Title: VVT Maps MED 9.1 K03 to K04
Post by: BetePaille on January 16, 2026, 09:54:28 AM
Hi,
is this the correct VVT map used at normal condition on K04 cars ? You simply paste them in case of a K04 conversion on a BGB engine or the camshafts are differents ? Are there benefits to modify them further or are these optimal for max power/efficiency even at max tuned boost ?
Thanks!

hi,cams are different from a 197ps engine to a 265ps (eg. S3) this is not correct to copy and paste the values from what i know,i might be wrong but it s kind of logic,you should adjust according use those maps as starting point and correct from there, log:

load

actual cam position vs target

egt / knock

maf

then fine-tune VVT  especially above 4000 rpm
