Hey Chuck, thank you, I never have time to get on the phone and the computer is definitely faster. I'll be the first to say that I'm always skeptical with things I do not fully understand. The cow booster is one of those things that even though I've read post of yours and very few other people who claim to be happy with it and what I've gathered is that your pretty vague with how it works and the people that have it are even more vague. With that said, don't take this personal but I know a salesman pitch when I hear one and I will call BS even if it makes me look stupid mostly because I could care less about what anyone thinks of me. Anyway, I dont consider myself a tuner persay but I know my way within reason around HP Tuners though there are plenty of people on here who are leagues above me in that area. Further more I know you said that, there is no way to do what you do as it pertains to the "Cow Booster" with HP Tuners but I should definitely be able to compare my current tune utilizing HP Tuners or EFI Live to whatever you do with your hand held programmer to my current tune to see changes. I want to send my PCM to you but I want to fully understand the cow booster before I do so.

Does it change the sensitivity of the TPS to the electronic throttle body? If so, How does it do it?

Here's what I think it does based on what I read, Please let me know whats right or wrong or close or whatever.

"My understanding of the "Cow Booster". Ok I'm going to use whole numbers and explain this in a manner that everyone can comprehend what I'm saying. Ok for The purpose of simple math, in this explanation, Lets say your throttle body has a 100mm opening when the throttle position sensor is at 100%. And your throttle blade is Wide open.

Now for my example. Lets say that your at 25% on the throttle position sensor and throttle blade is at 25% of its wide open position. This would mean that your throttle body opening is at 25MM . Is everyone with me so far? Ok good.

Now let's say you go from 25% to 100% on the TPS, between the time the VCM registers that you have commanded 100% throttle (based on you smashing the accelerator to the floor) and the time It's going to take the throttle blade X amount of time to travel and go from 25mm to 100mm position. LETS CALL THIS THROTTLE BLADE OPENING TIME (I BELIEVE THAT THIS IS WHAT CHUCK ALLEGIDLY PLAYS WITH)

Now lets say this is a vehicle without the "Cow Booster" and you move the throttle position sensor from 25% to 100% as fast as your foot can press the pedal and from the moment the throttle position sensor gives a output of 100% it takes 15 seconds for the throttle blade to go from 25mm position to wide open or the 100mm position.

This is where the "Cow booster" comes in. The "Cow Booster" will shrink that time thus giving you the better throttle response and the feeling of a faster car. It does this by moving the throttle blade faster. It's like lowering your throttle blades ET's. LOL!

Lets say that with the cow booster at the moment 100% throttle position is sensed it only takes 10 seconds to move the throttle blade from 25mm to 100mm from the moment the throttle position sensor gives an output of 100%. this will give you the feeling of a faster car. It actually isn't a feeling of a faster car its reality. The car is faster though it don't make any more power, it will make the power that its capable of producing faster then normal by allowing the throttle blade to open faster.


of course I could be way off... tell me what's up Chuck!!

I was thinking the cow booster was a hand held tuner you plug it into your car and drive it then chuck can give you a tune from his location no matter where you live. Its like hes logging your cars tune remote?

SBCGENII

Tuner loads a tune into the autocal then the customer flashes it themselves. Or you can also have the autocal log the car w/wo wideband and send the autocal back to tuner for corrections.

a/c man

So I sould get one and install it then send it back and they can tune my 900rwhp car better

SBCGENII

Yes they can make your 650rwhp car 900rwhp.

0Chuck CoW

That is our AutoCal remote tuner device. It's an amazing tool that lets me do just about anything I want to the

PCM remotely.

Thank you.
Chuck CoW

No, the CoW BOOSTER! will make any vette very exciting to drive everywhere BELOW about 3/4 throttle, but since your blade is about equal to the pedal position near WOT

there will be no difference above that point.

I'm not vague about what I do, it's just that I've tried multiple times to explain the details and give examples,

but some people never get it because they do not understand how the throttle system works.

I'll try again.... In the graphs I post, take those to be the "throttle limiter tables" where you press this much

and you only get THAT much.

I have changed the limiter tables (which nobody can see with their tuning software) so, when I modify

the tables the throttle is "allowed to be more open than it was before".

People talk about the "illusion", "feeling", or "sensation" of having more power like it's not something real.

It is REAL....It is POWER all "under the curve" It IS possible to have more power or add power that was not previously

available without increasing your WOT PEAK number.

For those that don't get it...or WON'T get it.... I can't help you more than that.

For those that understand that power is "missing" under the curve or the throttle does not respond quick enough,

then you know what I'm doing.

Insofar as the "speed of throttle opening"... I don't change that. The blade is plenty fast enough and well faster than YOU.

As a human you are not capable of replicating the CoW BOOSTER! with your foot and all that's happening is the blade is

reaching the "desired blade position" (which has been increased) in what appears to you to be LESS TIME

Again, tough to digest, the blade moves soooo fast, that before your have time to think about where it is....It's already there

making you think the blade moves quicker than it does.

Yes, throttle does "feel" much quicker than before, but the speed of the blade does not change if you follow what I'm saying.

Again, the speed of the blade does not change (it's always the same) but it covers more ground in WHAT APPEARS TO YOU

to be the same amount of time....Which it is not.

Regardless of how well some understand it or how I explain it It add loads of FUN to ANY LSX ETC vehicle even thought

it does not make for a WOT peak number improvement.

Are we getting closer?

Does the stock PCM limit the throttle opening at lower RPMs, for instance only having the throttle plate at 70° instead of a full 90° at 2000 RPM in an attempt to prevent abuse or starving the engine, etc? Or I can imagine that at low rpms that the throttle reaches max airflow quickly, perhaps 40% TPS yields same airflow as 100% TPS, so the PCM scales it down to give more precice control of power with the pedal. I can certainly see this decreasing power on high HP setups.

Or does the modification focus on opening throttle more at lower TPS settings for increased power in non WOT scenarios?

I could also imagine that the true TPS vs throttle plate angle would get skewed with higher HP engines, and especially F/I. Like maybe what used to be 60% TPS is now only 52% TPS after putting 10psi of boost on an engine.

Now I'm curious to try playing with this!

0Chuck CoW

Hey there. I've done my best to explain this so far and I've tried a few different angles...

But, it appears that not everyone get's it yet.

Everyone please remember that C5s and C6s share some similar principals when it comes to the Electronic

Throttle or "ETC" controls, CoW BOOSTER! is a C6 product for any of the "CAN BUS" controllers like E40, E38, & E67.

For example Corvette from 2005-2013 gets CoW BOOSTED! and while I do something very similar in the C5s....

We don't call it the same thing because it's not nearly as complicated to do.

It seems that people are getting confused between my C6 CoW BOOSTER! and the C5s and the biggest

mistake they make is looking at C5 throttle controls things they do the same thing in C6.

It's funny, but sad at the same time watching people have these "AH HA! GOTCHA!" moments where they think

they have discovered or uncovered some secret table that I use for CoW BOOSTER!

I'm a pretty direct and to the point guy... If you forget what you THINK you know and read my words

you'll get it.... I've told the story a few different ways to make it easy for people to digest.... Some get it...Some don't.

Having had a talk with a former GM calibrator this past week on the subject, I think I"m going to make a new

CoW BOOSTER! thread to try to help make sense of it for some people.

I'd like to take the approach that It's MINE, IT WORKS, and IT'S AWESOME, and can help SAVEGAS! - REGARDLESS

of how it works, but people seem to NEED to know more, so I'm going to try to make a thread this week

that explains it "differently" than before....

Wish me luck.
Chuck CoW

a/c man

Good luck Chuck!!

0Chuck CoW

YES, the stock pcm limits throttle blade opening below about 80% or so.

It is not complicated like you suspect. It's quite simply limited so that the blade is never where you want (or think)

it is below that 80% (approx) amount.

Significant gains in low and mid range performance are achieved.

It's ll relative to pedal position and nothing is gained at WOT but low and mid are tremendous and lots of fun!

Call anytime.

Wow...this CoW Booster sounds like the "cat's meow" for my application...impressive data!

Knome

BTW...if I am reading this right, are you writing about low & mid range pedal position? I am confused?

0Chuck CoW

Yes, everything we post about CoW BOOSTER! is in RELATION TO PEDAL POSITION.

At part throttle (low and mid) the stock pcm limits the amount of throttle opening RELATIVE TO PEDAL.

In other words, you press 50% down on the pedal and the stock pcm gives you 5 or 6% BLADE OPENING.

Big BUMMER!

With CoW BOOSTER! most setups will get you about 35% BLADE when you press 50% pedal.

Why not 50% for 50% pedal???

#1 It would be far too aggressive to give you that much.

#2 One of the best parts about the CoW BOOSTER! is that it changes the resolution of the pedal so that

it's much more linear than factory and actually gives you more control.

There is a competitor's product that plugs into the pedal and attempts to do the same thing we do, but

it significantly shortens the resolution and with their product the BLADE IS 100% OPEN from about 3/4 PEDAL TO

100% PEDAL. The effective pedal/throttle travel is shortened nearly 25% leaving the throttle 100% open for a full 25%

of pedal travel. In other words, when your foot is at 3/4 throttle your BLADE is 100% open for 25% of it's travel.

Sounds scary right??? I would prefer that the throttle was 100% open ONLY WHEN I WANT IT TO BE.
