ECU tuning - flashing and re-chipping

[pauljh]

Hi all


I'm trying to understand Note 2 of Section 13-1 of the In-Service certification (WoF & CoF):

Note 2

LVV certification is always required for the fitting of a supercharger or turbocharger as a modification, or the upgrading of a supercharger, turbo or wastegate, or the re-chipping of electronic engine control units on turbo vehicles.

What is the precise definition of re-chipping used here?  Is it restricted to physical replacement or modification of the ECU or does it also include software-only changes like aftermarket fuel and ignition maps?

TIA, Paul

Hi Paul,

Yes a remap / reflash (etc) of a chip achieves the same end result as replacement of a chip, so would have the same outcome that a LVV Cert would be required.
