My B20VTEC dyno

Going to other parties to fix a problem someone else created does suck.
But after shelling out a wad of cash and not getting what you're after, then having 3589735 people say "WTF BRO, IT"S SHIT". Kinda makes you some what upset. You no longer trust the people who first tuned your car. Turning to someone else to find solutions.

Car was just tuned, it pulled bad power figures and the A/FR is all over the place, it drives like crap and goes like crap. All the evidence is there but at the end of the day. You're just some joe off the street and the person who tuned your car is master of the bloody universe. So whatever they say, is infallible. It's nice Mercury offered to fix the issues, shame other shops don't. Without charging you again anyway.

GL with the tune.

I still think taking the car back for another go is the best and cheapest solution.

I think a torque output graph would really identify the optimal VTEC switch point, as the hi-cams would be killing torque at such low rpm. The long stroke and >12:1 CR should see some very decent numbers achieved if the ignition timing and AFR mapping is cleaned up. The ITR camshafts should also be dialled in to suit your desired rpm powerbands.

I would be fitting a larger TB as well, the factory item would be restricting air flow at higher rpm. The low rpm hesitation would be caused by the loopy AFR's and the lack of torque(why the HP curve levels off)

Found out that my spark plugs wernt the right heat range causing the timing to be way off hence i wasnt able to get any more power up top.

What rpm was that 131Kw@wheels made at?

I was just reading all of this, don't know much about tuning but I like to read this type of posts so maybe I can pick up a thing or two from other people (I think that's why we all come here, to talk and share our experience with our cars), anyway I personaly think that this type of set up chould pull a bit more power, not because I know how to tune cars (I don't at all) but just by comparing it to some other cars with simular/same set ups (check some europian honda sites and forums, this tupe of set up is becoming very popular thing over there).

Anyway vlooks like it's gonna be cool ride, good luck with everything


This cought my attention

I take issue is with the criticism has comes thick & fast from the would-be & arm chair tuners. How this or that should be better.
& I don’t mean those members who are just voicing their opinion, that’s what this forum is all about.
I mean those who would engage the market for profit.

So are you saying that you are not in for a profit???

was making peak power around 8000-8200

Malenic1981, would you prefer if I was less cryptic?

If you make money from the automotive industry from selling parts;
But you don’t really have any actual tuning experience
Regardless of how much enthusiasm you have…
Without real knowledge & experience, you can only regurgitate the BS you have previously ingested.
If it were otherwise, you’d already be doing something about that lack of experience.
Hence the comment about the “Bronzed Stool”
(This is a bronzed piece of shit if you didn’t get it. Priceless, don’t you think?)

That said, If you’re not in it for any money & just an enthusiast.
Why would you take any offence from what I have said?
It’s not aimed at you & it is for your benefit.

Regarding the tune,
Though it may not be what we would do, the place has offered to rectify the issues he has with it.
That is fair & reasonable so I hope it goes well for him.

I'm not in for money at all, I'm no trader or anything close to trader but I think that you as a trader could be a bit more respectfull to us enthusiast (with or without knowelage). I think that your business depends on car enthusiasts and in some way we depend on you guys (in general, traders, works shops ect).

I have trader rating "0" so I'm not taking any sides or anything but I think there is better way of talking to fellow honda enthusiasts.

Sorry for going completly off topic

Malenic1981 - A better way of talking & not taking sides? WTF?
Say it nicley & it goes over your head, no one gets it.
Say it more bluntly & someone needs a saucer of milk ?
It's not about you - dur!
PM me if you've got more to say it's off topic.

Respectful? Sorry, after all the bullshit theories, I rather have a tuner thats blunt and saves me money in the long run than a quack with a sweet tongue trying to sell me something...

well guys...the car is goin back in for a retune on wednesday at Mercury..I rang them up today and told them of the issues and they were pretty cool about it and wanting to get it fixed asap...so ill see how this retune go...ill post up another dynograph when i do get it..and hopefully a torque graph as well...

How many years and how many cars that guy who tune your car done again???...is it like those Self Claimed thing?..Yea, like Adrian say, give that guy one more go, and if he screwed up, then get to some one who has more experience, at least tuned more than 300 - 400 cars...without much fault...(without much fault means at least the tuners are responsible and know what they are doing or care to explain any chance of fault if it were to tuned at its limit)

one thing, when people say "what setup they should use", can some one clarify the meaning of SETUP to me? it doesn't really make sense to me at all.

e240 at the and of the day they gonna take mine/yours or who evers money, and for my money I do expect a good product or job done to my car but also a bit of respect, if I can respect them they should respect me, it goes both ways.

master_bo_bo good luck with retuning

erm....bo bo, what intake manifold and TB you using?
