As the title suggests, does anyone know what a std RS4 should be producing in terms of g/s airflow and boost if I log via VAG-COM?

TIA.

I'd check for you but my laptop battery is goosed!

Cheers Patrick - I called Minhea on Friday - std RS4 should be in the order of 280 -300 g/s. Stage 1 car should be 340-350 g/s.

Nige.

The highest g/s reading I have for a modified RS4 is 364 g/s. No stock data, and due to way the code works the boost values are not relevant.

Phil, what do you mean boost values are not relevant??? The boost values you log in block 115 are the boost values measured by the MAP sensor before the throttle body, so really I don't understand the point you're trying to make.

The highest MAF reading you'll get with VAG-Com is 364.08g/s and this is only due to the data being read out of the ECU as scaled 8-bit values. The ECU can read much more and there's other ways of reading the airflow accurately

HTH,

Mihnea

When actual is higher than requested.

Having migrated from slightly modded B5 S4 to B5 RS4 very recently as well as becoming a VAGCOM junkie I'd be keen to see some stock RS4 logs for blocks 003 and 115 if anyone has them.

There are only two or three RS4's here in the western antipodes and less than 50 all up downunder so access to data from Ol' Blighty very welcome.

Cheers
