Fuel pressure Lancia turbo
Hello guys.
i'm working on a Lancia 16V turbo engine with the magnetti marelli IAW 4WG/P8 ECU.
Does anyone know if this ECU is able to adjust fuel injection times accordingly when the fuel pressure is increased from a 2,5 bar model to a 3 bar model.
In other words, will it recognise there is actually more fuel injected and offset the fuel map?
Reason i'm asking is that i have to drive a couple of hours with this setup before arriving at the person who will remap the ecu and i'm scared of overfueling, dilluted oil and bore wash.
Thanks for the help.

Personally I would swap pumps when I get there.
When you double the fuel pressure you dont double the fuel, the increase would be less than 5% increase between 2.5 and 3 bar.The ecu under lambda control (less than 4k rpm) would be able to adjust for this, it may be alittle rich but within tolerances of the engine at worst.
Don't drive it hard..
EDIT
You should have a regulator at the engine end so would still run 2.5bar until this is adjusted.

In short, no. Not on its own, it needs remapping for that.
Without having details of what you have done and why you are expecting 'overfueling, dilluted oil and bore wash' I'm sorry, it is impossible to provide any further help.

Xavier, hi
There is a simple answer to this. Unless you want to risk scrapping the engine, do what I would do and get a trailer and take it to the dyno on a trailer.
This does not answer your question, of course, but that is nether here nor there!
Never drive a car when the fuelling (or ignition) calibration is suspect, period!
