well i had a 12.0.1 cr motor that made 237whp running out of inj on e85
that motor droped a sleave and i started over w a new set-up very
similar at 12.0.1 w the same cams............

the new motor is running huge inj 88occ the old was 450's so i know i
have enough fuel and the issue on the dyno wasnt fuel....
also the new motor has itb's and a different header


the new motor w itbs and big inj's beat the old motor hands down
from 3500-5500 it some aeras by as much as 40whp more.
you here vtec enguage and it is pulling good then just breaks
up horrible and misfires and doesnt make any more power..the curve is flat doneall the way till 8000rpms..
we replaced the plugs (copper and irdiruem)and the coil on the dyno and found no change????

my tunner suggested make sure vtec is enguageing at the rockers
the solenoid is working properly and the motor is 100%in time...
oil psi is very good as well...we tested it at the head even...........i dont think it is in the head
but i did pull the cams and inspect and found nothing.....i tried the air psi test to enguage vtec and the resulst were
incunclusive....on the dyno we were perty sure it wasnt compression related but i did do a compression test and all cycls were good...
it made 229whp on one pull,, we know it had compression.....also a caviler dynoed before me at 200whp and he ran a 13.4 at a 2600lbs race weight
so i dont want to here any bs about its just a high reading dyno....

i have ordered a distribor from honda too see what happen's
any suggestions.....it did make good power w this set-up it is
just a misfireing shitty pull over 5500rpm.....but below it just
smoked the euro R combo i had before so i belive there to
be alot left in this motor at high rpm if it made 20-40 more hp
in the mid range if it could just keep that going it will be a faster
car than before that is why i am dissappointed and it's misfireing lol


we tried many a/f cures and saw the changes fuel is good
ign changes on the map resulted in little changes that is
why i belive it to be spark related......help me quit spinning my wheeles?????
i dont think it is the tunners fault the graph is perfect below 5500 then
gets all choppy so i would think if he can tune down low he can tune up top???

 

did u add timing when and where it started sputtering

 

yes we added timing and took it away and nothing changed much
ooo it is h22 motor as well lol
