The newer 337J driver chip is using a desat resistor of 1k now instead of the 100ohm that the 333J chip used.
I started to use the 337 at work for a job.

I think I considered the 337 but saw something I did not like. Non the less I bet the desat circuit is the same inside the chip and they found the same problems I did so they upped the resistor to limit the current.SjwNz said:
I will look at 337 again though I do remember it was a different pin out. Thanks for the input.

Congratulations Arlo, considering the limits it really rips!
Looks like you've got a bit of salt related cancer to deal with, man I hate rust. On the plus side it's pretty straightforward to deal with compared to the immense task you've already achieved!
What's next?

Wow 
really nice you got it going ! Very cool !
really nice you got it going ! Very cool !Thanks guys I will be getting out of bed in 6 hours to drive to California to see luke Jackson and Maybe Zombies and hang out at leguna sega!
Rust is easy to fix.
I have some settings to tweak and a lot of refining to do but its proven to be a viable project even at 200 phase amps its a fun car. I can't wait for 400 then 600 then 800.......
I'm beside my self... Thanks so much to all that have helped see me thought this.... I don't know where 7C went... but HH and him did a huge part in this particular design and Lebowski as well as a few others have helped me so much....
Time for bed....

Apart from high power and things like that, it also seems to be very smooth and controllable as you drive it out of the garage at the beginning of the movie...
Congratulations, have been following your progress since you were working to spin up colossus with controllers of your own design, definitely scaling up well!!! My 2002 insight just blew it's motor, maybe it's a candidate for the same treatment as your crx! After hearing all you went through to get your car running the wife is begging me to just buy a used leaf and donate the honda to your skunkworks! Once again congrats from olympia wa. 8)
Now at 400 phase amps and 90 battery amps. I will up the battery amps once I have the last couple bugs sorted out to make it allow full throttle at a stall and then I can remove the 100 amp circuit breaker and proceed.
But its getting faster... My math says the phase amps are reduced at 25-30 mph to try to keep the battery amps from climbing to high.

So here is something fun to watch. This is at ~1/2 power.
The phase amps were set to 450 and I could not pin it, I was rolling on the throttle until ~90% throttle.
Also the variable regen is super cool It feels like it can slow the car like nothing when the mechanical brakes don't seem like they will be enough.
All the weight is on the front wheels there is nothing in the trunk and the gas tank is removed.

slavaged drivetrain = couple of hundred bucks
fancy DIY controller = 100s of hours or research and tinkering
Test driving your garage project with squealing tyres without the neighbors complaining = priceless

(EV WIN!) 1000s of hours. Don't worry I'm just taking a brake from this to work on the ipm 4 turn split phase dual controller zero 75-7 in a 170lb with battery drag bike I put together with my old motorcycle mechanics instructor so we can keep the record for highest hp of any zero motor

im pondering the option to buy an older leaf and change out the controller to one like arlo built... is there a full diy kit that anyone can eventually buy possibly in the future?
i wonder what the max kw the stock leaf battery can produce?.

I put a thread together you can use all my files and build your own.steveo said:
Its in my high power Nissan leaf thread.
Once I finish debugging this I will edit the files in the thread.

If you get a LEAF with the "lizard pack" generation cells, either from a warranty swapped old leaf or 2015+ LEAF, they can handle quite a bit of current at least while at a high SOC. Seems perhaps 250-300hp LEAFs should be possible soon using Arlins work.

Wow i really like the sound of this .. 250 - 300hp leaf.. just on a controller swap..
it will be a fraction of the cost of a model 3, Arlin could you give us an idea of the est cost of the controller if i was to build from scratch.. aside from the 100's of hours in your time you most likely spent!
Can wait to see full power the the rusty crx

The IGBTs you want are $400 a pop. You need 6
You need about $670 of stuff to populate the boards incl the $90 current sensors..
You need some sort of cap the leaf cap is amazing I have proven it to have more current handling then the really good ones I linked on the game changer thread.
You need about $100 worth of boards.
You need some custom aluminium or copper made up.
There will be fuses and a DC-DC and at least 2 contractors.
There is much more.
You will be honestly better off just getting a Leaf and gutting it to make it light weight. I plan to make a little more torque then OEM with this but extend it to higher RPM.
This is not an easy task and many who try will catch shit on fire etc.
But let me work out the bugs before getting to far ahead of our selves.

Ach du heilige Scheiße! You probably blew at least 3 times as much in the process (blown up and dead ends).
Some EV company should hire this guy!
Huge regard to the work you did and are still doing for the community!

I am so deeply thankful for what you've kindly shared here my friend.
You saved the DIY community many of those 20,000hrs and hundreds of thousands of dollars in development costs.
I don't know how many years forward you shifted the EV revolutions progress, but billions of living beings will breath easier and skip cancer and genetic defect experiences due to your compassionate teaching efforts here. Thank you!

Yes You personally saved me 1000s of $ and 1000s of hours if not more. Thanks you High Hopes.
Anyone know what happened to 7c he helped a fair bit as well.....
I want to build lots of fun stuff and building controllers is the hardest part but its so fun to take on as a challenge not many have the patience for this!
Also need to help the others from earlier on like Bigmoose and a few others. Thank you everyone. I Feel I have crested a hill and now I can "run with it"
