Injector open time
Webb3 nov. 2011 · As for the values when FP rises wtih boost, no worries, that's what your pulsewidth takes care of, like i siad, most older systems and some newer ones don't even call it dead time, it's just voltage compensation mapping and in boost you have higher bolts at higher RPM's (at least your regulated peak of say 13.6) and dead times don't make a … http://siriuscyber.net/sharktuner/Determining_Injector_Opening.pdf

Webb31 maj 2016 · (In my case, injector opening time is likely ~0.8ms but the effective deadtime is 0.3ms) But anyway, I tested my second set of injectors. Since I already had the excel sheet setup it took just a smidge over 2 hours to establish:-deadtimes, -minimum opening time -CC rating and inner/outer injector ratio-Short pulsewidth adder table. Webbstrength of the injector by 60%, resulting in huge improvements in the capacity, range, and opening time performance of the injectors.

Webb30 nov. 2024 · fitech uses opening time which is basically the same as what holley calls their off time voltage offset. If you have the same injectors as said user subtract 1200 from all offset values and then divide by 1000. this gives you your holley off time value. Webb4 juni 2024 · Min Injector Opening Time 1.5 ms Driver Setup 8:2 etc. When you go "back" and select Injection type multi-port or TBI, whatever was configured previously on that page for injector set is changed to High Impedance, 9999.9 lb/hr, 999.9 psi. This seems to cause problems syncing the custom config with the ECU which requires low impedance …
Webb9 aug. 2024 · The transformation of a standard 4-stroke cylinder head into a torque-improved and gradually more efficient 2-stroke design is discussed. The concept with an effective loop scavenging via an extended inlet valve holds promise for engines at low- to medium-rotational speeds for typical designs of conventional 4-stroke cylinder heads. … WebbLet's say that we need two milliseconds of injector opening time to achieve an air/fuel ratio of 14.7:1, and the injector has a dead time of one millisecond at 14 volts. 04:31 If we have an ECU that is correctly accounting for dead time, the ECU will provide a pulsewidth of three milliseconds.

Ok, now that these have been checked (and fixed, if they’re not working), it’s time to dial in the startup fueling.

Overrun Fuel Cut Delay This is the delay between overrun conditions being met (throttle closed, rpm over about 1800 rpm) and the injectors shutting off. A long delay gives 'rev hang' effects.

When manifold depression is low (Fig.2.2A), fuel pressure needs to be high to ensure sufficient fuel is forced through the injector for a given injector 'open time', say 0.003 cc of fuel per 10 millisecond period. When manifold depression is high (Fig.2.2B), the depression will try to 'suck' fuel from the injector nozzle. mango color paletteWebb10 juli 2012 · Unless one has some very fancy injectors.
