Hi, Guys!
I'm new on the forum. I have read here a few topics about electronic systems used with hho to „cheat” an engine and now I'm really impressed about it.
I decided to install a chip in my car and thus I would like to ask you some questions to know more details about this issue.

I found some shops and products on the internet:
http://voloperformance.com/fs2hhoedition.html
http://www.hhokitsdirect.com/mileage...-generator.php
http://www.hho-plus.com/product.php?id_product=16

1. What are your opinions about those chips? Why do Volo chips exist in several different versions?

I'm afraid that this huge discount of Volo chips and their programming software could be due to their old technology. Am I right? What are the differences beetween Volo chips offered here:

2. Which company produce the most technology-advanced chips?

I have heard that new models of chips (such as HEC) are faster. It is said that they save much more fuel than the older ones.
3. Is there any visible difference in quantity in economized fuel?
4. Does the new chip provide better safety for our engine than the older one?
5.What are the other benefits?
6. Are there any differences between methods of measuring parameters of the air, fuel and fumes?
7. How to compare two chips of two diffrent producers, on what should I pay attention while choosing the chip?

On the market we can also find Ogo chips, there are three different models:

http://www.ogohho.com/index.php/prod...uel+Saver.html

http://www.ogohho.com/index.php/prod...+Inspirer.html

8. Where we can use each type of them? What is your opinion about them?

I'm also intrested in programing chips. I found this aplication:

9.Is there any other producer of chips who also gives possibility of programming them?
10.Can you recommend me companies which give that possibility? The other
required feature is database of cars which is updated and well-developed by the producer.

I don't know exacly what are the most common ports used in ECU.

11. The most popular type of port of ECU is OBD 2, right?
12. Is there any other version of that connection?
13. Is it availible to connect one type of chip to every type of car computer? Does it depend on ports used in ECU?

I'm sure that you can resolve my doubts. Please, help me with these issues.
I speak English as a foreign language, so please make allowances for me.
