There is a math calculation to convert to and from but I'm too lazy to google. your scalar value is now present in the field box for injector scalar. This will display it in µs, enter in the value you got from the spreadsheet and then select default again. benefits of workflow dependencies alteryx uhaul cost calculator. Ideally most subaru systems see 13 to 14v constantly and consistently at ECU voltage, maybe 13.5 to 14.5 if with the diode mod.Īnd to convert IPW (µs) to scalar, go into a normal 16 bit MAF rom and select injector scalar, then hit the value selector, from default to RAW. These rough running symptoms can be traced to inefficient fuel injectors in that they. It is arguable if the bottom cell for 6.5v needs to be accurate or not, seeing as how we don't intend to run the vehicles on that low of a system voltage. We know 8 to 16 v, so interpolating here is fine but the ends which are 6.5 and 16.5 will have to be roughed out. 10 p1692 N67-20712 Approximate calculation of the dynamics electrons injector - buncher TTD - VT - 45-488 ) 10 P1693 N67-20717 Approximate calculations. The 32bit ecu values range from 8v to 16v, and 16bit ranges from 6.5v to 16.5. This is not just a size thing but injector size is the largest part of this setup in the ECU.Interpolation and a little bit of guessing Keep in mind, your tune must be set up for whatever injectors you choose. Use the max Duty Cycle from the spread sheet above for the Max RPM you plan to runĤ3.5 PSI Fuel Pressure as this is really the difference between your absolute pressure in the intake compared to the absolute pressure in the fuel rail. It works by estimating airflow based on a few known parameters, and then calculating fuel. You can use the formula RPM x MAP /5100 to get in the ballpark for HP.Įxample stock would be 165 KPA x 8050 RPM / 5100 = about 260 HPĪ big HP motor example 225 kpa *9100 / 5100 = about 400 HP The Injector Dynamics fuel flow calculator is not based on efficiency. The ID1300x is an all new injector, designed in partnership with Bosch. injector dynamics make a number of different injector sizes and styles that fit the bill. This is the DC that you feed into a calculator that you use in the RC Engineering calculator.Įstimate your crank HP. This sheet works by allowing the injector enough time to reset after the fueling event. As an example 8000 RPM gives 80% 9000 RPM gives 77.5% The typical calculator that you find on the net does not account for high reving motors. (Use the Fuel Injector Worksheet below to perform this calculation for you. Nominal Flow Rate 1065cc/min 3.0 Bar (43. Replaceable inlet filter extends service life. It must also be tested in an environment that simulates real world conditions as closely as possible. To learn anything of value about a fuel injector, it must be tested dynamically. It does not operate in a wide open or 'static' condition. Simply stated, a fuel injector is a dynamic device. Stronger magnetic circuit offers stable operation up to 10 bar. A Little Bit About the Injector Dynamics Technology. Here Is a calculator I put together for calcing the max allowable Duty Cycle of the injectors. Injector Dynamics Horsepower Calculator (1) - Free download as Excel Spreadsheet (.xls), PDF File (.pdf), Text File (.txt) or read online for free. Improved internal flow path increases output by 5 without sacrificing low flow performance.
