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.
