Well deserved @Biju Abdul !! -
During desert driving, the aim of an offroad club safety flag is to improve visibility in the dunes, so that other members, or even another convoy can spot you from far away. This is an essential safety item that every offroader should have. We like to define a "proper" offroad flag below: Minimum height: 7-10ft (2-3m) above your car height (roof). Should be mounted vertically, preferably on roof or on side window. Should be sturdy and fixed properly to be visible throughout the drive. Allowed Flag Types: Any solid color flag Sports team flag Social cause flag YOUR FLAG SHOULD NOT RIDICULE OR MISUSE OUR OFF-ROAD CLUB Not Allowed Flag Types Torn cloth, towel, safety jacket, plastic bags are strictly not allowed. Political or religious affiliations flag. Any other off-road club flag. Any brand promotion flag. Offensive text or logo. Now that your car is safely equipped with an off-road flag, make sure your driving skills are just as ready. If you are a new 4x4 owner and wish to learn offroading with your stock 4x4, you should start with personalized 1-on-1 desert driving training with certified instructors. No modifications, gears, or experience required. You can also learn all possible desert self-recovery techniques in one comprehensive 1-on-1 course. Perfect for beginner to advance level off-roader to be fully ready with the right skills, knowledge and techniques while off-roading. Or you can unleash the full potential of your 4X4 vehicle and experience the thrill of conquering the dunes with our Advance Desert Driving Course.

Pajero tuning and custom headers
Frederic replied to Jordan Cope's topic in Mitsubishi Pajero Forum in UAE
Well, let's say the original 3.5 engine has 177hp as per Mitsubishi. They haved tuned this engine with enough safety margin to keep the engine performing well in extreme terrain, high temperatures, abuse, and sufficient lifetime (250k plus). Going for a chip-tune changes the original tune, and will bring the engine probably to around 200hp or a bit more. This means your safety margins are becoming smaller, and your engine will have to work a bit harder. Don't get me wrong the Mitsubishi engines are if well maintained extremely reliable, and can mostprobably take the 200hp but this will also depend if you are pushing the car every day towards that limit, or only occasionally. The reason i would not recommend chiptuning on a 160k engine is that your engine will have some wear and tear already and the chiptuning MIGHT accelerate the wear even faster. But this is not proven of course and is just my personal opinion. 275 tyres are quite big. Going back to 265 tyres with a not-too-agressive thread profile will definitely help for climbing. If your BMC filter is a cone-type sport air filter, it will suck in the hot air from the engine bay and will even get you less power than the original OEM filter. I decided to keep my original air filter setup and tried with K&N drop-in filter but eventually went back to a full-stock OEM filter. Changing the headers should be looked at by a professional. Based on their length either the top-end horsepower or low-end horsepower will be affected. PS the 3.5 Pajero lacks a bit in top-end horsepower, but has excellent torque. Going the tuning route or selling the car and going for a 3.8 is worth thinking of what suits you best. It could be that the second option will end up being cheaper. -
Pajero tuning and custom headers
Frederic replied to Jordan Cope's topic in Mitsubishi Pajero Forum in UAE
Hi Jordan, Engine tuning in the form of chiptuning will indeed bring more power, but personally i would not recommend it if your car has done more than 100k already. Unless the engine has been rebuilt of course. The 3.5 is indeed borderline underpowered, but with a SWB they are luckily not that very heavy. When you want that bit of extra power, where do you feel you are lacking power currently ? - Climbing big dunes. - Overall desert driving / dune bashing. - On the road. Be aware that big and heavy tyres rob you from a lot of power. I would recommend to get the vehicle thoroughly inspected first (injectors, spark plugs, clean air filter), and then take it from there. I've seen many cars underperforming in the desert but when i asked them when they got their spark plugs or injectors serviced the answer was "never.... i only change my oil".. A cold air intake in combination with a less restrictive exhaust will help a bit too once you have verified if the engine, injectors, plugs etc.. are in optimal condition. -
DRIVE RSVP IS NOW CLOSED Please find your convoy numbering for tomorrow posted below: Some pointers: 1) Please be aware of our COVID rules and follow them strictly. Drivers and passengers coming out of the vehicle during inflation/deflation should wear a mask at all times. We are not allowed to socialize so we need to stay inside the vehicle during the drive. 2) Please make sure to bring your Newbie gears: A programmed radio, flag, shovel, pressure gauge and deflator. We will not be providing spare radios and will reject you from joining the drive if you do not have these items with you. Having said that, we are having a strong convoy and excellent support. @Pancho will be our centre forward and your first help in need if there is an issue in the front of the convoy. @Foxtrot Oscar (Angela) will be sweeping our convoy and will be assisting with recoveries as well at the end of the convoy. (who ever is closest will come and assist). Our plan is to hit all the play areas and make our way to Fossil Rock. This area is rich with vegetation and beautiful sights. If any of you cannot make it, please inform us on the drive topic so we can try to add someone from the waiting list. See you guys tomorrow !

Latest Update: As of now the drive RSVP signup is still full. However as i have noticed that @Archibald Jurdi was not able yet to signup for one single drive on the weekend, i will add him to the drive to get him to have at least one Carnity drive. Please confirm if you can make it Archibald, otherwise the spot will be given to @Ahab Shamaa

We can distinguish 3 different controls on most modern 4x4 cars: 1) ABS (Anti-Lock braking system) A standard Anti-lock Braking System uses four wheel speed sensors, a hydraulic pump, hydraulic valves, and a controller. The controller in the ABS system monitors the speed of each wheel using the wheel speed sensors, which are usually hall effect sensors. If the controller sees that one wheel is decelerating at a rate that couldn't possibly correspond to the vehicle's rate of deceleration, it actuates the hydraulic valve in that wheel's brake line to reduce the brake pressure applied to that wheel. This allows the wheel to turn faster. Once the wheel is back up to speed, it uses the pump to introduce the pressure back into that brake line, applying that brake again. When the controller sees rapid deceleration again, it activates the valve and the cycle repeats about 15 times per second. The ABS system is mainly made to avoid your brakes from locking up during hard braking, which would cause your vehicle to start slipping. 2) ESC (Electronic Stability Control) Electronic stability control (ESC) is a computerized control system that applies brakes to individual wheels and reduces engine power to ensure that drivers maintain control of their vehicles. The six main components of an ESC system are: wheel speed sensors, a control module, a steering angle sensor, a yaw rate sensor, an accelerometer, and the hydraulic modulator. Note that the hydraulic modulator is the same one used in an ABS system, meaning that ESC adds only the yaw sensor, an accelerometer, and steering angle sensor to a standard ABS system. To understand how this system works, imagine you are driving down the highway at 60 miles per hour. You swerve left to avoid hitting a raccoon. What happens in the short duration to follow? The yaw rate sensor determines where your car is pointing, the steering angle sensor determines where your front wheels are pointing, the accelerometer determines if your vehicle is sliding, and the wheel speed sensors monitor each wheel’s speed. If you turn your wheel very abruptly to the left, your vehicle will initially under steer. This is simply Newton’s First Law. Since the front tires do not yet have enough traction, they slide and the car continues to move forward. The control module recognizes the discrepancy between the intended path (communicated by the steering angle sensor) and the actual path (communicated via the yaw rate sensor) and sends a signal to the hydraulic unit, directing it to increase braking power to the left rear wheel. This causes the automobile to rotate left (the desired response). If necessary, the control module will also reduce engine power by sending a signal to the throttle actuator asking it to close the butterfly valve. 3) Traction Control Traction control works in a similar way as ESC. If a vehicle is unable to gain traction in icy conditions, one wheel will spin while the other simply remains stationary. This is the nature of an open differential: the wheel with the least traction receives the most power. This is undesirable in low-traction situations. As such, traction control can step in. Traction control monitors wheel speed using ABS wheel speed sensors. If a wheel is slipping, traction control reduces engine power to help the wheel regain traction. If necessary, traction control can also apply the brakes to the slipping wheel. This will transfer power to the other wheel (which now has more "traction") depending on surface conditions. As you can see above, these electronic aids are functioning together, all with the same aim of increasing safety for you and your passengers. During dynmamic offroading in sand, the speed and yaw sensors will assume that you are losing traction, and the system will start to react with reducing engine power and diverting power to the wheels that still have traction. That is the main reason we disable these systems.

LED Light bar questions

LED Light bar questions
Frederic replied to Christian Andras's topic in Toyota FJ Cruiser Forum in UAE
I have two of these sideshooters on my front bumpers and they really help a lot when aimed at the corners. Dragon Mart has them from Toby's brand. -
LED Light bar questions
Frederic replied to Christian Andras's topic in Toyota FJ Cruiser Forum in UAE
Hi @Christian Andras your points and concerns are completely valid. I used to have a double led bar mounted on the roof, but the wind noise was quite horrible and the reflection on the hood was also there but by pointing them a little bit upwards i was able to minimize that. From my opinion i have seen better results from a slightly smaller bar with latest LED technology mounted on the front grille. -
