Re: [WIP] [BOAT] Single Seat F2 Race catamaran


Did you remove the dog clutch? Keep the dog clutch and just remove the ability for the EV motor to run in different directions?

Re: Zombieverter Nissan Leaf 160kW

This is a trio of later logs. I held the total torque request (throtmax) back to 60% in an attempt to get a smoother delivery as I struggled to get the power delivery under control and that was making it difficult to drive. it sorta helped but Id changed the propeller and that didn't.

Re: how much power from gen 3 inverter with gen 2 components without battery upgrade?


If you were to use all the components from gen2 leaf (incl 24kwh battery) but upgraded to the gen 3 inverter (either the full 160 kw inverter, or the 110kw with the upgrade board, when that's available) would you be able to get the full 160kw or would you be battery limited?

hope that makes sense ...

Re: Zombieverter Nissan Leaf 160kW


Here is a a log from a 62kwh car

The way the torque gets requested is a bit strange.

So it scales from 0-100 as torque percentage then multiplies by 2047. Given the motor torque is scaled at 0.25 bit/Nm and its a 12bit value.

This would mean 2047*0.25 = 511.75Nm which sounds like ...
