WELCOME TO THE SCORPION BUILD-UP THREAD​

The sword is more important than the shield and skill is more important than either.

All men dream, but not equally. Those who dream by night in the dusty recesses of their minds, wake in the day to find that it was vanity: but the dreamers of the day are dangerous men, for they may act on their dreams with open eyes, to make them possible.
--Lieutenant-Colonel Thomas Edward Lawrence, CB, DSO

The Scorpion FJ, though unworthy of the man, has been created in honor of T. E. Lawrence (1888-1935), may he rest in peace.



When I bought the FJ, I mapped out a philosophy on which direction a build-up should take. My philosophy was built around a vehicle that could operate, removed from populated areas, and support my interest in exploration and examination of unsettled regions (increasingly difficult to find). Sometimes the questions are complicated and the answers are simple.

My philosophy in modifications is simple. I wanted to create a strong, capable, sustainable rig that would BRING ME HOME at the end of the day. Everything I've done to my FJ has that particular end in mind.

My favorite FJ Cruiser Moment: I'm driving my FJ on an expedition and I can't fall asleep at night under the stars because reality is finally better than my dreams.


This is the stock FJ.

I bought my FJ Cruiser on December 23, 2006 as a Christmas present to myself since it was highly unlikely that anyone else would buy an FJ for me no matter how hard I tried to get off the naughty list.


My daughter Emilie agreed to ride shotgun with me on trail runs.

concentrated mist,

a clear jewel on a leafpoint,

drip,

the river begins!​

EXPEDITIONS

When selecting team members everyone looks for a combination of factors in their team mates. The most important is an absolute passion for the project, an ability to communicate, a diversity of proven expedition-specific skills in remote and hostile environments, physical stamina and mental toughness. FJ Cruiser expeditions are designed first and foremost to be fun. Secondly, they hone your skill sets by forcing you into new and unfamiliar situations that requires you to adapt and overcome. Thirdly, you get to make the run in a Toyota FJ Cruiser.

JASON DeMELLO SAVED MY A$$ (again)

On the eve of my North Rim - Grand Canyon/Aztec Caves run with VOLHOO, I started the engine of the FJ.

<CHECK ENGINE> light on

When the check engine light goes on, all of the traction control lights come on and it's quite spectacular.

No problem. I have a ScanGauge2. Yes there are error codes, but none correspond to Toyota error codes.

The rig is driving fine. I run down to Auto Zone and plug in their scanner and it shows the following error codes: P043E, P2401, P2402, P2419. They looked them up for me. They only correspond to Mazda and Volkswagens.

The clerk at Auto Zone picked his nose, rubbed his hand through his hair (I'm not kidding - literally) and told me he had "no idea".

So I drove to ToyotaMasters and spoke with my friend, Eric, who broke out his scanner. All it showed was "error".

W-T-F over?

I hate to bother Jason DeMello, but he's THE genius so I drove to his shop. The diagnosis took all of about three seconds.

MAF Sensor



For those of you who are knowingly saying "of course that's what it is", keep in mind that I am a functional idiot - relying on gauges and diagnostics to cover my ignorance.

The MAF Sensor plugs in behind the OEM Secondary air filter. Oil from the K & N air filter I was running slowly accreted on the sensor over time. Dust attached itself to the sensor (with a minute quantity of oil on it).

So I dumped the K & N filter in the trash (if anyone wants it, it's in Jason's trash - they have a lifetime guarantee - rush over before they empty the trash tonight) and bought an OEM filter - and will be going with paper filters now. Jason took his air hose and blew out the secondary air filter and was COMPLETELY helpful.

Apparently this has been a problem with Tacomas that ran K & N Filters. Jason said that if the MAF Sensor gets too clogged with dirt, it will shut down the engine and the engine won't restart.

Electronic parts cleaner sprayed liberally on the sensor cleaned it up.

For those of you who run in dust a lot as I do and particularly those who are running a K & N Filter - this is a learning point: Clean your MAF Sensor. Because if it shuts down and you're in the back of beyond you may not know why the engine died and won't restart - and the error codes on your ScanGauge will not reflect the nature of the problem.

Thats good to know Toyota doesn't recognize their own error codes:rofl:

Glad to hear Jason saved the day, I think a beer is in order.




What does MAP stand for?? I know there is a MAF sensor behind the filter, but a MAP??

Good info Uphill!
I run a K&N (which is identical to the TRD) and would like to avoid this in the future. I'm going to check this tonight. Where is the MAF sensor located, so I can make sure it's cleaned off?
Glad to hear everything is still on for the run tomorrow.

See you in the morning - :bigthumb:
Glad Jason got you all fixed up, hes a good man for sure.

K&N's are great for older cars and trucks but I wont run them on new stuff with sensitive electronics.

Larry check out the AEM Dryflow filter. There a reusable filter that doesn't use oil.
If there was enough oil to clog the MAP sensor it might be possible that cleaning out the rest of the throttle body would be good to do when you have time.

The secondary filter has activated charcoal in it and might have absorbed oil too, slowing down airflow (?).. I don't know if it is cheaper to buy a new one or to try soaking it in gasoline (it is made to absorb gas vapors) and then shaking/drying it out thoroughly.
Great info. I'm running a TRD drop in that requires pre oiling. I've always been very careful not to over oil for this reason. If you haven't already posted a pic of that sensor could you please! I'm at work and can't get pictures here so thanks if you did.:bigthumb:

Really easy to find. When looking at the engine the inlet is to your left and on the top of the inlet tube you'll see the harness plugged into the sensor which is held down with two screws.

I think that this is the correct side view

Thank you Jim. So, you just unbolt it and lift it out to clean then? Awesome. I'll do it this weekend.:bigthumb:

It is easier to remove the wire harness plug before taking out the screws.

I use compressed air to help blow excess solvent out of the inner tube of the sensor.

I also take the O-ring off of the body to avoid getting dried out when cleaning the sensor with solvent. I clean the O-ring off and re-lube it with some silicone grease then reinstall to have a good airtight fit.

3 Days in Utah and Arizona:




VOLHOO, MRS VOLHOO and I took a short run to the North Rim of the Grand Canyon and camped at Toroweap. The place is one of the nicest camping spots I have ever encountered. You are right on the rim of the Grand Canyon and it's definitely the road-less-traveled.


We spent two nights at Toroweap and then headed north to the Kanab area. We had hoped to see the Aztec Tunnels, but the area was posted no-trespassing and we didn't violate anybody's trust.

The guy who works behind the BLM counter suggested that we try the Mail Route Road through Elephant Pass, north of the Pink Coral Sand State Park. He looked at our rigs and said, "You might make it. It has a lot of deep sand.



Not really knowing what to expect, we took the trail that led up into the Parunuweap Wilderness Area/Parunuweap Canyon.



The canyon was forged by the East Fork of the Virgin River and it was a spectacular ride with some very serious approach and departure angles that put the location of the MAF auxiliary fuel tank to the test.






It wasn't all technical driving and trail building. The ride was spectacular.





The Scorpion mods all worked the way they were supposed to!

I feel better about not taking the time to stay and find them. We pushed on to the Navajo and Hopi Nations; starkly beautiful but the people don't like anyone else on their land (off-road) so we respected that and contented ourselves with eating fry bread, Navajo tacos, and turquoise shopping.

Sorry we missed you and the Volhoos; catch you another time for sure.

1911, you might not have made it to the caves with us, but we had some great wheeling.

I may post a poll in the tire thread. I'm torn as to which type of tire to put on the Scorpion next.

Any ideas? I have 305 Nitto Terra Grappler A/T's I'm thinking about Nitto Mud Tires. Any experience with them? Too noisy on the road?

Here are some great shots of the Scorpion crossing the stream in the Elephant Pass.

We had a great time, thanks for asking us along Larry...

We must have crossed this steam 20 times


The first crossing was pretty wild – very steep and narrow – we decided to do a little road work first


The Scorpion went first


Very Steep and very narrow


No room for error here


Mister Cool drives right through it


Up the other side

Looks like a great time Larry, wish I was there with you guys, great pics too. :)

It was a bit disconcerting to drag my front ARB across the muddy bottom of the drop off to be able to cross the stream at what could only be euphamistically called a "ford". The tilt-o-meter was off the scale.

VOLHOO insisted that I go first. As a gentleman, how could I have refused?
