Hey Whats up people,

I'm just curious, I have the Digital Dakota box because I have a 700R4 (temporarily) in a thirdgen firebird which has an LT1 engine, along with the dash swap so it has LT1 cluster. I'm going to use the Digital Dakota Box just to get everything running correctly, however I am a bit curious about something.

Once you calibrate the box with the correct coarse/fine settings, how does it remember? From what it says, it gets power via ACC wire. So there is no power to is when the car is off. Is there some type of a tiny battery inside? I'm just curious how it retains the settings.

Anybody know for sure?

 

its funny you mention,I don't know exactly how that works either.
I just put a blaupunkt radio in my car that has the cd naming function.
I took this radio out of one of my old cars about 5or6 years ago and had it lying around so I figured I'd stuff in my current project car.
Got it all hooked up and it still has all the cd names I originally programmed into it 5+years ago!??

 

When you calibrate the unit, you determine a cal ratio ( measured value/indicated value). they you look the cal ratio up in the table on page 7 of the tech manual and set the switch positions accordingly. The switch positions are the memory for the calibration settings.

When you turn the unit on its computer reads the switch positions and uses them to determine the calibration ratio for each function. The switch positions effectively serve as an address into a look up table to find the cal ratio. The switch positions are a binary code for the table address for the cal value.

Since the unit uses the switch positions to hold the information, it is never lost unless the switch positions are changed.

Hope this expatiation is not to complicated

Your CD player likely has a erasable electrically programmable memory chip to retain the CD titles. It does not lose the information when the power is turned off. Since it is erasable you can over write an existing title.
