My Ride: Needs a'fixin'!
|
I've had my headers for a while and someone said to reset adaptation values?
Searched, didn't find a clear-cut answer.
I always thought the car would "learn" to operate as time went on, but I was informed that resetting the adaptation values will really change how the car drives (for the better). I had to scratch my head and give a funny look since my car runs like a champ right now (walks a ZHP, I know for sure). Would this actually do anything or would it just be a waste of time? I am planning to get an 02 simulator and probably go with the Shark Injector (since Active Autowerke's prices are too rich for my blood and I've been reading the Shark will result in higher gains, even though AA claims to "custom tune" to your mods), so I'm wondering if resetting the adaptation values would even be necessary. Some clarification would be great.

waste of time. sit back and thinkg about what reseting adaptations would do... answer that yourself and then think what the car will do after you drive it.. hopefully you answered your own question.

You are right the car will adapt all by itself as you drive it. You can speed the process by disconnecting the battery so it relearns from scratch.
In terms of throttle adaptations, all they are is the computers adaptation to how much throttle your likely to ask for. So the computer interprets your pedal position and depending on how sedately or not you drive, it will give you more or less throttle or exactly what you asked for. If you floor it, it always gives it all. My car always feels slower after my wife has driven it for a week. In reality, some of it is fuel trim and ignition timing adaptation which will rectify on its own once I get my hands on it... and some of it is just throttle response to inputs. Pretty soon, once I've been driving it, a blip will practically mean the computer thinks I want full throttle as always
