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 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.   CONTENTS OF PACKAGING   1 Peak and Hold 8A/2A 1 Operation and installation guide 1 mounting kit (4 rubber mounts, 4 washers and 4 ¼” nuts) 6ft Peak and Hold unterminated harness (optional) 1 FuelTech black carbon fiber sticker
