After some time and early engineering my mate has decided to upgrade the Motor Management System (MMS) from fase II to fase III.
What does this mean? Well, this means many things, such as the ability to save different engine mappings. This means that I will be able to switch easier from gazoline to LPG, or as a matter of fact to Ethanol.
The motorcycle has been test started with brake cleaner to test the trigger wheel. It has started and ran for 20 seconds. (20 second? yes the radiator was not fit, as the trigger wheel take some of the space from the radiator. Some adjustments will have to be done to the radiator).
On the 25th of May the radiator was fitted. The trigger wheel fits nicely (pictures to follow). Now the bike has been started on Gazoline. The bike runs!!! yeahh.
Since we have high expectations and norm, a wide band lambda sensor has replaced the stock sensor. Now the difficult part is to install a CamShaft sensor. I am amazed that the BMW does not come with such as sensor. The wide band Lambda Sensor will allow the MMS to optimise the fuel injection during constant driving situations. A sort of a learning on the go with target to go for the ideal efficient fuel buring situation.
Next step is to drill a hole in the magnezium head of the cylinders. This will be a one chance deal. If we dont get it right we will have to buy a new cover. This will set us back approximately 200 euros.
Now we can start to install the LPG evaporator. connect the LPG injector, connect the throttle house vacuum hose. Fill the tank with LPG, load the mapping and start the engine. If this test works, the bike can than be assembled with the fairing. It will than look as original as before the project.
When the bike will have been completely assembled the software modifications / tuning can start. With all sensors in place, we now have to find the best software combination based on the mechanical capacities of the K1200 4 inline block.

Hoi
BeantwoordenVerwijderenLeuk project. Mijn K1200RS loopt inmiddels op LPG en is door de rdw goedgekeurd (gister).
Ik heb gewerkt met de originele onderdelen waar ik een slave systeem (programeerbare lpg computer) op aangesloten heb. Het loopt al aardig goed maar ik ga nog wel fijnafstellen op een rollerbank. Ook wil ik nog een wideband lambda plaatsen.
