I purchased @kennethnilsen69 powerbox at the start of the month and waited for Customs to release it - I finally collected it on the way to the airport so wasn’t able to install and use until the end of last week and use in a practical sense until yesterday.
Firstly, its well packaged and using the guide very simple to install and use. All of the images are accurate and very quickly you can be up and running.
I drive the Twizy 16 miles each way to a station, which takes about 30 mins each way. Some of that is on fast A roads and up to now I have always felt a bit exposed at 50 odd MPH with large things going past. On the way home, I take an earlier junction to go the back way and avoid sitting in this.
When I did the install, I went for the medium tuning and left it on Automatic. I took the car for a spin around the block and WOW - pulling away felt so sharp and responsive. We went on an extended drive and I got the car up to 68 mph pulling about 7,500 RPM with the engine temperature all good. I felt much more comfortable in traffic and even managed a wheel spin pulling out of a corner (unintentionally I might add).
This was great, but what I really needed to know was if this extra performance was going to kill the range to a point where I would not be able to make my commute.
The answer is I made it with a bar to spare. Normally I have 2 bars left when I get home, and occasionally just drop into two from three. Yesterday I just dropped from 2 to 1 bar and expect the same today looking at my half way position.
In the last two weeks as well, Kenneth has been great with emails and software tweaks (already on version 1.3) which again are simple and quick to install.
I did try a spin last night with max power and that was very quick off the line, but for the commute I have gone back to medium.
If you want that bit of extra performance, then I would highly recommend the investment in this.
