  1. Hey man I was running that E30 1989 E30 that I had for the last 8 years BMW M30B35 swap - 3.5 liter straight six with Haltech management and a custom tune, coupled with the original 5 speed Getrag manual, LSD, fully rebuilt chassis and body from ground up, and most importantly, launch control :D!

  2. what do you mean by automotive engineering? You can be a automotive"technician" but not an "Automotive Engineer". The Engineers who are involved in Automotive product development come from different specializations such as Electronics, Mechanical, Industrial, Software engineering Base Degrees. There is no way one "automotive engineer" could have enough knowledge to design a car alone, its too complex since 40years or so when electronics and software entered the scene. However, a proper background in maths and physics is mandatory to be an engineer working in Automotive design (Military and Aerospace design fall into the same category) The path of getting a HND or diploma and continuing to Bachelor degree does not work in Sri Lanka,because there is no Automotive Industry here. 1st thing OP should do is to do a Bachelor in Electronics or Mechanics,(better go to a country which has any Automotive industry, even in India or Malaysia) and go for a Master of mechatronics in an industrial country (Germany,France,Sweden, Netherlands,Japan,Italy..) like many Indian undergraduates do nowadays. If you can stretch your budget, UK or US is also a possibility.

  3. Although it's a simple calculation, the necessary hardware needs to be available in the car to carry it out. The fuel tank's float or level sensor needs to take into account even minor changes (increases) in the fuel level after a partial fill-up. But I don't believe they're designed this way on the vehicles in question which are regular inexpensive road cars. Instead, the float/sensor can only detect when the fuel level has a substantial change. To add to this, modern cars with digital fuel gauges use variable resistors and a small bit of circuitry to calculate the level of fuel. This also takes into account some dampening to avoid moving the gauge all over the place when the car goes around a corner or over bumps and causing the fuel to slosh inside the fuel tank. So it's possible a partial fill up just falls within the threshold of the dampening as well. Only a fill-up that exceeds the threshold would be considered a fill-up. None of these issues exist in fully electric cars, thus being able to provide a far more accurate range.

  4. I'm pretty sure the Prius manual says that adding a small quantity of fuel will not update the range. Not sure what "small quantity" means here, but I assume you need to add at least quarter of a tank for the system to update. So try putting in a full tank of fuel and that should update the range. As for shutting off the engine while refuelling, this is the right practice.
