PEAK & HOLD 4A/1A DRIVER

FEATURES Current control driver for low impedance injectors 4 channels Available in three current versions: 8A/2A 4A/1A  2A/0.5A TECHNICAL DESCRIPTION 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) 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 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 (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.
