Anyone know the VAG COM measuring blocks for fuel trims?

[Lukey. 381]

Since replacing my maf ive been watching the air mass readings and they are coming into line, which is nice, getting a peak reading right where it should be.

For this i jumped into the measuring blocks and found one that gives me real time g/s readings, but now im trying to find the fuel trim readings, according to rosstechs help docs it should be group 032 but this comes up as N/A on my car.

It said in the help doc that the trims should be percentage readings, i found one that has percentage readings, cant remember which group, maybe somewhere around 15 or 16, but they were all labelled as Lambda, the first block had a fluctuating reading of around -2% to -3%, the second had a solid 0% and the third had another fluctuating reading of around -2% to -3%.

If these are the trims then ive been told that anywhere between -10% to +10% is fine right?

Plus are these the fuel trim values? If not which group should i be looking at?

Cheers

Oh right, does that mean that idle is additive and part load is multiplicative?

if so is it real time reading which is why part load is 0% as the engine was idling?

or is part load zero cos i just fault cleared?

[Lukey. 381]

done it, the blocks were 0% as id fault cleared, driven and logged today and all is fine, and extremely close to perfect :-D
