i am running around with b18b1 in my 89 civic hatch untuned hondata s100 so i was wondering if i tune my s100 how much diffrence would it make? is it worth the 150 an hour to tune it. how much more power would i get out of my car? it seems slower now than when i was running my other pr4 ecu with ebay chip i olny ran that bc it was free but i need to know is it worth it what it will do and one other thing. i dont have a o2 sensor plugged in right now so should i do that? would it make my car run better and it would have to be a 4 wire o2 i jsut have gont around to it. i need some help so can yall plz help out.
