Quick DieselBooster update 2

As mentioned in the previous post, I tried to set the curve opposite of that the 'tuning' units on the market do. So the reported fuel rail pressure would be higher, causing the ECU to decrease the rail pressure, and, hopefully, fuel consumption.

After a long test test I can say that this is the way to go. Most numbers have been tweaked so that it would result in 15-20% lower pressure.

For mostly highway driving the fuel consumption is now down to 6.28L/100km 7L/100km, with an average speed of 102kph (cruise control set for 130kph). For the same driving conditions, the factory result would be around 7.4-8L/%. This is corroborated by the fact that I was able to drive >1200km with a full tank.

I don't have any numbers yet on city / heavy traffic consumption, it might be a different story.

I don't know the long-term effects on neither reliability nor pollution, the injector nozzle spray pattern might not be suitable for such low pressures.

TL;DR: >15% 6-7% fuel savings with the DieselBooster values set to 115-120%, opposite of the initial ones.

Edit: article was amended after I discovered some miscalculations. I forgot to take into account a mid-trip refueling. New calculation falls within statistical error. This project seems like a fail.

      I have a newer version on my computer with more functionality but it's not up on GitHub since I gave up on the project.
