Not quite true. VE analyse live is an extra feature that you have to pay for. Makes tuning quicker too if you wanna use it. As far as I understand, it's muck like the mixture map that I posted up in my thread about. If a tuner's playing it with it, he'll know how much to adjust cells by and having it strapped to a dyno and being able to adjust it pretty regularly is much nicer than the likes of me tuning off logs after a 5 minutes drive on the street.
Adaptronics and vipec software are free though since you payed them for it as you bought their product. The MS software (Tunerstudio) is written by some guy on the forum. He makes the basic version free so that MS isn't prohibitive but you gotta pay for the nicer features.
You can do MS plugin but it's gonna be MS2Extra, not MS3 like I have. But MS2E will be plenty for you because you don't need PWM idle/boost control/NOS/2-step/water injection control/5th injector/blah blah. You probably want to pull the loom out and add extra wires for sequential injection and ignition though. Pretty sure Kaizen garage (site sponsor) or adaptronic themselvs can do patch harnesses for bluetop 4age. If not, I'll make you one. For adaptronic/vipec/MS/haltech/whatever.
MS software is pretty simple to use. I freakin' hated the vipec software at first but I've gotten used to it now and although it has its quirks, I'm pretty happy with it. Any tuner who's actually any good should be willing to give it a shot. BUT don't buy one til you get tuner's go ahead.
