@ rob.mwpropane :

Great proposal ! Only the programmer/chipadapter is essential to read it out. And not alot offer their services online in your neighbourhood as of this sadly

I was thinking...  Do you have a M7.5 or M7.1  flashrom-socketed ecu laying around ? If yes, this might be the way to abuse it :

With the nefmoto software or Galletto or MPPS or other bootmode-capable usb-reader, under bootmode, read-out the content via the M7.x ecu of the other
flashrom ?  I know this is a very crude method, but this may very well work ! ?

Don't do this right away, as i need to see pin-compatibility between the 200 400 and 800 chip.  It was merely thinking up out loud... But perhaps a unorthodox
solution to get flashroms readed-out

If another helpfull guy in rob's neighbourhood can assist with a real programmer, we'd also would be happy. Do chime-in guys, with thoughts and ideas !

Hi,

Thinking 'out of the box' sometimes helps alot

Emm, i was thinking. Galletto does a check perhaps, which minimon doesn't  (also capable of doing bootmode-reads)

I've added a screenshot of my software with the correct setting and a red box what should be instantly pressed.

But first, you should take your time, and finish the benchflash-harness. I already have that work done

The idea about this way, is purely theoretical, but perhaps we can make it work in real-life to overcome the readout-
issue when we don't have a programmer laying around. It would be smashing, if it worked

And ofcourse, all stuff would be purely for education purposes. Thats what this site is also about, if i'm correct.

"I downloaded galletto program from this site, should it just pick up the correct driver when I plug in the cable/ECU automatically?" ->
direct windows to the folder where the galletto software is in, and there should be a Driverfolder inside that with the
right "ftd2xx.inf" file in it. thats the one to select, and then your install will be correct as of the driver.

The main software can be started right-away. (in my case NEW_SERIAL.exe)

I run winXP-SP3 btw. All other O.S'ses should make sure, they run the app as ADMIN !!!

Now hopefully my hack can be made working   I can also try this over here, but need to firstly solder-in a meritek chipsocket, and
desolder the 2 flashroms...

First some extra homework, if i didn't have overlooked something.... Theoretically, putting the processor into bootmode would give the
program access to read and write the flashrom without any moaning.

Getting back on this subject asap.

Greetings,

Pvl

Wrong answer...
6D9C (8-bit) = 250rpm - RMP hysteresis when tranny guard active
6D9D (8-bit) = 1 sec - time for automatic tranny converter guard

Another addresses is part of exe-code...

Is 743A for the 3.8.2 (clemens file) = speed limit on velocity error detection signal  = 6800 = NMAX = Rev limiter? - It's the only address labeled NMAX that has an RPM value.

If it is, I think I found the rev-limiter for the 5.9.2

And how exactly does ME3.8/5.9 set rev-limit? - I've been getting mixed info, from reading and directly from guys that seem to be in the know (is it calculated or is there a set RPM like in every other type of ECU)

EDIT: 743A is the same address that PVL posted on page 2.

This might happen to be an old thread, but where do I find the ME3.1 manual? You can't really search for it, as it comes up with anyhing that contains "ME3".

Thanks

Been reading this thread, because I am interested in tuning the 557P for my 99 Passat with the AEB. I actually have a spare ECU for it (bought from a member on PassatWorld for $20).

I have a bench harness made, and have successfully read it using VCDS Lite. I also have a MPPS v13 cable, but from there.. I am not sure where I am going.

I know the ECU is a 8D0907557P, which should be a ME5.9.2. I have seen some differences in versions... D02, D03, D04, etc etc... Mine is a D04 (according to the sticker on the front).

I downloaded PVL's D04 file, and open in in WinOLS, and it asks me info about the vehicle. I put it in, but I don't get the list of "toggles" on the left.

I think I need a crash course in WinOLS....

My goal is to be able to do some minor things like rear O2 delete, mild tuning for exhaust mods, etc. Nothing major. I have this spare ECU to practice with, so if I do kill it, I still have the original ECU to put back in the car to run it.
