No, It's 1212 as noted above.

For those maybe following -- I uploaded 5.35.R stm32_sine.bin per johu direction. I updated two parameters: potmin to 1200 and maxregentravelhz to 100. Vehicle launch now feels normal and my regen is tuned to where I like it (feels like a normal IC engine at coast down). I believe my controller fine ...

My current firmware is 5.12.R-sine. The wifi interface says to use STM32_SINE/foc.bin. That file does not exist. So, which file do I upload for 5.35.R -- STM32_sine.bin or STM32_FOC.bin?

Thanks. I don't want to screw this up. I'm not sure how to download the new firmware file and upload to my controller. I went to your github, but not sure what file to download. Also, by setting my throttle potmin to 400 I was able to get great launch (tip in from zero speed), but lost my regen. My ...

I've been driving my EV Conversion for the past year and still have one remaining controller issue that I just can't seem to get right. If I set up the parameters for throttle-off regen, I have an intial throttle no response for about the first 20% of tip-in. If I set up for immediate response with ...

Interesting. There doesn't seem to be any impact when I change idcmax. I have it lowered at 500 and the motor still draws current easily in excess of 1400a. Any ideas? If it ever stops raining in norther Michigan, I will continue testing. I see that I can change iacmax. It is currently at 5000 ...

What happens when it reaches this level? Is it like a valve that restricts it beyond this value or does the relay kickout?

OK. Good to know. I will update my idcmax parameter. If I want to limit it to 1400, do I set the value at 1400? Thx.

Thanks. Will try it.

Awesome! That looks really clean!

What batteries are you using?

Also, did the LDU work with the stock rear suspension? I had looked at various Corvette suspensions for my build and was concerned about it fitting. EDIT: I watched the video and answered my own question.

I'd love to see build ...

Now I understand how people feel who say "I can't get my head around the software part"

I can't get my head around the mechanical part. I wouldn't deem something like this even possible. And you just present it like "look it's done!" :)

My education ...

I recently completed (of course, never really done) my Corvette conversion using a Tesla LDU with the openinverter board.


I'm uploading monthly to my YouTube channel -- https://youtube.com/@e-grandpa9778?si=lKo2O2nWbbQaJuvP -- to spread out my build process.

I've read through the various posts, but still not sure how to solve my throttle issue with my Tesla LDU Sport motor with a car weight of 3,600#. I like my idlemode off for now. I don't like that I have to tip into the throttle 20% to get the car to move. I'm used to it, but when others drive it ...

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 ...

If someone knows the recommended ocurlim for the Tesla Sport LDU that would be great. My worst fear is setting it too high and causing the inverter to sink too much current before ocurlim trips.

Is there a correlation between ocurlim and actual current amount? Also, what do I have to do to detune. Looking for of course a good balance. I did change the trip setting to 1 after you mentioned it. thx

Put ocurlim to 2000. That seems to have been the issue. Works great. I will test some more. Thanks for the help!!

Here is my parameter file --

That's exactly what mine is doing as well. Sorry I didn't see your post. I'm only into the test mode for a few days. Other than this issue, the controller seems to work fine. I converted a 2008 Corvette so there's considerable expectations / pressure to achieve an appropriate acceleration rate :). I ...

My conversion is up and running. I'm using the equivalent of a Tesla Model S Sport motor with a 96s72p LI 400v battery (essentially the same as a Tesla S 85). I have tuned the throttle and reg. They seem fine and were close already. However, I can get the main HV contactor to turn off with an very ...

No damage done. After calming down I double checked everything and found a loose low voltage ground to the LDU control.

I accidently reversed my HV polarity going to my contactors during my last bench test using only 36v. The precharge relay and ignition contactor activated, but It almost immediately blew a high current fuse. After discovering my stupid mistake, the system will no longer startup and activate the ...

Thanks for the quick input. CAN is currently a large unknown for me. So, for now I believe my plan will be cruise button toggle on with break pedal switch for off. I'm very interested is using CAN for cruise, but will put that into next steps. Thanks again!

I want to implement cruise Control with my large drive unit. It appears that if I apply voltage to pin 21 it will energize cruise. I assume if I deactivate pin 21 cruise shuts off. Will braking also deactivate and if so which pin? Of course, after the brake is released, I don't want cruise to ...

No current plans for CAN. One thought is to leverage pin 6 when it turns on the main contactor coil.
