The first thing to know about the FuelTech PowerFT (FT450, FT550, FT600) line-up! Unlike many other manufacturers, the ECU's all use the same software. They also all have the same features within the software like extremely effective traction control, built-in accelerometer(G-meter), gyroscope, ect. We do recommend to avoid using the FT450 on V8 applications due to input and output amounts, so we will only be comparing FT550 vs FT600 from here out.
The basic differences in the FT550 vs FT600. The FT550 has a very durable and IP67 rated ABS case, the FT600 has an IP67 rated rigid aluminum case. The FT600 has a slightly larger screen, as well as overall dimension, and LED's on the perimeter that can by used to signal when something is active, a shift light, ect. The FT550 and FT600 both can be set for the entire screen to flash a color for a shift light.
The difference that will most likely determine the ECU for you. Inputs and Outputs.... FuelTech doesn't have dedicated inputs and outputs that can't be changed or reassigned like many other manufacturers. With that being said, the total amount listed for each ECU is the total including what most assume are common like water temp, intake air temp, throttle position, injectors, coils, ect. So let's break this down into examples.
Now, before you get upset about no IAC.... Yes, FuelTech will control it, and yes it works well. But.... GM IAC valves use 4 outputs. When the throttle set screw is set correctly, and with FuelTech's spark idle control, VERY rarely is there a significant compromise for idle control. More times than not, Idle control ends up better than other ECUs using an IAC and spark control combined, so why waste 4 outputs to control it? We have yet to run into a scenario where we have needed to add an IAC to any combo's we have set up.
What about drive by wire/electronic throttle? Yes, FuelTech FT550 and FT600 both will handle that. It will require using 2 inputs and 2 outputs.
Sooooo.... Which ECU fits your build/mindset best? Most people that have made it this far have realized the FT550 has enough to do everything they currently want, and still have room to grow. If you need more inputs, an Input Expander is available. If you decide to upgrade from an FT550 to FT600 later, you can purchase a plug-and-play adaptor harness, or you can purchase the FT600 connector kit and re-pin the harness accordingly. If you want to jump straight into shock sensors on all 4 corners, front and rear wheel speed, utilizing a FT CAN switch panel, ect, then an FT600 is where you need to look.
