ADAPTIVE TRANSMISSION EXPLAINED

so back when i did the video showing all the different features and tips and tricks of the mercedes w204 c300

i added in there how to reset your TCM throttle control module aka TPS throttle position sensor reset

because newer cars now have a drive by wire system where 
when you accelerate, its ends a signal to the ecu 
letting it know how much the throttle has been depressed and therefore 
sends a signal to the throttle body letting it know how much to open according to 
the percentage you depressed your accelerator pedal
now alot of ppl have been saying its a ecu reset, but that is not true
this procedure does not reset your ecu
to be exact it resets and restores your your TCM to factory settings 
so that your car can relearn your driving style

and this is a bonus for many different reasons
some are 
re-learning your driving style as you may not drive as hard as the previous owner
if you have a light foot, then this would be a bonus 
leading to saving fuel as having a heavy foot would tell the ecu to change gears at a higher rev
meaning your car would drink more fuel  
hence you would save fuel by doing this reset
throttle response time will change 
and will adapt to your driving style

so in short there are definitely benefits to doing this reset especially if you are buying a used car 

1. get in your car
2. close all windows 
3. make sure all accessories are turned off radio, headunit, heater, fan etc
4. close all doors 
5. insert key 
6. turn key to 2nd position (on) before you crank the engine
7. depress accelerator pedal all the way down (hold for 5- 7 secs)
8, continue to hold accelerator down then switch off car
9. leave key in ignition do not remove key( whilst still depressing gas/accelerator pedal)
10. then you can remove your foot from the accelerator pedal (gas)  
11. do not do anything at all for the next 5 mins (important) 
12. you should here a very quiet electrical sound confirmation like a clicking sound (so im told) 
13. once 5 mins has passed, your DONE
14. start the car, let it idle for about 2 mins
15. take it for a drive, at this time its important that you drive the way you normally drive so the the car can adapt and learn your driving style
this is what we call a throttle reset 
allowing the ecu and throttle control module or position sensor to re-learn and adapt to the way you drive

some ppl might do this reset for time to time just to be sure that the car is always responding and adapting to their driving styles

however in my honest opinion doing this once would suffice for a long period as 
it will adapt and learn your driving style...so if you are the main driver of the car...
constantly doing this reset wouldn't be necessary once a week more like once every 3 - 6 months
however it is your choice it wont hurt the car in any way
