vtec will still engage even if you through a cel, depending on what cell you through your ecu can be put into a limp mode, this will no occure everytime it depends on the code, when this happens you will only get 80% of the timming and fuel
All stock honda ecus have 2 map programs, one for regualar no problem driving and one for limp mode
