Fuel pressure sensor setup
Discussion
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!

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?

Northampton Motorsport Engine
-2019cc over-sized (Duratec)
-88mm Omega forged pistons
-12.6:1 compression ratio
-Saenz HB con rods
-ACL competition bearings all round
-Head gasket 0.6mm cushed
-Neil Roper developments hand ported high-port head
-Piper cams double springs
-Piper cams BP 300 cams
-Cam timing: 102 inlet, 104 exhaust
-Crank, flywheel balanced
-Head skimmed 0.95mm
-Increased inlet valve pockets
-Standard crank keywayed
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
