Phedra 2.2jtd edc16cp39 not found with edc16cp39 protocol, read as 1.6hdi edc16c34

[teoturo]

Dear Sirs,
900kms far from me I cooperate with a south-italy garage, they use a simple MPPS v12 and had today a Lancia Phedra for remapping.

Car has edc16cp39 ecu (see photo)

MPPS has no edc16cp39 protocol for Lancia Phedra/Fiat Ulysse/Citroen and Peugeot identical models, so he tried to read with Fiat edc16cp39 protocol. "Ecu not found" was the result.

Mechanic tried to read ecu with edc16c34 Peugeot 1.6hdi protocol, and ecu was read with attached file.

Question is: will MPPS be able to write the ecu with the same protocol? I ask this because it's strange that 2.2jtd engine with edc16cp39 can be read with edc16c34 protocol for 1.6hdi engines, so I'm not sure if interface will be able to write and to calculate checksum.

In addition, is DPFoff ok in your opinion? I never worked on these 2.2 engines.

DPf looks ok, may work, but i would NOT use MPPS on that ecu....too few cehcksum blocks..it may brick ecu.

Have an idea of the reason why edc16cp39 protocol doesn't work and edc16c34 protocol (wrong) works?

What if MPPS writes a file with checksum already ok? In case, could you correct checksum?

[ominimicu]

checksum on mod files is not corrected, which makes me think its ecusafe solution for DPF off. strange you read via edc16c34..but MPPS is that wierd. problem is that he doesnt correct checksum as edc16c34...
i dunno i wouldnt write it unless you had a BDM just in case!

Don't use MPPS for this ecu! If you have not another OBD tool use BDM.
