Excellent, I wonder what they did? Any change in fuel mileage? It's probably a PID type controller, they may have adjusted it to be less aggressive with the throttle. My '90 Eclipse GSX had a mildly abrupt cruise control, the head of product development at Mitsu told me it was programmed for the non-turbo version, and was giving a bit more throttle than needed. It wasn't nearly as severe as this, and there was no real need to compensate.
Haven't notice the problem on my 05 OBW-XT. Perhaps this problem is the opposite where the cruise was programmed for the turbo models, and affects the non-turbos...?
