Is there a device that allows all of the ECM's values to remain even when the battery dies or is disconnected?

Casper's? THX

Hmm, excellent question... Maybe like a 9volt battery that can be plugged in somewhere?? I would like to know this also. This would be great especially for the MaxEffort.

thought you were talking about the six million dollar man for a moment....

not sure if nine volts is enuf or not but I am sure a prom guru can say. Would be easy to rig a harness to do it off the ecm wire.

Once you have your programming down the way you want it, you can get Steve to blow you a chip with your settings a defaults.

9v might be too much. Most of the bats in industrial controllers use 3.2v lithium that is the same size as a AA.

AS a matter of clarification for those of you with good imaginations, Stinky is his cat!

Cappy, try this site:

Product #25036 9V COMPUTER MEMORY SAVER

I've never used it - just passing the info along.

Huh?? The ECM is supplied (on all it's voltage inputs) with 12v battery voltage. It's stepped down internally across zeners to get the needed 5v levels internally. IMHO a 9v battery should suffice on the one input that supplies the static ram chips, only question then would be, would it last long enough.

I have seen a small device that plugs into the cig liter, that is made to keep your computer codes and radio setup. It plugs into the lighter. I think it uses a 9V battery

Why not keep it simple and safe?
Just get a low current relay that switches the ECM load to an alarm gel cel battery, 7-12 AHrs., once power is removed from the relay, meaning the battery dies or is removed.
Feed the gel cel a little alternator current from a wire wound 250 ohm resistor and you're done.

Would be a good way to keep power to an aftermarket alarm as well.

Problem with that is, you now have introduced a mechanically switched device that depends on the sensing of a loss of voltage to trigger, right?
Keep in mind in only takes a few microseconds to dump the ECM's ram, and the relay can't posibly react fast enough.

Toady & Dave C, thanks I'll check it out.

Salvage's idea could work like the "Computer Memory Saver" if you switched it on before disconnecting the battery. Maybe a low voltage sensor switch might trigger it on before the main battery goes dead?

"Build it and they will come!.
