Injector Flow conoensation Mode: None vs Sensed Fuel Rail Pressure

Post by KiK »

Hello all,
I am not sure if this the correct board to post this on but here it goes.
I have an adjustable fuel pressure regulator fitted in my rail, vaccum actuated. Which means, in theory, that I can run "None" on Compensation Mode.

On the other hand, as I have a fuel pressure sensor, I can also select Sensed Fuel Rail Pressure which, at least to me, sounds the way to go for a slightly more accurate fuel delivery.
This is on a boosted build.

Any thoughts?

I also have been wondering this. I have been running none tried sensed briefly and ran into stuttering issues at high rpm.
Then there's the pressure sensor type absolute or gauge that changes the base value for calculation.
Throws everything out if you have it set wrong.

I think everyone moved to discord. In general a vacuum correct regulator and fixed flow value works fine. The advantage of reading pressure and using the associated flow rated is failure or drift correction. I had a failing fuel pump and fuel pressure was down to 10 psi before it was clear I had an issue which is good but I did added fuel pressure to the warning light triggers. Also on a setup like mine with ITBs there's no good way to vacuum correct the regulator so a pressure sensor is helpful.
