History

Racetech has been in operation since 1987 and is a privately owned corporation. Our main focus then was building cars and performance engines for street and road racing. We prepared and fielded several cars in several different classes until 1994 winning every class at least once. In MP2, a class spanning engines from 2.3 to 3 liters, our cars won the class every year of its existence. Most engines that we raced were turbocharged 4 cylinder types so we have considerable experience in this field. We have been turbocharging engines for over 35 years and built our own engine dyno and cylinder head flow bench for serious R&D work.

In 1990, preliminary work began on a programmable EFI system designed from the outset for turbocharged engines to replace the standard Weber type carbs being used. In 1992, this system was applied to a 1.7L turbo Toyota installed in a Datsun 240Z road racing car. Results were immediately encouraging with at least 1000 rpm being gained on the lower part of the effective power band over carbs with no loss in top end power.

Following many ergonomic improvements, we introduced the EM-1A in late 1993. The A model was followed quickly by the improved B,C,D,E and F models by 1996. In 1997 the new, single chip EM-2 was introduced along with our EIC.

The EM-3 line was introduced in November 1999. It featured a host of hardware and software improvements for improved flexibility in programming and easier installation plus injector drivers were internalized. Installation and programming manuals have been expanded and improved based on customer feedback. New versions of software were released periodically to expand programming flexibility and increase noise rejection. A new microprocessor controlled LCD programmer was introduced in the summer of 2002.

The EM-4 was introduced in mid Sept. 2002. The EM-4 installation and tuning manual has been extensively re-written with clearer instructions, photos and a larger troubleshooting section to aid customers.

On Jan. 1, 2005 V14 software was released offering AFR data logging vs. rpm and nitrous ignition retard capabilities at no extra charge. This was in response to customer requests for these features.

In April 2006 we introduced several new products for the experimental aviation market- a bolt on Hall sensor and mount for Subaru EJ series engines, a fuel and spark control system for Suzuki G10 conversions and a 3 1/8 panel mount programmer.

In the Spring of 2007, V16 software was released with improved AFR data logging and diagnostic features including the ability to drive a check engine light.

Feb. 10 2008, V17 software was released with improved ignition timing software and built in two step ignition rev limiting.

Dec. 2010, we are now supplying ECU circuit boards featuring SMT instead of through hole components.

We are the leading supplier of EFI for experimental aircraft including systems for Reno air racing Sport and Super Sport classes and a large supplier for UAV applications.

In September 2011, we introduced the EM-5 SMT ECU with a faster microprocessor and more memory.

6F coil packs ready for bench testing

Automotive wiring harnesses are built using CSA or UL approved cable and wire. Aviation harneses are built using Mil Spec Tefzel wire.

Most connections to the ECU plugs are soldered and individually heat shrunk for strain relief and retention. Outer end connections are crimped for vibration resistance and strain relieved in Weatherpack connectors. Each sensor uses an individual, sheathed cable for ease of routing and abrasion resistance so that there is no rat's nest of separate wires.


Product Testing

Our products go through several QC tests before being shipped to the customer. All ECUs and coil packs are scope or bench tested individually to check for proper function. As each order is assembled, the ECU, wiring, sensors and mixture knob are tested together as a unit to ensure proper function. Each order has a tag with the system information and options listed. As components are picked or completed, they go in a dedicated order box with the tag.

Scope testing ECU outputs

In addition to bench testing, our products are continually tested on our own shop vehicles under real world conditions. We consider this very important to ensure the highest reliability of our products and allows us to showcase our technology. Lab testing just can't simulate real world conditions, failure modes or first hand tuning and troubleshooting experience. Our fleet of vehicles has accumulated hundreds of thousands of kilometers of stock, performance and racing use with no system failures. Cold weather testing is accomplished in every day Canadian driving in temperatures down to -35C. Hot weather use is well proven in the deserts of the US and Middle East at +50C. Marine use has seen several systems submerged underwater for hours or days. When the ECUs were dried out on the dock for a few hours, they still functioned perfectly. Off road and rally use has pounded our ECUs over very rough terrain with very few problems. Multiple race wins and championships in the Baja 500 and 1000 races and punishing SCORE series show how tough our hardware is. Our 22 years in supplying systems for aviation use shows the confidence and extreme reliability of our units as does our 3 year warranty.

One ECU on a test bench ran for over 145,000 hours continuously with no problems.


Client Feedback

One of the most important tools we have to improve our products is feedback from the field. This not only allows us to bring out new features that our customers want but also to improve the software and hardware and identify problems that occur in applications outside of our normal testing means. We'd like to thank Tim Rodda, Ray Sedman, Mike Robinson, Ralph Inkster, Dave Anders and Rusty Crawford for their contributions, insights and experiences with SDS over the years.


Racetech/SDS Test Vehicles

Over the years, Racetech and SDS has owned various cars used for R&D and testing purposes. Collectively, these have accumulated nearly 1 million km running SDS EFI in the last 23 years.

How reliable is the Hall sensor trigger? When we did the timing chain, the old sensor was removed from our 240SX shop car, still in good shape after 17 years of being covered in grime and road salt. Probably over 5000 hours on it. Put it back in for a few more years.


How good is the spark on SDS ignitions some might ask? Here's a photo of an actual, badly oiled up plug removed from an SDS equipped engine. The ignition was still firing this one consistently with no misfire.


Sales, Advertising and Marketing

Racetech relies primarily on internet and word of mouth advertising to sell our products. You will see very few print ads for SDS. This strategy reduces advertising costs considerably which reduces the end cost to the customer. We both direct sell to the public and through our dealer network.

We have shipped systems to all corners of the globe with around 20% of total sales being outside of North America currently. We believe that this is due to customers embracing our reliable, easy to use system and our excellent service and tech support. Aviation sales have spiked rapidly upwards in the last few years, now becoming a majority percentage of annual sales overall.


Business Philosophy

Unlike some companies in the performance products and aviation world, we don't believe in sensationalism, BS or hype to sell our products. If something seems too good to be true in an ad, it probably is. We try to give you the facts and as much information as possible so that you can make an informed buying decision. This is a primary reason for our extensive web site. If we don't think that our product is suitable for your project or goals, we will tell you so. We realize that if you are not happy, that bad word hurts our future sales and reputation, which we have worked very hard to establish. A satisfied customer is more important to us than just a sale. We realize that our customers, in effect, sign our paychecks and try to treat them accordingly. Talk is cheap, real, positive, customer service reputations are only earned over time with real work.

When it comes to service and tech help, we are second to none. When you make an E-mail enquiry, you will always get a reply in less than 24 hours on weekdays and on Monday morning if over the weekend. We can give an exact quote on the order as well as shipping costs by fax or E-mail. We try to answer E-mail 6 days a week. We will give you phone tech help for as long as you need it and we don't make you wait on hold.

We don't BS people and we get right to work on your order once the funds are transferred. Most orders are on their way within 1-3 days unless we have a large backlog. We can provide you with an estimated shipping date before you order and supply your package tracking number. 99% of our products are shipped by air so that you have it ASAP. We will contact you if there is any delay in shipping for unforseen reasons.

This all sounds pretty good but being human, we do sometimes goof up. If we do, our pledge is to make it right ASAP, at our expense.


North America Production/ Buying Focus

Most of our products are sold within North America so we feel it is important to support businesses in Canada and the US rather than moving production and component purchasing offshore to save money. This results in higher costs than if we produced in Asia but helps preserve jobs and the economy here. We buy as much as we can from suppliers in the US and Canada and try to keep overhead costs low to be as competitive as possible. Some things are more important than profit margin, especially in the long term we believe. If you are considering buying cheaper products with less pedigree from Asia, consider the type of product and services you may be getting. Are they proven? Are there thousands in service? How is their tech support and customer service? Is that support available in a timely fashion with an 11-14 hour time zone difference? Is your money going to support industry and jobs in your own back yard or supporting the jobs and economy of a nation with little respect for intellectual property, rule of law or sense of fair play?


About our Website 08/06/99 SFZ

Our website is our primary marketing and information tool. It also allows us to update technical details and provide installation manuals online. We have a simple, straightforward approach on our site. Just like the EFI systems that we make, we don't believe in uninformative, complicated or hard to use websites.

Our site is all HTML, no scripts bogging things down. We use contrasting type on light backgrounds so it is easy to read. We don't use solid title graphics which waste ink when printing. We don't use flashy graphics which waste time downloading and are basically useless. We won't place annoying banner ads on our site. We try to keep image files reasonably small for fast downloading. We do not share or sell E-mail addresses or order information with anyone, except with your consent. Finally, we don't add code to create nag screens or pop-ups to other sites.

We feel that a website should be like a book with pictures. Click on the page that you want and read it in a vertical fashion. It should contain factual, useful information which is broken down into logical sections. It should be updated frequently with dates listed at the top of the home page. We will continue to use this philosophy in the future until we think of something better. We don't believe in flash without function here.


E-mail response

We treat E-mail querries like telephone calls if we can by answering them as soon as possible. We check our E-mail first thing in the morning and usually at least 3 more times during working days. Whenever possible we also check it on weekends. In this electronic age, we feel that these things need to be answered in a timely fashion, not discarded or forgotten about for several days as many companies seem to do.
