i have a s200 series p28 ecu that has been tuned for a boosted b16a, i bought it off a friend which is what he had in his car, well i am about to get a 97 civic that is turbo'd with a d16z6 all it needs is an ecu, im just curious if i need to retune the ecu to get it to work with the d16z6, sorry if this is a dumb question im kinda new to the tuning and what nots

 

yes you will have to retune it
