Hello,
If you get your car chipped by say Hill Power they just drop a chip in thats modified to your cars mods. But if I am understanding this correctly its just a different map that they put on depending on what you have had done. So its not actually perfectly setup for your car. So you get a chip thats fully programmable that can be setup just like you want. So then people go on about putting your car on the rollers and setting it up. Is this just simply setting up the fully modifiable chip or is it something different? Also is it possible to get a chip installed by hill power then altered on the rolling road (if thats what the rolling road setup actually alters)? Then you can get these piggyback units, which as far as I can tell just sit ontop of your original chip and tell it to ingnore everything it knows and do what it says. So whats the best way to go about this?
Paul
