For the average home user there are really only 2 ways to make configuration changes to your CEM
- Vdash
- P3Tool
Now lets talk about the Pros and Cons
Vdash
Vdash is a really amazing program with breadth and scope unlike anything else, it can clone modules, and allow you to use donor modules from Ebay and stuff you wouldn’t believe. But for this, I am going to keep to the very specific topic of P3 configuration changes. Vdash has checks and balances to help ensure that nothing goes wrong and recovery procedures in case it does as well as technical support.
Vdash is strongly recommended for the home enthusiast. Its also fully automated. In as much as you can create an account in minutes, add credit to your account to pay for CEM changes and be done all without any human interaction in a very swift manner.
OK, So, you have your CEM pin code and you have submitted to Vdash or decoded it directly with Vdash. What next ? And what’s the Cost?
Every configuration change in Vdash has a price, and there is a price list HERE
Typical costs for say, adding the steering wheel speed limiter will be 47Euros (Which is “Unlisted CEM change”, because there are 100’s of possible config changes, they cant all be on the price list).
More Advanced jobs might be 120Euros .
“Out of the box” the free account with Vdash has a limited range of CEM changes available to you. Very specific things might require q request to Vdash to open the menus for you. For isntace if you are retrofitting a higher performance audio system and amplifier, you will need to ask Vdash to open those menus for you
P3Tool
P3Tool is a very powerful but homebrew program. Getting an account to download requires sending an email to the maker, then when you have an account to make changes with P3tool you need to send 50Euros to the man, who then adds it to your account to allow work on 1 Vin. So 50 Euros per Vin and all requires “Human interaction” . This caan really hamper your workflow if your in an oposite time zone.
However, that 50euros unlocks access to everything the program can offer. 100’s of cem config possibilities enable or disable anything you want for the single sum of 50 Euros.
Much like Vdash it can sync a Donor BCM, EPB or FSM module, disable ITP security etc etc…all for 50 Euros.
But…..you are on your own, there is minimal protection and really no support. Vdash is strongly recommended for inexperienced users.
