Motorcycle Test Bench Tuning Custom Mapping
Retune the injection system, create a new mapping, chip tuning but how?
a) A permanently installed additional module
The advantage: The original periphery remains untouched. As soon as the module is removed again, the original condition is reached again. The disadvantage: The costs of the additional equipment, as well as its installation, are higher.
b) Direct access to the original control unit.
The advantage: The possibilities for modifications are usually greater. Additional devices like exhaust flaps, lambda probe, secondary air system, etc. can usually be deactivated. The disadvantage: To return to the original state, the ECU must be reprogrammed (reset) again.
Individual tuning
For individual map creation, the mixture composition is measured by means of a lambda probe in the exhaust and corrected to the optimum values. This is usually done every 250 rpm, as well as at the various throttle positions 2, 5, 10, 20, 40, 60, 80 and 100%. The power gain is usually 5-15 hp in the top-end power and up to 20 hp in the lower and middle throttle and rpm ranges, depending on how well or poorly the original map was designed.
We always use cylinder-selective tuning. This is the perfect form of map generation. Here, the individual cylinders are tuned independently of each other. For a two-cylinder engine as an example, this means 2 completely independently written maps. For this it is necessary to install taps for lambda measurement in each manifold. We do this by means of small 6mm threaded inserts, which are mounted in the exhaust manifolds at a location that is as invisible as possible. The exhaust gas is then sucked through a high temperature hose with powerful pumps to the lambda probes of the Dynojet dynamometer. For various models, an additional power increase of another 5 - 6 hp can be achieved, the engine run and throttle response becomes even smoother and rounder.
