After losing the season time trial, and being outpulled by three car lengths on each straightaway by two competitors which were dyno tuned and chipped by us three weeks prior , this car was brought to us to also be live mapped, the result being the following. The engine is a stock US motor with racing headers and an open exhaust. Max power between 5000 and 7000 rpm is most important as this is the operation range of this track motor. With the red curves being a dyno run with a stock 87 Carrera chip, and the green power curves with the car's previous performance chip, the blue curves show the resultant engine power after we live mapped a custom chip on the dyno. Compared to the previous chip, at 6200 rpm, the motor has gained 17 hp at the wheels (20 hp at the engine) and at 6800 rpm, the motor has gained an astounding 40 hp at the wheels (47 hp at the engine)! Had this car been chipped by us earlier, he just may have won the time trial, which was lost by half a second. When everything counts ..... !

Here is another '93 RSA that we dynoed and live mapped on a Dynojet 248x. The engine has been modified with some cams along with a set of headers, mufflers and a lightweight flywheel. With the stock chip, the engine dynos a max of 229 hp, or 270 at the engine factoring a 15% drivetrain loss (blue curves). However, the engine has become excessively lean after 4500 rpm, with a dramatic drop in power after 5500 rpm. After a custom remap delivering the proper amount of fuel and correcting the stalling from the lightweight flywheel, a program was developed for use with 91 octane street gas, and 100+ octane race fuel. On 91 octane, the engine now develops 246 hp at the wheels, or 290 hp at the engine (green curves), and with race fuel, 260 hp at the wheels, or 306 hp at the engine (red curves). At 6300 rpm, the engine has gained 85 rwhp, or 100 hp at the engine with race fuel!
