Ok this might be a dumb question. Is there anything I can buy or do to store tunes on and quickly change on the fly? Like when you buy a tune from say 5 star, you have multiple tunes and it's just press a button and it changes. Or do I have to hook up my laptop and hp tuners and flash my tunes each time?
I think only the diesel computers from GM and maybe ford offer a little switch. It's on the website I believe.
Nothing like that is there for any gas cars as far as I know. But there is really almost no need for different tunes because you can pretty much do everything in one calibration file these days. With flex fuel sensors and all the extra tables in the newer computers it's pretty seamless.

2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
Ok that makes sense I belive its been only diesels I have seen that on now that you say it. I was mostly curious because I drive the Alaskan highway often where there is no data or wifi available and I was looking into water meth but want to be able to change the tune with out data in case there was a problem with the system. I figure a tune change would be the safest easiest rout from going lean in case of a water meth malfunction or problem.
All you will need is a laptop with tunes and HPT. I’m not saying its the way to handle this but it can be done.
Don't I need internet each time to flash a tune
I guess that might depend on what you are tuning. Maybe. And maybe the new 3 is different from my 2. I’ve never been connected to the internet while loading a tune.
No, just the laptop with tunes saved on it and your HPT and cable.Originally Posted by rockofthenorth
Depends on the year model. Newer year model GM's and Fords for instance require you to be connected to internet before you can even open them on your computer. Once open you can do what you want unless you want to open another "like" tune to compare to - which also requires internet hookup.
