Chip-tuning: what is good, and what is bad

The concept of chip-tuning entered the markets after the cars became completely controlled by electronics. We are smoking electronic cigarettes or vapes and reading e-books now, so, the cars aren’t an exception. Why not ride an electronic car like ford fusion, for instance? Anyway, many people are interested in chip tuning, because it allows changing the character of even the most modest car.
Let's start with the definition. What is this notorious chip-tuning? In other words, this change in the modes of the electrical controllers by correcting internal control programs. Typically, this type of tuning involves making changes to the ECU (Engine Control Unit) - the engine control unit - and is used to increase the power of the power unit. But this is not all that the chip master can promise you.
The question arises if the automakers cannot produce more powerful cars so that car owners do not have to resort to chip-tuning afterwards? Naturally, no. The fact is that companies that manufacture cars, have their own reasons for the engines not to work at full capacity. For example, the engine is often "jammed" in order to reduce the emission of carbon dioxide, thereby minimizing the "eco-tax".
What motors can be "chipped"?
If you are the owner of a “steel horse” in whose broad chest beats the atmospheric heart, you’d better give up the idea of increasing its power. The reason for such a non-optimistic recommendation lies in the fact that in the case of atmospheric engines, the increase in power by "chipping" can only be 3-7%.
But if the diesel engine “growls” under the hood, then you can count on the fact that the master will squeeze out of it an additional 25, or even 50 percent.
What is the process of "chipping"?
The car is driven to the stand to check the power and the mapping is carried out - specialists are looking for in the factory programs the data that are responsible for the engine. After that, the experts make their own adjustments, based on how large the number of regulatory parameters is. In the case of simple motors, this is the fuel delivery time and the ignition timing. Complex aggregates, for example, BMW engines, are still puzzled by the angle of the change in the timing, the height of the valves and the variable length of the intake manifold.
The complexity of chip-tuning is that the motor control unit is pretty closely related to other systems and blocks. And if you make adjustments to the ECU, then, most likely, you will need to adjust the gearbox.
The advantages of chip tuning
Before we start talking about all the pros and cons of chip tuning, we must say that all of the following points can be considered purely subjective.
Chip tuning can please the car owner by improving dynamics, saving fuel, eliminating engine "jams" and "dips", increasing the responsiveness of the gas pedal, correcting program errors and correcting the characteristics of the engine in your dodge challenger or Toyota cruiser. In general, a lot to talk about the advantages of chip-tuning does not make sense, because they are obvious.


To conduct chip-tuning or not is your own business. But it should be remembered that such changes only increase the driver's potential. The resource of the engine depends primarily not on the settings, but on the driving style and operating conditions. The main thing is competent and careful attitude to the car.

Chinese New Year Reunion Dinner At San Jose 2022

TABLE FOR FOUR... We had our own reunion Chinese New Year dinner on Monday evening.... we made a simple one, just hot pot at home.  All we have to do is to clean the vegetables, get everything defrosted... and the hot pot boiling with a packet of seasoning.  They sell a lot of hot pot seasoning over here, from tomato soup to shrimp and chicken soup, I just threw in the whole packet of paste.  No doubt not so healthy but it is so easily done....  As usual, Chinese New Year won't be CNY without a plate of Loe Sang...  No crackers so I put in a few pieces of Tacos... LOL... Most important is the sauce....  The apricot, plum sauce and honey makes it right.... And our dishes for the evening..... We ate too much shrimps the day before so we omitted for this evening.... Simple and yet satisfying meal for our Reunion Dinner....

My 6 months being a babysitter is soon over... and did I say I can hardly wait?  NO, NO... I love my job here and I am going to miss my baby tremendously!  I only don't miss his cries!  LOL...  OK, by the time I write this post, Chinese New Year is over, it is now the 4th day of CNY.  Two days before the Lunar New Year, my daughter-in-law and I cooperated fully and baked a few types of cookies.  Looking back at these pictures, I dare say that we did a good job... not on the cookies but at least we had a great time bond

Buffet Lunch At Baccanal Caesar Palace Hotel, Las Vegas

BUFFET LUNCH... We made reservation for a nice buffet a week before we came to Las Vegas, the buffet is one of its kind in Caesar Palace, Baccanal is the name of the restaurant.  My kids were saying that we must have at least one good and memorable meal while here in Las Vegas and they chose the seafood buffet.  It cost around $90 per pax and being Asians, sure we would be attracted to just seafood!  Alaska Crabs... hairy crabs....lobster claws..  clams etc etc...  Oh, I did not take much photos on what we ate, just too busy stuffing in and to take out the camera with dirty hands and all.  LOL.... Just the initial stage and after that, it was all about eating and eating... oh, by the way, they only allowed 90 minutes in the restaurant, but I don't think they timed anyone... LOL.. Anyway, we took that amount of time to finish our food, sipping free champayne and mocktail too.  What a scrumptious meal... from mains to desserts, I think we only had one meal done for that day itself...
