How to reduce "target pressure of fuel in rail". TSI FSI engines.

[Gurom]

Dear Friends.

My main business is convertion of cars to LPG fuel.
During of working with LPG fuel we need to reduce the pressure within of gasoline fuel rail. The ECU of car use the special variable "target pressure" .

The curent solution is simple:
We use the additional emulation device to reduce the pressure in gasoline fuel rail. We connect this device to the sensor of gasoline pressure . Emulation device inform the car ECU that pressure is high, but the real pressure is low (25%)

My question:
Can we change the value "target pressure" via ECU car tuning?
Such solution will work much better.

Thank you in advance
Roman

Dear Roman,

Welcome and thank you for your posting.

I am not sure if i understand you correctly but it should be possible to do it via the ECU but we don't offer this so we don't have experience with such a modification.

best regards
