I really want one of the ME (Max Energy) things. I found $100!! I'm like 1/3 the way there....

Jeff, how hard was it to use? Do you HAVE TO HAVE a Windows based PC for it?
I'm SURE I'll txt you for further instructions once I have it in my hands!!
Well ill take a crack at this lol. Sorry to steal your thunder tho Alex.

A tune even in stock form, is a set range of parameters loaded into the PCM that are used to run the engine. They include things like spark timing, fuel injector timing, coolant temperature, cam and crank position and throttle position.

A aftermarket tune is basically these parameters modified to be more aggressive in order to gain power or fuel efficiency. Canned tunes are just that. While they are more aggressive then stock, they too are just a preset configuration. A custom tune, is a tune done by dyno's to get the most out of an engine while still retaining the optimal air fuel ratio. Its tuned through out the entire rpm range and load.

Now a programmer is whats used to load the tune into the pcm. You can load a tune without some sort of programmer whether its a handheld like the hypertec or by laptop.

The Hypertec is actually fairly simple to use and all your doing on the computer is registering the programmer and locking it to your vin. Once its locked to your vin, they will send you by email, the tunes to load onto the handheld. Then just follow the step by step on the handheld and your good to go.

Well it doesn't have to be done on a dyno, it can be done while logging on the street as well. The dyno is usually only used for WOT tuning which isn't recorded by the cars o2's unless you purchase a set of wideband sensors. However most tuners can get perfect air fuel ratios by just looking at the ratios at other rpm ranges, so if anything the dyno is sort of a double check.

Not for fuel economy you need to tune on the street at part throttle even for performance bro.

Fuel economy? What the HECK is that? I don't give a DAMN about fuel economy! lol. Alex is right. More powwwwerrrrr!!
