I'm always up for a comedy movie

Makes sense...what can you rev those puppies out to (useable power wise)?

That puppy moves out. What kind of HP is he producing on that sample? When does the 6x turbos spool on the 2.0/2.2 -- 4000ish?

Cleveland people can be coated in snake oil sometimes

Save your life possibly?

Is it a black vert? If so -- he might be holding some mods back...

Well, 5,000$ saved my eldest brother's life, stopping a 7.62 round from about 20-30 meters. Guess that means Ranger's are what they say: practically bullet proof...haaaaa I would rock a vest delivering pizzas...

Not sure where the best place to get one is, but military folks seem to like "dragon skin", from Pinnacle Armor.

What are you doing out here on the street corner? Selling Oranges? But I ran out..

Whats the curb weight of the S2K?

Nice ride, keep us up-to-date on the progress. Welcome

YO YO CHECK THIS OUT GOT MY REPORT CARD ALL F'S GAVE IT BACK TO THE TEACHER AND SAID YO THROW SOME D'S ON IT!!!!

I could see that if you treated n variables as constants. Eg: What does the result look like when our intake cam is locked at 10* and our exhaust cam is locked at 30*. The plan is to start off with the basic cylinder air-mass equation. A 3D quadratic is very graspable to those who haven't had to endure the painstaking 400 level engineering math courses. The ultimate connection I feel is the graph that illustrates what a system response curve is.

What we like to call: bad science. There was very little data showing 100kPa at 500-1000RPM. Bad/No Samples leads to bad science. Brandon - I could easily see the Germans using this in the Motronic platforms. Until Conforti comes out with his ODBII editor/data logger there are very few and far between tools to reverse engineer any model based DME out there. The funny thing is - of all of the car companies - Honda is still trying to do it the old fashion ways. The K20 controller has 6 "VE" tables to cover the dynamic states of VTECH and interpolation between cam phases (40 some degrees?). As far as training: you'll recognize a name or two. It's going to become a group effort as there is a vast amount of ground to cover because each platform uses a different temperature estimator, making things even more complicated. Once we have a wider sample of cars, data, and proven results; we'll make a large push to produce documentation and possibly a training class. Phil - You are absolutely correct. You cannot "graph" a 5D quadratic. There won't be a visual aid at this point, but the numbers still work out. At this point, most of the tuning will become empirical. We may hope to expand that, but at the current time we're working in 3D to help bridge the gap and soften the learning curve.

Harold - Tinman can give you the details. He's very experienced and knows way to much about ramp rates and the affects of different profiles. No matter who it is, provide every ounce of data to them and you'll be a hair closer to getting the powerband you want.

Welcome to the new world.

The reason I ask: The systems GM is producing are still MAF based but MAP and BARO are making up for a larger amount of calculations. There are no "look ups" involved with the E38/E67 platform - everything is calulated real time. The problem I see is the math involved, mainly linear algebra. There's no good way to simplify the applied/engineering math involved. The course would be mostly a math class. Not sure how well that sits with professionals and enthusiasits. Here's s a sample from MATLAB (who'd ever thought you'd actually use this program outside of college) of the response curve that's calculated by the parameters that can be configured in the PCM. The data used is 43,000 samples from an 08 vette. http://img219.imageshack.us/img219/9494/deantrial1ra8.png X axis is your RPM, Y axis is your "GMVE", or VE% and Z is MAP kPa. You can see the 30 "zones" (each zone looks like a patch on a quilt) without to much trouble. The nice thing about the function thats used to calculate this data - you can use it ANYTHING with RPM and MAP values. There arer no limits, and no lack of resolution. It is a truely portable solution, whether you have 3 dimensions or 13, the math is the same. <3 GM Nate

Hi Folks, This mainly applies to the GM crowd but other input is welcome. Do the masses see a need for documentation and potentially an instructional course on GM's new model based VCMs found on most 05+ vehicles? Thanks Nate

CCNP (passed the written for IE but am no where near the hands on), MCSE & MCAD, started with A+ and Net+ in high school. Have done a lot of IT/Business work where exposure and accountability where high. Currently working on the security side - CISSP. If I ever return to IT, I'll be pursing security/cryptography

Wow.
