Maybe, but a few things about that:
- In cold weather like yesterday the duty was 95%, normally it's in the low 90s.
- The injector duty spikes to 95% only around the transition point as it is the most critical and dangerous part of the map. 3,500-5,000 RPM to ensure there is enough fuel there at all times. Everywhere else in the map it's closer to 90%.
[li]I asked several tuners in the UK (Hayward, WGT, Rotor Torque) before deciding to push for over 1.0 bar on the stock fuel system, and every single one said that they have never seen injectors fail or get stuck open even at 100%.
Now, that's not to say I shouldn't have a little more headroom but then I'm not 100% sure that even matters. I don't think the Power FC is smart enough to recognise an underperforming injector or low fuel pressure and supplement those types of issues to inject even more fuel. It just reads from pre-loaded fuel tables with temp correction factors to inject more or less fuel depending on intake air temps. So, if an ancillary like a fuel injector fails it is going to pop anyway.
But please tell me if I'm wrong?
In any case, I won't be boosting much in the cold weather as I won't be driving it when the salt arrives so I should be okay. If not, well it's my fault then but I would rather run just under 1.0 bar than swap out my secondary fuel rail and make all of those mods for overkill 1650s.
