I have added a hand controller & i was going to change the master fuel to allow for the larger injectors,  also to allow the car to be moved checked & finished off ready for a tune,
discovered that the ecu has been locked previously & shows CODE #=252Â Access Denied,Â
i would like to unlock or even re-set ecu, is there any way to do this via the hand controller,Â
I have had a search & tried #255, maybe i'm not doing the 'store' quite right? as once code number chosen with the adjust buttons i then use the up ^ select  to get Access Denied,
any help would be appreciated thank you
