Today is a case of 19 BMW 425i upgrading ECU. In actual driving, the original car instantly increased speed well, but in the later period, because it was only 184P P, its performance was weak, and the owner was questioned by friends. "Don't pursue any power of 425i, choose 430i if you want power." With the mentality of never compromising on power performance, choose to upgrade the first-order ing special program by brushing ECU!

19 BMW 425 is not much different from the old model, and the roof line is still dynamic and elegant. M sports kit, equipped with rearview mirror cover in the same color as the body, chrome-plated high-gloss exhaust pipe trim, black high-gloss side air outlet trim and other decorations. Use a folding fully automatic open-close hardtop convertible. When you drive it, it's "really chic"!

In terms of power, the 425i model is equipped with a 2.0T low-power engine, with a maximum power 184 horsepower and a peak torque of 270 Nm.

The rival 430i is equipped with a 2.0T high-power engine with a maximum power of 252 HP and a peak torque of 350 Nm. The gap is still very big! Now let's recalibrate it.

First of all, the test drive and log collect the original car data stream.

Then select AT equipment, read the original ECU program, package it with log information and nameplate and send it to headquarters.

It takes about two hours for the program to return to the original car.

Finally, repeat the road test, 0 1 test and so on. If not, readjust until the customer is satisfied.

0 1 measured 6.4 seconds.

Comparison of data before and after upgrading of BMW 425i-

Original factory data: horsepower 184P torque 270NM；;

First-order data: horsepower 260P, torque 400NM.

Road test: 0 1 The test has explained everything. The original factory is 8.4s, and the first order is 6.4s. The owner bluntly said, "I dare not step on it!"

The data of this model has been measured by horsepower machine. Example: The video was made and tested on the same Pigou horsepower machine on 425i, but it turns out that real gold is not afraid of fire. 222 horses on board, standard B48 first-order special adjustment data!
