Hello all and thank you for reading. So I drove the car a few times around the neighborhood and this is what I noticed. When pushing the throttle down It would move about 10% before any response. The acceleration seemed less than impressive and after driving the car for about five minutes it would begin to have a jerky feeling, loss of power and then no power at all. I shut off the car waited a few minutes and then would start driving again. I wouldn't get very far and have to again shut off the car and wait a few minutes. I got the car home and now I have no throttle response.

Another item I noticed was very little Regen

Large drive unit, 16 model S battery modules

Please see screenshots of current parameters.

Any suggestions would be much appreciated

You've flashed the FOC software for synchronous motors. I'm surprised there is any movement at all.
Go back to stm32_sine.bin and find the correct parameters here: https://openinverter.org/parameters/view.html?id=16

Apart from that, is your coolant circulating ok?

Thank you Johu I appreciate the quick response! Your help got me to the car show I was attending this morning.

I noticed the car is still underrated when giving full acceleration. Definitely not the snappy torque one would expect. I took some new screenshots of the current parameters. I believe I went through everything and adjusted as you described. Am I missing something?

Also I don't see the setting to select "aggressive" as shown in your reply.

Again I want to thank you what a huge help and sigh of relief.

So I'm doing some more reading and I flashed the most recent version however I don't believe that is the update you were recommending. I'm going to flash the 4.97.R-Sine. I believe this my mistake

Great to hear
Sorry that the parameters are somewhat old. Generally the latest version is said to perform better.

For all other tuning the Tesla aficionados need to chime in

Check the voltage sag when accelerating. If it drops a lot with wide open throttle, there might be faulty module. LDU does not give much power when voltage drops below 240V.

Thanks I'll check that
