it looks like it would be hard to connect to my computer controlled car,
what octane equivalent is the wood gas ? anyone have fuel maps for it ?
Old cars will take this technology better:

I'm no expert on woodgas, but I suspect the power output dynamics of woodgas which is a complex and variable mixture of gasses does not equate well to being expressed as an octane rating.
This Site says:
Assuming that the engine modifications described above are correctly implemented, decrease in maximum power output of petrol engines without turbo or supercharging can be limited to about 30 percent. Turbo or supercharged combustion running engines on producer gas can have power outputs equal to those in petrol operation.
Forced induction will give more power - But I'm assuming would use more fuel.
Megasquirt would be worth investigating if you're interested in fuel injection, although I suspect carbs would be more appropriately low tech for Doomer transport like this
