Case Study: Road "Tuning" vs Dyno Tuning (Merged)

Anyone who has any experince in this business will realize that tuning method and dyno operation is critical to obtain a accurate REAL WORLD llaoding on the vehicle when tuning on a dyno
The DYNO is a machine which attempts to REPLICATE the conditions of the real street where the vehicle is used

What in the world are you talking about Al?
This post above all others shows me that you know nothing about proper tuning and you are ripping these poor people off.
I have sat back and watched this thread progress but now I am mad. You are ripping these people off man.
Al I have a moon dyno 30 miles from my home, it will put any of these EVO's in any portion of the maps you could EVER EVER attain on the street and then some that you will NEVER achieve on the street. Last week I had a car on the moon dyno and held it in the portion of the map (cell) that corresponded to 1900 rpm and 3 lbs of boost. Al I held that car steady state for 35 seconds and tuned that load cell. You will NEVER EVER be able to do that cell on the street EVER. And if you come back and tell me you can do this type of tuning on the street I will call you a LIAR.
The aforementioned MOON DYNO along with several other dynos out there can put a car in ANY Cell that you can achieve on the street. What part do you not understand. Wind and hill grade do not mean a thing about real world testing when the ecu is placed in a certain section of the map it does not know if the load is from wind resistance or an eddy-current retarder. Since the engine is what you are actually tuning not the vehicles body.
Fortunately it looks like quite a few people on this forum are somewhat versed in basic proper tuning concepts. But to those who are not it is NOT FAIR for you to come on here quoting this blasphemy and taking these peoples money and them not knowing any better.
Speaking from a tuners prospective and from someone who has morals. You sir are a crock of **** and these people do not deserve to be lied to anymore. Sir you need to be exposed for who you are and stop spreading all this false information about a subject you obviously know little about doing the proper way. I can not believe you have been making money off these poor people.
edit: oh yeah quit dodging Shiv's Question and answer it please.

I certainly disagree with your position - but dont feel I have to lower my self to your level to call you a "craok of * * * * " to make my point
Chasis dynos are goo dfor making $ for dyno shops and those who make the dynos
For tuning they are a fair tool and a resonably close approximation to what kind of loading the cars sees on the actual road.
I tune on both dynos and the street. I am prob 60% dyno 40% street - but I still prefer the road.
In any event - with individuals like this guy making personal insults and calling me a liar it makes if very hard to continue a meaningful dialouge on this subject.
I may have to open this topic for debate in a more controlled venue.
I'll sleep on it.

The pot calling the kettle black
The only thing unproffesional and undesireable is how you are treating customers and the whole basis of your business. I am attempting to protect these people from you Al. And you still must of not read about the type of load does not matter to the ECU as long as it is in those cells so they can be adjusted properly. Oh yes you are a liar.

Frankly I find your assertions rude and unprofessional, there is a civl an a non civil was to agree and disagree calling some one a "crock of * * * * " is not my idea of proper way to conduct your self.

And what about that challenge that you and DB issued to me? Did you retract it??

Just an interesting tidbit of info.
In the last 4 days, this thread has generated 22 reported posts for its readers. Most of them from a vendor who has his own forum

Shiv wants to partake in the challenge you layed upon him, are you retracting it now that the fish has taken the bite?

I'm not sure it's a good analogy. A tune controls the way thousands of dollars worth of equipment operates. I would hope there is not as much room for improvement as you're claiming. Especially since there's just not that much room for innovation in reflashing when you're basically just hacking map values - you're either doing it optimally and safely for a certain target application or you're ... "improving" every day.
Al, why is it every time someone makes a valid claim against road tuning all you can do is say how unprofessional and rude they are? You never fully answer the questions that people pose to you. You either dont answer it at all or you beat around the bush and seem like you answered it. Why not just be straight forward and frank about the question?
I guess so you can delete the posts that do not work in your favor?
