94 octane in Canada varies alot from fuel station brand to fuel station brand, some Canadian 94 acts like US 91. Some act like true 94 and surpass US 93.

Personally I prefer Husky 94.
Yep. In Australia we use the RON system for unleaded fuel and works out something like this (roughly as it's not linear).

89AKI = 93RON
91AKI = 95RON
93AKI = 98RON

We have variations of the 98RON, often labeled as premium, and some containing up to 10% ethanol, which makes it tricky to accurately calculate ethanol content without using a flex sensor. Even the E85 here is labeled as 107RON, and is known to fluctuate in content from around 70-85%, depending on batch and where it's sourced.

Sweet Australia! Atleast you guys have e85! I have to buy 205 L barrels of e98 if I wanted ethanol.

Yeah I've had the best experience with husky 94 (e10), it behaves like a true 94. Plus it's consistent all year round, no winter blend fuel that feels like 91.

What's winter?

Yeah we had 100RON available for a while here, which is probably pretty close to your 94 - it was great but couldn't sell enough of it to justify using another pump slot.

Back on topic - anyone know what the factory in-tank LPFP puts out (GPH/LPH or PSI)?
Trying to figure out how to interpret the JB4 log for the S63 FP_L value, as during WOT it ranges from 107-149.

Yes, our Stage 4 kits utilize a 6um 200GPH E85 compatible fuel filter.

Factory on E and F series is approximately 60-75psi and at .6 to .8GPM. On JB4 logs, multiply the FP L value by 10.

Thanks Steve - so based on my FP_L values in the logs ranging from 107-155 during WOT, averaging around 130, I could assume to halve this (53.5-74.5) to get a PSI, rather than using the N54/55 method you mentioned.

Those values are not correct. This must be an N55?

No - it's S63 4.4L TT Petrol.

If you have a look at all the individual X5M JB4 logs posted, these FP_L & FP_H values are about the same across all the vehicles, varying only slightly due to increased TRIMS etc.

EDIT: I asked you about this in my first log thread, first post > http://n54tech.com/forums/showthread.php?t=45087

On a tuned FBO N54, will the bucketless LPFP make any difference in performance using 91 octane pump gas here in California? I believe the gas is E10 where I fill up. Or is it really only beneficial for those who are running higher mixes of ethanol?

No, octane is your biggest limitation and unless you are running a really big turbo or have a weak LPFP, it won't make a difference.

I appreciate the reply. It sounds like high concentrations of ethanol is the only reason for the upgraded flow characteristics of the LPFP upgrade since the engine requires a higher volume of fuel when running ethanol. Is this right?

Thank you

Depends on the actual power level of the car. Cars running upgraded turbos on pump or race gas also need an upgraded LPFP.
