Plug n’ Play Data

Are you tired of pouring over logs, making corresponding changes to your tune, only to find that what worked one day is off by the next? Have you wasted hours sifting through a myriad of injector related forum posts, only to find that there is no simple solution? Such is the nature of tuning with inaccurate injector data.Accurate injector characterizations are the basis of all fueling calculations, so it’s no wonder that if you’re tuning without them, you will spend a lot of valuable time making the best of a bad situation. It will keep you busy searching for endless combinations of mostly incorrect answers, and it will rob you of the most basic functions provided by the guys who spent millions of R&D dollars designing the engine management system for your car.

Whether you are a professional tuner, or an end user, you can spend countless hours getting it “mostly correct” or you can copy and paste accurate characterization tables and get on with the job of maximizing performance and drivability.

Injector Dynamics is the only motorsport injector supplier capable of generating these OEM quality injector characterizations, and our engineering services are available to generate data for new platforms and applications at no cost to our customers.We welcome the opportunity to provide solutions where none previously existed, and it is this commitment to value and innovation that has earned us our position as the industry leader.

With the ID1300x and ID1700x setting the current standard for high flow injectors, and the recent release of the ID1050x, many are asking what makes these injectors perform at such high levels.

The simple answer is intent. It is no surprise that an R-Compound tire designed for track use will outperform a standard street tire, even if both come from the same manufacturer.

The same can be said for the performance of the ID1050x, ID1300x and ID1700x, which are designed specifically for motorsport use.


Combined Expertise
The partnership of Injector Dynamics and Bosch Motorsport was formed to combine the unique abilities of two industry leaders, and offer the resulting technology to a new breed of racers.

From import vs domestic drags, to time attack and airport racing, these high boost alcohol fueled engines exceed the capabilities of re-purposed production car parts, creating the need for a purpose built high flow motorsport injector.

Technology is nothing, until it provides solutions. In the case of the ID1300x and ID1700x, our customers made the needs of the market clear. Our job was to pay attention, and develop solutions that would meet those needs. Those needs, and the solutions are described below.

High Impedance
The complexity of modern engines often exceeds the capability of aftermarket ECU’s, necessitating the use of OE based hardware and strategies. Peak and Hold injectors, being decades old technology, are not supported by modern hardware, and so the X Series injectors are based on the high impedance Bosch EV-14 architecture.


High Flow
While achieving high flow may seem easy, it poses significant challenges if the resulting dynamic response is to be useful.

Much like the heads on your engine, the valve in the injector can only be opened so far before other problems arise. The challenge then becomes balancing flow against acceptable operating characteristics.

In the case of the ID1300x, all available parameters were fine tuned to achieve the best results, with the ultimate flow limited to ≈ 1300 cc/min to avoid degrading the characteristics critical to operation in a motorsport environment.

Namely, voltage sensitivity and pressure sensitivity described below, and low flow linearity and minimum fuel mass.

At the time of its release, the ID1300x was the highest flowing all fuel compatible high impedance injector on the market.


Racers being what they are – they quickly ran past the limits of the ID1300x, requiring even higher flow.

The ID1700x came next, incorporating unique solutions to the challenges encountered during development of the ID1300x. Namely, the problem of achieving higher flow without degrading critical operating parameters.

A study was conducted to quantify numerous modifications to the flow path, and resulted in a unique valve and seat assembly, parts of which are manufactured in house by Injector Dynamics. The end result is increased flow without the need to “open the valve” excessively.

At the end of the nearly two year development process, eighteen different variations had been built and tested. Combined with numerous “tunable” parameters, more than 100 variations were tested, and the results speak for themselves, with the ID1700x being used on record setting cars in nearly every form of racing.


Broad Operating Range
If there is one requirement that stands out above the rest, it is the capacity for a broad operating range. Unlike OE applications, where an injector is designed for specific operating conditions, a motorsport offering requires that an injector serve everything from a twin turbo V8 on alcohol, to a 14,000 RPM Hayabusa engine on gasoline.

This requirement is met by offering consistent operation across a wide pressure range, allowing the end user to change the effective flow rate.

While most injectors will run static at high pressure on a test bench, few will perform well dynamically at those same pressures, and even fewer at high temperature with less than ideal battery voltage.

In the case of the ID1300x, this challenge was met with the combination of a high current coil, optimization of numerous internal parameters, and an ultimate flow limitation of ≈ 1300 cc/min at 3 bar. The end result is an injector with impeccable manners, excellent pressure and voltage sensitivity, and a flow rate of ≈ 1900 cc/min at 6 bar.


In the case of the ID1700x, optimization of tunable parameters was not enough, and unique solutions were required.

The ID1700x features a more powerful proprietary magnetic circuit, with parts manufactured in house by Injector Dynamics.

The result is pressure and voltage sensitivity exceeding that of the ID1300x, requiring only 9 volts to open consistently at 6 bar, and a flow rate of ≈ 2640 cc/min at 7 bar.

The ID1050x – the latest addition to the X Series – offers an even greater range, requiring only 8 volts for consistent operation at 8 bar, with an extended range of 1940 cc/min at 10 bar.

While voltage requirements and ultimate pressure capability may seem little more than bragging rights, these capabilities become critical when trying to hot start a heat soaked engine with a high pressure fuel system and a lightweight racing battery.

(We know at least a few of you are nodding in agreement as you remember that long day on the dyno…)

Compatibility With all Automotive Fuels
Another key requirement is compatibility with all automotive fuels.

From MTBE, to ethanol, the X Series are compatible with everything but dirt. Every dimensionally critical part inside of the X Series is made from corrosion resistant material, making them compatible with all fuels, and providing better long term consistency when used with corrosive fuels.

Talk is cheap, and at the end of the race weekend, results are all that matter.

After two years on the market, ID1300x equipped cars have set records in nearly every form of racing, from snowmobile drags, to land speed motorcycles.

The ID1700x accomplished the same within 6 months, and coming from the same technical partnership that created them, we expect the same from the ID1050x.

Ask yourself – what is your intent? Are you taking grandma to the grocery store, or trying to win a race? Choose your injectors (And tires…) appropriately.

The ID2000 has set the standard for linearity and control in a large injector. Flowing in excess of 2000cc/min at 3 bar, the ID2000 will also provide a smooth stoichiometric idle on E85, and it will do all this while maintaining strict linearity up to 95% duty cycle at 9000rpm.
With a pressure capability of 9 bar this injector can flow as much as 3700cc/min with excellent low pulsewidth linearity, and has the broadest operating range of any injector on the market.
