Rothsport Racing in Tualatin, Oregon just replaced the old Zytech ECU for my RS America with a DTA S80 PRO ECU. The goal was to get a flexible ECU in there that was tunable for different map settings. The Zytech is fairly preshistoric. One of the goals was to get it "de-tuned" to run on 92 octane pump gas. The result is 344hp at the crank on 92 octane. Previously the Zytech was mapped to run on 100 unleaded, with a recent dyno of 315 at wheels. The 3.8 motor was built by Bob Holcombe at Motorsport Design in the 1990s, but hasn't been run much since then.

Here is a video of the Rothsport dyno on pump gas. Not really exciting, but I thought I would post here on the 964 forum to some more action out here!

impressive, just reviewed their detailed website and tuning/monitoring capabilities of this "tuner chip" - very impressive.
is the rothsport pro shop generally using this or the s100 for their "pro tunes"?
