As far as i am aware JUBU are using Syvecs ECUs not Ecumaster ECUs, although both can do DSG boxes. I'd also like to say using any aftermarket product EMU Black or things like a cone filter usually come with a warning "Not for road use" to cover themselves as its not crash tested in the cars and so on, you are in theory changing the cars homologation.

The engine RPM doesn't change because of the final drive/flywheel, your right foot is the deciding factor at what rpm you want to be at. The final drive is there to be an easier way to shorten the gearing so it makes 5th and 6th gear usable on track, we had test cars pound round high speed circuits like Spa or Silverstone and not use 6th gear at all, and with 5th gear being so long it robs you of all acceleration. The final drive should make no difference with daily driving outside a a few extra gear changes and maybe cruising in a higher gear, the flywheel will provide better engine response with little downsides. Our new ultra light flywheel will require a slightly higher idle to keep it smooth.

Lotus Oostende and Komotec purchased a load of us so maybe reach out see what they think

Would an insurer be happy if you changed the OEM ECU either? Its a modification either way. We have proven solutions for the 220 taking it to 270 with just an ECU and a good exhuast. We have 220-300 using injectors, a smaller pulley, charge cooler kit and a thermal gasket and for the 250s we can make 290 easily with just the ECU, probably push 300 with the charge cooler kit and thermal gasket.

We offer an ECU package which will take the 250 to around 290-300. This requires an exhaust swap to a 4-1 manifold. The only changes are the ECU and lambda sensor with our kit. Benefits to our system is you have full flexibility, something you aren't happy with on the map you can change it, you prefer a different traction set up you can change it. Plus it is still compatible with the AIM dash and Ecumaster ADU amongst others if you wished to install one of them as well.

@geartox we recommed the Ecumaster ADU dash as it is just a step above the AIM in terms of flexibility and customization. If you check out RRR Engineering or Ecumaster UK on Facebook you can see the different displays we set up for the Exige. But essentially you can design whatever you want, wherever you want it and whenever you want it to show!
