Just when you think a product can't get better it does. Two new controllers from FuelTech USA with there new High Voltage Injector Driver and the new GEN3 FT Spark. Its a constant battle to control massive port fuel injectors due to there mechanical "laziness". The new HV Driver can drive the 820 and 1020 injectors very close to a high impedance injector mannerism. This same driver also can run the high amperage style injectors used for Direct Injection engines. The GEN3 FT Spark is focused on igniting all the fuel in the chamber on ultra high performance engines where cylinder pressures are very high and a cylinder loaded with alcohol. More in the article!
