Looking for ways to make your engine more powerful, installing an car engine performance chip is often a quick and easy way to get a lot of power. The truth behind these chips can be based on the installed car, any existing modifications, and how the chip is tuned. The reality is that even the most complex ECU chip tuning can not increase power output without modifying other systems in the car. This means ECU chip tuning are available, drivable horsepower, if you are right. Regardless of these factors, you should know something in advance before installing the chip in a car.
Chips Don't Always Make Safe Power:
While power gains can be found in almost any engine by advancing the timing, this isn't always the safest way to go about tuning. While advancing timing may give you some horsepower, it can often times radically increase an engine's risk of detonation and potential failure. Sometimes reliability is more important than single digit power gains.
One of the most important functions that yourcar ECU fulfills is regulation of the emissions functions on the car. Sometimes an “engine chip” will disable these systems, which can result in a failed emissions test as well as the “check engine” light coming on. Any chip which deactivates your vehicle's stock emissions controls isn't doing your car any good and is probably illegal.
Advertised Gains Don't Often Match Reality
Many chip tuning companies advertise great power gains with dynamometer-proven results. What most of these companies won't tell you is that the specific conditions and modifications present for these gains may require extensive changes to your engine to reproduce. Tuning is merely part of the puzzle.
There are relatively simple tricks that an engine chip can pull to increase power, primarily during “wide open throttle” during high RPM conditions. The sacrifice is normally a LOSS of power under other conditions, usually having adverse effects on drivability. This means that you are sacrificing overall performance for slightly increased power output during a specific fraction of the time, and it definitely will not make your car faster.
There Is No Such Thing as A Universal Chip
Proper tuning for safe and substantial power gains is best done on an engine per engine basis on a dynamometer by an experienced professional. While a specific tuning setup may work great on one engine in a particular configuration, even the slightest change to climate, weather or differences in modifications to your engine may cause problems.
Chips Will Almost Always Void Your Warranty
As a general rule, opening the ECU will immediately void the warranty. Chip installation changes a variety of variables vital to engine operation such as fuel values, ignition timing, knock correction and even fuels cut and redline data. These changes can remove many of the safeguards the manufacturer uses to protect the engine and because of this they almost always end up voiding your warranty should engine damage occur.
Installing A Chip Generally Requires Premium Fuel
Regardless of chip used, power gains are found by altering fuel maps and ignition tables. These changes remove much of the safety and flexibility found in a stock car, and because of this, premium grade fuel and sometimes even an octane booster is generally required for safe operation. Keep in mind these additional expenses when purchasing a car performance chip.
Also, engine chip modifications can have negative effects on a vehicle's gas mileage, especially any chip that alters the emissions control systems of the vehicle in any way. This lost efficiency can be costly, and probably isn't profiting you anything in terms of horsepower.
Modern ECU's Are Clever
Depending on the type of chip used, the method of tuning employed, as well as the car it is installed in, it is possible for the ECU to relearn its old tune. Modern ECU's are becoming more adaptive and as a result, specific tunes may only be temporary as the ECU can sometimes relearn old tunes in a matter of days or weeks, requiring reboots and clearing of the memory on a regular basis.
While chips can provide noticeable power gains, they are rarely without tradeoffs. These gains can increase the cost of operation and require changes in useable fuel as well as aftermarket octane boosters. Understanding these costs going in, as well the gains you can expect to see and your experience will be far smoother and enjoyable.

Today, We Received a iPhone 6 plus motherboard from one of our customers, according to his description, the weak WiFi signal is the main problem. How to fix it with the best solution? Picture 10-4-1
Step 1. Install the iPhone 6P motherboard to test WiFi signal. Obviously, It's weaker than a normal mobile phone. Picture 10-4-2
Step 2. Remove the motherboard to check, the WiFi connector circuit is not damaged, in many cases, most of repairmen would directly replace the iPhone WiFi IC if WiFi itself gets damaged.
Step 3. Since we have advanced equipment with VGA 7-45X Trinocular Stereo Microscope to do careful observation, the motherboard is very beautiful, there is no water damage trace, the first consideration of fault is pressed parts.
Step 4. Indeed, we can see the IC be pressed under the microscope , of course, do not first think that WiFi itself under pressure, sometimes the next filter will also suffer pressure. The following picture 10-4-1 is pressed IC fl_cell_rf with false welding, also with minor cracks. picture 10-4-3
Step 5. Take care to remove the IC and the small inductance. Losing inductance will also cause weak WiFi signal, of course, it is also possible to solder jumper wire to solve this kind of situation.
Step 6. Reinstalling IC fl_cell_rf to test WiFi signal, the problem is successfully solved now!

What would you do if you were watching a favorite TV show, playing games, shopping and suddenly showing that there was no Internet? I'm sure you're going to feel angry and sad. Now you must want to solve this problem quickly, Therefore, today we discuss in detail the free solution to iPhone 6 WIFI cannot be used.
First, get into IOS to test it, the Wi-Fi MAC address can be found in “about iPhone", just the WIFI button is greyed out.
Second, disassemble the iPhone by phone opening tools, then use Fluke 15B+ Digital Multimeter to measure the diode date iPhone Wi-Fi IC and PCIE bus. In this part, we need to know the test point of PCIE bus is on the coupling capacitance that is on the right of U1501. We directly measure the ends of the capacitor, the normal diode data is about 350 on one end and 500 on the other end.
Third, after measuring, the diode data of these 6 capacitors all is normal. Now we directly remove the iPhone WIFI IC, and then measure the diode data of each pin of solder pad, all is normal. We decided replace the new WIFI chip to test it. After replacing, the problem still exists. In this time, we can judge that it is caused by unqualified Wi-Fi working condition.
Fourth, open the WUXINJI Dongle to check the iPhone circuit diagram, we found that we forgot to measure the voltage of WIFI clock. Remove the WIFI and test the clock, there is not 0.9V voltage. The frequency of the Wi-Fi clock is 32.768kHz, which is made by the Y1200 crystal oscillator. Then Y1200 crystal oscillator transmits it to power chip. Power chip transmits it to Wi-Fi chip. Considering the iPhone is dropped, the crystal oscillator may be broken because it is not anti-shock. Directly replace the new Y1200 crystal oscillator.
Finally, after replacing the new Y1200 crystal oscillator, assemble the iPhone and turn it on to test, now the WIFI button is back it normal, and it can be turned on smoothly. The WIFI signal also normal, you can use the WIFI again!
Tips: The iphone Wi-Fi chip cannot be removed when the diode data of PCIE bus is being tested. Otherwise, the diode data to Wi-Fi can be infinite. The circuits between Wi-Fi solder pad and the 6 capacitances often disconnect. So we can directly measure the ends of the capacitor.
The iPhone 6 is able to boot and receive calls, but the screen does not display, we replaced the screen before opening it. It doesn't look much damage on the appearance, after replacing a new iPhone 6 Plus screen to test, it still doesn't display and no backlight.
The measurement of display conncetion resistance is shown in picture 11-2-1.
The measured value is completely normal, there is no current burnt traces on the iPhone backlight chip and display power supply IC, so we can start to work on its display part. Taking off the display IC under good protection, and work on solder pad with low temperature solder, do not rush to replace the new IC, the bottom resistance should be measured before that. As shown in picture 11-2-2.
The result shows that the D3 pin I2C bus CPU has no resistance to the clock signal of the display power, and the C3 display has no resistance to the power IC signal. According to these two results, we can make sure that the lock screw is wrongly installed to cause the motherboard layer being broken. Open the 6P bottom screws column diagram,we find that C3 go through left and right sides of the screw column, D3 only go through the left, After removing the 2 screw columns, we find both of them get traces of damage (you can remove the screw columns with solder paste, hot air gun with 300 degrees and gently push then down by solder iron, we find there is serious disconnection on the left. As shown in picture 11-2-3.
First, scraping a waste main board without broken wire and observe the wire construction. Select a smaller phone fix scraper tool, gentlely scrape and try not to damage the bottom wire since there are several layers in the iPhone 6 plus motherboard. you need to pay attention if there is black layer shown up for sraping the first layer, then you can add a bit of soldering paste on it, it will be clear to see the specific location of the wire under a microscope.
As shown in picture 11-2-4, we choose a similar sharp knife to throw off the location of the broken wire and find the thread. The left screw can find a resistance thread. We choose a sharp iron with professional jumpers to solder every wire carefully and try not to repair it next time.
We can solder the jumper under the microscope, as shown in picture 11-2-5, the screw column on both sides of the line have in common, the left one can not find the thread so we can use the right column to make jumpers, then we measure IC bottom pin resistance again. The resistance is normal, now solidifying with green oil and install display power supply to test.
Finally, the screen light and display normally again, functions are tested perfectly.
