Hi folks,
Anyone know what engine speed the turbo's supposed to kick in on the
If it is kicking in too late, is it something that's fairly "easy" to fix (e.g. a setting in the engine management unit that someone at a Ford dealership could change in 5 minutes)?
Thanks in advance,
Stu
the turbo boost is controlled by the ECU and therefore it probably is not just based on RPM but what ever else the computer decides is relevant ( gear selected/ throttle position / day of week .. ?) Mine only seems to kick off between 2K and 3 K, so yours is probably normal. I know what you mean about changing gear all the time, it's a pain isn't it, see my other post today re. overtaking
:)

Your car is behaving normally. This is the problem with a fairly hightly tuned turbo diesel without a VGT.
Tturbo is too big to spool up until there is a certain gas flow. Gas flow is directly proportional to engine speed.
Using a smaller turbo would strange the engine at higher revs.
Alot of manurfacturers are using VGT's on their more highly rated TD's...

hmm I remember reading in the Haynes book that the ECU controls somthing in the turbo is it the wastegate ? Is this different from a Variable Geometry Turbo ?
Completely.
Tim..
To set the record straight, the tdci Focus DOES have VGT '( Variable Geom. inlet vanes.. ) Unless the HBOL is totaly wrong.
