Hi all..this is a how to question...i have to take out my ecu to peek inside to indentify if it's been chipped or not..what are the do's and don'ts with regards to removing it for inspection? thanks in advance

 

Pull the passenger side front footwell carpet back
Undo the 3 X M6 bolts and 1 X nut, securing the tin cover.

Undo the M6 nuts securing the ecu and release the 3 (or 4) electrical connectors and remove.

To open the ecu case, undo the small phillips head screws on both sides

 

id disconnect the battery and leave for about 10 mins before hand

 

thanks gents that was mighty quick reply...thats what i like about scoobynet it's like havinge your personal mechanic beside you.

 

No need to disconnect the battery.

 

Hows that then chap?? Is that safe??

 

I've probably changed over 100 ecus without disconnecting the battery, and never had an issue (yet) -

If you don't disconnect the battery before removing your ecu, and it decides to **** itself, don't blame me

 

Madboy!!! hahahahahaha! Fair enough!

 

Why would you want to do that? As Fiestaboy has already said there are no components in the ECU anywhere near sensitive enough to suffer as a result of the connectors simply being removed with the standby battery power still running into it.
