k20z3 stage2 cam tuning help
[IMG][/IMG]i went today and dyno tuned my car on a dyno jet. spent about 4 hours on the dyno trying to tune the car. current setup
injen cold air intake
hondata img
throttle body spacer
ported rbc manifold
rdx injectors
bp racing stage 2 cams/ valve train
dc race header
megan mid pipe
magnaflow axle back
turned out very disapointing
207hp and 151tq
horrible numbers for the amount of mods, attatched is a data log of a dyno run this is what the car ran over and over again, couldnt get anything else out of if.
if anyone has any help to knowing why this is running so poor?
the ecu doesnt seem to recognize load properly?
also the car pulls the way it should under 3/4 throttle but wide open the car just doesnt go/ its like the vtec cross over is not switching over smooth.
is there something i should look for in the datalog specificly.

Re: k20z3 stage2 cam tuning help
what are you tuning with??? hondata??? looks to me like your DC racing header is holding the engine back. Also what size is your exhaust....any info on the block??? post some more details about the build.

Re: k20z3 stage2 cam tuning help
this is a stock k20z3 bottom end with supertech valvetrain and stage2 bp racing cams. i know the header isnt the best but this setup has mad good power for lots of people, i know its the tune but im no tuner to know how to fix it. im using flash pro to tune it which is almost the same as kpro very similar the files are stil .cal files. i just know that this should run much better then it does. vtec doesnt engauge smooth it seems like it has a hard time crossing over and sounds like knock. maybe the cam angles are not matching up well enough at the cross over. idk i can sent anyone the datalogs and calibration if someone will take a look at it
