I ordered a CarSoft adapter and software from Hong Kong about a month ago, still hasn't arrived.

If I use the above adapter what software are you using?

Next to faultcode itself comes flags what tells what is wrong with input/output: signal high/low, short to b+, short to ground, no signal and whatever, maybe flag, if fault is triggered by more than one times/limits? 01110010 signal low, 01110001 signal high, 01101000 no signal, tested: 11110010 si...

Pretty cool. You guys are going where no obdI motronic tuner has gone before. :-p

Mykk

Very cool. Just read the .txt.

Am I misunderstanding this or is the info you're reading off the external ram the same info that you would get from Rx & Tx serial communication used by CarSoft diag software?

Mykk

Very curious for your findings and developments.

Yes, right now a 3bar for the piggyback. But if I can motronic to run on map alone I'd use a 2bar map since it's only 8psi of boost.

Just did a few experiments regarding the companion tables in my 404DME. I must have done something screwy when I received error message earlier. In my test: Copy the data from tables in the 1st section and paste into 2nd section: Vehicle would fire up and run but was super pig rich and wouldn't resp...

Mykk

Stay safe & dry. I'm going to experiment some more on my end this evening.

Looking at the 413 Red, there are two differences in stomp codes between the two tables and two differences in DTC enable. In tuner pro if you make two 56x2 tables viewing hex, one starting at address 4484 and the other starting at address D19A. Open both tables side by side you can see all the flas...

Mykk

I haven't looked at your 413 yet, but in the 404 the redundant DTC enable table in the controller code has every code enable set to "0" , only a couple of codes are different numbers then the DTC enable table in the maps section. The blink code table in controller side has only a couple of...

Mykk

Nice find, really helpful. I think these tables are simply just for the human interaction of CEL and code flashing. By setting any one code to "0" doesn't tell DME to ignore the problem, it just tells DME to not let us know about it.

Mykk

I'm not familiar how to navigate excel to add my own info, notes & colors. I totally see now the first two cells being it's own reference address. The MAF has it too...that's really crazy to me. Obviously a DPTR is already drawing information from that address, why load the hex address of the lo...

Mykk

HairyScreech, I don't know how in-depth you want to get with the 404 in your spreadsheet. But you are welcome to my xdf if you truly want to label the majority of the tables & functions

Mykk

I have a theory about those DTC on/off and flash tables, but no way to test it. The DTC's on/off table is a 57x2 table that we recognize in hex format as "0 hex =no CEL" "16 hex = CEL on". The DTC's flash table is a 56x2 table with the flash code in little endian hex format all s...

Mykk

Did you found RPM axis for those IDLE/PT PT/WOT tables? I noticed interesting thing in MAF signal fail safe mode: Idle actuator position change slightly changes LOAD signal. Where is "table" for that correction? I think there must be something RPM vs. idle duty cycle dependent map or some...

Mykk

One more request? Any way to pull apart the transfer functions and thresholds between D4C8-D598?

I recognize the 32x1 TPS transfer function @ D4F8
Also the Idle - PT and PT-WOT thresholds @ D53C & D540

The rest I don't have the ability to identify.

Mykk

That's amazing. Thank you

Mykk

In Red 413 soft 623 do you know what is the bit of data located between D19A-D20C?

Seeing as how it's sandwiched between DTC code, I'm assuming it's more DTC code?

Mykk

I can verify on both 404 DME and 413 Red DME, at address FE14 there are five hex code addresses (that I can recognize). 404: C0 00 - Start of table code C1 1A - DTC's on/off C2 A6 - MAF table w/ header D0 3E - Table of Tables D1 4A - End of table code 413 Red: D002 - Start of table code D106 - DTC's...

While I was watching the cell hit tracing via Ostrich, the tables with CE axis seemed to only follow RPM. Looking at the header info of CE it follows the same calc as RPM (x*40, subtract from next value ). Once the axis was labeled based on header info once again the cell hit tracing followed suit a...

Mykk

Impressive amount of work has gone into your spreadsheet. While tearing apart my M3.3 404 code I've come up with axis descriptors: D0 & CE = Engine RPM D7 = Water Temperature D3 & D4 = Intake Air Temp D5 = Load D6 & CC = Throttle Position Sensor D7 = Water Temperature D8 = Voltage 1C = V...

Mykk

Have you guys discovered any more goodies in the code? I'm anxious in anticipation of the advancements you guys have been making

I wish I could help but you guys are figuring out bytes if data on an entirely different level then I'm capable of.

Mykk

Thank you olafu, I've adapted the DTC's that I could. Truly appreciate your leg work

I too support finding all of / or the majority of DTC's in the code

Mykk

Thank you for figuring thsee things out. I've adapted most over to use in my 404xdf. Thanks!

Mykk

Open to ideas. This application has supercharger, would like to get away from MAF

Mykk

I'm trying to convert my M3.3 404DME (64k) V8 from MAF to Speed Density. Theoretically by using the mod talked about in this thread I can use the MAF in hooked up to a MAP sensor and allow it to reference a RPM vs MAP table, populated with similar fueling values used in the MAF table. The table to r...

Mykk

Is D3 descriptor IAT? What formula are you applying to get temperature to the header info?

Mykk

Today I was able to get my hands on the rare and elusive E34 540i/6 404DME original chip. You have no idea how hard it was to find one of these as a 404DME. Every take out DME I could find was auto trans, I'm happy to present the manual tune. There are more changes between the two in the coding then...

Mykk

Here's a quick 484 .xdf with the maps identified by pulling apart the hex code. The axis are unlabelled since that is the most time consuming part of the process. Checksum correction is in this xdf. If someone can find it useful and build upon it, that would be cool. If and when I find out how to di...

Here's a 12/1995 E38 740il, 484DME chip numbers, 1 744 605, 1 265 358 772. This is an EWS file. It will not work with the existing XDF, I believe this this to be a DME for the non-vanos M62B44. I'll spend some time with it in order to make an XDF. https://drive.google.com/file/d/0B3ENo4LvAtklcnRYbmh...

Mykk

Here is another E34 540i Auto 404DME that came in. Production 6/1994. Chip # 1 744 050, 1 267 358 720.

It is slightly different then the previously posted E34 540i and E32 740i tunes.

Also, here is the XDF I've made for the 404. It's far from complete, but I made it by pulling apart the hexcode and using the readily known axis identifiers. It also has automatic checksum correction, just remember to save your bin before loading it to your emulator or burning a chip for the checksu...

Hey guys, I just recently picked up a Burn 2 and was able to read a couple OE chips. One from an E34 540i Auto, the other an E32 740i Auto. Both with chip numbers 1 267 358 720, 1 744 050. They are subtly different from each other and drastically different then the 357689 404 tune on the TunerPro si...

Just my .02Â¢... I'm currently learning about Checksums, and since it's on the fore front of my mind I'm going to suggest checking it out to rule it out. Because when you're a hammer every problem looks like a nail. Goto XDF Menu > View/Edit XDF Header info> Checksums tab....Is it blank? If so you'r...

Mykk

If my Motronic M3.3 cranks, fires up and runs without a checksum adjustment do I need to worry about it? Or is it still a good idea to have the checksum match every change made in the tune?

Mykk

The available M60 xdf is pretty rough. It's a starting point for sure and should be taken with a the best educated guess judgment. I've been tuning my 540i on a 404dme for a while and I noticed with my MAF table while cell hit tracing that there doesn't seem to be any load dependency thus no need fo...

Mykk

Hey guys, I've been slowly piecing together an XDF for my E34 M60B40 404dme. The XDF was created by ecuconnections XDFcreator using the 413 values, as the 404 values are unknown and the 413 settings yielded results. So, obviously it's not perfect. I've spent months (off & on) deciphering the tab...

Mykk

I just wanted to revive this one from the dead. I've been blindly experimenting with my tuner pro XDF's, as I'm still learning. I've spent a couple days focusing on the MAF table. I've used the available xdf for the 404 (I'm assuming it's RevLimit's), while watching the cell hit tracing with my vehi...

I really don't think so. I made the jump from Miller WAR chip on my M60B40 to an Ostrich 2.0 chip emulator running a mod tune.

Hey guys, I'm in desperate need of a definition/xdf for a mod tune that was created in WinOLS to use in TunerPro. I have downloaded WinOLS free and started playing around.

I'm afraid I don't know. Still falling down the rabbit hole, err...learning as much as I can about tuning bins and the code/software involved

x.75 -45 can be a realistic timing curve for an M60B40:

I do still need to make my own xdf/xds for a different bin, learning how to via as many resources as possible right now.

I'm beginning to think it's an xdf issue. I'm researching now how to make my own xdf's

Also, I suppose I'd better make sure I've got my MAF theory worked out too... the Bosch 404 DME Motronic 3.3 with the hot-film MAF is 0v-5v variable and not frequency based...right?

Hey folks, I'm currently putting together a little project on my E34 540i 6spd. I have been running a flashable Miller W.A.R. chip in a 404 DME for quite a while now.
