pretty impressive gains from just an intake. I wonder where more power is still hiding in that beast.

 

I cant wait to see it with a proper turbo back exhaust!

I am all excited about these tests!

 

So basically the 29whp gain is basically bringing the car to a tuned status.

 

I knew people would misread this info.

Vivid is NOT saying that intake will gain the car 29whp. They are saying that the car was detuned already with rich AFRs and the intake just brought the AFRs back up to resonable levels which yielded a 29whp increase. You could just as well lean the car out and keep the stock intake on the car and get the same gains. The REAL test for the intake would be to see what the gains are when the car is already at reasonable AFRs.

 

Wow I can't believe it made nearly 30whp with just an intake kit and suction pipe. I've never seen any EVO make such gains with an intake kit and suction pipe. Usually intakes are pretty much worthless and just a drop in filter will do. Wow and this is without any form of tuning. Simply mind boggling if this car puts down 40whp or more with only an intake and exhaust. Anyhow thanks for the early testing, it will be interesting to see if other shops and owners get similiar gains.

 

True. Or you could just buy an intake and get 20whp+ You make no sense, you say the intake didn't yield the 29whp gain, but at the same time you say the intake brought the AFRs back up to reasonable levels. So it was the intake that helped to do this, so it was the intake that helped to achieve the gains. I mean I get what you are saying, but yes the intake in this case did seem to play a role in gaining power, and while you are saying there are other ways to gain power, that still doesn't take away from the fact that during this testing, this EVO X gained 29whp with the addition of an intake kit.

 

And this will cut down on the gas mileage too. Added bonus!

 

Seriously.

It pains me to see someone have to explain such a basic, common sense theory in great detail...it's almost like people are treating this car as if it's some revolutionary phenomenon.

I'm surprised that Vivid, and other reputable shops, even bother putting up with it....

 

I don't doubt the richness of the car one bit. My only concern is that the ECU is doing something funny. The intake temps you are seeing in Arizona may be a bit different then what Chicago and New York see. If a basic modification like an intake made that much of an A/F change at WOT.... (imagine the part cruise and STFT's)then it makes me believe that you will run into difficulty (ecu learning) with other modifications that increase the ability of the engine to process more air. Listen, for everyones sake, I really hope that the car is extremely flexible with its learning strategies. If not then simple everyday drivability could become a problem without comprehensive closed loop tuning.

 

Absolutely NOT. A/F is only 10% of the equation in some cases. How you got there, directly or indirectly effects the state of the tune.

 

Actually no, A/F is a very important aspect of not only gaining more power, but increasing gas mileage, and better drivability. I know a little about tuning, but not a lot. Mitch could you please chime in a little bit here. I highly doubt mitch would have done something to the tune, that wouldnt be realiable and benificial.

 

I have nothing to tune this car. I can't do anything with it. This is not smoke and mirrors just s simple test that gained a ton of power.

Nick I do see what you are saying about the fueling. I think it will be very interesting to see what kind of adaptility this car has. What if there is no open loop really at all rather a closed loop lambda table like Porsche?

We will just have to see. But for now this is just a test of an intake and the data I have is on that dyno sheet. I am just itching to know the overall funtions of this ECU but that will take some time I am sure.

Actually Yes, IN MOST cases, just changing a mechanical part of the induction system only "TUNES" the car around 10% in regard to A/F. My point was to the original poster stating that the car is in a tuned state.
I am also aware and can confirm that Mitch has no way of tuning it. That was not the point i was trying to convey.

 

If we can get the boys to dissassmble the rom...it should make things very clear.
Well it would make it very simple to find out...Does the car have a wideband style converter or sensor on the car?

 

Where are you guys putting the WBO2 senser , did you weld a bung in the DP ?
