Hello,
Welcome to the Delft University of Technology Racing Team memberspage.
We are a Formula Student Recing team. We compete in the UK and Germany events and we are also present at the Baltic Open event. We are known to build the lightest car in the competition. We were weighed @ 125,5 kg in the UK in 2006.
We are investigating in the VEMS system to use it in the future instead of the MoTeC system.
We are working on a Traction and Launch control system with four wheel speed sensors on the VEMS or with an external system communicating with the VEMS.
Chassis:
Full carbon monoocoque
Engine:
Yamaha wr450 one cylinder.
5 valve cyl head
Power output currently 55 hp with 20 mm restrictor
Current manamgement system: MoTeC M4
36-1 trigger wheel with v/r sensor
1 injector aimed @ the intake valves
Coil on plug ignition coil
5 bar fuel pressure
have a look @ www.dutracing.nl
Best result so far: 2rd overall in the Formula Student UK event. (www.formulastudent.co.uk)
We have a problem with the trigger wheel. It is a 36-1 trigger wheel that worked fine with MoTeC. The RPM reading is too high (700 instead of 550). We cannot check the timing at the moment.
I do not have the configuration file, because the dyno-pc does not have an internet connection.
I have the following settings in megatune:
Rising edge,
Multitooth,
Filtering disabled,
Advanced filtering disabled,
Special N-1 ENABLED,
Number of teeth on wheel: 35
Trigger tooth: 1
Next trigger tooth: 0
Crank min period: 768 us
The timings percentages are as in the help, 75-150 and 150-250 IIRC
The constant for RPM calc is 12000
