hi
what would happen if i install a OBD1 ECU on a OBD2 car ?

i have a genuine SPOON SPORTS P13 ECU (not just the chip) but its OBD1 and my 96 BB4 is a OBD2

the pin from the OBD2 prelude are the same as the pins from the SPOON SPORTS ECU and i installed it without a OBD2>OBD1 harness

the car started normally but i felt no gains it drives normally but vtec still kics in at 5000 and the rev limit is still 7800 RPM

 

u can put an obd1 ecu in ur car but depending on ur state if the car is obd2 and u have an obd1 ecu u wont pass emissions at least here in nc

 

im dont interested to pass the emissions i just want to know why i feel no gains vtec is still stock and the rev limiter is also stock

could it be possible that i bought a fake ?

 

here you can see a picture of it


fake or real ??

 

anyone can put spoon stickers on there. And an OBDI ecu will not connect to an OBDII harness without the conversion. U got scammed.

 

1.i dont know for 100% if my car is OBD2 i just think that is OBD2 because its a 96 BB4

2. i´ve payd nothing for the ECU it was in another JDM BB4 that i´ve just for spares and the seller dont knew that there was a spoon ECU inside it was maybe installed from the preowner there was also a SPOON sports VTEC controller in the car

 

well in the US, 96+ is OBDII

 

so maybe the JDM 96 is a OBD1 ? and just the USDM are OBD2

i know that 96 EDM Preludes are OBD1 and 97+ EDM preludes are OBD2

 

i dont think spoon had an OBD2 ecu but im not positive. but regardless an OBD1 ecu would not plug into a OBD2 harness unless your car is a 95 lol
