Definition of Insanely Tuned

Well after over 500 dyno pulls, ~2500 dyno miles, ~300 tuning files, ~2500 road miles, numerous top speed runs, track events, drag races, etc, etc, etc, etc, the final 997TT EVT700 is nearly complete. I wanted to let you all know the latest developments. Yesterday, John and I spend what looks to be our final day beating our heads against the wall figuring out the quirks of the 997TT ECU functions. I can assure you that there is no other 997TT performance system on the planet that has more tuning time than this one. The countless time we spent is not because we are not knowledgeable about the car or the tuning, it is because we would not settle for the "industry standard" MEDIOCRITY. If we were marketing this kit in Europe, where the fuel is 98 octane at the pump or here in the USA as a "race"100+ octane system, the tuning would have been completed 4 months ago. We have spent 98% of our time getting this car to perform flawlessly and consistently on our pump fuel in our desert climate.

Consistency is the key to the flawlessness. The car can make decent power while making cold power runs. The difference between the power from run 1 (cold) to run 2 (warm) to run 3 (hot) could vary 100 wheel HP. We have seen this time and time again with the lower grade fuels. Our goal for 4 months was to make nearly the same amount of power and torque for all runs including 2 additional hot power runs consistently. Granted, the conditions in our dyno cell are not ideal in terms of exact road simulation, however if we could achieve our goal in simulation, the road power should be greater than the dyno power. Those of you who have witnessed the madness over the past 4 months, know only a portion of insanity that was going on in my head. I made up a whole new vocabulary of words to call this car. After the cursing, I found myself talking to it like it wanted to listen to me. Ha, it laughed at John and I day after day, week after week, month after month. There was a period of 3 weeks and nearly 100 files that we tested which we started and ended up in the same place. We started from scratch 4 different times and ended back at ground zero. After many translations from babble fish as well as help from my German friend, who assisted with translating nearly 3000 look up tables to find the ones that would ultimately help cure the inconstant power, we found the proper recipe that brought all of the work together . At this point, I can read and translate German, I am writing a new vulgar vocabulary book, my co workers confirmed my insanity, I dream about green and black computer screens, I have been called stubborn bastard who never gives up, I have many new gray hairs, oh yea we will be officially launching the EVT700 with EVOMSit "intelligent tuning" software. Thank you for your patience!!!!!!!!!!!!!!!!!!!
