Hi all.
Following on from the conversation with DaveW on Bolt's thread about my Thor emulators I have been looking into this infamous F-Out box for the GEMS engine ECU.
I must admit, I didn't find a lot of information aside from the technical bulletin out there, but I thought I'd have a bash at replicating one.
I am pleased to say that after a few false starts I have successfully been able to reproduce said item so now the GEMS ECU no longer requires an emulator if running standalone or with a problematic BECM.
Demonstration of the outcome on my youtube channel, which I have linked to below.

Hope this may be of help to some.
Cheers.

That should be of great importance to us with GEMS P38’s. Thanks Si.

That sounds great

Hi Simon, GR8!

Good work/deduction Simon, Cheers !

Dave,
it was you that fired up the creativity, so thank you.

I checked mine with Nano, and it was already set. Do you think this is as good as the Mobi-lize?

If you check it and Nano says Security Set, it means it has received a valid signal from the BeCM, it's only when it says Unset (or No, can't remember) that you have a problem. However, if you have a Nanocom you can go into Security Learn (Inputs-Others) and cycle the ignition on and back off again. Security will change to Set.

Thanks Richard. I’ve been meaning to order a Mobi-lize but I guess I don’t need to.

Harv,
I had no idea what the Mobi-lize was or existed until you mentioned it. Looking at the information I can glean off the web (I think that the product is discontinued) , it looks like the emulators I used to fit to the GEMS ecus.
On the nanocom, the Security Mobilize bit with a YES means the ECU has either received a correct security code from the BECM or the immobiliser has been switched off.
So basically it means the ECU is in a ready to start / run the engine condition.
If it is NO, the engine will not start.
So on your motor, I'd expect to see it in the YES condition as it's received the correct code from the BECM.

Thanks for that. I still wonder if the BeCM can send a signal to immobilize the ECU whenever it decides to, that can’t be overridden just by selecting YES on my Nanocom. I’m probably overthinking this though.

BeCM doesn't send a signal to immobilise, it just doesn't send the mobilise signal when you unlock the car if it thinks the car needs to be immobilised. Hence no check engine light as the ECU doesn't power up without getting the signal. Admittedly, on a European car, that is about the only function of the Check Engine light, to tell you the ECU is powered, it doesn't come on when the wind changes like on your NAS car.

Ok thanks Richard, that’s also good to know.
