I'm running ls vtec in a 5th gen civic and I think that It'd be best to run a DOHC VTEC del sol si ecu. however I'm not sure if it is obd1 which is what I need.As well as if i will need and special sensors that my block dosent already have. (knock sensor, crank position sensor, etc)thanks alot guys, this question as well as which wiring harness should I use are all i have left to find out. any help is as alwayse greatly appreciated because its all going down in a week. so again thanks alot guys and any knowledgable person please help-

 

um...

you want a p28 ecu, then you don't need to worry about knock.

get the Si harness? what is your car.
