Preliminary mini-scanner data
Hi,
I recently got a OBD miniscanner for my NHW11 Prius and after fiddling with the RS-232 interface, started capturing some data. My first question being what is the relationship between ICE rpm and fuel consumption:
Now there are open questions about the calibration but one quick observation is the specific fuel consumption really heads south from 3,500 rpm and higher.
I still have a lot of work to do to map the fuel injector timing to actual fuel flow. Also, I need to understand why the ICE max rpm appears to be 4,300, not 4,500. Regardless, it is a start.
