well guys im back , ijust bought coldair intake AEMfor 40 bucks i think its a good deal . wath do u guys think? well another question some guy tell me to get a ecu P28 i never heard about these before i need some info about these anyone knows is its good for my si 2000.................

next it will be headers and catback........

 

a p28 ecu is a ecu off of a 94-95(not sure wat years) civic ex.. its a sohc vtec computer.. people like to run a p28 because its easy to chip and tune.. obd2 computers cant.. also it looks for less sensors.. like the second o2 sensor and the knock sensor.. if u plan on gettin a p28 u will need a obd2b to obd1 jumper harness which ebay sells for cheap.. well thats all i can think of on the top of my head..

 

you should also plan on not passing inspection after losing that 2nd o2 sensor....

 

I think you have to have the ecu reflashed to run a dohc vtec motor.

 

the only benefits that this opting offers is greater tunability. i would HIGHLY NOT reccomend this if you have such minor modification. most stand alone ecu systems are used in boost applications and heavily modified NA motors.

 

SO SHOULD I KEEP THE STOCK ONE
OR ANY OTHER ECU
GOOD FOR MY CAR

 

What is mods are on your car? If there isnt forced induction or a built N/A motor then keep your stock one. Besides you will be able to pass smog with your stock ecu.

 

THE ONLY THAT I HAVE IS COLD AIR INTAKE
HEADEERS IN A WEEK ALSO CATBACK

 

keep it stock. you dont need it at all. unless you throw cams in it. add higher compression pistons, boost (supercharge or turbo) it is not necessary to have a stand alone programable ecu.

 

Yes what he said. Even if you get cams dont worry about it.
