today i had toupdate an ecm on a c2 i have done this many time before without issue but today after the update was done and i clicked the finish button it should me a list and the list was called parameters not restored and in that list was engine protection/engine coolant level/ and torque derate. so i went to parameters and went to the coolant level sensor folder and it says locked read only so i cant change it and now the engine light with the check in it is on usually thats on when coolant is low anyone have an idea how i can correct this parameter

before you made a copy of your features and parameter before you updated?
just compare the two , could be source address is wrong for that sensor

Reload the image you created before you attempted the update and start over.

yes and you'll see source address for a few parameters( like a C2 with BH!@# on LCD display , then goes away-after you release the park brake- well the source address for parking brake is wrong- change source address to ICU and that message goes away)
I just wanted you compare the source addresses for everything
or you can make a template of old ecm image and send it into the new ecm using INSITE
