ok i have a 93 dx hatch with a jdm b16 now i have a p30 ecu but it is the small one my friend has a p30 ecu in a 93 integra with the same motor just a cable trans. and his ecu is normal size whats the diff ? also would there be codes if it was a auto ecu... i do have a code 1,and 41 i kno 41 is o2sen but what is 1 ?????

 

bump

 

Your smaller one is a JDM P30. The normal size is a USDM P30.

 

i kno it was a jdm but is there any other diff.. or is one better that the other or are they the same really thats for the help

 

i done that same swap n my 92 hatch and mine threw code 1 thats oxygen sensor #1

 

by o2sen one what do you mean cause there is only one in the car ??

x2 not sure why but thats how it is. I don't think it really matters

Code 41 is Primary Oxygen sensor heater. and Code 1 is O2 sensor.

Basically replace the O2 sensor

 

i hve a jdm b16 with jdm p30 ecu, not sure if the USDM ecus have a cut or not, but my JDM p30 cuts out at ~185km/h.

i would like to know if the USDM ones cut out..
