Afternoon,

Would like to add a fuel pressure guage to the car. Not so keen on a mechanical version in the dash so has anybody installed a decent sensor fit for purpose (0-5bar range) they can point me towards?

Cheers,
Lee

Thanks DCL, it was the Stack unit I was looking at.

Interesting what you say about the change in pressures though, that does indeed make a difference to the value of having a guage in car. I have the ability to measure inline from the engine bay so maybe will stick to that then.

Cheers again! smile

Pretty sure DCL is not implying this is an 'automated' ECU option that adjusts the timings in real-time with fuel pressure. Rather saying the maps account for differing fuel pressure (and hence injector timings) at varying rev / loads when they are defined on the RR.

Also, if you are maxing your duty cycle then you need to review pressure, injector capacity, etc. What's your setup?

Picos? If the beige'y brown then these are the 330cc ones, same as I have. I've just shoved an adjustable FPR in ahead of an RR session with Dave on the 17th and plan to run somewhere between 3-4bar. Will let you know how I go.

Was up there last week but it only made 245bhp as opposed to the expected 265bhp, traced to fuel pump dropping off significantly to circa 2 bar. New one in now so hopefully problem solved smile
