1st Jan 70 Hi Andrew, I purchased one of your units before Christmas, carefully fitted it and all is fine (I’m very pleased!). As the car has a DPF, I’m still running the “map”/jumper-settings that were shipped with the unit, i.e. the defaults. I’ve done 2k miles, with the default and without any issue, and now wish to tune a bit-further 😉 Hence, what do you propose would be a good next step for the jumper settings (I’m guessing the default is just 10% but it’d be good if you can confirm?). Many thanks, Simon
