Can I use DeltaDash on a car with a UniChip or other piggy back style ECUs ?
Yes you can. However, you must bear in mind what a ‘piggy back’ module does. A ‘piggy back’ ECU works by altering the signals that go in and out of the ECU – it may change sensor voltages, such as lambda, or boost sensors, in order to get the standard ECU to behave differently. The module may also Alter outputs from the ECU, such as adding or removing ignition timing advance or fuel. Because of this, some of the values read from DeltaDash may not represent the current state of your engine – they are the values that the ECU is using, but may not all apply ‘as-is’ to the real world.
