Sword Finger F4W Finals! Let's get out as soon as possible! Talk about your car experience.
How time flies! This LinkedIn 03 has been with me for nearly half a year, and I can draw some feelings and conclusions by knowing a partner. It can be said that from the inside out, from the whole to the details, everything is so real and open. I am very pleased, I believe it is becoming more and more real and closer to me and my team partners. Believe me, this LinkedIn 03 and I have become each other's hobbies.
This weekend, FAST4WARD? The 20 19 year-end finals will begin. At this moment, I am calmer and simpler. Except for those goals that can't be reached at this stage, we have worked hard to achieve them. I am very satisfied to be lucky enough to be on the stage of the finals. I just hope it can show itself to the maximum!
If the day before the final exam is directly compared to the day before the college entrance examination, it is not completely accurate. Supposedly, the day before the college entrance examination, students should gradually reduce the amount of review, calm their minds and spend this short "suffering period" as easily as possible. However, as a contestant, I can't do this. After all, playing with cars is a long and fruitful thing. It is normal to prepare for war all the year round and sharpen your guns when you get cold feet. So my team members and I are still in a state of high tension and even more excitement than before. There is no way, we have to do this!
Of course, the reason for this is an episode that occurred a few days ago: after the upgrade procedure, although the vehicle is running normally at top speed, the throttle is obviously tightened when the speed is increased. In fact, we didn't pay much attention to this common phenomenon when playing with cars. Under normal circumstances, if you pull the throttle hard, it is normal to release the throttle, which may be that the throttle return spring becomes hard; If the tension is not very flexible, it may be that the accelerator is stepping in the wrong direction, and only modification can solve it.
But after careful investigation, these conventional mechanical factors have been investigated, and the rest may only be software problems. In order to ensure that there are no accidents during the competition and that everything is as foolproof as possible, we decided to modify the ECU again.
A lot of things have happened. Brother Programmer happened to be away from Shanghai these days, but on a business trip in Beijing, so he had to make preparations again. Last Saturday morning, I took down the original car-mounted computer of Lectra 03, wrapped it in antistatic and shockproof packaging, and entrusted my friend to take it to my brother programmer in Beijing for re-debugging. The soldiers fly very fast. 1on the evening of October 27th110 instilled the latest modified power scheme. My friend drove the highway overnight and sent me the computer. I visited the Beijing-Shanghai Expressway with my friends, traveled all the way by computer, and returned to Shanghai on June 5438+065438+1October 28.
After we finished writing ECU in the fastest time, the horsepower increased by more than 60 horses and the torque increased to nearly 330 Nm! To tell the truth, although I don't have much expectation for the latest Chinese calligraphy, at least I can afford a new 20-inch 3 15 wide tire, which should be more than enough!
Of course, it's no use just thinking, while there is still time, then get on the horsepower machine!
After the car landed, the torque successfully broke through the original factory's 245 Nm. After the test, it was close to 370, and the system issued an alarm! The engine suppressed the output ... I was not disappointed. I know that this is the limit that this Lectra 03 can reach at present, and I won't be unnecessarily reluctant.
It is hard to say that FAST4WARD's achievements every year are step by step growth, fierce competition and cruel elimination rate. The finalists in this year's finals are all from major competitions. It is absolutely impossible to find a soft persimmon to pinch ... I don't care about these factors. After all, I am a specially invited wild card player, and it is very precious to compete with them. Winning or losing doesn't matter. I am more concerned about the improvisation of the car and the influence of the weather on the state of the game.
Drivers who play with their predecessors know that running in a straight line mainly depends on three aspects:? 1, road grip? 2. the grip of the tire? 3. What is the performance of the vehicle itself? From my personal experience, it is very suitable to choose a smooth and clean asphalt road, without sand and excessive soil accumulation, and the ambient temperature is 30 degrees continuously. At this time, the grip provided by the road itself is more suitable. But the final is in 65438+February, and even Shanghai in the Yangtze River Delta is very cold, which is really a big test for a straight line.
As for improving the grip of the tire, it must be a model with good selectivity and suitable for its own vehicle. Have I ever driven an E92 before? M3, with Michelin PS? CUP2 tires, even if you touch rubber by hand, will feel very soft. Once the tire is warm, the tread will stick to the ground like dough. Now, I have equipped this TOYO for Lectra 03? R888, after reaching the normal working temperature, the tread is also very soft and the grip is excellent. But when I choose tires, I will always adhere to the premise that the newer the fetal age, the better. I won't choose tires that have a long production date or have been in stock for many years. No matter how good the rubber material itself is, the rubber itself will age and harden due to long storage time, so the grip will be obviously reduced at this time.
Many people ask me, what kind of car is suitable for a straight-line crash? In fact, there are really no strict restrictions. If you ask me, the original factory horsepower is above 240, not to mention running 0 1, running 04 will do. Of course, you have to change it. If it is a front-drive car, you should also learn to overcome the skidding of the vehicle from a standstill to a gradually high-speed state.
Judging from the horsepower output, my Lectra 03 is definitely not the forerunner of high horsepower at present, but even so, the first 0- 100 meters may still slip, and it will gradually stabilize at the next 100-300 meters, that is, the moment of full firepower. Because the presentation I choose is between the third gear and the fourth gear, which is the key for me to get good grades in the middle and late stage!
If you are a high-power front-wheel drive with more than 400 horsepower, you need to pay attention to the above problems, and it depends on what kind of power attributes are emphasized in the selected scheme.
This weekend, my Lectra 03 will make its second appearance in FAST4WARD, but this is the first time to play in the finals. The prospect is unknown, and I am excited and nervous. Fortunately, all the preparations made me calm, but I really don't want to predict my grades in advance. As long as you can play to the extreme and run out better data than the actual measurement, you will succeed. I am confident and convinced of this. ? See you in the final, everyone!
