Now the only thing that is bothering me is what happened at 49%... :/

Maybee new sw mpps work like nefmoto flasher...and rewrites only the modified tables..the rest doesnt matter to...

But not sure...

No one experienced that when flashing EDC16U31 engine?
I guess I'm not the first one here to flash this ECU with MPPS

**ipejasinovic** · 10th March, 2011, 09:54 PM

Of course. Flashed more than 300 times...

@ipejasinovic: you never saw this issue like I had today when flashing stops at 49%?

I would just like to know if this behavior is normal for clones and 3.0.2.37...
I have a "euro" style clone in plastic OBD casing.

MPPS on ME7 only rewrites the sections/blocks which have a different checksum. Just like nefmoto.

Nefmoto->MPPS though.

now i manage to upgrade my clone in aluminium box to v5 but instaed of having 512kb file as with v4, in v5 i get 162kb file and a message to send it to amt-cartech.

also tryed to upgrade an second clone to v4 all ok but when upgradind to v5 it bricked with exacly same serial number as the first one.

Send it and see what they say...

Also post the file here (or PM it to me) so I can see what it has inside.

does mpps work great at me7?
A.g. 18T Vag cars
Or maybe problems with 512kb and 1mb

I had same but not sure which ecu...was ssome seat with edc16...

Also stopped at 50-55% told me checksum error...

Turned off ignition,tryed start...and run fine...

Read one more time file,and was the mod one..all ok.

This was with ori mpps aprox a yea ago..so with soft before 3.0.2.x i think.

I had same problem in golf plus 1.9tdi edc16 90hp. Same s..t always stops at 49% with checksum error even if I correct checksum before. This is with GENUINE MPPS not clone. Guess what ... 19$ galletto clone did the job flawlessly.

**TribesMac** · 11th March, 2011, 08:40 AM

@bazare: but did the car start after that error with MPPS? Or you had to recover the ECU?

Anyway good to know

Maybe I will use Galletto clone next time, just to be safe

(I've never imagined I will use words "safe" and "Galletto" in the same sentence)... :roll:

**bazare** · 11th March, 2011, 10:27 AM

No, car doesn't start after that ... but I can write back the original always with no problem. When original reaches 50% says "flash complete" and process is closed, car starts. I think it's not a problem with the flashing but with the check-sum calculation. It would be nice if you can turn OFF check-sum calculation while writing.

bazare: It looks like MPPS has problems with EDC16C/U3x...

It works fine on "older EDC16" like VAG EDC16U1, or Fiat EDC16C8... I have written many of that ECUs, and never an issue.

Yesterday I had a funny moment with EDC16U31 when it stopped at 49% but the car started fine and ECU was written OK.
Today I tried to write EDC16C39 in Alfa GT Q2, and it came to 99% and the MPPS told me that there was an error and it would like to send error report back to AMT. The car didnt start after that (immobilizer, ASR, VDC, and all kinds of problems flashing on the board computer), but I was able to write back the original file without any problems and car was OK after that.

The checksum was calculated before writing the file, so I guess this must be a software issue.

I wonder if that issue is fixed in later versions of software.

**ipejasinovic** · 11th March, 2011, 02:19 PM

I can assure you that original MPPS and some good clones, can flash EDC16U31 without any problem. But, yes, sometimes can go wrong and stop at some percentage. A lot issues can be connected with such behavior. Cold solder joint in device, damaged OS, damaged installation of MPPS, damaged ECU etc...

Also, some Gremlins can be reason why something doesn't work.

P.S. "Damaged OS"! For some unknown reason, MPPS is very sensitive on minor malfunctions in operating system. On one system, drivers are installed correctly, MPPS is running, but some strange errors occurs every time. Install it on one other PC, everything goes with flying colors.

But also CMD 2MB files work with mpps. So you can flash cmd files with mpps.
But i am not sure if you can to mpps files write with cmd (because at the beginnig of the File only FF FF ... ) ???

this is good to know, that can write cmd files with mpps
