Seperate Battery Power for RAM from DB37?

Post by chevelle »

Would there be a way to build the v3.0 board so that a separate pin on the DB37 supplies power to the RAM only?

That way you could put constant battery power on that pin and set AMC to RAM Update only and not lose your new fuel table in ram when you turn the engine off. Then if the table gets messed up by a faulty 02 sensor or whatever all you need to do is unhook the battery to reset to your original fuel table saved in FLASH, just like a factory OEM ECU. Let me know what you think about that and if it's possible. Thanks.

The processor RAM itself cannot be powered independently of the rest of the processor.
