I've been searching around the forum looking for a tuning solution for the 5.2 brain, something similar to EFI Live the GM boys use. In recent years the Porsche 928 computer was "cracked" by a company in Europe call JDSPorsche.com (more specifically a man named John Speake). Similar products are also available for the 944 / 951 cars (I'm sure the 911 too, I'm not really involved with those cars). I was hoping something similar was available for the 355's. We do all of our live tuning on a load dyno, on cars that are 100% stock there are gains to be had, some years more than others. It would be very cool to have similar control over the 5.2 computer. So is it safe to assume the lack of threads on this topic means there is no "live tuning" solution for the 355's? On a side note, has anyone ever tried a 3rd party ECU with a 355? One of our prototype 928's is running Autronic on a 32V 5-liter with 30psi delivered via Procharger supercharger. This system allows individual tuning for each cylinder for both air / fuel and timing. The air fuel is dialed in on this car with the use of eight wideband O2 sensors, one per cylinder. A setup like this would completely eliminate the MAF on the 355 5.2.
