My notes running trevor so far - basically a copy-paste from my own thread.
Day one:
Fitted the unit before heading to work, was quite easy actually. Took a bit more than 5 minutes due to cables needed to be in place. I first planned to start with program 1+1, but as i have been reading a lot on this forum as well as skoda and wv, i decided to jump straight in for the 3+1. All lights turned on, no errors etc - so far so good.
I drove of to work, aprox 25km from here. In 1st + 2nd not a big difference, but those was never the
problem. 3, 4, 5, 6 is where I get the impression of improvement - especially around 2000 rpm and up - you get a smooth kick in the back there.
To work, i got around 52mpg, which was ok, it was quite cold and the box newly fitted. I normally get between 50-52mpg.
Back from work, with a small detour, i got around 56mpg, but it had gotten quite hot during the day, so engine temp was faster up to nominal work temp.
Note: I really would like to know the difference between program 1, 2, 3 and +/- 1,2,3- i don't like the trial an error thing and the manual doesnt mention anything. Why is this information not available ---> Andrew?
I know that its different from car to car, but there must be some characteristics.
Day two:
Basically the same trip as yesterday and the same conditions. A bit less cars on the road today, which also enabled me to get a better feel of especially 2nd. 2nd IS a lot more fun, compared to my short tests yesterday, it really puts you back in the seat
In 6th gear, up hill, at speed around 75-85 km/h, i know i should have shifted to 5th but i compare pre/post here, I however experienced something which i didnt pre-dtuk. There were some un-ease in the engine, as if it couldnt decide whether or not to keep up the speed. Pre-dtuk, rpm would just go down on that hill and you would normally shift to 5th.
As for mileage, the trip to work was 54, and the trip back home was 59mpg, even though I was playing a bit more with it than yesterday and the average speed a bit higher.
So far - I'm still very happy, just wondering
how to explain to wife why the car feels faster (perhaps i will just blame it on her slow seat Mii which she drives most of the week)
Some more days:
Still running like a charm on map3+1, and the setting doesn't seem to have affected the mpg (or km/L) - or the contrary. So far it seems as the mileage has gone up a bit, but I haven't been running on a full tank yet,only half, so can't say for sure and so far my assumptions is based on the computer - which is ~54mpg in total.
I don't know if the DPF regen is beeing active a bit more, but during the past week, I have noticed the cooling fan to be running some while after driving the car. This has happened two times now - but I will have a bit more focus on this part. Can also be due to the fact that the morning weather is a bit more cold these days, and since I don't have that far driving to work - only around 25km - this might be a result of the DPF not getting up to nominal working temperature before I park the car again.
What I like about 3+1, is that the car feels quite "normal" when just driving - which also might be the reason why I havent heard complaints from my other "half". But accelerating and overtaking feels a lot more easy though - and I have the feeling of more power.
