I have read a number of threads in here referring to the person that programs their aftermarket chips as a "master tuner". I have never tuned one of these chips but what is so hard about it? What do these guys do that could not be done by a computer program? I fail to see what makes these guys so great at tuning a car. Do they watch A/F ratios all day?

 

not even going to bother to go in depth about this question..

 

Its not just A/F ratio, there is much more to that such as cam angle, timing etc. Most of us including me don't know what those exactly do and thats when tuners can do their magic. If it was just A/F ratio i don't think tuners would have a job to do.

 

If you read my review of Church Automotive Testing and Osiris tune you’ll get my perspective.

Simply put a good tuner knows the car, and has enough experience tuning to get the most out of it… I know I couldn’t do it, not right away… maybe after a BUNCH of tinkering, but I’d rather have it done right, relatively quickly

 

first of all, these arent just "chips" they are playing with. the "chips" you talk about for other cars change maybe a couple properties of your ecu that give you more power at the expense of other things like mpg, engine life, etc.

what a good tuner does is run your car on the dyno and in real time, adjusts different aspects of your engine to give you the most power/safest tune or somewhere in between. with how simply you throw out the term "tuning", you appear not to know how much goes into it. now these guys arent magicians, but just like any other profession, they are good at what they do.

 

^^^good points... like a "Master Chef", just because you can make a grilled cheese sandwich, or even chicken cordon blue, it doesn't mean you are a master chef.

 

Every tuner out there has gone to some type of class to learn about a certain EMS or basic EFI classes . Having engine building background also helps . After that , its like every thing in life . The more you do it , the more you know and the easier it is to do it .

 

So if I had a dyno at my disposal I could basically do the same thing but I would not have the experience? How many different factors can be adjusted?

 

have you read any of the threads?... read up on tunes here and on my350Z... when you have questions worth asking then try again...

 

they also know where to start and what limits to not go past. Someone with no experience can easily blow up an engine by adjusting the parameters incorrectly

 

I truly appreciate your help. Your write up in the other thread is very good I just wish I could say the same about your attitude.

 

for every good advice/info people gave you, you came back with a question that prompted whether you had read anything on the subject.

As for my attitude, maybe I should have not bothered to address you at all. My fault I guess.

 

unless you can program a car ecu, i doubt you will have much luck tuning one. your lack of knowledgeable questions will prompt similar responses. yes these forums can be rough but remember these questions have all been asked before.

 

With that being said...do you guys think a master Honda tuner will be able to properly tune the VQ? This goes out to some of the big shop tuners on the forum.

 

^^ interested in that question in general as well. Subaru's use UTEC's as well. so if a tuner is great at tuning UTEC's on the G/Z, does that mean they could tune out a STI or Forester XT easily? Or are they still missing the findamental knowledge of engine params for those specific cars?
