ok i have a b16a obd0 in my 93 eg, im using the stock p28 from my single v. there is no knock sensor on the motor because it is obd0. i have had a pr3 for awhile but only used it on the d16, i know it was for a dohc motor but it pulled haha, but i threw a code with that ecu never checked it but im thinking it was a knock sensor.
i just got a p61 from my friends wrecked 93 gsr, does it read for knock sensor? and would it be a better ecu to run besides the p28?
sorry for the whole description but i want proper answers

 

are you keeping the car obd1 or converting to obd0

 

if obd1 chip out the p28 ecu and you should be good. If obd0 go for a pw0 ecu or the pr3
