alright..i bought a 94 integra from a guy i knew. I wouldnt usually buy somthing like this but it was a great price and seemed everthing was done right. It has the lsvtec conversion plus many extras. he had a apexi vafc on it but took it off when he sold me the car to put on his new one. ran perfect, had perfect idle and everthing. a year later i put some new bearings and rings and while it was tooken off sent the head off to get a 3 angle valve job and seals and things replaced. now it has a very rough idle and starts smoking(black which means gas) around 4,600rpms(vtec comes on at 4,800). it has a mugen cpu. do the vafc save settings then when it sat there during the rebuild it reset and all i need is a vafc? or is it somthing else? i have tooken it to the dyno and is putting out about 20hp less than when the guy before me had it and i do notice it is running richer during those rpms(around 12.5 to 1 at the lowest point).thanks for reading all that and any replies.

 

either him or you did something wrong building/breaking in the motor...

how many miles are on it???

id get rid of the "mugen" ecu and VAFC in favor of chrome or uberdata and a good tuner...

 

see thats the thing with ls vtecs there like woman if u dont treat them right they wont treat u right not saying u did anything but the guy who had it b4 u probaly didnt that setup is tricky very tempermental u have to keep ur eye on it always!

If it ran correct on its original build its on you. All things fell apart once you tore down your block .

20 less ponies - more fuel= needs tunning ! and yes chipped ecu's suck

sounds like the build or break in to me too...and MOST DEF get off that Mugen chip...

 

the build is right, me and a friend who has been building and working on hondas for around 20years helped me do it. i broke it in properly also. its got about 93,000 on it.

Yet after the build its putting out less hp and smokes.....Im glad you think thats "right". The vafc should have held your settings, so its probably not that.

 

who did ur headwork...id take it to them...maybe the fucked somthing up when they did the angle job and ****. doesnt suprise me that its running rich

 

get a p28 with a hondata s200... that's my setup and it's working without problems.

 

a local machine shop did the head work, i was kinda wondering if maybe there was a cracked valve seat or somthing that they didnt see. yeah i definitely would love to get a s200 but dont have the funds right yet

 

good luck to ya!

 

damm i havent placed my 2 cents around here for a while...
did you upgraded your injectors?
