These are the same issues that I have with my setup!
And I'm running the old 530iT automatic DME, with the WAR chip (I think mine was used to develop their M62 base tune).
[EDIT: wrong wires]
Would one of you noticing a hanging idle do this, for research purposes: disconnect your IACV after the engine has warmed up (it'll probably have trouble starting in cold weather), drive around and see if you notice any change in RPM dropping, and in initial throttle response.

I'll be doing some tests on the 404DME on how to fix this issue of running it like a manual. i have a dinan bin saved(my old 404 chip) on my pc that I'll try out in the 404, i don't remember my b40 swap ever hanging like this with the clutch depressed when moving.
Jon, have you called Dinan yet?

Naw, work was too busy today. I will try to do it tomorrow. I also don't know what wires Moroza is talking about. From the wiring diagrams I cant see anything different between the auto and manual asside from the trans computer just not being there.
I will keep looking.

Doh, brain fart. Those pins are on the ABS module.
K, with the 484, we figured out that the hanging is in the chip itself. So I'm sure the 404 is going to be the same.

Moroza, I think the ABS module also needs to be reprogrammed to not look for the trans computer anymore. Didn't you remove the traction control from your car? Thats all in the same module with the ABS.

This is interesting reading, as mine is like a bit of a lightswitch now at 3K rpm after installing the WAR Chip. Though I can pull out some advance/fuel to soften it I suppose.
Mine is 404 DME
It is also 5HP30 Auto.
If I can get rid of it, it's going to help with the 3.45LSD change. Otherwise I'm really not gaining much.

I removed ASC, but kept ABS. Replaced the ASC/ABS module with an ABS-only one from a 740. RealOEM says that there is no difference between ABS modules on auto cars vs. manual ones.
Still, I'm going to drive the car in a couple of days with the ABS computer completely disconnected (also to test a top speed issue).
If I find a 530iM in a junkyard, I'm going to pull its DME and see if that changes things.
I am pretty sure the 3k rpm thing has something to do with not pushing all that power instantaneously to the automatic trans. It may be more noticiable with a more radical (than stock) tune, but I don't know that I would try to get rid of it if the car is still an auto. It might be asking for a failure, though I don't know for sure.
Ah, thats right.
FWIW: Real OEM also says there is no difference between Manual and Auto cars with regards to Traction Control unit or DME either...In both cases its the programming that differs. I am sure ABS only wouldn't care about an auto trans either way though, so there shouldn't even be a programming difference there.

For those of you that are curious...
I was unable to actually program the dme OR the Trac Control via the diagnostic software ...guess I'll go look for an asc controller from a 540i/6.

You already tried reprogramming the ASC unit today? We can still plug mine in so that you can be 100% sure on it, even though the diagnostic is you telling so already.
Do not buy another DME, Jon and I tested his Dinan chip in my 484 540i/6 DME and also in my 484 530i/5 DME, made absolutely no difference from his 484 540iA DME. Put my 540i/6 chip in his DME and problem was fixed.

Cameroguy, I've got a trac control slash abs unit from my donor car if you want it.

Hey guys,
Our files for the 530 and 540 are based off of their Automatic counter parts. We have never seen a true manual transmission.
usually there is "fuel cut" related maps that differ slightly for auto and manual trans cars as well as some other small things that may be responsible for the hanging rpm after the conversion.
We are looking into this for you guys.
Ftw!!!!
-Alex
What's the word?
Could we send you a 530iM (easiest to find) chip, and have you copy its code, then change the fuel and ignition maps to what you put together for the M62 tune? Or would you need the car on your dyno again?
Let me know, and I'll find such a chip, and either send it to you, or hang on to it until I'm back in Canada (should be in a couple of months).
So, if we do a 6 speed swap, it might be wise to buy an after market 6 speed based performance chip?
That is correct, except for the problem with EWS. There were no 6-speeds in 94 (pre ews 2) so you can't get a code free chip. Most performance shops have you send them your existing chip to copy the ews info.
I do not know if they copy just your ews info, or if they take your chip and overlay some performance maps. If its the latter you will basically still have an auto chip. If its the former it would accomplish what you want.
That said, if you get a 6 speed chip that has ews info on it already, it can be aligned to your car it would seem

That should work, but it has to be from a 404DME, the 484DME has so many differences from a 404DME that it's hard to tell which code is responsible for this problem.
While we're talking about these chips, does anyone have a 1995 540iA stock chip that they can mail to me? I would like to compare it to a stock 540i/6 chip and try to find the EWS code location and also the auto/manual differences. I only need it for 30 seconds to read the chip, and then I'll mail it back.

This is very interesting. I have done the 6 speed swap in my 94, I do not have EWS, and no problems with any systems. I do however notice the hanging. I have not really noticed the 3k rpm switch but I have not looked for that really.
What is the best solution for a 94? Can a chip from a 95 6 speed be used without any issues ? Aftermarket 6 speed chip ?
OK, since I missed this when it was new, I'm glad it got bumped. After reading it, I got curious about the situation, and I looked up a WAR chip for my 540i6. According to their page, they don't have a chip for the 484 DME, which would be what a 95 540i6 would have. Then I got so concerned that I PM'd Brody, then got even more paranoid and went out to check my DME.
So the interesting bit is that I have a 9/94 build 540i6 - I knew that beforehand. But I wasn't sure if I'd have a 404 or the 484 DME, and when I checked it this is what I found:
I have a factory stock 404 DME 540i6. This makes me happy for a few reasons, but it seems to me that maybe my chip might be of some aid? If so, I'm willing to assist, but I'll warn now that the 540i6 is my DD.
Also, what's the deal with this orange sticker on the back? It's been torn, like someone was in the DME at some point, but I'm not gonna open it right now myself.
Also, for verification in case anyone thinks my car was a swap, here's the VIN plate - HE53.
So, is any of this interesting to anyone but me?

No, a 95 chip would not work because the programming is different due to the EWS software. But, see below
If you bought a war chip, then I bet Dima would be interested in borrowing your stock chip briefly. Also, brody and company might be interested in tuning off a 404 540i/6 base tune as I think they said their base tune is off auto cars. BTW, this is what 540man needs fo rhis 6 speed swap.

Well, I haven't bought anything yet. I've been planning to get a WAR chip for a while, and reading this earlier reminded me to look at it again. That's when I noticed that they don't have the 484 DME in their list on the page. But like I said, I'm willing to help if I can, but I need the car to drive daily. So here's a question (I think I know) - can I just drop in the DME from my 94 540 that's currently just sitting waiting for me to sell? I can't drive that one because it's not insured, but if the DME will run the 95 (and I can't see why it couldn't) then I'll be willing to let people read my 95's chip.
