I have run a drive test on the new prius 2016.- it is more responded to the gas pedal. it accelerate faster and the car fill less heavy. I s there a way to update the Gen 3 - main computer with the new SW controlling the new Prius ?
You can buy this after market component called Apex I. I believe it sells for around $150.00. Hooks up underneath dash with 3 separate buttons next to each other you mount on your dash somewhere. It re-calibrates computer to ramp up faster. However, I have found the Power mode that comes stock on mine more than enough.
welcome to priuschat! i don't think the software is the issue. were you in the 0-30 range, or 30-60? all the best!
