Peugeot 106 S16 (1,6 16V) Rotrex c30 84 conversion.

VemsTune 1.3.1 / 1.4.9

Vems V3.3 PnP for Peugeot 106 GTI (dp-engineering)

Vems Serial Number 1869

Vems Firmware 1.1.97 / updated last year from 1.1.64

VemsTune runs in VMware Fusion on MacbookPro (had no problems at all until now / tried different laptop and in different car too)


At the moment I have a serious problem with my Vems. The car ran fine but recently after a short trip I could not start it anymore.

After connecting the Vems to the laptop i got the following error message:

"Boot node detected." (Choose Stay for firmware upload ....) *1)

In 'stay'-Mode I uploaded the firmware 1.1.97 (and lateron other version) again. The upload process seems to be normal. (He's copying 4xx Pages) but the following validation fails. *2)

The Vems do not show the real SerialNumber which is n001869 *3)

I found some other hints from Jorgen in the Vems Support Forum which I've tried using megatune / megaloader

Again I got validation problems

error at page: 0

too many errors, bailing out *4)

Directly after the failed validation the connection to the Vems is normal. Its possible to upload configs and even the engine starts (in some kind of security mode). But after switching the power off and on the boot mode error appears again.

These guys seems have had the same problem

Both changed the atmega128 to solve the problem.

Is it possible to change the atmega128 in Vems PnP from dp? Do I need to upload a special bootloader by using spi afterward and is there other stuff I need to do after the change? (never used spi before)

Any other Idea?

Thanks in advance!
