I am about to start flashing (after months of study) and it dawned on me that there are no official instructions included with ECUFlash. I found limited stuff on YouTube, but I would feel more comfortable with real step-by-step instructions....including common troubleshooting steps (like 'Don't turn off the key if the flash hangs'). I tried searching these forums but the keywords are too common.
Are there any formal instructions? Informal ones?
