WebbAt 6000 rpm it takes 20 ms for two revolutions. If a fuel injector is activated for 15 ms (the IPW) at 3000 rpm the duty cycle is 37.5% (15 ms/40 ms), or rpm times IPW divided by 1200 equals IDC in percent. If an injector is powered for 15 ms at 6000 rpm, then IDC is 75% (15 ms/20 ms). WebbGetting it tuned. Ok, now that these have been checked (and fixed, if they’re not working), it’s time to dial in the startup fueling. All MegaSquirts use the following sequence for fuel during startup: When the key is on, the MegaSquirt will turn the fuel pump on for 2 seconds and fire one priming pulse to clear air for the lines.

Webb6 mars 2011 · Total Cats: 84. Big injectors need accurate dead-time numbers, because the flow is dependent on the difference of 2 large numbers. For example. Assume 1.0 ms dead-time for both big and small injectors below. A wee injector may need 0.9 us of fuel delivery at idle. So electrical pulse must be 1.9 ms. Webb29 nov. 2014 · That is why bypass air is the biggest enemy of every injection. The ECU calculates out of all possible engine states an injector opening time (about 1 to 10 milli-seconds) and opens injectors of respective injector group together.

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. http://www.mrm-racing.se/forum/forum/public-forums/autronic-support-software-downloads/autronic-support-forum/416-injector-end-angle-calculation

WebbInjector opening-time is one of those variables that effects everything (except cranking). Injector opening-time (aka dead time, latency, offset, etc) varies greatly with the various injectors that are available, and if not correct then the actual fuel that is injected will differ from what the LH calculated. 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 …

WebbNormally the injector manufacturer will supply injector opening time figures. 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.
