Needed to calibrate the odometer for 35s. Worked and was easy to do. Took about ten minuets.

I was very pleased with the E-CON. I installed it on my wife's 2011 Expedition. I wasn't concerned about the 40 extra horses, but bought it to improve my mileage. I checked the mileage on several trips without it and then with it. By the vehicles mileage indicator, at 70 mph on cruise, I got a 2 mph increase, from 20 to 22mpg. What surprise me was at 75, the mileage went from 18 to 21.5mpg. If you put the pencil to it, the E-CON will pay for itself within 10,000 highway miles.

plug and play...this tuner literally unleahed the beast in my Silverado. I deleted the AFM system, set shift firmness to 50%, and tires set to 35"!! She RIPS down the road now. No irregular shift going downhill!!! THE MOST IMPORTANT is my MPG went from a dead on 11.5MPG to 15MPG. ALL is perfect now!!! BUY ONE< YOU WONT REGRET IT!!!!!!!!!
