32 bit ecuYeah, the problem isn't with accuracy in the logger or the quality of what the ECU reports. The only caveat is if you are logging a bunch of stuff the lag between data points can be an issue (especially with 16 bit ECUs). The old style OEM O2 sensor was worthless at WOT and the new one isn't worthwhile either I don't think. There also isn't any good EGT sensor. For boost most people consider what the ECU reports to be the best source.
