By default the Ecuload logging only goes up to 160, despite the ecu being able to see up to 200 ecuload. How much boost is this? The following table is a rough guide (credit Merlin, Evo X tuning guide): Boost vs EcuLoad So the Rcolt Ecu can only see up to 200 load (about 17-18 psi depending on mods). This means any map in the rcolt ecu that goes past 200 load will not be used by the ecu, instead it will use the 200 load column (fuel, ignition, mivec etc).

Before we get into that, some more background. ECU Load is only 1 byte load. To log it, only one MUT [...]
