Custom diff map for Subaru with Motec M1 or diff controller from 2010 onwards , written and developed by Hayden Paddon. Used by Hayden in 2011 to win PWRC and more recently by Andy Martin and Jeff Ward in NZRC. Maps written to encourage a car more front positive and to try and help keep car straighter on exits. 5 different maps loaded onto Diff controller with variations/options from base map so can be adjusted by driver during events for different driving styles/road conditions. Your Motec diff controller must be sent to PRG for maps to be uploaded.
