FuelTech Peak & Hold 4A/1A Injector Driver - 3010003324
Optimized Control for Low Impedance Injectors
The FuelTech Peak & Hold 4A/1A Injector Driver is engineered to deliver precise current control for low impedance fuel injectors. Featuring a 4-channel design, this unit controls up to four injectors with impedance between 1.5 to 3 ohms, making it ideal for high-performance and racing applications requiring accurate fuel delivery.
By managing injector current during both peak and hold phases, this driver improves injector response, ensures consistent operation, and enhances overall fuel system reliability under demanding conditions.
Designed for 1.5-3 Ohm Injector Applications
This 4A/1A version is specifically calibrated for injectors within the 1.5 to 3 ohm range, ensuring proper current delivery without overheating or damaging components.
- Controls up to 4 injectors
- Designed for 1.5 to 3 ohm impedance injectors
- Supports Bosch 160 lb/hr (1600cc) injectors (2 per channel)
- Compatible with Siemens 83 lb/hr injectors
- Compatible with MSD injectors (2 ohm impedance, 2 per channel)
Multiple Options for Different Injector Setups
FuelTech offers three Peak & Hold driver configurations to match specific injector impedance ranges. Choosing the correct version ensures optimal performance and system reliability.
- 8A/2A - For injectors below 1.5 ohm
- 4A/1A - For 1.5 to 3 ohm injectors
- 2A/0.5A - For 3 to 7 ohm injectors
How to Determine the Correct Driver
To select the correct Peak & Hold driver, measure injector resistance using a multimeter:
- Set multimeter to Ohms (200 range)
- Measure lead resistance and record value
- Measure injector terminal resistance
- Subtract lead resistance from injector reading to determine actual impedance
- Above 7 ohms - No driver required
- 3 to 7 ohms - Use 2A/0.5A driver
- 1.5 to 3 ohms - Use 4A/1A driver
- Below 1.5 ohms - Use 8A/2A driver
Important: Billet Atomizer injectors manufactured after November 2012 require the 8A driver regardless of measured resistance. Units prior to serial # C300**** should use the 4A/1A version.

FAQs
What injectors is this driver designed for?
This driver is designed for low impedance injectors with 1.5 to 3 ohms resistance, including Bosch, Siemens, and MSD injectors within that range.
Do I need this if I have high impedance injectors?
No. High impedance injectors (above 7 ohms) do not require a Peak & Hold driver.
