If you got it setup so each table use one of the small switches on the side of the unit its easy to turn it off that way.
If you still got a problem then look at the harness for bad connections.
Sorry for a really late reply as I have just been driving around with the GEMU unhooked. I checked all the connections and it all looks to be hooked up correctly. The only thing that could give me any idea (but I don't know where to look really) is that even before cranking up the engine if the GEMU is hooked up the code P1259 shows up, something with VTEC. Even without clearing the code, if I connect back the OEM ECU, the CEL goes away. Whatever is making that code show is the reason why my car won't start.

I had some time to check everything I could think off. I cannot connect to the GEMU with my laptop, and activity light flashes GREEN ORANGE RED GREEN ORANGE RED. I have not been able to find what that could mean. I really miss the lower VTEC engagement and better AFRs since I'm running FBO.

Any help will be welcome as I am at a loss here. I tried connecting the GEMU to two laptops, one I always used and a different one, the laptops recognize some USB connection but I never go ONLINE and the Interaction light doesn't light up. Please mind, the VTEC Engine Check light is still on when GEMU is connected.

Are you using a laptop with XP? I think newer Windows version have problems.
Could be that the EMU unit is faulty, this is from the manual.

ACTIVE L.E.D
• Steady GREEN - - - - - - When the unit recognize Ignition ON
• Flashing GREEN - - - - - When Fouled Plug feature is activated (When engine is started with wide open throttle)
• Quick Flashing RED - - - - When Self Diagnostic has detected an error
• Flashing RED - - - - - - - When Warning is activated
• Flashing Orange - - - - - During Main Unit Data Logging

Yes the laptop I always used is a Windows XP. The other one is Windows 10, I think I got Emanage to work on Win 10 once a while ago.

That's good information you have there, but none of them show the flashing pattern that I have . The pattern is there regardless if the computer is connected or not.
It would really suck if this thing broke, because I was planning to sell it and get AEM last year, just didn't find a good deal.
