I think we are ready to share with some early adopters. Classic t4/t3 gems only, so far. Ask @MikeKC about pricing. He is building the kits. I have the parts. Mike can confirm. Except for the 3 phase wires from motor to controller, plug and play. He should post some pictures soon. ---

Pics as promised: Yes the wiring is messy - this is what it looks like when you are testing. Final product will be nice and clean. As you can see the 23pin connector for the T2/T3 plugs into the converter board. Then out to the sevcon controller. Pretty slick setup. Again “Dave is the Man”.

Does pb work? (Parking brake) Turf? Remember that board also transfers the regen function. Useful if we find the trigger in the gem. Map an input and set % torque while braking. ![s-l400-33](https://canada1.discourse-cdn.com/flex030/uploads/electricforum/original/2X/d/d9e1c054522a3017b1df580b987c2403d07e7c3e.jpeg) ---

I think PB will work, but not mapped at this time. Yes Forward/Turf/Reverse working as switched. I think if we just adjust the ramp down settings the regen will be fine. It is working, My personal preference this that it would be a little harder regen, like in my Tesla. ---

I’ll send my file with my preferred regen and D1 later. Don’t give up on Gems. I need someone who can help develop kits. ---

Just sent my current Anvil file. It has nice regen and D1 mode. It should work in Gem with only throttle changes. I think that I mapped the parking brake to Sevcon P20. Have we ever tested the Gem for active low on Gem p13? ---

Hi guys, I have a 2005 EL truck INWO has helped me with, thank you INWO! I just burned up my stock controller, borrowing from another project so I’m still going but I am sure my 100 volt pack and lead foot will be killing my set up by mid summer and I would love to have more then 20 miles range without a battery upgrade. I’m running 6kw ford cmax batts and chargery BMS. I love to tinker, have a lot of electric RC car background but CANBUS and computer programming is way out of my league. I am a bit on the low budget side, this truck is actually my daily driver with lumber rack for half the year and saves a bunch on fuel and maintenance. I’m all in and able to follow directions when there is somewhat of a kit ready. ---

@Matthew_Cotten I think we have a setup just for you 🙂 Read up on the other threads about 8Kw motors. Dave and I can get you hooked up. I can fill you in on all details later but have to run off to a meeting right now. @Inwo ---

Oh man! Thank you Mike! No hurry but I’m completely ready! I will try to get more people with gems on my island interested! 🕶 ---

I’ve also been following for a year now excited to be a part, I just know I have nothing to offer for help in the real work you guys are doing so I have been getting by with my old stock set up and a 24 cell lipo battery pack until I could be a part with my limited knolage. Very excited! Love my truck!🙂 ---

I’ve figured out most of it, I found your PC board kit on ebay and the induction motor at that motorsports place but I still need a programmed Controller and would rather buy all of it from mike and INWO to help as much as I can. I’m hoping Dave has a bunch of induction motor to sell still! ---

@Matthew_Cotten Sorry I have not gotten back to you, busy day with my real job. Yes Dave has plenty of motors/controllers and we can build the boards and program the controllers. Give me a day and I will PM you with all the details and caveats (which you may have already read about). ---

> [@Matthew\_Cotten](#): > > I’m hoping Dave has a bunch of induction motor to sell still! Yes, I do. I prefer to sell a few at a time on a pallet. The boards and controllers are easy to ship. I can build the boards if Mike can’t find the time. I can only bench test them, as I don’t have a classic Gem for testing. ---

Hi, thank you! Sounds like I should start with two motors then as I get more cash(soon) I will purchase the controller and board. No hurry but I’m ready when you are Dave, thank you! ---

It’s p7 that is 0-5v throttle input. [Previous page](https://community.electricforum.com/t/gem-a-c-motor-conversions-8kw-motor/17597.md?page=2) [Next page](https://community.electricforum.com/t/gem-a-c-motor-conversions-8kw-motor/17597.md?page=4)
