Digital Fuel Adjuster
Ref: High Performance Electronic Project for Cars – Silicon Chip Publications.
This unit is a huge revolution in DIY automotive performance. It gives you the power to completely tune the air/fuel ratio throughout the entire load range, at 128 load points, providing incredible mapping resolution and brilliant drivability. It uses the Handheld Digital Controller – KC5386, so there is no need for a laptop, and it supports both static and real-time mapping. It can be used on 0-5V and 0-12V signals, so it is compatible with all voltage output airflow meters and MAP sensors. It can also be set to work with 0-1V signals, allowing modification of EGO sensor signals. This unit has been extensively tested on a wide range of cars including Subaru Impreza WRX and STi, Nissan 200SX, BMW 735i, Lexus LS400, and Nissan Maxima. Kit supplied with PCB, machined case, and all electronic components. Kit requires the Handheld Digital Controller – KC5386.

Interesting... sounds straightforward. What does "static" and "real-time"mean? open loop and closed loop? A 128 cell map is a bit small (if I am thinking straight, I am comparing to the UTECs ~300 through 7000RPM). Also, and I think this would be an easy feature to add is a TPS crossover, or MAP crossover, to let the ECU handle idle and low loads as the UTEC does. Makes tuning much easier. This would be a great addition to an MBC.

I think static in this case means idle. I know it wouldn't be a complete standalone, but I imagine that it wouldn't be that broad of a step for it to completely assume fueling duties.
I think I may give Jaycar a call later this week.

I'm thinking about swapping my 2.0 into an RS I just bought. If I do, I'm thinking that I'd throwing some pistons and strap on the VF30. If so, I may just try this and then utilize a hallman MBC and then figure out how to control timing for $20 or so.
