Alex & the 3.6 Unichip:
There is no doubt that the problem was fixed - that's a given.
Alex had to have this problem fixed - or broken rings or worse might have been the result down the line. At the very least he had one weird HP/TQ curve and a loss of both. I see this change as a 'problem fix'.

I don't believe its much of a jump of reason at all to say that there wasn't much improvement in this case. The graphs are virtually parallel all the way until the timing started retardation for the onset of detonation, and pulled back big time right on through the detonation itself and slowly came back 'on' as the detonation faded. I believe that most Cyntex chips do not exhibit this problem.

Now, the problem happened to lie in the heart of the power and torque ranges - there are several detonation areas at which the chip retarded timing - and thus *ultimate* (peak) HP & TQ was suppressed as a result.

Chips in general:
To be fair, thre is no doubt in my mind that Porsche chip maps are optimized for crap gas (worst case scenario at work here), and aftermarket chip maps (esp the reputable and later chip maps) are almost always an improvement. Whether it is 'worth it' $-wise -- is a subjective matter. If you use these chips and DO NOT have a knock sensor, you had better run premium gas 100% of the time.
