As part of the VR30TT series development EcuTek has developed an example ROM for the EU Q50RS. Testing has revealed the best methods to achieve reasonable gains without large risks. The end result of our testing was the creation of a series of Example ROMs that would give the tuner the basic modifications to the ROM that increase horsepower and remove the limits. This Q50RS ROM file (6HF2D-34204-exampleROM-enc.bin) should be used as a guide to tune from and any "self tunes" should be based on this ROM.
Results and Map Changes
The example ROM with a scorpion exhaust gained 100lbs.ft torque and roughly 60hp at the flywheel (453hp 470lbs.ft) over the stock calibration (410hp 375lbs.ft). It uses a combination of increase boost, turbo speed, WG and VVT angle on top of changed fuel and ignition targets to achieve the increase.
The list of maps changes is relatively low to achieve such a gain, below is a ROM compare of a stock and tuned ROM.
Map Changes
Boost Control
Using RaceROMs updated boost control strategy the boost target was raised from 2.0bar (Absolute) to 2.25bar peak and held much higher at higher RPM. there is a map per mode all set the same, however they can be adjusted to suit your customer if required.
TheBoost target max allowed #1and andBoost Controller Maximum was also increased to accommodate the higher boost target
