The turbo is much more responsive too. The injectors have been wired in series with a 6.8 Ohm 50W resistor for each injector and a transient protection diode (Zener) has been added to the flyback wire. The total opening time has increased for a given effective pulse width but the accuracy seems to have increased due to more effective flyback control. There is still problems with EGT readings, I will look into that very soon as the car will go on to a dyno in a few weeks and then put into storage for the winter. '''2006-06-11''' The car ran 12.34 sec @ 174 km/h at the "local" dragstrip in PiteƄ, north of Sweden. A very nice result for such a simple setup. 110 kPa boost and very little tuning.
