Minimum injector pulse reached chevy. Zero delivers zero fuel. This Minimum Injector PW: Minimum allowed Injector Pulse Width (after Short Pulse adder has been added if necessary). Current will flow Exactly. Currently I'm unable to target stoich at idle because sudden off throttle demands an injector pulse that is below what my injectors We can test specific fuel pumps, regulators, injectors and set fuel pressures to meet the particular requirement. If you have the latest style injectors the minimum pulse width is much lower on them The ECM/PCM calculates the proper injector pulse width and then compares it to the minimum pulse width. 4 m/s at idle in The injectors are synchronized to the rotation of the engine by the DRPs (Distributor Reference Pulses) and they will not fire if the ECM doesn't see those DRPs. 6ms (60lbs). How would I input this setting? I am using a 07 c6 short pulse adder table and minimum pulse width table also and this combo seems to be working well so far. It then uses whichever is LARGER. Your scan tool should be seeing the injector C4 Tech/Performance - What is Too Low of a Duty Cycle for Injectors? - Long story short: I built engine for forced induction, bought injectors for lots of hp and I suspected the injectors were clogged, resulting in the ECU turning them on longer to compensate. I am using a basically stock Maf hi and lo transfer table also with minimal scaling. Say you were to put a larger size inj in and tried to force it to idle lean commanding a pulse width less than what said injector can handle ? What would you see ? Inj refuse to fire ? Do you see references to the low pulse width performance of a fuel injector and wonder what it means? Do you wonder how it relates to the real-world . Pintel style has the slowest rate as they have more mass to move. 4ms then back up to 2. 5ms most of the time. That would be both in Drive and Park. 0 m/s at idle in Drive and 3. Minimum injector pulse width is the shortest injector on-time that reliably produces fuel flow. What that boils down to is that if you put in giant injectors I moved the injector flow rate back to where they were supposed to be and noticed that the minimum pulse width the PCM would ever command was around 2. Currently I'm unable to target stoich at idle because sudden off throttle demands an injector pulse that is below what my injectors can The fuel injector pulse will be our topic for today, and we will mention some fixes that might help you should you encounter this problem. Every injector has a minimum pulse width. Below this threshold, the injector may open inconsistently, deliver unpredictable fuel, or not flow at all. So at idle and and light throttles it Can anyone tell me what their Injector Pulse Width is at idle? This would apply to L36 engines only. The PCM uses this data to Not sure what the context of your question is but there will always be a minimum "reliable" pulse width of an injector to deliver fuel. Thanks I'm having some trouble with injector minimum pulse width. P01 411 ecu, lq9, ID850's, turbo in a 69 C10. I'm running an LS1 on COS3 and adjusted the pulse width down accordingly (in terms that I understand B9021 removes a hidden "mimimum" PW that you run into), I'm also running SD60's and had the When the injector is to be actuated, the engine control module connects the negative side of the winding to ground through a transistor. 5. I'm having some trouble with injector minimum pulse width. Nothing in between. So I proceeded to remove them and bench clean each injector with brake cleaner and tapping the pins to It would be nice if we had a minimum injector pulsewidth calibration. Hypothetical what if. The various tables (offset, flow rate, and low pulse adders) provide a mathematical model of the fuel injectors dynamic response. If I know my fuel injector is only linear down to say 2. Making it difficult to Quick question: my injector data sheet has a minimum effective pulse width, but I can’t seem to find anything in Haltech regarding this setting, even for elite ECUs. 319ms. Mine are running about 4. If it does it drops straight down to 1. We also simulate temperature changes in the engine as well as the inlet air temperatures. Default Injector PW: Default Pulse width used when Injector Pulse Width is less than I recently fitted 60lbs injectors to a factory stock car (exhaust and intake only) with an outcome of reducing the idle pulsewidth from 2. 00ms, I would like to not run below that to help with idle stability. Most of it has to do with the time it It is the flow we are concerned with, not the pulse width, and if we are fitting large injectors to a small engine it is the minimum amount of fuel that the injector can Would the injectors not respond to a pulse less than a certain width? It takes time for a valve to open and close, if the pulse wasn't long enough, the valve may not have time to respond. Pulse width will not drop below 2. 8ms (factory) to 1.
