of 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

 

All of the ECU's from DOHC VTEC motors use/look for a knock sensor. If the motor has the sensor on it you only have to run 1 wire to hook it up.

 

my motor does not have a knock sensor.

 

The stock P28 is not sufficient to run a DOHC VTEC motor. You'll either need to get a knock sensor or have the P28 ECU chipped to DOHC VTEC specs.

 

damn i was really hoping i could use the p61 but oh well i can chip my p38 to DOHC specs, but i can also chip the others to lose the knock sensor right?
