    JB4

    I looked at your map 5 file over there and everything looked good. Your peak boost was 21psi whereas mine was 26psi and that's why mine required more fuel (assuming we were both around 25-30% ethanol). 26psi on the stock Raptor turbos is really too much in my opinion and that's why I never went...

    JB4

    I see you posted in the JB4 forum and they'll give you the best feedback for these engines. My experience running the ethanol map and higher boost was the fuel rail pressure has a tendency to drop trying to supply the higher flow rate required with ethanol fuel. That's why a typical ethanol...

    4th Gen expedition 1/4 mile numbers ?!

    I took my '19 Navigator L to the track when newbto get a baseline before the JB4. Stock was 13.7 sec @ 93 mph in the middle of July.

    “Lift gate or lift glass ajar”

    Crouch down and look up into the lights for your rear license plate. There should be two rubber buttons, one on the left and one on the right of the lights. One button is to release the glass only (I think it's the left button), and the other is to release the hatch. My Navigator has...

    “Lift gate or lift glass ajar”

    Just saw your odometer so I assume it's a new issue for you. I would still try turning the two rubber stops clockwise into the hatch evenly to see if that helps. If not, then like I said previously, you might need to adjust the striker or replace a faulty switch.

    “Lift gate or lift glass ajar”

    If the liftgate and hatch are both "closed" but you're still getting the error message, you might have the same issue I did. I would have to push the striker area on the hatch into the vehicle while the hatch was almost closed in order not to get the dashboard warning. Its apparently a sensitive...

    How many owners out there with no major issues?

    2019 Navigator with 12k miles here. No major problems. Vehicle forums are biased with people that either love them or hate them. I've had my share of American, German, and Japanese brands, and no one is clearly better than the others. That's why we still have so many selections today and not...

    Front & rear windshield washer NOT?

    @wakeboarder @Backinblack Did you ever resolve this issue? Mine has done this intermittently for the past year, and of course never does it for the service techs. Plenty of fluid, pump runs but nothing sprays. Must be a stuck valve somewhere. I can run the pump on/off for a minute in the...

    Max Boost PSI

    @FlyBry For what it's worth, the thread below has my boost plots for reference. All stock Raptor engine besides a JB4 piggyback: https://www.n54tech.com/forums/showthread.php?p=676586#post676586

    Expedition Max on Ford Saleen 23" wheels

    That looks really neat! Have you considered spraying the wheels white with that rubber coating that peels off? I like white wheels on some vehicles and think it would look cool on yours.

    18 inch to 22 inch wheel upgrade question

    Well, you could swap your 2015 wheels onto your 2018 assuming it's the same bolt pattern, offset, etc (I'm new to Ford trucks and don't know much about them) and try it out!

    18 inch to 22 inch wheel upgrade question

    @MattG Yup, to each their own. You just have to prioritize what you'd like to have and then live with the tradeoffs accordingly.

    2018 Navigator getting 6th set of Cam Phasers.

    I was at my Lincoln dealer yesterday asking how many they've done, and they said a bunch of 2018s and just a few 2019s.

    18 inch to 22 inch wheel upgrade question

    Can you just go test drive a dealer one with 22s to get an idea before you spend a few grand? Keep in mind potential damper differences between yours and the dealers, as well as air pressure. I just had mine serviced yesterday and they put 42 psi cold whereas I normally run 36 psi cold without...

    Cam Phaser issue scaring me from buying

    If you go on the Raptor forum there is a survey of engine failures (not just inclusive of cam phaser issues). It appears that a third of those folks have had issues. Keep in mind forums usually attract the extreme vehicle lovers/haters so you're just seeing a small sampling of the population. I...

    Trade in Expedition for Navigator?

    @mcb345 One thing I didn't see mentioned is the dealership experience between Lincoln and Ford. Obviously, quality for both vary all across the country, but something to consider based on your location. Also, if my black label Navi needs service, I can have someone drop off a lincoln loaner at...

    E85 tune?

    @LokiWolf That's why I'm surprised you're so quick 0-60. I'm tapped out with the stock fuel pumps running an e30 mix and its the reason why I asked my earlier question what pumps you're running. The jb4 has selectable boost based on fuel octane (including ethanol mixes) and mods. My 0-60 is...

    E85 tune?

    That's impressive @LokiWolf Do you have aftermarket high and low pressure fuel pumps? I sometimes run an effective e25 blend with my JB4 and 26psi boost (Raptor engine in a Navigator), and that's as high as I can go because my fuel rail pressure drops dangerously low (to the point where afrs...

    2018 Navigator getting 6th set of Cam Phasers.

    Due to the oil path circuit, bad chain tensioner gaskets can bleed off oil before it reaches the phasers, thereby increasing wear on the pins, etc. If those tensioner gaskets haven't been replaced, maybe they were wrong from the factory and exacerbating phaser wear. If you're going in for new...

    2018 Navigator getting 6th set of Cam Phasers.

    So, has this "lead mechanic" done the past four sets of phasers? I certainly would go somewhere else. Your failure rate is too statistically high to be faulty parts. Can you take it to a Ford dealer instead of your Lincoln dealer?

    2018 Navigator getting 6th set of Cam Phasers.

    I think I know why the original owner got rid of it! Have you asked to have the previous records pulled?

    Michelin Premier LTX DT vs Defender LTX M/S

    My 20" Defender M/S2's are a 113 load rating. If you're in a hurry for tires, maybe check out the M/S2's in your size.

    Best Abrasive way to remove bug guts from front bumper

    This. Any trip on the highway during summer plasters bug guts all over the front of mine. In the past I've used mildly abrasive cleaning pads, cloths, aggressive chemicals, and a lot of elbow grease on various vehicles. And then had to deal with the aftermath of polishing to remove all the...

    22" wheels to 20", spare too

    The Hankooks have a higher load rating and that design feature probably plays a big role in how stiff they are compared to these lower load-rated Michelins. Also, I've found that Michelin, in particular, seems to be softer rubber than others when brand new, but get harder and noisier quicker...

    Michelin Premier LTX DT vs Defender LTX M/S

    Thank you. The Premier didn't show up in my search because it doesn't look like they make it in the 275/55/20 size I wanted. It looks like a nice tire too though and would have considered it.
