After a round of testing out last night and this morning on my way to work, i tried 3 different modes for my 118i.
I had to wait till about 8pm when the roads are clearer before testing this out in sports mode.
In Sports mode, there is definitely an increase in power bringing me from 0-100 in a much shorter timing given the better throttle response. I obviously did not time it but i can feel a significant push forward when i put my foot to the pedal, with the increase power, overtaking is a breeze.
My drive to work this morning.
In Comfort mode: Given the amount of traffic in singapore, comfort mode is my ideal mode of driving around, however i dont feel much response from the swiss chiptech esp in comfort mode. I consider myself to be a regular footed driver, not heavy footed, but i dont feel much response when i'm driving normally, but with a slightly heavier touch, it probably does give it a bit more boost than usual, esp from stationary position. Im blaming this on the run in, i'll give this a second chance after running in more.
My drive home last night:
Eco Mode:
A definite increase in power, with better throttle response, it decreases the lag time and my ECO mode feels like comfort mode now. Before swiss chiptech, whenever i was in Eco mode and stationary, i have no power accelerating from a red light, losing out to most vehicles adjacent to me, thus putting my pressure on the pedal causing my Eco indicator to tell me to pull back. But now its so much better. I can continue to use Eco mode and save some fuel money in the long run with this piggyback.
Overall: a value for money upgrade for the increase in power.
