The problem is that our stock Mitsubishi ECUs (at least everything before the EVO X) uses an entirely different driver circuitry. So the numbers collected on many of these standard flow testing stations for injector deadtime really have no bearing for our factory ECUs. | The problem is that our stock Mitsubishi ECUs (at least everything before the EVO X) uses an entirely different driver circuitry.
