Civic EG

ok, this maybe be a stupid question but still learning. what is a p28? i've searched but found nothing, only how to chip it. also how do i found out what ecu i have? got a 95 si. can i chip my ecu and should i chip it? like i said i'm still learning

a P28 is the ecu used in 92-95 Si and Ex civics. it runs the D16z6 vtec engine.

Chipping is a bad idea unless you really know what you're doing. Stay away from things you see on ebay etc. If you're using a chipped ECU, it should be done professionally and be ready to pay for some dyno time and a tuner who can fine tune a program for your car.

So unless your car is heavily modified naturally aspirated or boosted, chipping should not be at the top of your list of mods.

Pure gold.

to find out what ECU u have just look at the middle number should say something like P06, P07, P28 etc....
