Peak and Hold 8A/2A

• Description
• Downloads

• 4-channel low impedance injector drive driver.
• Peak and Hold Manual

Characteristics

• Current control driver for low impedance injectors
• 4 channels
• Available in three current versions per channel:
  8A/2A
  4A/1A
  2A/0.5A

Technical description

• Controls up to 4 injectors with impedance below 1.5 ohm
• 16 Bosch 160 lb/h (1600 cc) injectors (4 per channel)
• 8 Siemens low impedance injectors (2 per channel) - 83lb/h, 225lb/h
• 4 MSD low impedance injectors (2 per channel) (with 2 ohms impedance per injector)
• 4 Precision, Moran or Billet Atomizer injectors

• Controls up to 4 injectors with 1.5 to 3 ohms impedance
• 4 Siemens injectors 83lb/h, 225lb/h
• 4 Siemens Trick Flow injectors
• 4 MSD injectors (with 2 ohms impedance per injector)
• 8 Bosch 160 lb/h (1600 cc) injectors (2 per channel)

• Each output can drive an injector with an impedance above 3 ohms (Bosch Nozzles 160lb/h)

You can use as many outputs as necessary without compromising the other outputs, that is, the module can control 1 to 4 injectors

Dimensions: 115 x 90 x 33mm

To choose which Peak Hold you need

1. Use a multimeter on the resistance scale (Ohms) and select the 200 Ohms scale
2. Touch the tips (red and black) together and check the value displayed on the multimeter, example: that is, measured 0.3). Resistance
3. Then, take the multimeter tips and place them on each injector terminal. The order doesn't matter. Record this measurement
4. Take the ohms measurement from step 3 and then subtract the number you got in step 2 (Step 3: 4.8ohms - Step 2: 0.3ohms = Total 4.5ohms).

High Impedance Injectors - Above 7Ohms - No Peak and Hold required.
Peak and Hold 2A - Injectors with resistance between 3 and 7 Ohms (Bosch 160lb/hr).
Peak and Hold 4A - Injectors with resistance between 3 and 1.5 Ohms
Peak and Hold 8A - Injectors below 1.5 Ohms (Billet Atomizer*).
All low impedance Atomizer injectors manufactured after November 2012 require Peak and Hold 8A regardless of measured resistance.
