Got to put the TS chip to the test today! And I am very happy with it!
I have just driven around in the city with it until now but today I logged a few hundred highway miles... We went out into the bush today to grab some firewood.
For the drive out, I had my brother in law tow the trailer and atv. My van was towing nothing and just had my family inside. With the TS chip on 100hp, I got 19mpg! This is up from around 15-16 that I used to get on this same stretch of road.
On the way back, I towed the trailer with the atv in it and a partial load of birch firewood (total weight of around 2500lbs-3000lbs). The van barely noticed the extra load and I got 16mpg with the TS chip on the 75hp setting.
I would like to try the same test again with the chip on the 100hp setting both directions but I didn't want to risk it until I get an EGT gauge installed.
But I'm pretty happy with those mpg numbers... This chip will pay for itself quickly I think.
