Righto, the Ronbox is in, but I am not too sure if I can identify the FPS and MAP sensor
is the FPF top left of this?
and the MAP here:
The sensor connected tho the "spider" thingy looks like the FPS (fuel pressure sensor) - the 5-way union acts as a common rail - so this is the common rail fuel pressure sensor
The MAP (Manifold Absolute Pressure) sensor is normally in the boost hoses/ pipes in between the intercooler and the inlet manifold the MAF sensor is usually between the airbox and turbo (compressor air inlet)
Once you have fitted the tuning box, they often respond well to an ECU reset (disconnecting the battery for a couple of hours to reset the ECU, so it "relearns"- watch you don't loose your radio code ) -
A fresh air filter helps too (i change mine every 6-months) because the tuning box (basic) "increases the diesel",a good airflow helps to balance this and you don't want a clogged filter - Alternatively (if you must) you can fit a K&N panel filter
The settings on the rover-ron box used to go from 1 to 10 (you have one of the newer 2-channel ones though) - it is easy to assume that level 10 would produce more power than (say) level 9, but that may not be the case - level 10 may just needlessly produce too much smoke - ideally you should test the car in controlled conditions - like testing the 30-70mph (on the same bit of tarmac, same incline/ same weight in the car/ same weather etc) (safely off road, of course ) (with a stopwatch) - if you can find the lowest setting on the box that still maintains the quickest time you have found the best setting for performance and probably economy (maximum performance with minimum fuel used)
PS - im good at finding things, i was searching for something else entirely and i stumbled across the diagram for the mk4 exhaust!
