Mine does that...
What you need to do is turn your key to "Acc" and wait for the light to blink. Don't start your car right away...put the key to Acc...wait 5 secs so you can see the blink....then start your car. It won't flash after you change maps, just when you initially turn on the car. Plus, as I'm sure (I hope) you know, map change is not "on the fly" for the Utec. You can change maps, but it won't take effect until the RPMs drop below 1500 or so (where UTEC takes over for stock ECU).
I'm on map 3 so my CEL blinks 3 times and then holds on the 4th.....
