You really have no clue who you are talking to, do you?

Perhaps you should be a smidge more humble when trying to baffle random people with bullshit, especially when you dont have a clue what their background is.

Any more tall tales you'd like to share?

Since you asked:

Starting @ age 12: Rebuilt first motorcycle from a few boxes of parts and a bare frame.
Worked at several autoparts stores in my teens and graduated highschool with horrible grades, but still knew the value of proper grammar and punctuation when communicating with someone. Took a few years off to see what "the real world was like" and worked as clerk, carpenter, machine operator and (with a bit of school), an emergency medical technician.
All my life, I've owned an wrenched on cars - when I decided to go back to school - I worked as a mechanic (getting my ASE certs for everything except auto transmissions/transaxles) to help pay the bills.

I earned my BSE, Mechanical from UofM, Ann Arbor while working full time running dyno cells afternoons. I participated in formula SAE and was on the first hybrid-electric vehicle team where I built a 620cc V-twin OHC garden tractor engine to operate on LPG while doubling the original power output.

While in school, I also worked on several Zetec development programs for Ford (in the Walter E. Lay laboratory) and worked on a novel single-cylinder concept in the afternoons at my job.

I entered into the work force with Mitsubishi, calibrating OBD diagnostics and emissions performance. I also got into on-board refueling vapor recovery (ORVR) system design and testing there.

Next, I went to Bosch and was in charge of dyno development in their only U.S.-based calibration team. I also did calibration work on more evap systems. That project turned into the first Cadillac CTS.

I spent a long time at Ford as a calibration engineer on the Lincoln LS / Thunderbird, specializing in fuel, spark, knock and torque control. Also calibrated for emissions on the Lincoln, then was pulled over into another program (4.0L Ranger) to fix a non-compliance issue and kept a large recall from happening.
Interesting tidbit from my time at Ford - the current 5.0L that is in the Mustang was originally going to go into a "Hot Rod Lincoln", along with a T-56 under my supervision. Plans change and the program was cancelled, but I have been waiting for this engine to come out for some time.

I've been at GM for the last 5 years, working in advanced controls and integration. Think of it as a "Technology Skunkworks": We take promising new hardware, install it into a representative vehicle - and then conduct a complete development project to see if the tech can meet emissions/fuel economy and performance requirements. If it does, we hand off a validated set of controls and calibrations to production and help guide the tech into the customer's hands. You may be aware of GM's leadership in DI technology - that came from us. Hear about HCCI in the news? Us again. My last project I finished will be going into production in 2014 and features certain different valve actuation to achieve a fuel economy benefit.

Along with working for 4 different manufacturers and with 1 more, I can answer your question - yes, I have hooked up a computer to a vehicle and worked with calibration. In fact, I've worked with:
ETAS INCA, V100
Ford RCON & Calvin
Accurate technologies / ATI
Mitsubishi's proprietary system
Chrysler's Interrogator Box
...and...
in the early nineties, we used to record data on thermal strip chart recorders - an absolute pain in the ass for any weather that wasn't a pleasant spring day. Anyway, I went out and canvassed several different medical research companies and adapted a 32-channel data acquisition interface to run through the serial port on a laptop. I wrote a program to define sample rates and had it write files I could import into excel to crunch data.

I absolutely hated using a scale and calculator to read signals on paper. Oops - almost forgot, I've used a CARDAQ and more programs than I care to remember. I should also mention that I write and/or engine control software to adapt new hardware into the vehicle. I'm just finishing up a project for the 2015 duramax that is an exhaust aftertreatment control.


Last, but certainly not least, I hold 3 patents for controls, currently am awaiting decision on 14 that have been filed and have (IIRC) 5 inventions waiting to be filed.



So, now that I have given you my background - that started 30 years ago - let me also add that I mean this in no way to be a contest or pissing match between you and I. If you go through your posts and read what you initially said, it does not match what you say now. I believe it is because you spent some time on wikipedia - and it looks like you've learned some things - and that is commendable. Never stop learning or asking questions - but you may want to take a bit more time when recommending things.

BTW you still haven't answered this:

LOL, Scooter, we were just talking about how fun strip charts were. Remember with your files from a test used to have 30 big rolls of paper? THe fun of watching the back seat filling with paper as their cranked out.

I remember back in the 90s when I was in powertrain doing engine control stuff, we used to be out at milford a lot. THe old ECU simulator computers used to be big enough that they made desks out of them. I went from fuel systems/evap emissions @ walbro to engine controls at Siemens to core electronics development @ chrysler back then.

We still do a ton of powertrain at Conti, but I like dashboards, we have pretty lights..

We still use those simulators in the loop with new components to bench test software before seeing what it will do in the vehicle.

My favorite was the temperature dependency of the yokogowa 8-channel units we used. Back before any heater we considered safe to run in the car overnight was available, we would wrap our instrumentation in electric blankets for the -30 development work. Once we got the DA system initialized and were ready to do a start, the blankets came of the recorders and we would cover up with them to warm up during the cold start. Also, you learn pretty quick not to leave your data in your car on a hot test trip!

I think you were doing your walbro gig around the same time I worked with Chrysler / Mitsubishi. I was always frustrated that the I-box could have multiple pages of data with 16 channels each, but there was only - what? - 10 bnc outputs on the side?

no i dont know him and in order to get an actual degree yes i had to take speech, math, and a couple other basic college classes. i know i probably had grammatical errors in there but i didnt feel like taking the time to back and proof read it.

What about all of the other items you haven't responded to? The grammar was just the surface and not really worth discussion. The other topics are still untouched.

That's what happens when you spew your utter bullshit about things you know nothing about.

hahahaha......... this thread is pretty funny. Let me summarize.

- An innocent guy asks a simple question about how to improve performance on his 5.3.
- A wanna be expert chimes in with his basic knowledge.
- Guys who are expert in the field challenge said wanna be with deeper technical questions.
- Said wanna be gets defensive, spouts off his basic education (which by the way I commend him for going to school and bettering himself) and throws down the gauntlet with a "I bet my education is better than yours - so there" attitude.
- Said wanna be expert failed to realize that this is the motor city where most of this stuff actually gets developed and he just might run across someone who actually works in the development field.
- Low and behold, the guys he is challenging actually turn out to be experts with more years in the field than said wanna be has been walking.
- When all this comes to light, said wanna be now accuses others of cock fighting.
- And finally, said wanna be has still failed to answer the questions that were asked of him early on.

Scooter FTW. LOL

Oh, and Mprmno8, just to give you a heads up, some of the regulars on this site have some very high credentials. Here's a few (and I'm not any of them)
- Scooter, well he already told you.
- One guy has 30+ years in GM's advanced engine research
- One guy is an instrument/wiring guru
- One guy is a vehicle electronics expert at the proving grounds. (actually I think there are 2)
- One guy has worked at GM's advanced engine research, advanced transmissions research and GM's corporate racing development
- One guy has been a Chrysler race tech working on the corporate race team at places such as the Baja 1000.
- One guy is an advanced project launch engineer for Ford.
- Several guys here have raced at the high end corporate sponsorship level.

Those are just the ones that come to mind quickly. I tell you this so you can appreciate that there is a lot of GOOD information available here but also that anyone spewing half truths will get called out.

Let's just drop it, eh? MPRMN08 isn't stupid, just stubborn - and me, well, I'm tired of pooping in Hawaiian's thread.

Thanks for the kind words, old man.

I pointed out your obvious stupidity, and hopefully given you something to ponder about before you decide to sit down in front of a keyboard again.

So if you have a custom tune on a 5.3-(2003), CAI ,and Exhaust-what is the next power adder? I have HEARD a cam is a good addition, but what will the cost be more around $500 or $2000 for the complete "package"?

Since you have most of the other supporting mods, a cam would get you the next largest gain for the investment. You'd be looking at 400-500 for the cam, 120 for pushrods, 200 or so for springs and then 150-500 for a retune plus any labor charges.

$1000 to 1500 would be realistic.

Not when you're already down there, "tooting" it. For the record, I was asked to provide that info.
