ok still cant get my car to run right. i got a ecu its a p28 and is supposedly "chipped or tuned with HASPORT" with i never heard of them doing. here is the problem: i got a b20b block b16a2 head and a p28 ecu. timing is set and all vacum hoses are hooked up correctly. when its idling it sounds like its missfiring but its not its more like kinda boggs a lil. when i drive it up to like exactly 4k rpm it pulls really slow after 4k it goes good, it seems like the same thing when i had bad spark plug wires on a integra it sputters on low rpms and goes good on high, i got brand new platinum 2 plugs and brand new wires. anybody ever had a anything like this?
also does anybody have a chipped/tuned ecu that i could borrow and just see if that fixes the problem? because i dont know what it needs anymore lol.
