We now have a speedometer replacement for any conversion using Smart Bms. ![MVC-001F](https://canada1.discourse-cdn.com/flex030/uploads/electricforum/original/2X/b/bd56288a96f28deb56586eb0a8441dadf5ffeca9.jpeg) This should garner some attention. Your speed may vary. 🙂 ![MVC-002F](https://canada1.discourse-cdn.com/flex030/uploads/electricforum/original/2X/0/0c0bdc9a3260463cac0e41bf10420ba05f5f622e.jpeg) Let’s see if Grant can clean up my gorilla tape install. 178a. Just noticed that. Not bad for 89km/h. ---

What vehicle are you doing 55mph in?? ---

That’s a joke, before I calibrated it. I changed the tire size in app from 1000 to 333 as it was reading 3x actual mph. It states km/h but easily calibrated to read mph or even rpms. Waiting for the battery on my gps speedometer to charge. Then I’ll get an actual reading. I used my last set of encoder plugs, but I can send you the other board when you are ready. I think that you keep the plugs in stock. ---

LOL - I thought for a minute you were trying to give our 60mph record in a GEM car a challenge… Yes, I have Encoder plugs in stock. ---

Dave, that’s the same BMS I have in the '10 eL, right? ---

Yes it is. Is that the one that’s getting the new motor? ---

Yep. The '10 is getting the new ac motor. ---

It would have taken me 1/2 a day here. ☹ I was so close one day. I was testing the conversion pcb, and it would have only taken the motor swap. But then you would have missed all the fun. 🙂 ---

Heck, I’m just pissed at myself for not thinking about it earlier and asking you to to just put the 8kw motor in a box in the cab before John picked it up.
