Thanks for the helpful question. The answer is a long and unrelated story and the punkin actually found its way into the BWTM page of Autoweek last year.

Hydra now talks to the AiM dash, which is pretty cool - I get IAT, coolant temp, rpm, lambda and more on the dash with nothing but the single RS232 input to the dash. I know it is old-school serial data, but it never ceases to amaze me when it actually works, like every time an airplane actually flies.

Misc electrical projects are to wire in warning lamps for alt, ABS, brake, etc from the soon-to-be-set-aside stock dash, switchgear to turn on dash independent of ignition, run heat soak pump, then to figure out how to adapt variable resistance fuel level to be an analog channel on the dash for a fuel gauge, install and calibrate WBO2. Oh and it would be cool to have the stock wheel speed sensor drive the AiM dash and Hydra, not only for display purposes, but also to enable traction control as a possibilty in the maps.

Then the manifold and oil/water plumbing to the turbo needs to be finally bolted in place with extra adaptors to run the oil pressure gauge and sensor input to the AiM dash.

Then the boost control solenoid and control wiring.

And I am sure I am forgettnig a few other items

When everthing nominally works, I can start cleaning up the rat's nest of wires and tool around the neighborhood trying to get idle and low rpm tuning set up before it goes into the shop to do cosmetics and finish the cage.

lots to do!
