Electronic Control Module Tuning With The Unichip Q

blogger

The up to date Sequential Electronic Fuel Injection Control System is made of sensors which observe the actual engine requirements, the Powertrain Control Module (PCM) which operates the particular system primarily based on return signals from these electrical feedback sensors, as well as actuators which are powered under the control of the actual ECM.

The ECU (Engine Computer) carries out activities such as fuel injection control, idle air control, and spark ignition control.

In addition, the Powertrain Control Module is loaded with many different diagnostic test settings which usually streamline trouble shooting any time a new trouble code appears.

The two most common calibraion tables that you need to manipulate or modify is undoubtedly the timing map and as well fuel map

Ignition timing control

The ignition power transistor placed located in the ignition main circuit turns ON and OFF in order to regulate the main current rate to the ignition coil. This controls the ignition timing so that it will generate the optimal ignition timing with regard to the engine performing conditions. The actual ignition timing is determined by the ECM (aka The Blackbox) as a result of rotational speed, air flow, engine coolant temperature (ECT), and atmospheric pressure.

Injector control

The injector open milliseconds (MS) as well as injection timing remain controlled so that the perfect air to fuel mixture is delivered to the engine to correspond to the continually-changing engine operating conditions. A correctly scaled injector is mounted in the intake port of each cylinder. Petrol is sent while under pressure (around 55 psi) coming from the gasoline tank to the actual fuel injectors through the fuel pump motor, with the actual pressure being regulated by the fuel pressure regulater at around 55 psi. The controlled fuel is then distributed evenly to each one of the injectors. Sequential fuel injection is usually performed one time for every cylinder per two rotations of the crankshaft. On a four cylindr engine the firing order will be 1-3-4-2. Each cylinder has a dedicated gasoline injector. This is known as multiport injection. The ECM (Engine Computer) provides a richer air/fuel mixture by carrying out “open-loop” control when the engine is cold or operating under high load conditions in order to maintain engine performance.In addition, when the engine is under normal operating temperature after warming-up, the ECM manages the air/fuel mixture using the heated Lambda sensor signal to handle “closed-loop” control. The closed-loop feedback accomplishes the theoretical Air-fuel mixture ratio where the catalytic converter can obtain the absolute maximum clean-up operation.

Using the Unichip Q-plus you will have total control over these variables to make alterations to the timing and fuel calibrations. The Unichip PnP has 24 RPM sites between 100 RPM and 24000 RPM and 13 load sites between closed throttle full throttle position. This equates to 312 available tuning points for each map. In turn the Unichip PnP is going to interpolate in between each speed and load site 16 times which gives a decent resolution densed map.

UniQ is Unichips most recently released software package for tuning engine ECU’s. This software program is a revolutionary change from old style DOS model which had been in operation for over a decade. Take the Unichip Tuning software for a test drive and see for youself.

Video Game Industry Stocks Why Is Electronic Arts More Expensive Than Activision

blogger

I was looking through gaming stocks and noticed that shares of Electronic Arts (ERTS) are trading at a much higher valuation than Activision Blizzard (ATVI). That made me wonder, Does Electronic Arts deserve to trade at a premium to Activision?

Electronic Arts is trading just under $20 per share. EPS estimates for 2010 are 43 cents per share and 62 cents for 2011. That equates to a 46 multiple on current years earnings and a 32 multiple for 2011. The 5 year growth rate is 12.8%, which is pretty optimistic considering the negative earnings growth of the past five years. Its tough to have faith in Electronics Arts management considering the poor operating efficiency. Management has graced us with a negative ROE and ROA over the past few quarters.

One of the bright spots for Electronic Arts is the companys storied brand name and solid balance sheet. Electronic Arts has cash cow franchises Madden NFL, The Sims, Battlefield, Rock Band, etc. The software developer has $1.78 billion in cash and no debt. The stock looks expensive using any valuation method including price to book and price to sales. Shares of Electronic Arts appear to be benefitting from improving trends in the video game industry. Video game sales rose 10% last month.

Activision Blizzard is trading just under $12.00 and has a expected EPS of 73 cents for 2010 and 82 cents for 2011. 2010s PE ratio is 16 and 2011s is 14.5. Earnings growth is estimated at 14.6%. Activision raised 1st quarter guidance last week due to strong sales from Call of Duty: Modern Warfare 2. While ROA and ROE are not very impressive, at least both numbers are positive for Activision. The management team has done a qualitative job at Activision with its acquisitions and ability to consistently grow the bottom line.

Compare this with Electronic Arts who has been trying to fix its internal problems for years. Activision has no debt and $3.25 billion in cash on its balance sheet. Shares are currently trading less than 1.5 times book value. Activision has a popular lineup of games including World of Warcraft, Call of Duty, Guitar Hero, and Starcraft.

The Development Of The Electric Bass Guitar

blogger

Although the concept of a bass guitar was first developed in the 1930s, it wasn’t until the 1950s that mass production met with popularity and the concept of an electric bass guitar became mainstream. Once the idea of an electric bass guitar took hold, and was used widely in groups and bands performing across the world, many companies began developing new styles and methods to create some fantastic ideas for the instrument, and help its popularity grow. Today the electric bass guitar has stepped forwards from the dark shadows of the back of the stage to take a much more prominent position at the front – and has become known as a very popular and stylish instrument to play. Not forgetting, of course, that the quality of sound and versatility have come a long way too.

Since it took about twenty years for the idea of an electric bass guitar to become a mainstream popular idea, it is unsurprising perhaps that it took another twenty years for the next big jump in design and innovation. It was in the 1970s that the company known as Music Man was founded by Leo Fender. It was this company that designed and created the StingRay, which was the first bass guitar to include active electronics. Although these active electronics can sound quite complex, the simple effect was to increase the range of high and low notes, and enhance the crispness of each.

In the early seventies a company called Alembic created the basic design for the high end bass guitars, known as boutique guitars. These were crafted using the highest degree of expertise, with the most highly skilled craftsmen using the finest quality materials. With unique, custom designs, the most premium woods available and some of the most innovative electronic gadgetry included, these boutique bass guitars became well known as the top guitar to have – and brought bass guitars from the back of the stage to the very front – an equal to the standard electric guitar.

Over the next thirty years the designs of electric bass guitars have varied, with new innovations, odd and unusual features and designs, including a headless bass by Ned Steinberger, who also introduced the Trans-Trem tremolo bar. A few years later the Guild Guitar Corporation introduced the astonishing fretless bass, known as the Ashbory. Quite how a guitar would work without frets would challenge any sane thinker – but the Ashbory used silicone rubber strings, with a piezoelectric pickup. The result of this was a sound more like a double bass than an electric guitar.

It was in the nineties that five string basses became popular, and prices began to reduce quite significantly, seeing pre-amplifiers built in to most bass guitars – previously something reserved for the higher end guitar. Today we see electric bass guitars include digital modelling circuits actually built in to the guitar – almost like having a computer built in to the body of the guitar, and able to enhance, distort, amplify and altar the voice of the guitar in such a way that it is possible to program the guitar to sound like any of the well known types of guitar available previously.

Electronic Cigarette Reviews Green Smoke Vs Blu Cigs

blogger

I began my journey writing electronic cigarette reviews by purchasing a Green Smoke starter kit in December 2010. Then two months later, in January, I bought a Blu Cigs starter kit. Today I want to discuss the primary differences between these two key brands.

Introduction

For starters, both Green Smoke and Blu Cigs are the top two e-cigarette manufacturers in the entire world. As such, they’re based in the United States. Blu Cigs specifically caters to U.S. citizens, whereas Green Smoke prides itself on delivering to smokers from all across the world, including France, Egypt, and even China.

Obtaining My Kit

To write electronic cigarette reviews, you have to actually dabble with the products. So I ordered my Green Smoke kit in December and was pleasantly surprised to discover it outside two days later. Blu Cigs, on the other hand, I ordered a month later, and I was quite disappointed because my e-cigarette kit took ten tediously lond days to arrive. So when it comes to delivery, Green is the winner.

The Starter Kit

My Green Smoke starter kit included one battery, two chargers, and five cartridges, whereas my Blu Cigs starter kit featured two batteries, three chargers, and give cartridges. In addition, one of the Blu chargers was a ‘charging pack’ designed to not only charge an electronic cigarette, but also designed to store one e-cigarette are a few cartridges. So it was essentially a case. The winner here should be obvious!

Accessories

Green Smoke offers a bevy of accessories, including a car charger, two cases, a special pink battery, and rubber sanitation tips. Blu Cigs unfortunately only offers all the items that were in my starter kit: three chargers (none of them were a car charger) and one basic battery type. That’s disappointing.

Flavors

Green Smoke has a whopping twelve cartridge flavors, but most of them taste horrible. Mind you, other electronic cigarette reviews might disagree. I do really like their chocolate flavor, though. As for Blu Cigs, it only has four, but each of them taste like bliss: tobacco, menthol, cherry, and coffee.

Cartridges

Green Smoke cartridges are equivalent to 30 cigarettes, and they create a lot of vapor. Blu Cigs cartridges are only equivalent to 21 cigarettes, and they create slightly less vapor, though not too much less. Both cartridges come with an integrated atomizer. I found them both to be impressive in this category. The weaker 21-cig cartridge didn’t concern me simply because they’re cheaper (See Prices).

Prices

Every electronic cigarette starter kit, battery, charger, and additional accessory for Green Smoke costs a fortune, whereas every piece from Blu Cigs doesn’t cost that much at all. In particular, Green cartridges retail for $2.80 a piece, while Blu cartridges retail for $1.92. Keep in mind the latter don’t last as long.

Discounts

Since Blu is so cheap to begin with, there are no discounts. Green, however, offers a whopping 10% discount courtesy of codes such as DISC10-19544. Both e-cigarette manufacturers include an option for free shipping.

Conclusion

Most electronic cigarette reviews end up telling you which e-cigarette to buy. I’m not going to do that. It’s not a question or whether Green Smoke is better than Blu Cigs or vice versa. Rather, it’s a question of which brand is better for you. What’s more important to you? Flavor? Price? Accessory options? Discounts? What is it that you want?

I will say this. My personal electronic cigarette choice is Green Smoke. I started with them and I plan to continue with them. I sincerely believe that they have a better product. More importantly, they are the only electronic cigarette brand to offer a delicious chocolate flavor. I don’t know about you, but I love chocolate!!!
