Re: Extremely low power and poor pedal performance

Yes just changed udcmin to 200. The car now has much more power.

Any recommendations on giving the pedal a different set of parameters

Re: Extremely low power and poor pedal performance

Zieg I just tested the pedal again and that is what I'm seeing. Maybe I'm doing something wrong however I was following the instructions for pedal calibration

Extremely low power and poor pedal performance

Good day all! I am having an issue with my conversion. I have a Tesla LDU and 16 Tesla model S battery modules. When placing the car in drive and applying pressure to the accelerator I have noticed it has a significant dead space. As the pedal is depressed the vehicle does not move until the pedal i...

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

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 we...

Help with parameters! Lost throttle and lost power

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 b...

Open inverter LDU. Low acceleration

Want to thank everyone in the forum for your help!

I took my first drive recently and when giving full acceleration the car didn't drive any faster. I maintained appropriately 5-10mph
It's as if the car is in limp mode. What parameters should I be looking for? Any suggestions?

Re: Contactor Control

Maybe I wasn't clear in my explanation. I am referring to just key on power. The vehicle is in neutral.

Question ❓ I have the Simpbms and simp charge running in my EV conversion. I am also using the open inverter with LDU. I was controlling the contactors with the inverter and was advised it may be a good idea to control the contactors with the Simpbms. I ran key on power to the simp J5 connector pin ...

Re: LDU board first time setup questions

Thank you for the response and helpful information! We are using two 12 volt batteries in series to spin the motor. We wired everything up and double checked all connections. When we turn on the 12v power we hear the contactors open. After a second or two the voltage drops to zero. What would cause ...
