Re: Tesla LDU Controller Stops Working with Aggressive Throttle

Oh wow. Great resource, but a shame they never made the jump to the database - would really be great to see some more validated setups on there for completeness.

Re: Tesla LDU Controller Stops Working with Aggressive Throttle

It seems that ocurlim value is the same as the current in amps. So, 1000 ocurlim = max 1,000 amps. I set my ocurlim to 1500. I made my own battery using Tesla 18650 cells in a 96s72p configuration made with double Battery Hookup fusible links at the cathode. Given that, I didn't want to exceed the ...

Re: Update via wifi fails

I'm getting many reports about failed updates lately. Really bugs me, especially if people have to take apart their drive train. I plan to change the esp firmware so that a) the update runs autonumously, i.e. not controlled by the browser b) delete the file after update So seeing a lot of great ide...

Re: BMW e39 + Siemens motor + Prius Gen3 OI - Yanoibe39 conversion

10KOhm is orders of magnitude too big. Precharge time is function of how fast you fill your device's capacitors - a high value resistor will slow this current to a trickle at the expense of time. OEM use something in the ballpark of 25 Ohms (yes, 1/400th of your current value). A 33 Ohm 100W unit is...

If the whole connector is Sumitono, the only crimp that seems close to the right pitch for the signal wires is the type 1.0II or 1.0III, which are 1.8mm wide... Hold on... Sumitomo?

Doesn't need to be a "good" one. A perfectly serviceable one (i.e. 0-30V 0-10A) can be found online for under $100.

Dima, I'd like to have a go at running your latest variant of the web interface, but the mklittlefs tool your PS script calls is no longer available, so I'm unable to compile my own .bin for the file system - any chance you have one ready to share?

In before the thread gets shut down ;) Does anyone have an actual quantity for how much gearbox oil should be added to the front SDU?

Just a little note to let people know we have finally been able to source the 2 pin JST connector for the HV interlock and coolant temp sensor so all future opensource boards will be supplied with these connectors fitted.
