The ID2600-XDS is the most recent offering from the partnership of Injector Dynamics and Bosch Motorsport.

The ID2600-XDS was developed specifically for use with liquid fuels, featuring corrosion resistant internals, and long term compatibility with ethanol and methanol.

The ID2600-XDS has the highest flow rate of any injector offered by Bosch, and flows 50% more than the ID1700x.

The ID2600-XDS benefits from Dual Slope Matching, a method of matching the flow rate in both the linear, and nonlinear operating range, providing better cylinder to cylinder consistency at low pulse widths.



What is Dual Slope Matching?

Dual Slope Matching is a method of matching injectors that provides the best possible cylinder to cylinder fueling across the entire operating range.

Traditionally, injectors were matched based on static flow rate alone, which resulted in large deviations at low pulse widths.

Injector Dynamics introduced Slope Intercept Matching over a decade ago, which provided even cylinder to cylinder fueling across the linear operating range of the injector.

With the progression of turbo technology, and increased use of alcohol fuels, greater demands are placed on fuel injectors, and they are often required to deliver fuel well outside of their linear operating range.

The concept of Dual Slope Matching extends the injector matching into the lower non linear operating range. Dual Slope Matching was conceived by Aaron Looft of Injector Dynamics, who was inspired by the dual slope injector characterization model used by Ford.

How Does Dual Slope Matching Work?

Let’s first consider static flow matching which was the industry standard prior to Injector Dynamics.

The graph below shows the dynamic response of two hypothetical 1500 cc/min injectors within their linear operating range. One with an offset (Dead time, latency, etc.) of 0.95 milliseconds, and one with an offset of 0.85 milliseconds.

The slope of both lines is the same, as they have the same flow rate, but the difference in offset results in the injector with the higher offset delivering 2.5 uL less fuel per injection event. At a pulse width of 19msec, which equals 90% duty cycle at 6,000 rpm, 2.5ul amounts to a mere 0.6% difference in flow between the two injectors, but at 2msec, that same 2.5ul difference amounts to a 9.5% difference!

Slope Intercept matching as introduced by Injector Dynamics in 2007 solved this problem by matching injectors based on flow rate (Slope) and offset (Intercept) providing even cylinder to cylinder fueling across the linear operating range.

Moving on to the non linear operating range, the graph below shows a pair of 1500cc injectors matched using the Injector Dynamics Slope Intercept method. Both injectors have the same flow rate and offset, but in the non linear range, the flow deviates from the straight line shown in the graph above. In this case, the flow rate, or slope of each injector in the non linear range is 1530cc/min and 1470cc/min representing a spread of +/- 2%.

As the graph clearly shows, the difference between the two injectors increases as pulse width decreases.

Shown as percent difference in flow, we see that even though the injectors are matched perfectly in the linear operating range, the difference in slope in the non linear range results in a flow mismatch that is magnified as the pulse-width decreases, becoming substantial at the very lowest pulse widths.

How Well Does This Work in Practice?

Moving from hypothetical injectors to a real world application, the response in the non linear range is considerably less orderly than shown in the graphs above, and is quantified using a technique called Least Squares Linear Regression – Which is a fancy way of saying straight line approximation.

By approximating the response in the non linear range, and matching sets accordingly, the best possible cylinder to cylinder fueling is realized across the entire operating range.

Using the ID2600-XDS as an example, the traditional Slope Intercept method of matching results in an average deviation of +/-5.1% in the non linear range, while the new method of Dual Slope Matching has reduced this to +/-1.4%

In a perfect world, this deviation would not exist at all, but for those of us who live (And tune!) in the real world, Dual Slope Matching represents a large step forward, and we are proud to offer it to the market.

New to trauma therapy; loved the book
Format: Paperback
This book was required reading in my Trauma & Intervention class and I loved it so much that I kept it. It is easy to understand if you are new to trauma therapy (which I am). I refer to it fairly often and have absolutely put what I learned to good use. I truly believe this book helped make me a better therapist.

biblical and scientific
I never thought I would say this, but a relationship book has made it to my top ten favorite books. I felt like it was really good premarital counseling in book form. I've had premarital counseling, and it was actually pretty good, but this book was much, much better. This book is really well written, and the content ranges from the general (for instance, telling you that men and women have different needs) to the specific (for instance, giving suggestions for how to tell if you are still "in love" with someone, or if you just see them as a really good friend you happen to be engaged/married to). This book draws heavily from Gottman's research on marriage. While his work does have its flaws, it's important to note that it is easily the best research on marriage that anyone has ever done. Most marriage theories are based on the author's opinions and what they have seen work for a few couples here or there, but Gottman has done the leg-work so that this book can present some actual empirical understanding of the basics of a good marital foundation. This book also draws heavily on Biblical principles of love, relationships, and marriage. It is unapologetically Christian and suggests at the end of the book that even if a couple is doing everything "right" they need to share spiritual dreams and Christian service. I read this book by myself when I got engaged to my boyfriend of a couple of years. The book has questions at the end of each chapter to help you consider how the material in the chapter applies to your specific situation. I took the questions seriously and by about 1/3 of the way through the book I realized that I really couldn't marry my boyfriend. I had a hard time letting go of the relationship but in hindsight it was a really unhealthy situation. My friends had been telling me their concerns but I needed to figure it out for myself, and this book walked me through that process in a really low-pressure gentle way. When I started dating my now-husband I started reading the book again and answering the questions in regard to my new relationship. It was really reassuring for me to see that we were built on a solid foundation. I decided to start over and read the whole book together(which we mostly did in the car) and discuss the questions together. This was probably the best thing we have done for our relationship. It helped us have reasonable expectations for each other and ourselves, and helped us set up good habits as we started our marriage together. One thing to note: apparently there is a man's workbook and a woman's workbook to accompany this book. For budget reasons, I didn't purchase the workbooks. The book was still extremely helpful for me and my husband, but every few pages it directs the reader to an exercise in the workbook. Some of the exercises looked interesting and others looked repetitive or boring. Discussing the questions at the end of each chapter was enough for us.

Best Marriage Preparation Book
As a pastor of 25 years, I have used several books as part of a pre-marital counseling regiment. This is the best, by far! Not only do the Man's and Woman's Workbooks (I suggest ordering them with the book) make premaritial counseling simpler, I have found that this book hits the nail on the head. Couples who went through the material in preparation for marriage thanked me after they were married, and they shared how valuable this material was in the daily grind of life. I first heard the authors at a Moody Pastor's Conference in the late 1990's. It did not take me long to determine that I would check out their books. I have since concluded that Drs. Les and Leslie Parrott are exceptional in the realm of understanding human relationships. Althogh the book is written by a godly Christian couple, this is more of a relational book than a spiritual one, so I would not consider it a complete pre-marital regiment, but a good anchor book. Whether used in counseling or simply read by a couple in their own quest to prepare for marriage, this book is a gem. The Drs. Parrott seem to have a realistic (and well documented) grasp on the nature of marriage. This is practical, hands on material. The book is arranged around 7 questions: Have you faced the myths of marriage with honesty? Can you identify your love style? Have you developed the habit of happiness? Can you say what you mean and understand what you hear? Have you bridged the gender gap? Do you know how to fight a good fight? and Are you and your partner soul mates? Of course no couple entering marriage could honestly answer all those questions with a "yes." But the book provides a good start and helps couples begin to face reality and potential areas of growth. If a couple follows the exercises by purchasing the workbooks, (like identifying some of your own personal "commandments"--rules you live by that you picked up who knows where and expect your spouse to know and agree with), it could preclude many potential tensions later. This book could also be used as a marriage enrichment manual. Indeed, many couples (perhaps most) have probably failed to incorporate these solid principles. Indeed, several couples I counseled have identified this exercise as having made a significant difference in their marriages. To those of you considering marriage, go through this book together, and cosider at least some of the exercises in the workbooks. To pastors and Christian counselors, I urge you to read this volume and consider using it!

Inexpensive, yet extremely helpful
Well written book that can be helpful not only to newlywed couples or those engaged, but also to those who have been married for a period of time. They are thought provoking and encourage dialog on a variety of marital issues. The companion workbooks for each respective spouse is nice.
