i am going to pick up another 4 door civic ex today in ny. it has an ls/vtec in it but the guy says he has a civic vx ecu on the car right now. he says the motor runs nice and quiet and i can compression test it and drive the car of course if i want. my only concerns are the ecu and how should i expect the car to run and drive?? i just dont wanna get fucked. i have an obd2 ecu for a gsr, if i plug that in will the car run?? will it run better than the vx ecu?? i know it will throw codes but i just need to know the car/motor/wiring/tranny are ok.. so please gimme some input on what to look for.. thanks
