Innovate LC1 - Serial Input with Ectune.

I wired the Blue And White Together, and ran them to the thermostat Housing Ground.
Power, wrapped wire arround a fuse leg, 10am, and plugged it in.

IS that okay

I don’t know it this helps but I did find a lot of eld info in the books. I have not had time to play with my transistor thing yet. https://www.homemadeturbo.com/forum/...topic=100718.0
I have no clue if the alt disables at wot? Sounds logical but I have not played around yet. Said under 3500 so maybe not.

Wot is when you really don't want a sudden voltage drop messing with sensors readings. If I were designing my own ecu to run an engine I wouldn't want the car running off the battery at wide open throttle.

No offense, but if you were designing an ECU you would use voltage regulators to provide a steady 5V input to your sensors regardless of Battery Voltage. It would be a non issue.

Have you ever tried to tune a car with a dying alternator. it's no fun. especially when trying get injector battery offsets to play nice.
I'm not an all knowing guy or anything but Ive fooled around with a lot of cars and I know that when an alternator isn't charging it has an imidiate affect on the car. voltage dips at wot can even mess with wideband readings.

True, and that's why the inj battery offsets are important. Injectors aren't under 5V regulators. they get as much voltage as possible to maximize effeciency.
