Had a link on my skyline and cossie brilliant ecu for the money did everything well and easy to use cold start worked really well throttle transient was really good plenty of load sites to accomadate big power . Can really only see the worth in buying a syvecs or life is for more complicated setups like heat management turbo speed along with multiple throttle control . Steady mapped mine due to the resemblance to vipec and will quite happily manage a 700 bhp road track car but the emtron what mark has now is probably a great competitor for the above ecu . The link ecu I think is actually under priced for what it is imo
