Sounds great and does seem to shift! 230HP seems like a lot to get out of that 1.6. I've got a Cooper S myself but sceptical about remapping it in case of reliability issues with the N18. I presume no issues so far?
you guys need to see what people have done with N14 here in brazil, i have a peugeot 308 with N14 165, tuned to 240whp with AT6 gearbox (almost 300hp on engine) about 1 year no issues at all
Old comment I know, but it depends more on what model of each you have. They made a base model, S model, and John Cooper works model for every year car, and a few special version models here and there like the GP. The base models have no turbo/ supercharger, the S models had a supercharger in the first gen, all following generations have a turbocharger, and the John Cooper Works have a bigger turbo with an engine that makes even more hp than the S.
