THE EFFECT OF CAMSHAFT LSA 244,5° AND ECU RE-MAP ON PERFORMANCE ON BBS1 TYPE ENGINE

Abstract

This research was carried out with the aim of finding out whether there was a change in performance if the TPE BBS1 engine camshaft was changed to
244.50 and assisted by re-map electronic controlling unit. This research uses experimental methods. The research object is a motorbike with engine code BBS1. There were 3 test variations tested in this research, namely standard camshaft and standard ECU variations, LSA 244.5o camshaft and standard ECU, LSA 244.5o camshaft coil using an ECU that had been re-mapped. Tests were carried out at the Vehicle, Motorcycle, Test Bench and Alternative Laboratory at the Indonesian Education University using a dynamometer to measure torque and power, as well as a gas analyzer to measure exhaust emissions. The research procedure was carried out with initial measurements of torque, power, fuel consumption, and exhaust emissions with a standard camshaft and standard ECU, then replace the standard camshaft with an LSA 244.5o camshaft and the standard ECU with an ECU that has been re-mapped. After that, re-measure the torque, power and exhaust emissions after replacing the components. The data obtained are maximum torque (N.m), maximum power (HP), exhaust gas emission levels (%), fuel consumption (liters/hour), and volumetric efficiency (%). . There was an increase in torque and power when testing using a dynamometer with each different variable. Based on the calculation using the formula, there is an increase in the volumetric efficiency value of the variable.
