HSV XU6 W2A intercooled Tune and log

Post by 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.

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.
