Hey

I got a 62 Nissan ECU that has a SPL Computer brain in it

Central 20 (serial # 104374)

You guys know if its big difference compared to stock? or if its any good at all with that chip

will this be compatible in a 98 180sx s13 sr20det black top(i think its compatible but just want to double check?) I think it uses an E5 for that motor.

Thanks

enthalpy;  
the ecu’s are interchangeable int he fact that either will run your motor. however. the O2 sensors are not interchangeable and will cause poor gas milage. you should run the O2 sensor that matches your ECU.

skinny for 62/63

fat for E5.
