When far enough along you could do a kickstarter campaign to monetize this / fund the last mile of development. Those campaigns define different support levels where people get different benefits for spending different amounts of money. Maybe one level is end-users of a common FI setup (CTSC) who would receive an ECU tuned toward their package, another level for tuners/vendors (folks like LoveFab, Driving Ambition, SOS) where they would get use of your tools and training to be able to tune the OEM ECU, etc. Someone who showed up with enough dough (aftermarket ECU manufacturer) could buy the complete definition, all the data, source to any/all of your related code, etc and be able to productize themselves in some way. I'm not sure what makes sense. The big thing that would keep a kickstarted campaign from working is that people are essentially giving you money now with promise of something in future. There is some risk in that for the supporters...and supporting this could be more expensive than the average kickstarter idea while having a high degree of complexity (risk it won't happen) and relatively low volume (more of a concern for you).
Since the bulk of what is needed is your labor...not huge cash outlays for manufacturing or such...it may not be a good fit. You could just ask for money when you have things in-hand to offer, instead of selling things that you might be able to deliver in the future.
Anyway, the holy grail for me and what I would be willing to pay for, as a mainstream CTSC owner, is an OEM ECU tuned with appropriate maps for boost conditions using larger injectors (RDX?) at stock fuel-rail pressures (or at least a more-resonable fixed pressure). The current solutions (rising-rate FPR, voltage clamp on MAP signal, piggy-backs, AEM EMS, etc) are enough in the non-optimal range to create a void that you could fill. Obviously not all CTSCs are the same with different blowers (whipple, autorotor) having been offered, different diameter pulleys, and different things changed by owners later on (different fuel pumps), etc.
Anyway, really cool progress. Exciting to see.
