted to OBD-1 also.

exactly
obd1 pr3's seem kinda rare.. and deff not a desireable ecu IMO

the obd0, 1, 2 depends on year of car, etc
unless you convert to obd1(you need - distributor, conversion harness, 4wire o2 sensor) then you are stuck with obd0ecus.

I ran the pr3, then the pwo. I liked the pwo more because it fit in the mounting location better. The car ran the same for me with both units. Ryan

yes but that does not mean you cannot convert to OBD-1

if you want to be smog legal in cali you MUST do an OBD-1 conversion

Yeah, if you want to be smog legal you have to be OBD1 or OBD2, but those motors cost more $$$$....

I do believe the injectors are of a different type, and need to be changed as well when converting from OBD0 to OBD1, etc.

Re: which ecu should i use for my b16 swap???? (milk)
To convert, you need: obd1= injectors, dizzy, conversion harness, 02 sensor (4 wire), and ecu. (I think thats it)
To be cali smog leagl, you need all mentioned, and a del sol, or similar intake mani. Basically it has to have the same format as the del sol, that way the ref can check proper vac. lnes, exc... Also a US ecu (obd1) is needed, they are hard to come by.

Yes the injectors AND their plugs ARE different, but you don't NEED to use the OBD1 injectors and plugs to convert to OBD1. You can keep your OBD0 injectors.
If you keep the resistor box wired in and leave OBD0 the plugs.
