I've actually been looking into this a little since joining this
discussion.
I plan, sometime in the near future to tune the Trionic 5 ecu (yes it is
T5.2 1993 ecu but it is still possible) with T5suite.

And in the do***entation, there is mention of E85, and tunning the
injector cycle and ignition timing/advance to run E85 through a
mechanically stock T5, and possibly even T7 car.
On the subject of burned valves etc, unlikley to happen if you do add
sufficient extra fuel which is what I said regarding carb jetting and
adaption ranges. I said don't let it run lean. A standard spark ignition
engine, with sufficient fueling is all you need. Just look at
LPG/Propane systems. Propane is far lower than petrol in calorific
value. It doesn't even need to be accuratley measures, just open the
tap, pour it in, fire the spark, drive. No problems. Again, get it too
lean and it will break the engine. A simple gas tester can sort that
out.
