FiberHome AN5506-02-F router hack

I recently had to work with a home fiber router that was supplied by the ISP,  the FiberHome AN5506-02-F. Compared to the previous internet access solution, which was based on a cable modem and required the user to use their own router, the new solution has both advantages and disadvantages. The advantages would be: integrated WiFi, security and firewall. The disadvantages: only one LAN port available (@100Mbps), only 2.4GHz (@150Mbps), outdated software, locked-down interface, no easy way to expose a second router. The unit is very similar to the AN5506-04 model (  http://flytec.com.py/download/files/AN5506-04F-manual.pdf ), except it has only 2 UTP ports, only 1 phone port and no CATV interface. Exposing the inner router To get around the issue of the (old) router not being accessible from outside, the solution is to add that router into the DMZ setting. This is needed for things like web hosting, ftp server, some chat clients, torrents, etc. You can log in with ...

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-...
