So as promised I had my first test drive a few minutes ago, only 5 miles but can confirm all good and I didn't break down.
It was around the back roads where I live but on one straight I was able to get up to 60mph and the car feels very similar to a TD4 as far as acceleration is concerned.
Here are a few findings.
1. It will pull away in third gear but is happier from 2nd.
2. I will use 4th if over 30mph and probably will change up the gears as normal as the transmission becomes a bit noisy at high rpm.
3. Changing gears is very easy as I don't have regen yet. I just lift off the throttle as normal and the gears slip in nicely.
4. I need to tweak the brake boost as it is a little under boosted. This is easily done by an update to the Arduino that controls it, I had deliberately turned it down a lot after the previous problems and may have gone too far.
5. The motor temp rose to 25C at one point so that's something I need to keep an eye on. Maybe I should turn up the coolant pump a little as it is running around half speed atm. Tweaking the software on the same Arduino should fix this however I was driving slowly in high gears much of the time so maybe it is OK as it is. I'll try driving on main roads for a few miles and see what happens at higher speed.
6. The alternator motor driving the power steering is a little noisy. This is mostly due to the ebike controller running in square wave mode as I don't have hall effect sensors on the motor. This is something I knew about and should be able to resolve but that's a project in itself.
I took some video footage and will put up a link here just for Landyzoners.
