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

Re: Help with parameters! Lost throttle and lost power
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?

Re: Help with parameters! Lost throttle and lost power
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.

Re: Help with parameters! Lost throttle and lost power
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 ![Smile :)](./images/smilies/icon_e_smile.png)
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

Re: Help with parameters! Lost throttle and lost power
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.
