Disconnecting battery and the effects

[supra-alex]

if was to reset the ecu by disconencting the battery for at least 1 hour would my alarm settings be lost when i come to put it back in ? Would there be anythging else i have to do regarding the ecu ? changed fuel recently you see...

 

i have a clifford concept 900 ?

 

thanks

if your after resetting the ecu you dont need to disconnect the batt??

why not just pull the EFI fuses? - put the clifford in "valet" mode then disconnect the battery, when you reconnect - it will be fine.

oh ok, how do i find the valet mode on the fob ?

 

would doing that though reset the ecu anyway ?

Removing the EFI fuses (for 10 seconds or so) causes the ECU to relearn and in doing so it will 'see' the new fuel. You don't actually have to do this as over a period of about 10-20 miles it will 'see' the new fuel anyway. Removing and replacing the fuses only speeds up this process.
