FuelTech’s Peak & Hold 8A/2A Injector Driver is a 4-channel low impedance driver unit that controls up to 4 injectors with impedance below 1.5 ohm. Designed for use with low impedance fuel injectors. Mounting kit included.

Technical Description

Controls up to 4 injectors with impedance below 1.5 ohm

4 FT Injectors (1 per channel)

16 Bosch 160lb/h (1600cc) injectors (4 per channel)

8 Siemens low impedance injectors (2 per channel)

4 MSD low impedance injectors (2 per channel) (with 2 ohms impedance per injector)

To determine which Peak & Hold you need

Grab a multi-meter and select Ohms 200

Touch the positive and negative leads of multi-meter together to measure resistance (record this number...i.e. measured 0.3)

Then take the positive and negative leads from multi-meter and put on each terminal of the injector. Doesn't matter the order. Record this measurement

Take the ohms measurement from Step 3 and then subtract the number you got in Step 2 (i.e. Step 3 4.8ohms - Step 2 0.3ohms = Total 4.5ohms)

High Impedance Injectors - Above 7ohms - No Peak and Hold Boxes are needed.

Peak and Hold 2A - 3ohms to 7ohms (Bosch 160lb/hr).

Peak and Hold 4A - Below 3ohms to 1.5ohms.

Peak and Hold 8A - Below 1.5ohms (FT Injector, Billet Atomizer*).

All low impedance Billet Atomizer Injectors manufactured after Nov. 2012 require 8A regardless of measured resistance.
