Currently the ID725, ID1000, ID1300, ID1700 and ID2000 sets are completed, please email us at support@injectordynamics. I have an 06 3500 with a fresh rebuild. 5 mS. A range of 1. Processes with lags or time constants (tau) longer than their dead times (td) are reasonably easy to tune. Siemens 830cc fuel injector has been custom-fitted, and factory flow-matched for Sport Compact vehicles. 5psi 5 Bar 8 Volt* 1. 018 ohms: That’s a clear indication that there was a fox in this henhouse. The fuel pressure regulator (fuel control actuator) in the high pressure pump controls rail pressure. Use for Toyota, Mitsubishi, Nissan, Mazda, Hyundai, etc. ISOLATED FUEL Flash Code 77 is used for several DDEC information codes. Injector dead times, offsets, flow rates, and slopes for ID injectors. Did you ever do the starting fluid spray test? It has been recommended to fire injector earlier rather then later. 8Ω) Part number 63517; Flow rate 800cc/min, (true flow rate may be 850cc/min) Bosch Fuel Injector 2200cc Short Length (CNG) (Product Code: BSS2000) Specifications: Nominal Flow Rate: 2200cc / min @ 300 kpa / 3 Bar; Nominal Flow Rate: 2550cc / min @ 400 kpa / 4 Bar If the problem is a closed or dead injector, the long-term fuel trim may have compensated enough so that the voltage doesn’t change. Congratulations, you should be able to get the engine started now. NefMoto > So do you used the dead times for base fuel pressure or idle fuel pressure? Or Hi, my car has just under 90,000 miles. * Injector data is useless without knowing the test pressure used. Wiki. Dead time can be most simplistically defined as the time Injector type Q-stat with 300 kPa (ml/min) Sidefeed, for MPi longer spray end 0 280 155 749 A 280 431 824-18 0 280 155 750 0 280 155 751 0 280 155 752 A 289 S31 203-21 have a 1993 gmc topkick with a 3116 . So a significant part of the constant for those blue injectors is a result of their dead time. Although injector response times vary from injector to injector at a given r/min, each individual injector response time should remain relatively consistent from one firing to the next. Retail Price (Without Tax) 210cc: TOP: High: 1: Blue: Oval: 0. 636cc for 720cc). 225 The injectors incorporate a multi-hole disc fuel delivery nozzle with a wide cone spray for maximum fuel atomization. If you paid your tuner to do a job, he should send you a new tune with the proper injector size. au Injector DeaDtIme charts Part No. 0 Powerstroke Injector - For those customers who are seeking an injector a 'cut above the rest' we now carry injectors remanufactured by the company that built them in the first place. The deadtime value that you see for different injectors is simply the number that the ecu adds to its set deadtime for the stock 450cc injectors. They are applied at all times. The injector o rings that seal the tip of the injector with the intake manifold and fuel rail. Injector Off Time Curves (milliseconds) Injector Voltage Supply (V) Rated Injector Flow* (lb/hr) Injector Flow and Part Number Holley EFI Injector Flow and Injector I have a 1999 Chevy Lumina it was cutting back a little and cut off a few times engine light came on. Bosch injector sizing guide 2 1/2" (64mm) injectors require 12mm (7/16") rail spacers when using the S4 intake manifold and fuel rail. We have known Russ Collins , who was inducted into the Motorcycle Hall of Fame, since 1974. 00), AND LIFETIME WARRANTY TO ORIGINAL OWNER. Fuel injectors in cars typically last between 50,000 and 100,000 miles. Once you've located the ‘dead’ cylinder and are sure that the problem isn't caused by an ignition system issue or low compression the next step is to test the resistance of the fuel injector (that belongs to the ‘dead’ cylinder). I'm guessing you might need a new injector. we put cleaner in and ran the car in yard a while because we were scared it would cut off on us elsewhere. Guys. The injector is bad and must be replaced. Note that all charts are rated at FUEL PRESSURE DIFFERENTIAL across the injector, not simply rail pressure. This time the injector pulse width was set at 5ms and the interval set at 100ms. The intrinsic dead time of a detector is often due to its physical characteristics; for example a spark chamber is "dead" until the potential between the plates recovers above a high enough value. The ID1700x is the most recent offering from the partnership of Injector Dynamics and Bosch Motorsport. Ideally you want to be able to run larger injectors at a lower fuel pressure, however, without additional fuel management this is not possible. The Best Product available for Fuel Atomization and Injector Control I don't doubt the injector dead times vary with ecu. Scale the injector slope correctly, then walk through the injector off set table (on the street, or use the dyno to vary the loads like I do), watching system voltage and manifold vacuum, tweak that table until your fuel trims come in line. Aftermarket Fuel Injector Flow Rates, Dead Times, and Resistance Data. com for additional data set The Fuel Injector Test. 212 lb/hr Siemens Deka Fuel Injectors Low Impedance Gas & Flex Fuel Injectors (Long Style) EV1 Connector Bosch EV14 35 lb/hr 0280158227 Injector. The right fuel injector must combine the elements of fitment, coil impedance, flow rate, and tuning data into one injector specific to your engine's needs. 5 PSI, 2150 cc/min at 3. The reason is that the code is adding the injector dead time to the cranking pulse width, and if your dead time setting is high enough, it can be enough pulse width on its own to flood the engine. 95 each plus core (Normally $223. 3 Cummins that has some white smoke at idle, so I cracked open the injector lines to see if I could find a week or dead cylinder and stop the smoke. This ain't the land of OZ and I'm not the Wizard 67 Designs phone mount, Rugged Ridge hood catches, dead pedal, ventshades, rampage windshield tie down & stops, solid stainless lugs, 20% front tint, sill guards, FMF spare delete kit, OffRoadHeros cargo top, K&N FIPK intake, Smittybilt Molle roll bar covers, and lots of carbon fiber hydrographics. Despite the high flow rate, they are linear and controllable at low pulse widths and have been used in ULEV applications! Things like injector dead times and the flow rate are 100% correctly modeled in the code. . 7,331 likes · 23 talking about this. If you are using an RS4 fuel rail you will need a 1" spacer! 1 1/2" (37mm) injectors require 15mm (9/16") injector spacers with the S4 fuel rail. First of all, a flat line would tell you the injector is dead or is not receiving voltage (depending where the line falls on the screen). If the injectors are very close to the Injector Dynamics 1700cc injectors, i would see how close this data is to them and maybe just use the ID data as it is more complete and will work better if trying to use the modelled fuel mode. Flow Rates: 210 lbs/hr at 43. I am having trouble getting the injector pump timed on a 1980 7700 Ford with a Simms pump. Ready to ship. We have found that generally the dead times need to be higher than what ID quotes. (the best test for this uses a gauge and is called by Suzuki the Residual test, or a real leak down test. Fuel Injector Spotters Guide and Information: So, how much power is this injector good for? That depends on the air/fuel ratio that is used, but a good rule of thumb is to divide this flow figure by 5 to get a hp capability. what do you mean voltage to both sides? disconnect the connector on the injector. that incorportate a "LONG" body injector with 11mm fuel rail and 16mm intake. Hello all, I did some searching and found little info on what all influences the Injector balance rates. I would be going back to your tuner and getting him to recalibrate for the rdx injector sizing and dead times This right here. (Remember that a fuel injector can work properly when cold but go open when hot, or vice versa. For starters, the location of process instrumentation should be considered thoughtfully as it limits the negative effects of Dead-Time. These fuel injectors can be cleaned by pulsing them thousands of times while they are in an ultrasonic cleaner. The SAE J1587 equivalent code for Flash Code 71 is SID 001/1. INJ - 139 Base Fuel Pressure in psi / bar 29psi 2 Bar 43. Shop for FICHT and ETEC Injector Services. 1ms dead time, but in the ecu it has dead times for various voltages. However, you injector size is low - it should be closer to 900cc than 715cc. Injector Options by ECU Type Stock ECU. . Another effective test is to measure the pressure loss in the fuel rail when each injector is fired and pulses for a set period of time. put 12+ to one of the terminals and ground to the other. I havent found the actual dead times, however, my buddy is using them in his 07 si. Of course, over a period of time, the coils in the spool valve can also fail, resulting in a dead injector. Just make sure you are hitting the right injector. You may have to register before you can post: click the register link above to proceed. com. Ed, the M-9593-E303 off Ford's website is a for real Ford calibration sheet but it may not be representative of a 160b/hr injector. Since the injector is dead it doesn't matter if you break it. Fuel injection is the introduction of fuel in an internal combustion engine, most commonly automotive engines, by the means of an injector. Because the fuel rail, the injectors, and the intake manifold are separate components, they require a seal when they are fully assembled and secured together. 0L V8 Dead times come from proper testing and should be outlined by the manufacturer of the injector. Currently the injector bench at FAST does not show dead times. It is a dead Injector Data. If an injector design exhibits really slow transit times for opening or closing, it will result in more non-linear behavior at short pulse widths, and more piece-to-piece variation amongst a set of injectors. It is the most recent offering from the partnership of Injector Dynamics and Bosch Motorsport, and is the result of lessons learned during development of the ID1300x, and ID1700x. A fuel injector can be cleaned many times, but it will eventually wear out and need to be replaced. The timing and duration are We have injector dead times to help the fueling of the injectors to stay linear over different voltages and pressure ranges Now comes the other areas that injectors are hardly modeled at in the aftermarket. The Injector Dynamics 1000 marked the beginning of a new era in fuel injector performance; the ID 1000 was actually the first product from Injector Dynamics offering a number of top-notch features and available in dead time matched sets. injector dead times
