SDS vs EEC Dynotest
Our tester was Wayne's Capri, a street driven drag car with a 351W and Procharger making a mild 7lbs of boost. In EEC form a A9L computer was used with a Motorsport Rev Extender that allowed us to raise the rev limit and adjust the air / fuel ratio. A Pro-M 77 meter was used calibrated to the 30lb injectors and the Procharger FMU was retained.
For the SDS test we replaced the injectors with larger 42lb and removed the FMU as the SDS can more accurately control fuel enrichment under boost.
Testing was done on a Dynojet Chassis Dyno, all figures are at the rear wheels, corrected for altitude and temperature.
The results are clear, the SDS made more horsepower and torque across the rpm range with big gains in the upper rpm's where the MAF meter becomes a restriction. Street driveablity is much better with the WMS / SDS Programmable Injection installed.
Some track testing was done after installation of the SDS although a full pass could not be made as Wayne doesn't have the necessary safety equipment. The track officials allowed one top end pass after rolling out 100 feet, the result was 126 mph. They then let him try an 1/8th mile pass and he ripped on an impressive 7.0 at 99.8 mph, should be good for low 10's in Calgary - remember we're at 3800 ft.
