Vehicle 2: B7 A4 Software Shootout

Three software options loaded on a B7 A4 and tested: APR, GIAC, and Revo

NOTE: This software comparison was carried out during the month of February of the year 2006. Since that time each of the three companies has developed improved versions that will be tested in Jeremy's MJB Motorsport 2007 software shootout.

PURPOSE
Conduct data logs and dyno testing of GIAC, REVO, and APR resulting in the most appropriate software for my 2005.5 Audi A4 2.0T.

APPROACH

Conditions:
The data logs were conducted using a Ross Tech vag-com HEX+CAN USB interface with the Turbo button enabled. A Mustang all-wheel-dyno, located at Vivid Racing, was used for the horsepower and torque measurements. Chevron 91 Octane was used through out the whole testing process. Each software flash was on the car for two weeks before it went to the dyno. The fuel pump installed on the car is the "B pump" There are no modifications other than the software. All data logs were measured on the same road going the same direction. The logs were conducted in 3rd gear starting at 2500 RPMs followed by WOT until redline (6800 RPMs).

Software:
GIAC was purchased at Evolution Motorsports, REVO at 20 Valve Tuners, and APR at Billy Boat exhaust. The GIAC was purchased and soon followed by a full refund with no hassles. 20 Valve Tuners also, refunded the full purchase price with no hassles. The APR was purchased since the timed trial would have expired before 2 weeks were reached (they will refund money up to 30 days). APR was tested using the 91 octane program. GIAC was loaded preconfigured for 91 octane. The REVO flash was set with timing at 1 and boost at 6 (set by 20 Valve Tuners).

RESULTS
Air:Fuel - block 31 (calculated by Lambda actual * 14.7)
