Well, I uploaded the 5-star tuning RV map, using the Livewire TS 5015 unit.
We've been on a trip from Houston, TX to Johnson City, TN and then down to Savannah, GA and I have been pleased with the results. Once into Mississippi and through the Smokey's and back out headed towards Savannah, we were constantly going up and down grades; some pretty steep.
Where the transmission would incessantly downshift at the slightest grade with the stock map, it will now hold in 5th if I am going between 60 and 65 mph. If I am travelling at 70 mph, I can expect a downshift but a couple of clicks on the "coast" button will prevent the downshift. I assume this is due to the extra HP from the map and a change to the shift points.
What I really wasn't expecting was an increase in mileage. Last month on the trip from Houston to Fargo, ND, I could never get better than 7.5 mpg on basically flat terrain. This trip through the mountains, I gave consistently gotten 9.7 mpg. Now this isn't totally an apples-to-apples comparison because on the Fargo trip I was towing a Jeep Wrangler and on this trip I was towing a Triumph Tiger on a motorcycle trailer. For my next trip with the Jeep, I still expect at least 8.5 mpg.
It was well worth the cost to me.
