Problems:
My MDS again is kicking very stiff on the interstate when on cruise control. While in the stock tune I can hear the MDS drone but I never feel the system engage.
Down shifting from 2nd to 1st gear under normal driving (Not using the auto-stick) while stopping seems to "drone" or "hesitate" slightly longer than it seems it should. The car is not stalling and there are no codes associated.
- I saw a post about a "MDS Smooth" adjustment Mike made for a client. Is there something I can do to make that kind of change and what exactly is the cause?
I drive conservative when kids are in the car and spirited when they are not. Functionality of the vehicle is excellent. I have exceeded services and recommendations for the vehicle maintenance. Recently flushed/replaced the tranny fluid and filter, inspected suspension components, replaced sway bar end links and bushings, put on a new belt tensioner and gatorback belt, new plugs (OEM), new brake pads, turned rotors, new tires, etc...
I did reset the TCM Module and lowered the Fan Speeds by 5 on all points for fun. No other changes to the 91 Oct CAI tune was made.
The last time I used the tuner I remember reading in a manual or online a statement like "89 Octane could be used on the 91 Oct Tune". I now see in every discussion I could find that this is not recommended? Thank you.
