Td5 engine readings

Does anyone have a list of what readings one should expect for a "healthy" engine (via nanocom?)

I've got the readings to tell if the MAF sensor is dead, but was wondering about the other sensors and readings.

Cheers

I haven’t, but have a Td5 and a nanocom, so if you list what you want/have I could plug mine in a give you my results/readings.

I have note in the case for the Nanocom. 55-61 at idle is what I have noted as being good and should increase with revs. 1999 Defender TD5 110

Isn't the injector balance at idle meant to be +/- 5 ?

This would be a great list of normal values to have as a sticky for the group!

Re: Td5 engine readings

I have recorded some readings on my defender. at sea level climbing a small slope.

MEASURE 1
AT 90 kmh, 2389rpm,
acc track 1 3243
MAF 348
Turbo 177.6
Air inlet temp 39C
Coolant temp 83C
Fuel temp 65.4C
EGR Inlet 26 (but is blank anyway)
cyl +2 to -5, but is not a good reference with an accelerating engine, should be compared at idle.

MEASURE 2
AT 90 kmh, 2375rpm,
acc track 1 565
MAF 212
Turbo 110.5
Air inlet temp 41C
Coolant temp 85C
Fuel temp 65.4C
EGR Inlet 0(but is blank anyway)
cyl +3 to -4 Augusto
