Bad ECM + Death flash questions
Part number: 56040273AF

I have a bad ECU/ECM/PCM (whatever) now. My concern is that every website I look at for a new one has "Pre-programmed to your VIN# and mileage with the latest Chrysler updates" So this would imply that they're going to update it with the death flash right?

One person I spoke to told me that since I have the AF model they would give me the AG model, but that's one update up so I figure that's got the flash, he said to order the AD but that's a few updates behind what I have and I don't know if that's what I want either.

In a nutshell I need a new ECM but I need to know how to identify if it will have the death flash or not.

Do you absolutely have to have a new/rebuilt one?

I've been working in scrap yards for years and have sold quite a few used ones. Maybe a couple hundred and can't ever remember one coming back that I know I tested.

Check and see if you can locate one locally if you consider that an option.

You should be concerned with the AF when looking.

It doesn't have to be new, but I want to get a new one because I don't plan on programming it until I cam it.

So your basically saying keep an eye out for the AF? As in its death flashed or as in match that AF because it isn't?

Matched to the last two digits of what you have now. This way there won't be any problems with compatability...factory security etc...

Okay I understand, is there any way to figure out the flash specs?

Update: None of my local JY's have the part, I'm on Long Island NY, and our JYs suck.

what on earth is a death flash

nevermind, I looked it up.

It was an update done by Chrysler that would retard the timing to avoid a pinging in the plenum.

Ordered a new ECM due to not having any other option, I'll have the truck Dyno'd sometime soon and tune it, hopefully there's no asinine flash in there :/

On the bright side I'm on my way to a check engine being off and some real mods!
