recently fastened an agu head to a bbu bottom end and put it in a audi a3 running me7.5 it has an ihi turbo that makes ko4 look like a babies toy and bosch green injectors that are period and fittment correct for the agu set up.
the issues im having are theres vvt codes which i am able to map out but i dont know if the actual function of the vvt needs mapping out to correct second issue of car performing like it has a popcorn limiter at 5500 rpm
so iv ditched the ecu it came with got hold of an ori ecu for the car and an ori file to start a fresh map but fell at the first hurddle with the vvt.
any info help etc would be much appreciated

my first though was fuel pump. engine was dyno'd at 396bhp in the ibiza.i never asked what fuel pump it had but surely the standard fuel pump would be no good for an engine running that power.
ill get hold of an uprated fuel pump and try that with the ibiza ecu.
as far as i can see from searching the internet is that the vvt on the a3 was designed to retard cam timing on tick over to lower emissions so it shouldnt be an issue that it isnt there ?.
iv plugged a solenoid into the loom and the vvt code doesnt reappear
