What we need is to find the original team from LR to settle this haha
they would not know, no diesel mechanical engineer or other engine specialist would... we need to find the original electronists team from Lucas who built and programmed
the ECU cos they know how they made the addaptive strategy as the data from the MAF sensor and the Engine Speed in RPM from the crank sensor are used to determine the
air mass in milligrams within each cylinder on each intake stroke (mg/stroke) cos that's how the
Td5 ECU is built and that's what it does, being a microprocessor not some artifficial intelligence it doesn't care how the diesel engine works while it calculates these things together with the IQ(injected quantity) then it gives the command to the injectors to release fuel into the cylinders based on those calculations, the electronic throttle inputs, MAP/IAT, FT, ECT.....
that dumb ECU uses the MAF readings in it's calculations after the folowing formula:
air mass = (MAF x 33333) / (RPM x 5) and the amount of fuel injected by
the ECU depends on a combination of the air mass within the cylinder and the speed of the engine if the MAF fails to send signal the the ECU switches the calculation and uses MAP/IAT and then the
air mass = (MAP x Cylinder Volume in cc x Molar Mass air (g/mole)) / (IAT(K) x R)..
in this formula the
Lucas Td5 ECU uses the following values:
- MAP = kPa x 100 (or milliBar x 10)
- IAT = Kelvin x 10
- Cyl Volume = 498
- n(air) = 28980
- R = 8314
that's how
the ECU is built to work that's a fact as about how the diesel engine works i dont care as long as
i'm speaking only about the ECU here not about the engine,
what will a remap do? will modify some data
in the ECU(fuel map) as to optimise the fuelling or increase power, so if i go into the ECU and modify some figures the wrong way
that ECU will send too much or too less fuel into the engine depends on how it was programmed cos the ECU doesnt give a sh*t about how the diesel engine was built to work by mr Rudolf,
the ECU will do what it was programmed to do then the engine will run better or worst
... i'll not contest anything about how the engine works cos i'm speaking
only about electronics here that's why i bolded
the ECU so many times
that's it, i'm in the night shift and i have to keep myself adrenalised somehow cos it's a lack of air traffic untill the morning
