I have wondered how feasible this approach is on any modern-ish car. To what extent are things like abs, traction control etc built into the engine ecu. Or immobilisers and alarms not to mention instruments.
It's tricky/impossible to do it with a stock manufacturer's ECU, but it can be done with an aftermarket system like Omex or MBE and a custom engine loom. Not a trivial undertaking, but not beyond the realms of possibility especially with a well-known engine.
