15 data comparison of Porsche Cayenne 3.0T before and after upgrade-
Original factory: horsepower 333Ps? Torque 440Nm；;
First order: horsepower 403Ps? The torque is 540Nm.
The first order 0 1 measured 5.97 seconds!
15 the Porsche cayenne is equipped with a 3.0T turbocharged engine with a maximum power of 245kW(333Ps)/5500-6500rpm and a maximum torque of 440Nm/3000-5250rpm. Official 0- 100km/h acceleration 6.9s, 8-speed automatic manual transmission. After all, it is nearly two and a half tons, and it is hard to avoid being light enough to start. The owner also hopes to make the power go further!
Say the important things three times. Before starting today's story, let's ask and answer the following questions.
1, warranty problem. At present, most of the first-order hardware hardly moves, and it is impossible to detect whether the ECU has been brushed without special detection equipment, so there is generally no need to worry too much about the quality assurance problem. And we also provide two-year ECU warranty, while 4S only has three years! (If you need to overhaul, you need to take the warranty. At this time, you must first recover and then protect. )
2, the so-called 100-kilometer calculation (AMG is only 4.9 seconds). Affected by specific environment, oil products, drivers and other factors, it is difficult to ensure that every car can play well.
3, horsepower machine. The program of each of our cars has been tested with a horsepower machine, which is really gold. It won't cheat customers by cheating like some unscrupulous merchants. Customers who are not at ease can come to us for testing (of course, a small fee is required).
4. Fuel consumption. By optimizing parameters and setting the best ignition time, the first-order program can make gasoline burn more fully and save fuel in theory. The real decision on fuel consumption is at your feet.
5, the life of the engine. As for engine life, brushing a first-order program will have an impact (very small), which is far less important than not maintaining it in time. The engine will leave a certain margin when it leaves the factory, and we only release that part.
6. Example: Why should we upgrade 730 instead of buying 740? Most car owners want to save money. You should know that you can get the same power as 740 by brushing ECU, and the price is not high. Why not?
Let's start the upgrade process. First of all, according to the agreement and past experience, the car can run in OBD direct reading mode. The protocol is Simos8.5 (same as A8). Successfully read out the original factory program, and package the program, nameplate and vehicle condition log information and send it to Shanghai headquarters.
After a preliminary review, the technical director of Shanghai headquarters and German technicians jointly determined the adjustment plan. According to the environment, oil, atmospheric pressure and vehicle condition, more than 3000 parameters such as ignition angle, ignition pulse width and intake pressure are re-optimized.
The adjustment time may be different according to the actual situation. After about two hours, the program will return and write to the original car.
Drive test analysis log to ensure the stability of the program! Followed by repeated road test, 0 1 test, and get on the horsepower machine if possible. If not, recalibrate until the customer is satisfied. (This is also the charm of the special tune. During driving, information such as vehicle pressure and ignition angle can be seen at a glance. )
Finally, the owner test drive: speed release. In the past, the speed could only reach 3800 rpm, but now it is more than 5000 rpm. There is no charge for breaking the speed, and the customer is quite happy. Partial ignition is still very satisfactory. The customer said that there was air leakage in the middle section of CSK exhaust, and the sound leaked slightly. Strong start, obviously light throttle, carefree driving experience and perfect charming voice!
