its amazing to see the power curves. my appears to be so smooth as oppose to the others.

 

I turned my faux vents into brake air ducts. We routed high temp 3" tubing into a 3>2 reducer and then 2" piping into a 2" metal ring that now sits in the shield behind the rotor (these first two pictures were on the silverstone next to my car. I have Bilstein coils )






You can see my car on the far left here with my head right next to the hood

Someone else took after installed pics but I haven't received them yet. I'll show you guys later.

I'm sure you could reroute the piping straight into the airbox with little modification and you'd have a cold ram air intake. At high speeds, you'd have some serious power happening there.

 

Thats part of the reason I'm back on the stock ECU. Surely not as much power, but a very smooth curve

 

why cant a smooth curve be achieved with EMS? i just figured that my curve was so smooth due to the fact that i've tuned the ba-jesus out of my vafc2.

silver, where is your vtec engaugement set at? i can hardly tell by your dyno where it his the cams.

 

Thats what I was thinking. Route the airflow directly into my filter, or even maybe just stright into the intake piping. I am just trying to think of a way to make it so when it rains I don't have to worry about catching a lot of water, especially if someone is in front to me and their tires are kicking up water. It would go directly into the intake. Mabey put some kind of wire mesh screen before the filter, or make the vents detachable.

 

A smooth curve can be achieved with the EMS...see the blue dyno plot in my sig...
We tried everything we could to straighten out the ITB tune...something with the harmonics of the airflow between 5200 and 5600 rpm, we simply could not get a linear plot though there. We tried messing with AFR, timing, you name it.

Hey guys,

Got my T1R 63 mm and test pipe installed, and there is most definitely a difference. Really opened up the exhaust and the revs really climb now. Definitely more of a pull too, and dang, VTEC sounds amazing.

 

test pipe and a 60mm+ single are about the two biggest bangs for the buck!

 

My VTEC was at 5400...and the spikes around 3600 and 6600 were from harmonic resonace of the intake (apparently?). Personally I don't think the EMS has enough points to get a curve as smooth as the stock ECU, just like the idle map and start map. The EMS is no doubt a great tuning tool, but it isn't for everybody. I may just go with an AFC since it is simple and only tunes WOT thus retaining all the normal driveability of the stock ECU, and its also very cheap.

But yes my VTEC engagement was very smooth
