Do you think its time to move this to the technical? Think its moved beyond my ranting now.

what mashimaro has given us is a picture of an elbow and asking us to say the girl is ugly. we need to look broader!!! we need to see more than one snipit before u can say this guy cant tune!

seeing the only thing there that i wouldnt be happy with is the torque hole at about 4500, but i say that assuming my AFR was perfect and i got a decent base/final gain
are you sure u dont have crossover at about 4500-5200???
u go out and push it and listen to the engine, check if at 4500-5200 u can hear the vtec solenoid click, then ull prob build oil pressure then high cam will propperly engauge?
at what point is vtec now? the tuner would have to of changed the point for tuning purposes....it does look like itll be at about 5200 rpm
7.2 as stated.
Why on earth would vtec be set at 4.5? We tried settin it at 6 and it was dropping.
After tuning cant hear vtec at all now. I'm onli takin it off the power fc hand controller.
BTW i was told to keep revs down if knock reaches 40 by second tuner. Second gear full hammer its reached 35? Is that getting close to bad?
it all depends on ur high cam profile, my h22 had a great tune with crossover at about 4500
im gonna give up and wait so im not the only one arguing a point here, will check back tomoz coz its time to go to bed and this aint worth it
poor you i would be PISSED !
what gear was the run done in?
how does the car compare/feel/behave on the road?
knock of 35 is OK, and means the tuner kept timing adjsutments 'safe'...
it doesn't look that bad to me... yah, there's a dip in torque at 4kish that's less than ideal, but I've seen much worse.
the jaggedness of the graph could really be something as simple as what the smoothing was set to on the dyno output. A dyno output will never come out super smooth... there's always a certain amount of smoothing done in the software make the output "pretty".
There shouldn't be any jump in power at 7200rpm(which seems awfully high to me to have vtec set to, but that's just me) or wherever vtec is set to engage if the motor is tuned properly. A jump in power at vtec means the car is making less power than it should.
What really need to be done to show the quality of the tune is for you to show a before tuning dyno, the after, and an a/f printout, not a shot of sorta part of one graph.
Also, having a dyno show readings after peak redline isn't that rare... remember, you're spinning a big heavy drum, and accelerating it. It's going to continue to increase in rotational velocity after the clutch is disengaged... this is called physics.
mashi's running toda C's amoungst other things if i remember correctlyQuote:

Feels and sounds like there no vtec.
BTW - what "software" was the tuner using? also - has the tuner tuned spec C's before?
if he was just using the hand controller to make adjustments, then there is less adjustability compared to tuning from laptop software...
