Apologies if this is common knowledge but I learn't a little more about this engine today from technician Dan at KH. Anyone who has driven the 3.7 Roadster may have noticed that throttle response is slow when taking your foot off, such that revs are held onto a tad too long. This manifests as an undesirable kick when up shifting anything other than slowly, especially with the wider ratio's
I thought it was just a characteristic you had to learn to live with but apparently its a spin off of ECU mapping for the automatic version of the Mustang. MMC are aware and have corrected by re-mapping on ARV6 but as this messes with emissions have not offered it to standard Roadster owners.
Dan is working on being able to offer this tweak in the future
