i just swapped my civic with h23a bluetop, i have d15b vtec harness with po8 ecu,

i can chip my po8 with the right map, but what about the harness?! would it work?!

 

?! anyone

 

you can make the harness work. there are some good ecu chippers here on HT i know a few, let me know if you need there contact info

 

yes your harness would work, you just have to stretch a couple wires here and there(alternator, vtec, iat, etc..)
as far as the chip, youre better off tuning, if you insist on not tuning, www.kenji211.com makes good maps.. we had a b16 running running on a p28 with a stock b16 map on it from that site and it ran great and got good gas mileage..
