I talked to Mark Adams at Tornado systems. SO far he is the only ECU tuner on the Bosch 5.2 Land Rover. He supplies the .bin files for RPI if not mistaken. Unfortunately, you have to send the ECU across the pond for the flash. Note I said on the Land Rovers. The Bosch 5.2 is also used on BMW, Porsche, Ferrari and others. These autos use a similar map table as the LR does. I have modded the ECU fuel/ignition curves and may supply them if interested.
Reading Mark Adams thoughts on the fuel map, it is suggested to be to lean in the mid range. Looking at the tables can provide some insight if one wishes.
The Land Rover is not very high tech. This stuff is common knowledge.
