hey h-t i have a 97 civic with a b20b swap with p8r head when i did the swap i was running on obd1 ls ecu ran like c**p so i got a chi[ed ecu wich is runs realy bad when cold but somewat norm when it warms up so i was at my boys shop he had a obd2 y8 ecu or y7 but i ran good do idk im realy lost

 

Any check engine light codes? possibly O2 sensor. You need to get the right ECU along with the right dizzy and jumper harnesses.

 

well i do have the obd2a to obd1 jumper harness but wat kind of ecu i need cuz a ls one still runs bad

 

Did you the chipped e u tuned for the motor or just used the program on there

 

The LS ecu should run the motor fine, you must have something wrong. Wiring? what are your codes

 

no codes no cel
