need expert advice
ok i know what a handheld programmer is.. know how to work 1.. my brother and my friend programmed there's 1 used diablo the other used hypertech.. what i don't understand is the difference between that and a tuner like efilive or ls1edit or hptuner.. i keep reading stuff like it's software and u need a laptop.. how exactly does that stuff work? how does it hook into ur car and how do u use it? i see it's pretty expensive but offering things like free upgrades for life is definitely worth it...
efilive/hptuners: very versatile...you control (almost) every parameter and table. this can be a bad thing if you don't know what you're doing. if you've made any kind of major mods and want to compensate for them so you squeeze every bit of HP out this is the way to go. a canned tune can't possibly know that you've done a 228/228 cam but not heads, know the exact airflow capabilities of your exhaust, etc. software will allow you to log and adjust and tune for your specific car.....but since you insult those that spend time on the boards this might not be the thing for you to do if you're not willing to make the time commitment to learn. that will take time on these boards. it takes awhile.
ls1edit: general consensus: it sucks....spend your money elsewhere
He called me a nerd...
