Thanks for the info, The Atom ecu doesn't have a CAN port does it? which means I would have to use analog. I did see a few posts on some websites about problems with the Innovate widebands but they all seemed to be from 3-6 years ago so i figured they must have improved them. Also what is the difference between the closed loop and open loop boost controllers? I thought that because it uses a solenoid to control the boost it can keep the wastegate shut until boost level is achieved so it makes full spool quicker.

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!
