Fueltech - PEAK & HOLD 8A/2A DRIVER w/ Harness

Peak and Hold 8A/2A

• Controls up to 4 injectors with impedance below 1.5 ohm
• 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)
• Current control driver for low impedance injectors
• 4 channels

TO DETERMINE WHICH PEAK & HOLD YOU NEED

1. Grab a multi-meter and select Ohms 200
2. Touch the positive and negative leads of multi-meter together to measure resistance (record this number...i.e. measured 0.3)
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
4. 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 (Billet Atomizer*).
All low impedance Billet Atomizer Injectors manufactured after Nov. 2012 require 8A regardless of measured resistance.

*Billet Atomizer Injectors - Anything prior to serial # C300**** should only use the 4A/1A. This only applies to injectors manufactured prior to Nov. 2012.
