How to driving with load or DWL not understanding

[guest001]

I was surfing the forums on ecomodder and came accross this technique, but I was unable to find a super specific description of how this works.

My guess is would be coming up to a hill maybe or maybe not picking up a little momentum then once on the incline keeping the throttle steady and letting your self slow down, not increasing speed/using more power.

usually I'll pick a gear based on my approach speed. and try to keep a pretty consistent throttle.
