any other dc5r (k20a2) owners out there with the following mods if you do can you post what your kwatw before and after the tune. I just got mine done it seems slightly lower than usual especially with the current mods compare to some of the other owners out there with the same mods.
exedy clutch
stage 2 lighten flywheel.
pod filter
headers 'hi flow car ' 2 half inch straight through
rbc bored to 70mm
70mm throttle body
kpro
124kwatw before the tune.
138kwatw after the tune.
Wow...
should post up dyno sheets of both before and after runs
interested to see thruout the rev range
not just peak output

I hate to burst your bubble but I would bet even with a dead standard motor and just the Kpro you would of made almost the same power.
You you need aftermarket camshafts and supporting hardware as well THEN tune to feel anything worthwhile IMO
What brand header? Is your 'pod filter' a short ram? as in its in the engine bay?
With a good header, 3" exhaust and a proper cold air intake you should get the magical 150 atw with a good tuner. Also take into account different dyno's read differently, Since you got it tuned in summer that wouldn't have helped especially if you do have a sri.
Ben I wouldn't say that for k series, bolts on and tune going from 110 to 150kw would be very noticeable.
what fuel were you using? bp 98? shell 98? caltex 95?
what was the ambient temp?
what psi were your tyres?
what size were your tyres?
maybe try a hi flow cat instead of a hi flow car, might help as well.
Hi flow car is best. That's why he's tuning to add flow
LMAO another Honda owner doing IHE tune and facing disappointment BAHAHAHAHA.
IHE is not enough to Justify the cost of tune + ecu on a Honda. Learn this. (this should be put on a sticky - could be saving new users some cash)
Btw clutch/flywheel type has nothing to do with power gains OP.
Also to the midrange argument you guys have fkn get real, if low and mid range matters to you than NA VTEC isn;t for you.
Fuk up amant.
OP what where you looking to get? Really nothing you have done to the car is going to make any significant diffrence as you have now found out, what you have done though is set up a less restrictive intake and exhaust but clearly in the stock configuration these aren't that restrictive on a stock engine, once you get the engine making more power then these mods will come it's there own, also look into a proper intake.
Lol the profanity. The truth hurts.
OP ill also be honest with you mate. 70MM TB on stock engine..... whoever is tuning your car is just selling you shit you dont need.
True , this example gained +14kw atw from standard map to "tuned" - not a waste of time but let me suggest that with only breathing mods - this is a peak power increase and not a noticeable useable torque increase. Hence with this extra "peak" power the guy won't be feeling a difference at the 1/4 or track. Yes , on the street he will feel a booBAAAAAAA stronger but that's it. Having thrashed both standard ep3's/dc5s vs breathing mods and tune there isn't a difference in pull.Quote:

TBH I think having a hondata early is a fantastic thing. The information available to is invaluable but on a stock engine with bolt ons you just arnt be winning race wars, that said would be good to see the curves rather than judging on peak alone.
Mid range is always important, you should now this being a turbo guyQuote:

Sure you can look at it as its a mod your gonna have to do anyway, but its paying for the car tuned over and over again, by the end of the build a good amount will
have been paid to your turner who's gonna be laughing all the to the bank. Do it once do it right.
Oh I know how important mid range is, but when I buy a Honda. I buy a Honda for its screaming top end.Quote:

Very good gain this. Tell me where to line up to have my wallet raped pls.
Like benny said, its only gonna be for butt dyno feels. No real gain that matters.

just for you ben look at that mid range
I will back ben up on this. Stock Honda Engine with IHE, ECU + Tune is not the next move.
Its braking and handling.
Oh wow is that wat mid range un tuned looks like. It really does put the transition from low lift to high lift soo much smother.Quote:

I still wouldnt spend 2k just yet.. save up for cams atleast.
facepalm
Na mate cost of Kpro and turner time is not worth still just with I/H/E
I'd still wait till I have enough for atleast springs and cams.
Cos whats that... $1200 cams and springs $500ish.
Will net a much better peak is what we all really are chasing when we tune. Unless your gonna be left with asking for more.
I should also note, this sort of improvement will been seen across any stock ecu being tuned, cos manufactures are conservative in their tunes.
Lol op
Several people have already explained this to you, including the guy who tuned your car lol...
I hear what your saying and I'm not advocating for tuning after every mod, I'm saying having the capacity there to time when the time comes and having the hondata installed early with the stock map for diagnostic purposes is a good thing.Quote:

Tune is well worth it imo. over 20kw gain in the midrange, id like to see cams give you better gains than that without going high comp pistons.
and theres no difference in paying 1k for an ecu now or later, youre still going to spend money on it. the only difference is paying for another tune down the track if you decide to do internals but whats another $500 1 year later.
OP, you still havent revealed what header and intake you actually have....also dont compare qld dyno figures to nsw, we like to leave the air temp sensor on the wall rather than in the hot engine bay
Killa's correct solid midrange gain of almost 25% where most of ur time is spent. Dyno graphs are like silicon ****, they look great but dont reveal the true performance. Ive seen a 6kw diff just from diff profile rubber/camber and hotter temps. :cool:
