Web4 jun. 2013 · MalcolmV8. My trick was to replace them with ID 1000s. Those 80s suck. You can get the 80s to work better though by using the minimum pulse width values from the 60 lb injector value files. I think that was the main thing SCT had me tweak. Search the SCT PRP forum, lots of discussion on this issue. Web25 nov. 2006 · Greenlight (Mechanical) 20 Sep 06 00:36. Here's a basic formula: 84,000 / tuned rpm = runner length. The runner length is measured from the back of the intake valve to the start of the radiused entry of the runner. Most people use the max. torque rpm as the "tuned rpm". clearwater aquarium coupon code

Web3 nov. 2011 · The "dead time" value in Link is not telling the ECU how much latency the injectors have so that it can compensate for it...it's a value that gets added directly to the pulse width. So instead of telling the ECU "My injectors have this much latency, so deal with it", it's actually telling the ECU "Add this much time to the injector pulse widths." WebSpace Vector Pulse Width Modulation (SVPWM) is animproved technique for generating a fundamental sine wave that provides a higher voltage to the motor; lower total harmonic distortion, and controls the number of short pulses in the PWM waveform.

WebThe "Fuel load" to "pulse width calculation" uses many factors like engine displacement, fuel type and injector flow. The injector dead time is also added to the pulse width calculation. All of these are pretty much constants so the "fuel load" to "pulse width" relationship is almost linear. WebThe injector opening ramp is not a flat line. It is actually a curve. This makes it difficult to guess. The injector closing ramp is also a curve. Same as above, difficult to guess; This all changes with the voltage applied to the injector. This adds another table dimension to cover for changing battery voltage, and this does have a massive effect.
