i have a 89 honda civic hatchback with a b16a motor swap with a chipped pr3 ecu so vtec kicks in at 4700 rpm. when vtec kicks in the motor loses power and kind of hesitates until it pulls through at about 5300 or 5500 rpm, then it seems to run fine. i was wondering if anyone has ever had this problem with their b16a.

 

wow please search before u write this kind of topic, this has been covered NUMEROUS time....lord...

kill me

 

wow, thanks dude, ur pretty helpful there. thanks for pointing me in the right direction

 

yeah there are a bunch of **** on here that dont help, just want to hate on everyone one that comes here. wish i had an answer for ya.

 

check your oil.

 

your engine isnt tuned or built for that.

unchip your ecu or set the vtec at 5500.

who chipped your ecu???

 

somebody correct me if i'm wrong but when u lower your vtec cross over then your timing needs to re done to compinsate for that.

 

my buddy who went to electronics school installed a socket. i don't have the stock chip, i was wondering what rpm the stock vtec kicks in at. i have several other friends with basically stock b16a's also with chips running vtec @ 4400 and 4500 rpms and they don't have any problems with their vtec.....?
