l-jet conversion to custom ECU

[fusername]

So I plan on going back to l-jet efi on my bus real soon, namely as soon as I buy it. I have an engine built up with a marginally higher CR and soon to have a 9550 cam in it. I am going to run the l-jet, but i have a second spare l-jet computer than i want to gut and put a home made ECU inside of to play with tuning it, maybe even go closed loop eventually. I would keep the FI stock at first, but eventually replace the AFM with a hotwire and some hose to put the intake outside the engine bay for a cheap snorkle setup. (baja bus!)

has anyone ever done this before? Any obvious problems with this design?

with the cheapness of parts, and my hate for vac leaks, I would cap the FPR and have a constant pressure system, but use a pressure transducer to monitor pressure and compensate with the fuel mapping. I would basically have all factory replacement parts up to the TB. eventually I would love to loose the S boot and associate problems with all its connected hoses, seeing as how most of it is NLA.
