This should probably be in another forum but we can lay this one down to rest most likely after 1 response.

I have my ecu dynoflashed. If I disconnect the battery, the dynoflash isnt erased from the ecu's memory is it?

Thanks

 

No.

 

Nope - reflashes are 'burned' in. It'll be there until you get another flash to overwrite it. Think of it like an operating system on your computer. You turn it off, but it's still there.

 

It's on the hard drive and not in the RAM.

 

Nope...your DynoFlash is in non-volatile memory...it stays intact even when the power is removed. The "learning" part of the ECU (fuel trim and all that) will be reset when you disconnect the battery, but not the flash itself.

 

There are no stupid question and as people has stated above your flash is hard coded in the ECU and will not be erased due to battery power being disconnected.

 

There are no stupid questions only stupid people.

 

Actually it is more similar to the bios on your pc. Just as you reflash your bios on your pc, reflashing the ecu is very similar. It is on ROM, not RAM, not hard drive.

 

Yeah but which analogy is easier to understand to the layman? Not everyone knows what the BIOS is, granted, this guy might, but still. Everyone who has a computer understands "hard drive". I figured the part in question would be RAM. I go by concept understanding as that is all you really need to know (in these cases).

 

Hey thanks everyone, It seems I have plenty of responses so its safe to say I have no worries then.

 

If you could lose the reflashed map like that, you could also lose the stock map like that.

How do you like a car that fries the ECU every time the battery dies?

 

Not the greatest analogy. Most people have had the experience of having a hard drive crash due to a mechanical failure. When I think of a hard drive I think of something that will inevitably go bad and die. This is much less likely to happen with solid-state storage such as flash ROM.

 

Oh Lord. Nevermind. You are one of those people that gets WAY too into something and distorts the meaning aren't you? I am not even coming close to referring to reliability comparisons between different means of storage. I am simply talking about method of storage. People know that stuff on their hard drive stays when they turn off the computer. People, in general, except for geniuses like us, do not understand the difference between ROM and RAM. KISS.

 

wow...what are you guys talking about...i'm lost...i must be dumb...

 

Hey, I understand the difference between ROM and RAM

That's some new hip pop band, right?
