ClarityBill Two links to info you seek. https://insideevsforum.com/community/index.php?threads/rpm-comparative-data.4492/ https://insideevsforum.com/community/index.php?threads/hv-only-gas-mileage.4089/page-3#post-45189 We agree to disagree thats all...no harm no foul. I will stand by the data collected on the Clarity I drive...SoC has little to no bearing on engine clutch engagement nor RPM's. I do not have to concern myself with adapting my driving habits to ensure "SoC is this or that" one ioda. By your own admission you have to adapt your driving habits, charging methods etc for the Clarity to perform like you expect. I do not...that should be clear enough. Engine clutch engagement/disengagement is very predictable for the Clarity I drive at 45 to 65 mph. If my findings do not suit your narrative...I'm sorry. I have placed the OBDll device on a friends Clarity for about two weeks and her data is very similar to the other data collected...very few RPM's above 3000. And she drives fast on the interstate. Once comparative data from at least two Clarity's which the owners thinks experiences high revs is obtained...then we can continue this discussion. Pointless otherwise. I look forward to data for comparison purposes...not through a thread. My question remains the same...Is the Clarity I drive normal or abby normal? Dunno As to other data points...Yes I collect 16 total...throttle, load, battery, temps, etc. etc. Thanks again for all the valuable input.
