I then drove the vehicle for a few kms.
I then reran the test (for the fourth time) and again got "No error codes stored in the ECU" (for the second time in a row).
Ambient Pressure Low is common, and will appear even when the circuit if fine...
Its to do with the AAP sensor in the Airbox, not the Modulator for the Wastegate.
Dont bother writing a VIN...
Just went out and check with the Nanocom Evolution - DISCOVERY II / TD5 / TD5 ENGINE / SETTINGS / INJECTORS - THROTTLE:Quote:

So it looks like it is correctly set to 3 track accelerator potentioner type.
Whilst I was in there exploring other features of the Nanocom Evolution, I tried some of the following:

DISCOVERY II / TD5 / TD5 ENGINE / SETTINGS / OUTPUTS:
- TEST AC CLUTCH - working.
- TEST AC FAN - working.
- TEST MIL LAMP - working.
- TEST FUEL PUMP - working.
- TEST GLOW PLUGS - working.
- PULSE REV COUNTER - working.
- TURBO WATEGATE MOD. - ECU Communications Error - this is likely due to that it is disconnected and removed due to the VNT upgrade.
- TEMPERATURE GAUGE - working.
- EGR INLET MODULATOR - ECU Communications Error - this is likely due to that I have removed the EGR system.
- INJECTOR 1 - error - see below screen shots.
- INJECTOR 2 - working.
- INJECTOR 3 - working.
- INJECTOR 4 - working.
- INJECTOR 5 - error - see below screen shots.

The above screen shots are of the errors I received when testing Injectors 1 and 5. I tested them while the engine was running. The other three all tested as working.
Isn't the factory spec on the stall test around 2800 rpm?
Have you tested the fuel guage? I had an issue in a previous car where the fuel guage said it was empty but it still had a good 200 k's still in the tank...

indicates reduced engine power.
A reading above 2800 rev/min (Diesel) indicates clutch slip.
NOTE: The figures quoted above were
measured at sea level with an ambient
temperature of 20°C (68°F). At higher altitudes
or higher ambient temperatures, these figures
will be reduced.
Not sure if an upgraded ECU will give a higher reading but I expect not ??
2,600 - 2,800 RPM, but a factory vehicle does not have a VNT, larger intercooler, increased boost pressure or a more aggressive ECU tune. So really, the stall test has only shown that my vehicle is making more power than the factory setup (as stall speed increases with increase in engine power) - I already knew this...Quote:

JC or Blknight ??
Hi all,
I´m looking at the fueling inputs...
Can someone with a nanocom please send me some fuelling readings of a disco2 with auto gearbox? It can either be a remaped one or an original!
Im very interested to see the Engine speed @ some diferent situations and when the gearbox changes gear...
Overhere they are almost all manual so I canot make those acurate readings myself!!
Thanks in advance!
Regards
Hello,
Just read this post, that is a lot of fuel you are using, I get more than that to 1/2 a tank last tank 540ks half a tank. I have a VNT, Ashcroft TC, 3 inch straight through, and LPG injection 25%, a great TD5 inside map.file, now I did have a bad patch about and month ago, and brought a new MAF and even better. Is your getting limp mode at all ?? Maybe a compression test is need as that fuel has to go some where and if lots of smoke means it is burning. My MAF was reading right, bit using lots more fuel.
