Ok we did some testing today at Imagine Auto with the dyno to see the results of flashing the car. I installed the latest flash client and scott sent me a tuning file for my car with a number of features, 3000 rpm higher redline, O2 sensitivity fixed, and of course fuel maps all the way to 100 octane. We saved my existing flash previously. We ran the car up on the dyno for a couple of runs and established a baseline for my car. We then turned the car off and I attached the battery charger to the car's battery (safety measure) and attached the USB / OBDII cable to the car and to my laptop. Laptop was plugged into power outlet (safety measure). I simply double-clicked on the new file and the software launched and gave me some messages, confirmed some items and with my approval began the flash. About 5-6 minutes later the flash completed, the ignition turned off, laptop and cable disconnected.
Then we started the car up and did a dyno run. Our results were 4hp less than my previous GIAC-based tuning. Ok not bad, but not great so I called Scott. Scott told me that the ECU would now be able to adjust for the conditions it sees all the way up to 100 octane but that with the Porsche DME it adjusts downwards quickly and upwards slowly, he suggested we try some more runs and see what happens as it begins to adapt. We ran the car a 2nd time and gained 2hp so only 2hp down. We then ran a 3rd time and were now even with the GIAC HP results. That was all that they had time for so if additional adjustment takes place it is possible that the results may go up further, but at this point I'm comfortable saying that the results are as good as GIAC when it comes to HP/Torque numbers.
After we were done with the 3rd run I noticed 2 things:
1) The flash had turned the A/C on, and the dyno operator had not turned it off. The initial GIAC baseline runs we did had the A/C off, so there is some possibility that the A/C on was dragging the
Softronic numbers down a little.
2) With the raised redline the HP peak has shifted up to around 7100 rpm as opposed to 6900 rpm.
So all in all I'm pleased and the flash passed with flying colors thus far!
