Effuel Eco OBD2 Reviews it on two vehicles with two tanks of fuel. it does play into the vehicle computer system as instant display was constantly up and down with numbers when it typically was still on one number for fuel consumption especially at idle and traffic light stop.Not sure it made any real changes in economy or performance/efficiency.Was cheap enough to try though so I'm not totally disappointed.Click Here https://www.wfmj.com/story/42871205/effuel-reviews-scam-or-legit-the-best-fuel-control-system
