Congrats dude, nice job.
I think you need to finish your degree and send your cv to gm powertrain

Marcin,

You are nuts!

Now that the complicated math is figured out, myself and my neighbor have to figure out something far more complicated. How to explain to his wife that the c6zo6 really needs twin turbos.

Marcin,
Here's hoping for the day when your model is translated into a procedure for use with popular tuning tools that is simpler and more accurate than the current AutoVE.

there's not enough math in the world to justify that one ****, i cant even justify getting a new car myself... well, i did just see a tune for the new 2008 LS3 vette and there's an IFR table for pressures from 0 to 600+kPa! this means you can map out your fuel pressure and describe it no matter how much boost you got, and what kind of crazy **** you do with regulators. combine this with GMVE being generated dynamically and not locked to 0-4095 like on the E40 and you have NO LIMIT ON AIR OR FUEL. no more hacking, no more lying, no more 'scaling'. the tuning nirvana is here, and hopefully with this new math we'll be slightly better prepared for it.

You need to use wife tactics on your wife... "Honey, I justed saved you a whole bunch of money by installing TT's on the ZO6..."

Marcin, are you looking for a volunteer to try your 'math' on a C5 LS1?

sure.

i'm putting together a short guide on how to set up your scanning so people can just gather logs and send me stuff. i'll post it here once i'm done, but i still gotta go deal with thesis advisor and such

The one chart I saw earlier in this thread, looked like it was a
gut-sensible one (bias=1.0 at zero flow and 0.0 at higher, like
you would expect from just thinking about how much time over
the stove). The question is really in the middle ground, how
soon & fast do you transition from extra crispy to sunny side up
as airflow increases.

I'm a bottom line kind of guy and I would very much like to see
the final result, table and pictures, for a normal plastic intake,
241/243/317 heads, NA, IAT in the pipe kind of setup.

Looks like Ross and Paul have simplified this in their program. EFILive is amazing.

Actually, after some thought.....the amazing is that Marcin was able to solve this without access to the pcm code. AMAZING!! - hat's off to you Marcin.

after looking at it at first i was like 'oh ****, there goes a lot of work.' but after a closer look, they're after a different thing than i am. they wanted to bring a familiar view to the users used to the VE/GMVE tables. I am after a much bigger goal, a whole new universal way of tuning, and approaching it with the new response surfaces model is just one of the prereq's. so not all work is lost. i still gotta figure out injector characteristics, because all the short pulse fueling is off and without that we won't really know the airmass. to further compound the issues, short pulse fueling is in effect at the same situations when BIAS differs the most (low airflow), so without knowing the injector stuff perfectly, we will end up using BIAS to make up for injector calibration's deficiencies, and that's just bad science.

kudos to EFILive crew, it's really neat to see some inventive thinking and providing real support to the users, not just releasing support for more platforms to build user base.

have you guys ever heard of AIMMS? i'm using it right now in my senior math course and we're using it on a model to minimize cost. not very familiar with it but it's supposed to be easier to use than matlab as far as linear programming and optimization goes. you can also import data from excel and apply it to your model.

just curious

can anyone share with me some of Marcins docs and spreadsheets that were available on his blog? everything is gone on the site

WOW! I never expected this thread to last 8 years. And in more depressing news, we never TTed the C6Z06. It always seems to take second place to modding the 1970 vette.
