Run by Vauxhall and Opel enthusiasts, we will go the extra mile to give your Vauxhall or Opel that unique touch where other companies are left lacking in choice, bound by off the shelf engine tuning and styling components, we can step in and break those boundaries. Here at A&M Conversions we have teamed up with Steve Greenhall, who we have been working with for 8 years. Steve has been mapping standalone ECU's for 25 years - his expertise and ECU knowledge is 2nd to none. We can map any application from turbo, supercharger, throttle bodies, carburettors etc and we specialise in road and race applications.
