Anyone know anything about the Lucas EPIC system?
specifically, should it have restricted power when the engine's cold...
this morning, it wouldn't pull above about 3000 rpm. after a bit it went back to normal.
It did also not pull as expected when up to temperature, once. Wonder if the throttle pot is iffy? If it's not getting a "full throttle" signal at full throttle, then it won't go...

and by the by, if I fit an intercooler to one not thus equipped, does it have to be remapped?
Dunno about the PRINCE OF UNEXPECTED DARKNESS systems Austin on the Mercs if you try to open the throttle too early during the diagnostic cycle the system restricts the revs until you return to idle and it completes its run. Derek
My transit didn't, not noticeably anyway.
The throttle pot is actually 2 pots, working in opposition to each other, as you press the throttle, one increases resistance, while the other decreases. If it is faulty then you should get a engine management light showing, as it would detect the fact that the pots did not agree to the position.
Check the obvious stuff first, filters etc.(if you haven't already)
Possibly! The pump will detect the cooler air, so calculate the higher mass so add more fuel, but it may run out of range of its preset parameters before you get the full benefit of the cooler.

Good point - no light, so unlikley to be a faulty component. I'll see what happens this morning.
air filter done yesterday afternoon, diesel filter to be looked at shortly. But it's not obviously short of power in general.
yeah. The intercooled ones have a "charge temperature sensor" instead of an "inlet air temperature sensor" (or so sayeth the HBOL), the latter is on the airbox on this one. Dunno if it plugs into the same wire. The intercooled ones have the sensor after the cooler, which makes sense.

behaved perfectly normally this am. must have had a strop on for some reason.
I daresay it'd not hurt to chuck a can or two of injector cleaner through it, although the modern clean diesel doesn't seem to cack things up as much as the old stuff did.
