@wonkbreath Yes, but Zeeltronic provide base maps for you to tweak. If you want a decent map you will have to pay a specialist who knows what they are doing. It's not EFI, so getting the fueling right is going to be trial and error. I know the Rob over in Yamaha Skellerns Cheltenham is familiar with the Zeeltronic systems and has tuned Belgarda SP's running them before.
