heres the deal i go down to try to get my car tuned and we get everything setup,
so start trying to make pulls on the dyno and everytime the car gets over 5k it falls flat on its face and its only making like 120hp and 130tqA(will post sheets later), it just sounds like its popping real bad, I put brand new ngks it, changed rotor ,cap, even another distrubitor that came off a 500 hp car, and still the same thing, the a/f was within range, the car runs fine, no vacum leaks, did a comp test everything is within spec, injectors only running in the mid 70's, me and locash were puzzled in what the hell can it be the issue? lookin at the dyno graph it looked like a ignition problem but then did all that **** and same result, so lets hear what everyone has to say
here is the mods
b16a2 w jdm b16 cams
drag manifold
t3/t4 59 mm .70 a/r cold side/ .48 a/r on the hot side stge 3 wheel
jrc 8in ic
dsm450's
2.5 dp to 3in exhaust
hondata s200
turbonetic evo wastegate 7psi spring

the gap on the plugs might be too big. Is it happenin when vtec kicks in?

importfan2

gap is set at .30

s2kdre

try lower my tuner gaps them at .22

importfan2

i've never heard of n e body running them that close but no two motors are ever the same, ill check wit my tuner and c what he says

importfan2

Was base ignition timing set ?
What amount of ignition timing for amount of boost were you running ?

importfan2

he set the timing with the hondata, i dont know exactly off hand but ill ask him later and find out, the car isnt running lean

Just came back from the dyno once again, reset the gap of the plugs down to .22, still the same crazy misfire,tried rc 550's ran a little better but still same ****, even pulled 10 deg of timing and still same thing so im lost on what else to do

what map sensor are you running? If other than stock, please ensure that the 3 bar map sensor that you're using isn't a 2 bar map sensor, for it really throws the Hondata off a bit so that it seems as though it can't boost well.. verify the part number.

importfan2

still runing the stock map sensor dont need a bigger one as of right now since im keeping it under 11psi

importfan2

my next step is to replace the cap,rotor,wires, and put in some gsr cams

i have a B16A2 in my hatch that is turbo'd mine is fully built but i ran into some misfiring problems as well, but mine was occuring around the 300 mark.

i tried all the same crap, new dizzy, wires, plugs, gas. i did however gap myplugs at .22 like above said, if i gap them at .25 it goes crazy.

what plugs are you using?

samll bore motors dontl ike timing but for some reason my timing is insanely high, so it may not be that you need to pull timing you may need to add, mine is in the mid to upper 20s before the boost retard

importfan2

im running ngk's the ones that r a step colder by one range
