I got the number for a guy who is selling a diablo tuner locally for cheap. I gave him a call and we talked a bit about it. I mentioned that I was running a vortech, he said that it probably was already tuned to run nicely with my car and that his diablo probably really wouldn't do to much more for my car. What do you guys think? I don't have a hand held tuner so that's why I wanted to buy his should I or not?

 

how do you have a vortech and not a handheld? did you get it dyno tuned or something else?

 

Yeah it was dyno tuned a few years ago and nothing since then. I am just wondering if I should buy a used hand held tuner or not?

 

[/align]Not to be unkind, however the fact that you are asking the question means no...[/align]

 

Thanks for the input.. I am trying to learn though!

 

a dyno tune is a more advanced tuning, where they actually make a custome tune specifically for your car, while a tune in a box is just a generic tune

 

[/align][/align]Excellent, too many are looking for easy answers...[/align][/align]Ask questions, and read, Read, READ!!![/align][/align]If you are willing to learn and experiment (carefully)the Sniper Special Forces package would be a good place to start, it will support your centrifugal blower with it's dialog/response based initial configuration, and will let you tweak things to your liking beyond that.[/align][/align]Contrary to what you mayespouse there really isn't any wizardry, magic, or even rocket science involved in tuning; it's just a question of learning how it all works, and having and understanding a tool that let's you make the necessary changes. In fact, like most everything else it get boring after a while*.[/align][/align]-[/align]* -In fact, I bet that even Hugh Hefner gets up some mornings and says "if I have to look at another set of **** I'm gonna' puke"; hard to believe but I bet it's happened...[/align][/align][/align]

 

+1 tuning is actualy very easy. If you know the basics of what makes power then its all about trying to get the power as safe as you can.

 

i thought if you got a dyno tune, they give you the handheld because that tuner couldn't be used another car. i guess i am mistaken though.

 

The term "dyno tune" doesn't seem to be well understood, andis often viewedas yet another of those magical sorts things to be held in awe. It isn't, all it means is that a dynamometer is used to guage the effectiveness of changes made to the tune. The dynohas nothing to do withtuning the car, it's just aconvenient method of measuring the effect of changing the tune.[/align][/align]I.e. it'sa faster and "staying in one place" way of doing what you can do with a stop watch and some marks on a lonely road, or a G-Tech type accelerometer, or even the butt dyno (if you've have an experienced one that can separate increased levels of "race car" sound from real changes in power). On modern EFI systems a wideband O2 sensor isa good thing to haveas well.[/align][/align]Onecould make strong argument that for those really in to tuning a dyno tune is just a good place to start...[/align]
