The code is stored in parallel flash, but is updated via a serial link. I can update 32 K bytes in an E46 M3 in about 2 minutes, but some other DME's such as the one in an E36 M3 are much slower. When the complete DME is re-programmed, it typically takes about 15 to 30 minutes in most BMW's. I can program 512 K bytes of a SMART car ECU in only 2 or 3 minutes, it has a really fast interface and some fast FLASH.

But at the end of the day, this process is effectively serial ("sequential") in nature. This would be WAY slower if you were picking random bits of memory to update, particularly if the data chunks do not fall on flash sector size boundaries. > The code is stored in parallel flash, but is updated via a serial > link.

I can fill a 512MB iPod Shuffle in under 5 minutes, but it's got a similar architecture (ie fast interface, fast flash). - Mark ----- [EMAIL PROTECTED] Check out my JustRacing Home Page at: http://www.justracing.com/homepage/mdadgar ------------------------------ Date: Wed, 15 Jun 2005 10:40:26 -0700 From: [EMAIL PROTECTED] To: bmwuucdigest@uucdigest.com Subject: Re: Reprogramming DME Message-ID: <[EMAIL PROTECTED]> Dennis, As long ago as 2001, my Sierra with OnStar had the remote diagnostic download feature. -Kevin ------------------------------ Date: Wed, 15 Jun 2005 11:33:44 -0400 From: "Mark D'Sylva" <[EMAIL PROTECTED]> To: <bmwuucdigest@uucdigest.com> Subject: Re: Reprogramming ( E39 M5) DME Message-ID: <[EMAIL PROTECTED]> > > Date: Tue, 14 Jun 2005 11:37:10 -0500 > From: Jamie Howton <[EMAIL PROTECTED]> > To: "Steve.Goldstein" <[EMAIL PROTECTED]> > Cc: bmwuucdigest@uucdigest.com > Subject: Re: Reprogramming DME > Message-ID: <[EMAIL PROTECTED]> > > On 6/14/05, Steve.Goldstein <[EMAIL PROTECTED]> wrote: > > No kidding!

I've encountered at least four 2000 M5's which all had the original code in them. There was a problem in that code which made them very hard to update at the dealer. Some DME's actually went dead when the update was attempted and had to be replaced. The GT-1 can now update these DME's and you should try to get your updated. You may find that the interface speed improves. I could read from these DME's but not update the fuel and timing maps until I installed the latest BMW system code.

They replaced the MAFS under CPO warranty and the car wouldn't run afterwards, they had to re-program the DME to get it to work properly. I haven't tried to connect the Autoauthority reader since then, I'll give it a try and see if it will connect at a faster speed now.

Very common failure on these cars. Sometimes you can 'unstick' it by whacking it a couple times. Just a short term fix of course; you'll still need to replace it. I had a similar fuse problem once and the issue was a block aux fax. Picked up a piece of foam that blocked the blades. Every time the fan tried to kick on, the fuse would pop.

At around ET38 with some tires that have square shoulders, and where the car is lowered quite a bit, there have been known to be problems, but all 3 factors have to be in play. -Kaz 01 325iT 88 M6 >I have a buddy who is interested in getting a set of 18" wheels 18x8 >most likely a 40mm offset and wants to run 235/40/18.
