TECHNICAL DESCRIPTION

Peak and Hold 4A/1A

  • 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)

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 (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.
