HSV XU6 W2A intercooled Tune and log

[immortality]

Hey guys,

Here is a data log and tune from an VT XU6 we ran up on the dyno.

Haven't got a copy of the dyno results but I'll see If I can get a copy. Made about 201 Rwkw

Tune was done by Robin at Torque Performance. As it turns out, the bin file used is actually a $07 from a VY, that certainly explains why we couldn't get the correct info.

In the log, the power run was done from about 34-44 seconds.

It's running 16 degrees of timing @ WOT and had a bit of knock in the high rpm area (seems excessive).

Engine configuration is L67, 15psi pulley but seeing about 9psi in the manifold after W2A intercooler which consists of 2 MACE mini-coolers stacked, enlarged TB and LS1 maf, Full defillipo exhaust system and 1.97 rockers.

We have suggested to the owner to fit a MAT sensor in the LIM and then a quick retune to suit. Suspect we probably need to pull out some WOT timing too.

Any way, thoughts and suggests welcome.

flatlining on cylair? not enhanced i take it? 15psi should net over 1000cylair.

Yeah i also though cylair would be a bit higher

Yeah, going to change it over to enhanced next time. It's a stock VY tune that has been commanded to go really rich. It's commanding 9.9:1 AFR but on the dyno it was showing about 12:1AFR's.
