Peak and Hold 4A/1A

• Controls up to 4 injectors with 1.5 to 3 ohms of impedance
• 8 Bosch 160lb/h (1600cc) injectors (2 per channel)
• 4 Siemens 83lb/h injectors
• 4 MSD injectors (with 2 ohms impedance per injector)

Peak and Hold 2A/0.5A

• Controls up to 4 injectors with 3 to 7 ohms of impedance
• 4 Bosch 160lb/h (1600cc) injectors

Dimensions: 115 x 90 x 33mm

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 (FT Injector, 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.
