Title: ECU Accees Denied ME7.5 Post by: Skyler471957 on May 13, 2021, 07:39:52 PM Hi all, I'm realitively new to the tuning community. and I've been trying to get my ecu reflashed, and my tuner wants me to log with nefmoto. and I've tried just about everything, including installing, and uninstalling various ftdi drivers, and different computers. here is my log

Does it have a riser? Is immo working (will the car start and run properly right now with that ecu)?
Title: Re: ECU Accees Denied ME7.5 Post by: Skyler471957 on May 13, 2021, 08:01:03 PM Thank you for the speedy reply!! :) it has immo delete, evap delete, and supposedly stage 2 for a k04-015 and 550cc Injectors. Yes it will run. and I have no idea what you mean by does it havea riser. I've also tried to datalog my original ecu with the same errors..
Title: Re: ECU Accees Denied ME7.5 Post by: nyet on May 13, 2021, 08:56:45 PM If it isn't stock, the tune may be inhibiting write, in which case you need to use bootmode to overwrite it.
If it has a riser (you have to open the ecu to find out) you'll need to replace the riser with a stock flash. If you don't have the equipment or skills to do so, you'll need an entirely new ECU.

I also have a stock ecu, and I've tried the same thing. and I'm just trying to datalog at this point.

And the stock ecu should have worked with NEF. Title: Re: ECU Accees Denied ME7.5 Post by: tadope on May 28, 2021, 08:42:06 AM Whats with the sleep mode warnings? Anyone notice that?
