Yes I know what you mean...BUT my issue was a different one.
When I first had a misfire in cyl 1 when running the newly updated v401, I put a new coil in and went back to v301 (cause I never had a problem with it for months). I gave it a try again this WE and almost immediately got a misfire in cyl 6. I will exchange the coil as well tmrw BUT I wanted to know why it could be that I start getting a misfire only after switching to the v401 maps?
Thanks...
