Saga Model Incompatibility

When PROTON initially gave us the car, it was a Saga BLM 1.3 model. However for this competition, PROTON then decides to standardise the cars, based on the Saga BLM 1.6 model. Consequently, we received a 1.6 model gearbox with all necessary accompanying parts. Following that, we un-mounted the 1.3 engine and gearbox and installed the new gearbox fitted with the induction motor into the engine bay. During the installation, we have some difficulty putting in the gearbox into the engine bay because the forward mounting part of the gear did not match properly between the chassis and the gearbox. To overcome this we had to modify that part by drilling a new bolt hole.

Besides that, we had other problems, mainly related to the electrical system. Since the car is a 1.3 model and the gearbox is of 1.6 model, there are some electrical incompatibility between both components. Firstly, the speedometer sensor which is an integrated part of the gearbox had 3-pin output instead of 2-pin output for the 1.3 model. So we might have to find an out-of-the-box solution and use a GPS device instead. Another issue is the reverse sensor. Between the two models, both of them have 2-pin output but with different port shape. To solve this we have to change the port from 1.6 model to 1.3 model by cutting the wiring port from the 1.3 model.

Kesian ye, tapi selesai juga masalahnya, thanks bro.
