why dont u just measure it (frontal area)?

as for CoD, i'd estimate anywhere from 0.30 - 0.33..
the old VIII/IX was something like 0.30...

well i measured it and its 20.37ft2 can anyone else confirm this?

Bump on the frontal area and CoD!

I'm also using DLL

Pretty cool program I say ..

frontal area can leave it at around 22sqft .. CD is a tie between 0.36 and 0.38 (IX figure) .. I say 0.38 is a pretty close approximation ..

Its very close to the dyno I tried earlier on

BTW it was raining when I tested .. so the SAE correction would probably push it up even higher ..

I've been playing with the evoscan internal dyno (not so great right now)

and this: Virtual Dyno Room-Dyno Simulator

That is actually pretty damn nice

pretty cool, let's tune it and see the difference shall we?

what definition file are you using for dataloglab, I'd like to run a fuel/timing only tuned X through to see how it's looking so far above it's stock logs.

iam using for coefficient drag 0.35 and for frontal area 20.37ft2 and for curb weight iam using 3,594lbs
and on 3er gear iam using 1.754 with a relative lost of 7% and graph smoothing factor of 5.

mellon for ecuflash where do i upgrade the one i had for the evo8 so that we can tune this mr? also i still dont have a wideband nor a boost controler does this matter on the tune?
thanks

jrsimon27 · Jul 15, 2009, 02:45 PM

update this on 93oct feels better.

13whp more and 4lb of ft torque more compared to 91oct.

I keep finding a drag of .34 and frontal of 22.9...where did you get your info? mine may be incorrect, it's hard to find two sites with the same data.

3rd gear is 1.440 I confirmed that for the 5-speed on multiple sites including mitsubishi's site

I'm using 3550 for weight which is what the owners manual said for my customers car but it hasn't been scaled. We were at half a tank of gas.

I have links to everything you need on the website ecuflash 1.42, you'll need a good MBC like the Forge UNOS.

DLL results before and after a tune on his stock x with just fuel/timing adjusted, no boost changes yet. This is on 93 octane

the coeffiecent drag got it from gunzo so i will lower it to .34 and the front i measured it but i subtracted the clearence from the ground so maybe thats why i got my measurment wrong.
3erd gear is different in my car cause its the mr model not the gsr and the weight of my car i found it on a brochure they gave me for the car.
ill check in your site and thanks mellon
