The owner of a Chery Tiggo 7 Pro Max 1.6 (150 hp, 275 Nm) contacted us at IMCHIP. His request was not new to us:
“I press the pedal, and it first hesitates, and then it suddenly revs up when it’s already unnecessary. You also have to time it in advance when overtaking.”
This is not just a subjective feeling; it’s one of the most characteristic features of most Chinese cars. The problem lies in the factory calibration of the electronic control unit.
The engine is throttled from the factory for our market. On the Chinese market, this same engine produces 197 hp. For the Russian market, it is supplied in a version with 150 hp. The difference is significant — 47 hp..
It’s not just the dynamics that suffer. The transmission may cause delays and jerks, which creates the feeling that you don’t have full control over the car..
The owner gets an engine with a power reserve, but without the ability to use it. We return this stock to IMCHIP without risk to the car.
What we proposed and what happened
We have set Stage 1. Result: 186 hp and 301 Nm (+36 hp and +26 Nm).
The firmware has fixed the very "thoughtfulness" of the accelerator pedal. Now the response to the click is instant. There was a clear, predictable dynamics from the start and over the entire acceleration range.
The acceleration time has been reduced — the car gains speed confidently both from a standstill and while in motion, which is especially noticeable when overtaking on the highway. You no longer need to anticipate the right moment for a maneuver; there’s always a reserve of torque under the pedal when you need it.
The transmission has become noticeably more responsive. Delays and jerks are gone.
For those who want more, we offer Stage 1+: 215 hp and 330 Nm. The increase is +65 hp and +55 Nm to the stock output..
The owner himself will tell you more about the firmware than we can. Be sure to watch the video with the first impressions — they turned out to be very vivid: https://t.me/imchip_tuning/33/2935.
In this case, the customer didn’t notice any changes in fuel consumption; everything will be individual. Let’s clarify right away that the firmware doesn’t directly affect increased fuel consumption. We point out that fuel consumption may decrease because you no longer need to press the gas pedal to the floor to achieve the desired performance, and consequently, less fuel is consumed. However, it’s important to understand: if you use the car’s capabilities to the maximum for most of your trips, fuel consumption will increase — whether you have chip tuning or not. If your operating conditions allow for a more balanced driving style, fuel consumption may decrease by up to 20%.
How the installation process works
The installation process in IMCHIP is as transparent as possible and does not require any mechanical intervention..
- First, we find out your wishes and check whether there are any malfunctions in the vehicle. If we detect any issues, we first recommend fixing the problems..
- Through the OBD connector, we read the original firmware of the engine control unit. The factory firmware is preserved. At any time, you can revert the vehicle to the factory settings..
- Next, we load the improved version of the program.
- After installing the firmware, we conduct a test drive — we evaluate the operation of the engine and transmission, as well as the response to the accelerator pedal. We check for any errors and make sure the vehicle is running stably.
Safety and warranty. Our work does not affect the dealer’s warranty. Installation via OBD leaves no mechanical traces; the changes are not visible during standard diagnostics. Environmental settings remain intact.
The service life of the component pair is not reduced: the firmware is created based on the actual capabilities of the engine and transmission, without extreme modes or overload.
