Switched from the stock low impedance to 750 cc high impedance injectors. Peak and Hold PRO Injector Driver is an advanced module designed to control low impedance injectors at a professional level, featuring 8 channels, 26-way automotive connector and several motor protections levels in case an injector or connection fails. AEM’s Peak & Hold Injector Driver contains 10 independent injector drive channels. Because the injector current is reduced twice the voltage has two backwards spikes rather than one. Note the following specifics: Number of Injector Sets – Enter 3 (even though using 2). Oct 9, 2012 · High-impedance injectors, also called saturated fuel injectors, are sent a 11-1/2-amp current signal to open, and that current stays on until the injector closes. 01:02: This refers to the way in which the ECU needs to control the injector. Jan 11, 2012 · OP, you said you have to build "a low impedance driver" and repeated in a subsequent post that you need to reduce power dissipation. Aug 26, 2018 · Still ran great so I went to the next upgrade, bigger injectors. Mar 27, 2002 · I already know that the n/a uses high impedance injectors and the tt uses low impedance. For those unaware the low impedance fuel injector features an internal coil resistance of less than 7 Ohms while high impedance injectors are greater than 7 Ohms. The Peak&Hold Injector Driver Board v2. See full list on injector-rehab. The high impedance injectors can use either a saturated or p/h driver. 02:37: It is possible to run a low impedance injector from a saturated injector drive by adding some resistance to the injector circuit. ECU COMPATIBILITY: May be used with any ECU currently on the market. These FuelTech Peak and Hold PRO injector drivers are advanced modules designed to control low impedance injectors at a professional level, featuring 8 channels, 26-way automotive connector and several motor protections levels in case an injector or connection fails.

LOW IMPEDANCE: Available in 320 lb/h, 520lb/h, 720 lb/h, and 820 lb/h. AEM’s external Peak & Hold Injector Driver module allows ECU’s that have a saturated injector drive circuit to trigger low impedance injectors with a true 4/1 Peak & Hold injector drive circuit. The following is how the software should be set up. If that's the case, you need to use a Pulse Width Modulated (PWM) output injector driver. FuelTech’s Peak & Hold 4A/1A Injector Driver is a 4-channel low impedance driver unit that controls up to 4 injectors with impedance between 1. 01:06: The saturated drive style is the simpler of the two and doesn't require any real sophistication on the part of Low impedance injectors or peak-and-hold drivers involve high-pressure fuel pressure and a large injector, allowing more current to flow across the injector with utmost consistency. Peak & Hold external driver required for low impedance fuel injectors. Description FEATURES. Mounting kit included. What is the difference between a high-impedance and low-impedance injector? Low impedance injectors, on the other hand, use what’s called a peak-and-hold driver. “There’s really no specific advantage between the two,” confirms Lunsford. The circuit driver can regulate current from 4-10 amps to open the injector. Peak & Hold PRO Injector Driver by Fueltech 8-channel low impedance injector driver, features protections and diagnostics, CAN communication, and configurable current via software. [/B/] Research revealed that some of the 91-92 tt and n/a used the same ecu, and possibly the same p/h driver. Enter the “Duty Cycle Activation”. Nov 30, 2012 · SymTech Labs’ PH Driver board is a small, integrated package that contains four peak-and-hold drivers – one for each injector. Designed for use with low impedance fuel injectors. The board has its own 5V power supply, which means it is powered by 12V, and is designed to be installed in its own case. The injector current rises to 4 Amps to open the injector quickly, then is reduced to 1 Amp to hold the injector open. Duty cycle of the first set, at which the second set is started to ramp in. Features: Four channel injector driver with activation input. com Peak and Hold PRO Injector Driver is an advanced module designed to control low impedance injectors at a professional level, featuring 8 channels, 26-way automotive connector and several motor protections levels in case an injector or connection fails. Because the n/a Low impedance injector driven by the Hondata Injector Driver. “A low-impedance injector driver normally has more amperage capability and costs more. Mar 5, 2024 · Complementing the FT Injector line of low impedance fuel injectors are FuelTech's Peak & Hold Drivers, sophisticated electronic modules designed to enhance injector performance and compatibility. FuelTech's 320 lb/h, 520 lb/h, 720 lb/h, and 820 lb/h fuel injectors require a peak and hold driver, we recommend our 8A/2A Peak and Hold Driver or our Peak and Hold PRO Injector Driver, and are compatible with any ECU currently on the market. The main concern is that the ECU injector driver outputs will be damaged as they are not designed for the amount of current a low impedance injector draws. Low impedance injectors draw more current than high impedance injectors and will eventually overheat if the injector driver output does not limit the current. Jan 1, 2006 · If you put the low impedance injectors in the car you will most likely damage the injector drivers in the PCM, as they were never designed for such a high current. FuelTech Peak and Hold Low-Impedance fuel injector drive units help provide more consistent voltage on fuel injectors with low resistance, which are more sensitive to battery voltage changes. 5 to three ohms. Both sets of injectors need to be high impedance or low impedance. 02:45 HIGH IMPEDANCE: Available in 80 lb/h, 120 lb/h, 170 lb/h, and 240 lb/h. 5 to 3 ohms. High Impedance injectors usually measure 10-14 ohms. Peak-and-hold (P&H) drivers are “smart” devices that implement an active feedback loop to monitor and adjust current through most low impedance fuel injectors. . These boxes help maintain proper fuel delivery, maximizing performance.
