Hi all

yes, i switched to ectune finally, and while [email protected] today i began thinking
of a program that translates my ectune logs into something dyno-like. if not
for comparing absolute numbers then this would be helpful to just compare
different runs of your vehicle with different settings. then i realized - its already here!

BradBarnhill.com

i quickly noticed that CSV exported ectune logs can not be read with it,
so i just wrote a quick script that converts ectune logs to something
virtual dyno can read.

Download it here

just place your csv file(s) in the "original" folder, run convert.bat - they get
moved into the "converted" folder - and open them there.

being quick and at work right now i could only find an ectune log without
afr's and boost logged. if anybody could quickly test this with a
complete log post a screenie here!

the software tries to seperate WOT sections and it seems to be fairly good
with this. the screenshot log had 2 wot sections and a short wot-blib
which seems to be the one strange hp line that goes backwards
- not sure with this one ;)

if you want it super clean i guess you can always try to only do wot or 0% tps
or split your logs in multiple files...

to do: import honda tranny/weight specs. if anybody updates those with his
car just send me the XML config files and i will compile them together.

teaser pic:


this is 2 times the same ectune log just with different car settings - but
i guess it shows pretty nice what this prog does ;)

€dit: i forgot something important ;)
you need to customize your settings like this:


or get my columnames.xml file and place it in your virtual dyno folder:

of course. It is just some simple unix sed magic.

For the EVO people it looks like it can be pretty accurate. Several
reports from 0.5-3 kw difference to the dyno, so i guess there is
already some math in there, although i do not see a way to enter the
cw value of your car ;)

€dit: indeed there is something: you can set the Frontal Area and Drag Coefficient
(besides other things)

how to get your frontal area


i guess i will try this with my hatch :D

€dit 2:
found it ;)


guys, we absolutely NEED to get this thing loaded with some honda specs and see what comes out!
(unfortunately no WOT pulls for me atm, my motor is waiting to get pulled and resurfaced -.-)

there is a list of each civics drag coefficient and frontal area available on the internet. not too sure where, maybe i bookmarked it...

anyways ill see what i can do after work.

i would like to do a fresh pull for you to see, since i made some changes on the dyno. picked up 2whp by removing some timing.

anything that outputs a csv file is super easy to adopt.for anything that outputs other formats you could create your own converter what is more or less complicated-depends if the format is known or if you have to reverse engineer it

if you lower your car it'll change the drag coefficient. think about it, instead of more air under the car where it'll travel smoothish, your now forcing more air above the car where it hits the windshield and gets forced around it. i would imagine it would change a great deal

those numbers are for stock height and shape civics. i don't know about you guys but i modded my suspensions long before my engine.

Here is an output graph on a B16 Turbo EJ1 with B16 Trans I did last week. Just got around to setting up Virtual Dyno for my Crome CSV files.



This is close to what it should make. We'll be getting it on the Dyno pretty soon sometime. 304hp @ 7093 and 237lbft @ 6730 all on only 8 PSI, forged bottom end, OEM top end, .48 a/r exhaust, .63 a/r compressor ebay "50 trim".

why did you turn smoothing to 20, what did the graph look like
with the default setting?
