Focus RS MK2 Cracked!
We have been working pretty hard on this ECU to allow OBD remaps, and so they can be remapped without ECU removal,
Its taken a long time to reverse engineer this firmware but we have written a map to one today via OBD
We belive we are the first in the world to have done this with the genuine RS firmware

Due to the internal firmware security, it has never been possible to write data to the ECU via the OBD without first removing the ECU,
We have been able to remap them via BDM for some time, but it can cause warranty issues. and it means removing shear bolts and open the ECU itself.
We now have the ability to write data via OBD so the ECU does not have to be touched,

Superchips refer to the bit where they take the ecu apart and rip the RS firmwear they cant get round off and replace it with ST firmwear they can get round as "bluefin enabling" the ecu

Does it really make that muh diffrence? Ford can check if the ecu has been modded without even lifiting the bonnet to check the bolt.. Is there going to be a premium to your service compared to others?

As far as I am aware Revo can only remap via BDM (ie rip the ecu apart and attach directly to the chip) likewise for superchips.

Top work! Do you have any estimates for power and torque figures yet and is it just the one map or have you written different variations?

The maps we have done on them so far have given really good results, but this will open a few doors as it now becomes much easier to do. And it will allow some of our other installers to do them,if they buy the equipment, not just those who have the BDM

Thats the same with any Handset James, what Im getting at is if theres an engine failure or turbo failure etc ford will want to check the ECU.. Although you havent removed the ECU from the car they can still see if anything has been uploaded etc granted the dealerships cant be ford Hq can and if anything serious happens there going to be the ones to check things over

You are very much missing the point james is making there mate.
With the evolutions kit, you read the file off via odb, you write it back on via obd, the car is exactly as it was before.
With other bits of kit, you open the ecu up, you alter the firmwear, then you close it up.
Then you can read and write the original file back and forth via ODB and you are still on altered firmwear. So the manufacturer would still be able to tell its been fucked about with.
Can they tell if you have put it all back EXACTLY as it was before though?
As far as I am aware, they cant.

O ok i get it now.. But iv been told that ford hq can determine if the ecu has been "altered" in anyway.. Just like the ST ecu, that didnt need opening etc but they could still tell if there had been files put on even if you put it back to stock tune etc

It may be there is a timestamp on the file that the mappers cant access or something like that, or it might be that their are rumours to that effect to try and put people off remaps but in fact its all just nonsense and no such check can be done, only ford HQ will know that and I doubt we'll get a definitive answer from them, and even if we did, we wouldnt know if it was honest

Indeed, unless they actually get hold of the car from MSD and look into it, they wont know if they can find it or not, they might *think* they can, or they might have no idea, or they might know that they cant, but we wont get told either way.

ME9 has a flash counter, but there are ways round that as with anything. Great things with BDM is that you can essentually clone an ECU as you get a full read of all data. Not much good for warranty purposes nowadays due to tamper proof shear bolts etc on the ECU.

The ECU will have a peak boost and peak RPM counter in it so that will be the easiest way to tell if it's been played around with (assuming boost and rpm is increased).
Regardless, congrats to the MSD boy's for allowing RS's to be remapped a shit load easier
