HI, I have started my first PCB today to make a BOB from a speeduino V0.4 to a 97 miata stock ecu harness. I no experience with speeduino or other ECU. I have a basic knowledge of electronics and programming. Here's my electronic schematic for the connectors. the 4 pins one is for the wideband.
My questions.
Is it a good idea to use an existent plug and wire to do boost control (ex: use EGR plug to connect boost solenoid)?
Do the chassis ground and sensors ground go to the ground plane on the PCB?
On what pin do a put the VSS?
Do the Water Meth Injection take the VVT output?
Is it ok to take the 12v for the wideband there or it is best to take another source?
1997 miata connector for reference
