Hi, I've been looking to buy an aftermarket ECU for a Toyota 3RZ-FE (direct spark) engine and it looks like the G4+ Atom is perfect for my application, I was originally going to go with a Microtech lt9c but their email support was shocking and I'm glad they didn't respond now because I have discovered the G4+ Atom. Anyway back to my question I am planning on buying an Innovate SCG-1 for it so I can monitor my AFR and have closed loop boost control and the SCG-1 seems to kill 2 birds with 1 stone at a very affordable price. I'm not very switched on when it comes to engine management systems so you will have to bear with me. Can I wire up the SCG-1 wideband o2 output into the ECU so the it knows the AFR? Can the ECU control boost using the SCG-1 boost solenoid or will I need to let the gauge do that itself? What are the 2 Digital Inputs? It said "vehicle speed and logging switch" on the page, What sensor is needed to find out the vehicle speed or if I need to route the aftermarket speedo gauge through the ECU would that use one of my Auxiliary Outputs to get it to the speedometer gauge? With the 3 Analog inputs I would be running a map sensor, wideband o2 sensor and for the 3rd input what would be the most useful? Throttle Position? If I was to use one of the auxiliary outputs for a thermo fan switch would I need to run an additional temp sensor to the radiator as the engine temp sensor is threaded into the engine block? Thanks in advance!
