What is the stock ecu that comes in the JDM B16A? I need that ecu..

Mike

 

OBD1 - P30
OBD0 - PR3 I think

 

does it have to be a jdm ecu? are the jdm p30s diffrent than the usdm p30s

 

fuel/ignition maps are a little different. and the JDM ECU doesn't have the ability to read a few sensors that the USDM ECU can.
Honestly not a huge difference, other than price.

 

if i have a jdm motor woudlnt it be best to get the jdm ecu tho?

i have the jdm b16a

 

bump need to know too

 

you want to get either a pr3 or a pw0 ecu. I think that the difference between the two are the pw0 is from the integra xsi and the pr3 is from the crx sir.

 

why do the jdm b16as all come with p30s?

 

comes with the p30.

 

what is the diffrence between the p30 and pr3?

 

P30 will plug into a 92-95 civic (OBD1) - there are OBD2 versions though
Pr3 will plug into a 88-91 civic (OBD0)

Ideally you want to pair a JDM engine to a JDM ECU, but if where ever you are requires emissions testing then you may not be able to run a JDM ECU.

 

mike.. thank god for sc..lol their more worried about real crimes and not cars

 

Yeah, i guess im still slightly confused. The date stamp on my motor is 93, which means it was made in 94. So if i have a 94 JDM B16A motor what ecu do i need to use? A pr3 or p30?

Mike

 

Well, if the motor is going into and EG, get a P30 or something like a chipped p28.

Also, to confuse you further, there is an OBD1 pr3 that came on the 92-93 integra xti which should work also, but rare to find.

stamped 93 means it was made in 93, the car it was sold in was sold as a 94 model year. It came with a P30.

shhhh don't confuse the boy. lol
there is a OBD2 P30 also. (96-97 DelSol)

Like SVOboy said...
If the chassis you're putting the engine in is a 92-95 civic then you want a P30 or a chipped P28 with the P30 maps in it.
If the chassis you're putting it in is a 88-91 civic then you want a PR3 ECU. Unless you want to convert the car to OBD1... then you want a P30.
If the chassis you're putting the engine in is a 99-00 civic then you want a P2T ECU.
If the chassis you're putting the engine in is a 96-98 civic then you want either a OBD2a to OBD2b harness and run a P2T ECU, OR a OBD2a to OBD1 harness and run a P30.

confused yet?

 

I think i got it..
