Low impedance injectors ms3x assembly instructions

A low-impedance injector (aka peak-and-hold) uses low-resistance coils that only need in the ballpark of 2-3 ohms, but needs higher current levels to operate. Re: High vs Low Impedance Injectors This is more of a question as to what drive stage you have connected to the injectors, and with the stock Low-impedance injectors (< 3 Ohms) can flow up to 15 Amps if not limited, and this will burn them up. Enter your injector resistance in ohms, your hold current in amps, as well as your injector impedance in ohms, in the form below and press the "Compute resistor" button. I have heard that the 50 lb MSD (high impedance injectors) suck for boosted applications because they tend to lock under high fp. I have a set of 50# injectors and they do NOT suck for boosted apps.. I ran them at 60psi without problems. Anyone tried modifing the obd1 pcm to drive low impedance injectors??? I know their is a convertor box, which I own one, but I would like to simplify the process, by just simply modding the pcm drivers. I know the ECM for the Grand Nationals can 1 MS2/V3. Hardware Manual Megasquirt-2 Product Range MS2/Extra 3.3.x Dated: Hardware Low impedance injectors - Injector Resistors This method has been used by many OEMs as a simple See the generic instructions in section 5.2 and Most engines of this era run coil-on-plug ignition It is not recommended to run low impedance injectors directly off the factory LS1 PCM. Another more cost effective option is to use a resistor pack. Resistor packs are common as OE items in many imports. Needed when using low impedance injectors (such as DSM injectors). Gold anodized finish with solder lugs. 3 ohms is the minimum required to where you shouldn't damage the injector drivers in the MS. It all depends on how much current you feel comfortable running However, because Low Impedance injectors, have a lower resistance, they draw more amps. More amps equals more heat which our PCM's drivers are not Low Impedance (ohm) injector (this is from the test of the 1550 cc ones I have), if plugged into a high impedance harness without a resistor box Peak & hold injector outputs (Programmable 4:1 or 8:2) Saturated injector outputs. Low impedance injectors supported. The ultimate in engine s. powertrain control. Www.ampefi.com. FACEB00K.com/MS3PRO. Most LOW IMPEDANCE injectors are engineered to "SNAP" open with more current than a HIGH IMPEDANCE" injector. The faster they snap open faster because of less resistance in the coil, hence they are more controllable. Generally, the more horsepower you have, the more you need the peak I have no more specifications apart from the injector impedance (around 2ohms) and the injectors must be driven by MOSFET. As this drive circuit is part of a ECU, the power supply must be more or less controlled in terms of power consumption. I have a question: is possible to decrease the time The ECU supports both high and low impedance injectors, hence why i didn't think much of using different injectors on the sister car. Would the difference in high/low impedance make the actual injector open/close time (at the nozzle) different, if the signal pulse width from the ECU is the same The ECU supports both high and low impedance injectors, hence why i didn't think much of using different injectors on the sister car. Would the difference in high/low impedance make the actual injector open/close time (at the nozzle) different, if the signal pulse width from the ECU is the same Low Impedance Injector control with Programmable Injector Peak and Hold Currents. Closed Loop O2 Control - for precise tuning (With optional external CAN 16x BIG 10amp injector drivers that can run 2x Moran/Siemens Deka/Precision low impedance injectors per driver directly from the ECU (no Low impedance injectors with a resistance of 0.5-6 ohms, and high impedance injectors of 6 to 12 ohms. ECUs that use Saturation signal require an external dropping resistor when used with low-impedance injectors. This includes most factory ECUs.
