On newer cars the Engine Control computer may be "intelligent" this kind of computer understands that the engine is ever so slightly different from any other engine ever built and makes very tiny adjustments to timing and fuel and perhaps some other things to maximize efficiency. IT may even learn how you drive and make adjustments accordingly.
Disconnect the battery and it looses it's mind and goes back to factory defaults.
As the help started to roll in, my DW was the first to realize that the Brake Buddy needs to be plugged in to our cigarette lighter.
I think I'm leaning toward a system recharger (for the Brake Buddy from the Brake Buddy website). That's what I'll look at when we get home in a few weeks.
Is the Brake Buddy charger available in one of the RV stores?
This website is awesome. A user can ask for help on something and then sit back and sort out all of the attempts to be helpful.
