what up everybody . i got a fully built allmotor LSVTEC (b18a bottom , b16a head) 97civic 4dr , motor has about 8000km currently tuned on hdata s200 .. problem is the car has this bog when shifting quick like a sputtering type then it picks up,, car is currently tuned for 7500rpm (for now ) i've changed my o2 sensor as my previous one was shot... it seemed to have helped out abit and i also get reallly shitty gas mileage , plugs oil are fresh,, everyone tells me that i prolly need a tune, car made 179whp at 7500rpm (powercurve was straigh and climbing) set it to 7500 since the motor was on breakin lol

any input is appreciated

 

know where your af/r's are?

 

not sure i got the sheet in my car somewhere.... all i know is the back of my trunk/plate is full of black carbon,,, its like black dust.. it rubs away easily with my fingers.

 

help this guy out

 

Check your plugs they fouled out?

 

id say swap it for a k series ha

 

i wish for the K, it's the way to go these days for true n/a power,, the plug are a lil dusty (black) i'm gonna get it retuned in 1week .. hopefully this solves the problem !
