i dont know if this the right thread but i have a 99 si with a 94 gsr swap converted to a obd2 running on a 96 jdm gsr ecu. ok here the problem ill be driving for 10-15 min then my check engine light would come on then the car would go in limp mode and start to bogged out. i took a car to a shop and the shop told me that the car knock sensor is not hook up. Does the jdm motor run on knock sensor? and do you guys think that might be the problem. i think i am going to try and change the tps sensor. what do you guys think it is? new to honda scene

 

any help

 

Yes a JDM OBD2 ecu will look for a knock sensor and the 94 obd1 Gs-R also has a knock sensor.
