Test drive the 2013 Land Rover GM Tech2 Freelander 2

Land Rover Freelander 2 in 2007, officially  GM Tech2  entered the Chinese market, has won a lot of consumers in the market segments from the beginning of it, regardless of the brand or vehicle performance, it is really less at the same level models. Over time, the 2012 Land Rover Freelander 2 "downsizing", originally equipped with 3.2-liter engine is replaced by a 2.0-liter turbocharged engine. Guangzhou Auto Show in November 2012, Land Rover Freelander 2 again the upgrade, before the upgrade is no longer the power system of the vehicle, but the exterior and interior details improvements, through subtle changes allowed to become more powerful.
For the appearance of the Freelander 2 prevail into China so far, it did not happen much has changed, even in the "downsizing" of its engine in 2012, Land Rover has not the appearance of the Freelander 2 adjusted. However, with consumers vehicle appearance needs to improve and certain provisions of the law, Land Rover in the body of the car the 2013 Freelander 2 cut a scalpel, it is the appearance of some of the details have been adjusted.
The reason why the above with   Gm tech2 scan tool   cut the scalpel these words, the most important reason is the the biggest change in the appearance of the 2013 Freelander 2 is in its headlights parts, parts for vehicles equivalent to the human eye I will naturally spend such words. February last year, my colleague to Lijiang test drive the 2012 Freelander 2, the 2013 Freelander 2 headlights in the shape of the contours of the headlights still intact, but in terms of the construction of the light group there is a very significant changes. Smart lights with new Freelander 2 fashion sense to some extent, and between a mandatory requirement of European law on the vehicle daytime running lights, new Freelander 2 with lights and in front of lanterns together form the 2013 Freelander 2 daytime running lights, which in 2012 models not equipped with.
In addition to this change, the 2013 Freelander 2 front face there is a significant change is add more chrome trim, whether it is at the air intake grille or fog lights, a large area with a chrome-plated decoration, which makes   gm tech2 Candi    the front face of the 2013 Freelander 2 has a more modern and scientific and technological sense.

GM Tech2 brake failure causes and response

Caused by brake failure for many reasons, one is the lack of necessary  GM Tech2  maintenance, too many impurities in the brake master cylinder brake system, Mifengbuyan vacuum booster pump failure, brake fluid is too dirty or several brake oil mixed use heated air resistance brake master cylinder or wheel cylinder oil spill, leak gas tank or piping interface; cause mechanical failure due to improper operation, such as a long downhill causes the brake pad friction and heat, the brake hub charring, brake function completely failure; seriously overloaded, the role of the acceleration of gravity, increased vehicle movement inertia, a direct result of brake failure.
If the vehicle is in motion brake failure, the novice should be how to do it?
1. According to the road conditions and vehicle speed control direction, disengagement high gear, while H kick empty oil quickly, the high-speed gear shift into low gear. In this way, the engine will be a lot of resistance to traction speed decreased rapidly. In addition, while the downshift, should be read in conjunction with use of the handbrake, but note that the handbrake can not taut hold, we can not pull too slowly. If you pull too if pulled too tight, easy to make the brake disc "locking" is likely to damage the mechanical transmission loss of braking ability; cause the brake disc wear ablation lose their braking effect.
2. Natural use of car bumpers, car parts such as rigidity and roadside obstacles (rocks, trees or slope) friction, collision, to achieve the  Gm tech2 scan tool   purpose of the force parking out of danger as much as possible to reduce the losses caused by the accident.
3. Uphill brake failure, should be timely reduction credits in low gear to maintain sufficient momentum to drive onto the top of the hill parking. For the Banpo parking, should keep a low forward gear, tighten the hand brake, the attendant promptly with stones, Stow things stuck wheel. If after the slip phenomenon, should be directed to the hillside or safety rear side, and turn on the headlights and emergency lights, the attention of the front and rear of vehicles.
4. The downhill brake failure, can not use the vehicle itself to control the speed, the driver should be bold and use of natural obstacles, such as roadside rocks, trees, etc., cause resistance to the car. If you can not find a suitable terrain, objects to the use of emergency on one side of the body to move closer to the hillside to increase the   gm tech2 Candi   resistance to friction, gradually reduce the speed.
5. The vehicle next long slope, steep, regardless of whether the case should step on the brakes. Either test braking performance, can also control the speed to win the time found the brake failure, also known as predictable brake.

Talking about GM Tech2 wheels data

Upgrade the hub is the first step of many to pursue  GM Tech2  personalized owners to create their own unique car, but in the face of numerous, but a wide variety of all kinds of wheels made a difficult, do not know where to start. In fact, as long as the little secret learned wheels behind, overwhelmed troubled swept away.
Rim diameter:
Popular talk is the wheel diameter, in inches. Between players playing rim converted pursue "big is beautiful" aesthetic philosophy, the large size of the wheels to bring a richer visual impact of the effect, while improving the overall texture of the vehicle. Aesthetics, the hub of the larger size also has a more practical role, not only can be installed flat tire than the lower improve vehicle handling, the brake system is able to accommodate the larger size to meet the higher braking demand . However, special attention is accompanied by large-size wheels usually comes greater quality.
Tire diameter and width:
The hub of the width of the rim, which represents the width of the hub unit of the same are in inches. Different tire diameter wide wheels need the corresponding install different width of the tire, such as 8 "to 225mm ~ 245mm tire width tires installed on the most appropriate.
Behind the tire diameter wide  Gm tech2 scan tool digital usually J, JJ English letters, which means that the shape and height of the hub flange, in addition to J, JJ, the height difference according to the hub flange, there JK, C, K, etc., C minimum, K is the highest. However, simple upgrade wheels, hub flange factors not require deliberate attention.
Offset:
That offset, also known as the ET value. Refers to the offset distance of the centerline of the mounting surface and the hub of the hub unit mm MM. Offset is divided into negative offset, offset 0, is offset three kinds, based on the distance of the hub-mounting surface and hub centerline to the outside direction as positive offset negative offset to the wheels inside of when The hub mounting surface with the centerline of the wheel hub coincidence, the offset is 0.
The hub offset distance is smaller, the larger the vehicle tread, but in the hub of the tire diameter width unchanged under the premise, a hub offset the smaller, the inside of the hub to accommodate the space of the braking system will be compressed accordingly smaller, this when you want to install the large size   Autel MaxiDAS DS708 of the brake system may be affected. In addition, inappropriate hub offset distance may also cause the hub tire and vehicle suspension systems, the fender movement interference occurs, is too large, the tread of the bearing load increase, the wheel alignment data anomalies and other adverse consequences.

Chassis contrast of old and new Audi A6L GM Tech2

A bottom view from the front of the chassis between the GM Tech2  generations Vchicles comparison chart, you can see that both the existing differences, the most obvious is the composition of the lower control arm, tie rod by the steering of the machine down, also involved in the suspension lower complete their work on the control, this arrangement also helps to enhance the stability of the wheel. In the upper control arm part, the biggest change is on the control arm bracket directly integrated in the die-casting on the top of the tower, and the old models A6L out a separate bracket. Light weight, number of parts, and compact structure extent, no doubt, the new model is dominant. And the new A6L use die-cast aluminum top of the tower is lightweight purpose of the steel parts of the older models meet the strength requirements.

 Change the hydraulic steering system from the original mechanical drive to the motor drive, As for its benefits will not introduce more, most worth mentioning here is turning the machine on the installation location, in the previous models, Steering arranged in the top of the gearbox, or rather should be inside the firewall, steering rod is pulled moving wheel bearing (commonly known as: croissants) top to achieve the rotation of the wheel. The seventh generation of Audi A6L will shift down, based on the changes in the Gm tech2 scan tool   position of the steering machine installation, the entire front suspension to be moved forward, which is obviously taking into account the vehicle's handling performance. In this regard, A6 but walk in front of A8 "dragged" by W12 engine top A8 models equipped with a W12 engine is still used with the the mechanical hydraulic power steering system with steering function, no installation location changes. Auto show in Beijing, we also issue an interview with the German engineer in charge of the business, he said, in the future, the electronic penetration will become increasingly high.
Dynamic steering system is also fitted on top with models of the Audi A6L, motorists will be able to adjust the sensitivity of the steering wheel through the MMI system to obtain or exercise or comfortable driving experience, of course, there will naturally include electronic booster pump to the steering wheel to provide feedback efforts. Audi dynamic steering system structure with BMW and Toyota's system is essentially different from its core components are the core of the electronic control system of a harmonic gear drive mechanism. The so-called "harmonic gear flexspline rigid wheel and the relative movement of the wave generator, in particular controllable elastic deformation (shape change) of the flexspline to achieve movement and momentum transfer.

 Compared to the other brands to rely on the planetary gear set to achieve dynamic steering, the harmonic gear used by the Audi   gm tech2 Candi  dynamic steering system is a set of structures are widely used in other areas, and it is characterized by simple structure, high load carrying capacity, large transmission ratio; In addition, under the premise of a smooth operation, and its noise suppression is very good.

BMW GT1 audio conversion Contraindications and Precautions

According to statistics, the general converted  BMW GT1  audio cost about 1000 to 7000 per month. So in talking about the modified car stereo, many car group admits that she is not a quasi-professional level audiophile therefore only want to draw a little money to improve the musical environment and musical sense of music on it. So often the choice of car modification shop "for what is cheap what to choose, the price for" the truth forgot it, leading to the eventual modification effect is not satisfied.

Car audio conversion Contraindications and Precautions

Audio conversion is estimated to note first professional error on selected car modification shop circuit problem, modification and repair of car audio must be to have professional experience in the modified car shop, because professional conversion shop is likely to destroy the original car circuit in the conversion process, it will not only  BMW GT1 DIS V57 SSS V41   sound did not improve, may affect the vehicle warranty and after-sales service. Therefore, the wiring, be sure to do a separate cloth power cord, audio cable, signal lines, and the line between good shielding and protection, is foolproof. For car owners, however, is difficult to correctly judge whether a car modification shop professional. The best way to advance the view around the car modification shop recommended assessment, do know the answer to eliminating the need for unnecessary trouble.

Ignore car converted upgrade space   GM Tech2   It is understood that many owners in the modified car audio, often overlooked room for future upgrades. The converted audio generally has a step-by-step process roughly the order is the first for the speaker, and then upgrade the effectiveness of additional woofer, and finally replace the host. Owners who are best able to reserve some space for the upgrade To upgrade to parse strong host in the future, will be able to reach a hifi sound effects. If you do not forecast a future upgrade space, will encounter the upgrade until the time of the upgrade demand bottleneck.

When people judge a professional   Gm tech2 scan tool  ound good and the bad sound system, regardless of the frequency response as the main objective of the evaluation curve smoothness.
