ok, im new on here and from UK. ive got a 1999 Uk spec ITR with a Supersprint manifold, Tanabe SMR exhaust system and an ITG Maxogen induction kit.

this is the dyno graph i got, but does it look ok?? afew ppl over here in uk says it looks good, other have shown me theres and they think that theres something wrong with my car, because u cant see where the Vtec point is, and also that the power is peaking too low down the revs??!!

lemme know ure thouths, cheers people! Tom!

 

well, most people are now thinking that its the actual RR place i went to, because the graphs not showing where vtec kicks in, but u can deff feel it when the cars on the road!

so hopefully theres nothing wrong with the car!!

 

Your car hasn't been tuned at all? The ECU is OEM?

Here is my graph. You can't see VTEC very well in mine, either. This is a cheap Hondata ECU.

 

no, mine has an exhaust system and a filter, but the ecu is standard!

 

You should be able to see a pronounced VTEC spike w/the OEM computer. No idea why you cannot.

What kind of dyno is this?

Here's a graph of a completely stock USDM ITR, showing the kind of VTEC spike that's typical on a stock car:



Mild upgrades on an OEM ITR can provoke a pretty wild VTEC spike, as seen in this graph of a car w/just normal bolt-ons:

 

Is it possible your dyno centre software-smoothed the graph for you?

 

Normal bolt ons, exhaust and intake? header?

 

Are you talking about my old 182 HP Dynojet? Yes, if you are.

Comptech Icebox.

OEM JDM 4-1 Header

SMSP Cat

SMSP 2.5" exhaust

That's about it.

It will appear that the Hondata and cam gears only added 10 HP with tuning, but remember that all dynos are different. The car felt VERY different after that stage, and I am sure that if it was all done on the same day on the same dyno that it would've shown quite a bit bigger difference.

 

yea, all i have on mine is a header, system exhaust and an filter.

i think that the centre must of used something that doesnt show readings very accurate, as soon as i can afford a chip, im getting it dynoed again! will let u know the outcome as the first dyno graph is abit scary!! no vtec spike at all!!
