Spends too much time on here
No doubt etorque saves money in the city. But I wouldn't base the exact amount of savings off of the ECU, they can be unreliable. You would have to hand calc that, or run a test that lasts 2 or 3 full tanks for each truck.
My truck will drop MPG very quickly when I remote start for 5 to 10 minutes, but yet at the end of the tank I haven't really lost anything compared to when I didn't use remote start even though the ECU will bounce around a little every time I use it. For some reason I find myself using it a lot lately, must be getting old.
I hand calc'd my truck on every tank, for the 1st year and I've never been more than .30 from the computer in either direction.
This trucks calculations seem to be a more accurate than my 2003 was. I get 415 - 430 every tank driving in Dallas and refill with 23-24.5 gallons.
At this point, I can simply look at total mileage for this tank of gas and how much fuel I refill the tank with and roughly know what my mileage is without even hand calculating it because I've done it so many times. I check it in the calculator about every 2 tanks but have been watching it more lately because I replaced the stock Goodyear 22s and wanted to see if there was a change.
These tires are slightly heavier by about 3 lb per tire but they have a higher treadwear rating which would make them a little more fuel efficient than a goodyears, so I've been keeping an eye on it.
I really didn't care about etoric, didn't really want it and had no interest in it but the limits that I found all came with it. Once I started researching and reading on what etoric did and watching the videos I decided that it probably wasn't a negative for me as I do far more city driving than I do highway driving.
