We have 6 Beta cars around the globe testing this STG2 software, many of which are driven hard on track. We don’t tend to do much drag strip work, as you could tune specifically for a drag time, whereas we focus on the over-all package of a drivers car. The majority of tuning development has been done at Bruntingthorpe, so there’s a 1.8 mile straight where the Focus RS can achieve around 170MPH, to put that into perspective, a STG3 300bhp Fiesta ST can acheive around 155-160MPH, before having to brake for the right hander. The latest bit of testing at Bruntingthorpe was testing the overall STG2 Revo Package which includes the Revo Intercooler, Revo Charge and Throttle Pipes, Revo Induction Kit(Carbon Fibre) accompanied with a Milltek sports-cat, we were doing 3-4-5th gear pulls to see how the hardware coped with on the road driving, as well as long 6th gear pulls from 1500RPM til 6000RPM (165-170MPH or so) to stress test the entire vehicle, see how the IAT and EGT coped and affected the power of the vehicle and whether any adjustments had to be made to the software to ensure everything was still safe. We don’t tune on the dyno, we just use it as a tool to see how the power curve is looking, most of the development is done on the road as this is where you will be driving your cars, or at Bruntingthorpe if we need a safe environment for high speed testing. We also make our own logging software, so if there is a sensor on the Focus RS, or a table/byte inside the ECU, we can log it, I think it’s over 28,000 different parameters or sensors that we can log, this is our biggest part of development.
This software, or a derivative of it, has been with our dealer network, for around 8-9 months now, as Ford Fair finished last year, the following week, STG2 development started and has been on-going since, much to many of our customers dismay.
