Hmmmm..... Very interesting...... Well, here's my observations....
For 2 or so years now, I've been using a pretty slick power supply for my HP laptops.......It plugs into the wall like a regular 110v laptop adaptor AND ALSO has a 12v cig lighter adapter.....
Either way you plug it in, it makes the laptop happy (obviously the 12v is only in the car) and I can tune for hours on end while the laptop stays fully charged...
Kinda neet.... I NEVER have a problem. Even with analog wideband hooked up.
Now, that being said..... A word of caution to
ROADRUNNER users.
If using a Roadrunner, and a wideband (LM1 in my case) analog style..... the moment I put my 12v laptop adaptor to the laptop....You hear a pop and the car instantly shuts off....and the Roadrunner pretends it's dead like a dog on the side of the road. The car won't run until you do the RR MASTER RESET and reflash the cal.
Kinda spooked me the first time. On the phone crying like a baby to Craig for help.....
Lesson here....If you're gonna use that spaghetti of wires setup like I do.... It's best to fully change your booster pack and put it in the passenger compartment to run your inverter power supply.......
I don't think mine is actually an inverter....I believe it's just a transformer....Am I right?
