UCDS Forum

Hello everyone.

Does anyone have a tutorial on HOW TO REPROGRAM THE PCM using UCDSys? I am affraid it will brick my module. I intend to modify the engine output.

Dont worry! PCM is not BCM
Just make backup by saving .uuw file and GO GO GO!

Just "do" it...

Just backup car uuw file
you can do anything

I did not understand what you would like to change to get more power.

I assure you that with my Mondeo 180PS the only way to give more power and torque is to change the PCM ECU.
Now I have 218PS and 478Nm and it's great.

A beast has become.

No error in DTC.
No Recovery.

Mine was originally the 150 bhp/370Nm.
I changed in UCDS /PCM the engine power to 180 bhp.
And I did a remap on this hp.
Now I have 225 hp / 485 nm.
Just fine, no problem at all.

I state that the PCM of the Ford Mondeo has on board the curves of the 150CV, 180CV, 210CV, but even if in UCDS I'm going to change these values for example from 150CV to 180CV in fact I do not get an increase in power.

You modified it, but you could have avoided it, because then you realized that the only solution was a modified ECU.

And to reprogramm the PCM I should do the following steps?
In Mondeo icon -> PCM Procedures -> PCM Programming -> Select type -> Start programming

And how do I save a backup?

Just answering...

I tried to.

The UCDS did not save ECU Serial, and other data.

Result: PCM does not work. Can not recover previous programming. It says it can not find PCM/ABS data or error in retrieving them.
I´ll have to get my car to the dealer, towed.

Told you there should have a back up.
