Need some help here people.....A friend of mine purchased a 93 Civic with a b16a2 along with I/H/E running on a Turbo OBD1 GSR ecu (Don't ask me thats how its labeled) Anyhow its running really rich and I was wondering since it already has an OBD1 ecu could a chipped p28 work with it if not better?? Anyway I could find out b4 purchasing a P28??

 

yes a chipped P28 with a mild program should be much better then what he has (at least from the description you gave), check my sig . or if the P72 is socketed he can simply just buy chips (check sig again)

 

yes, will work better in fact

 

do you know if it will be a plug n' play??

 

if it was plugging into the gsr obd1 ecu, and the motor is obd1 then yes of course
