Ive communicated with Mark of Hilltop, to his credit he answered my emails within hours, but he gave me little real info about what exactly they do.
But they are not offering a comprehensive re flash with all the parameters normally associated with it, their "modification' is fueling only and is quite controversial across multiple forums and brands of bikes.
What he told me;
1. It doesn’t matter whether other people can or cannot remap these ECUs – by thinking about open loop/closed loop and the complexities of Alpha N/TPS mapping etc. you are looking in the wrong direction entirely. Maybe they are too.
2. This is because we don’t do what other people do – they are ‘remappers’, meaning they rework OE software. We are software developers – we write our own engine management software.
3. Triumph bike ECUs are not made by Triumph, and not all of the ECU is available to Triumph.
4. Any sufficiently misunderstood/advanced tech will appear as ‘magic’ to some. There is actually nothing magic about what we do, and – like a lot of elegant solutions – it’s relatively straightforward as a concept. The hard graft bit, which took Geoff many years, was making it work in the real world.
5. We work with a number of race teams in various series, including factory supported teams, and some big name riders. Bikes running our software have won multiple championships. Contractual obligations forbid me from discussing this in any detail but plenty of people have been in our shop when some very big name machines have been in there.
So rather than divulge their secret (some say bogus) process, they have gone to great lengths to guard it, making it invisible and un measurable to dynos. The exception is if you actually take the bike to them . They will do before and after runs on their dyno and give you the charts. I have seen dyno charts for the new locked ECU Street triple. their are no gains in torque or HP at the upper end, significant gains in the lower half and a lot of smoothing, A/F ratio is rich to 3000 RPM, then levels to about 12.5- 13. that's it.
so a fuel management system only, and not measurable to the customer. Not what I originally thought. Seems I don't need it as the Street twins are running rich even after CAT removal. I'm going to wait get some new tires, and do a couple dyno runs to check my A/F, which was my big concern.
