Nice
I played with the 3 remaps I have for the D3 and the Aliengate interface (I have the std tune, an 'economy' tune and a 'power' tune). Around the city I've found that the economy and power tunes both provide better power and return better fuel figures than the std tune, as they're supposed to.
However, towing the van on the open road is a little different. I did 300km with the 'economy' tune, then 250 km with the std tune. The economy still gives better power, you can use the cruise control and the car will stay within 3 ~ 5km/h of your set speed. Cruise control off makes little difference. Average was 19.6 l/100km
With the std tune, cruise control will vary by as much as 10km/h, and it annoyingly holds onto the higher gears for too long going up hills. But with cruise control off, driving at the same speed as with the 'economy' tune, I got 18 l/100km.
It's a heavy van (2.6T unladen), and being raised, it has a poor drag profile. But interesting that the std factory tune out-performs the remaps!
Cheers,
Gordon
