I love assumption being a city boy I've nothing to do with farming :) but my wife's family has so you think by my profile and a few thousand posts you assume naughty man.


ha ha ha i dont assume anything ?????????? but i wonder was there any point to your few thousand posts :D:D:D:D:D:behindsofa:

The petrol modes are more prone to loss of sync because the code rolls like the FOB, On the diesel the BECM to EDC code is fixed, at least that's what I've been told by a usually reliable source.

The BECM to EDC code is fixed on all versions.It is only the Fob to Becm code that rolls.

BECM to EDC is fixed but GEMS/Thor is not according to my source, happy to be proved wrong as I have never had cause to personally look at anything other than the EDC.
 
IM WRONG AND I WILL NEVER LEARN ANYTHING.

But I also Detest smarmy know all's happy now :)

Carry on

So you don't like people that know more than you. That will leave you with a very big problem on here unless you keep stum listen and learn. Did this problem start with a teacher at school knowing more than you did? :D:D:D

No wammers I'm very happy to learn its a persons approach being all high and mighty is no way to teach :):):)

Not according to my experience and what I have read.You can read the code in the BECM and EDC and it is always the same.The GEMs ECU is slightly different in that it can be put into a security relearn mode to accept a different BECM code,but that requires use of specialist equipment.
If you have documentation stating differently,would like to read it.Always happy to learn.

That's the point, the GEMS ECU has to re-learn the current BECM code which I understand changes on every start, a re-learn can be done with Faultmate which I have. I don't touch V8's, don't like the engine so no hands on knowledge.
I don't have documentation as it's not the sort of thing that should be in the public domain. It's just verbal info I was given in response to a question from a knowledgeable source. I could of course have been misinformed.

Did you ask your sorce Dave Ashcroft if he uses other garages too ;);)

The BECM code is always the same and is transmitted to the GEMs ecu provided the BECM has already received a valid fob code or EKA code has been entered.The Gems ECU compares this code to the fixed stored code it has and if they agree sends a signal which illuminates the Engine check light and permits engine start.This code can be changed if a BECM is used which has a different code by invoking the relearn via the Faultmate/Nanocom etc.Ie the BECM code does not change at each start,nor does the security relearn happen automatically at each start.

As a matter of interest the Diesel ECU can be set ,when new, to a Non robust mode ,which means it does not have to receive a code from the BECM to operate.However if it has been set to Robust mode,meaning it does need to receive a correct BECM code,then it cannot be reset to Non robust mode.

If you say so, I can't argue but it differs slightly from what I was told. Not bothered, as I said I don't touch V8's except if called to help a stranded tourist in France.

I know about Robust/ Non Robust.

Read the nano/ fault mate ecu info its in there :)

I prefer to call it a debate.Always interested to learn something new,especially if corrects my existing knowledge.
 
Just to clarify. Diesel Engines. The security code is implanted in the ECM, it cannot be removed or changed. The same code is stored in the BECM. When the ignition is turned on the BECM sends it's code to the ECM. If they match the the ECM becomes active. Out of sync is when the BECM code becomes scrambled and does not match the ECM security code. The engine will turn over but will not start. I believe the GEMS is similar. On the THOR the engine will not turn over in an out of sync state.

Happy with that, my info came from a software guy involved in diagnostics, it's quite possible I misunderstood what was said about the GEMS/THOR ECU's as I was specifically interested in the diesel EDC:)
