We are pleased to announce that the tuning program for the Corsa E VXR has begun.
Stephan Klasen (our mapping engineer) has purchased a Corsa E VXR in ‘Shiny Rock’ Grey for a whole host of development work to compliment further existing on-going development on our own Astra J VXR, as the Corsa E shares the same GM – Delphi ECU with the Astra J VXR.
So far we have completed Stage 1 which is just a bespoke ecu remap to the standard car with full rolling road set up and optimisation and Stage 1.5 which has the addition of a front pipe complimented by the bespoke ecu remap.
The car had a number of runs to bench mark its base power as delivered from Opel. With the engine fresh out of the box and with less than 100 kilometres on the clock the standard power was recorded at 203 bhp and 208 lbs ft of torque. Following Stage 1 remapping the power increased to 223 bhp with 237 lbs ft of torque. As you can see from the graphs below this power and torque increase is across the whole of the rev range right up to the standard rev limiter.
A change of front pipe and the car was put back on the dyno. Following a good amount of recalibration and load testing runs the power further increased to 237 bhp and 238 lbs ft of torque. At this time Stephan wants to keep the toque at this level for the safety of the pistons. You can see from the Stage 1.5 graphs the rev limit has also been increased to complement its improved breathing and this the shift light function has also been lifted.
A full exhaust system has now been fitted to the car and mapping work for this will continue as soon as the car arrives back from KW who are currently using the car for suspension development; Watch this space……..
