LEAF Performance tuning

What is the A-hr rating of your cells?

Maximum current limit for the cells may be holding back the inverter?

i don't think so as im still just getting the same power out put as if I'm still running the 110kw inverter.

Thanks for testing @xboxice , you are the first person so far to try this inverter upgrade on a 2018+

Time to order a CAN-bridge, I have updated the wiki with your findings!

You changed the inverter, but have the same cells.

The power to the motor is limited to the maximum current that the cells can provide (300A, ~3C ?), not by the inverter.

This is false, we have seen the 24kWh pack work great with a 160kW inverter, pushing out 145kW.

Oh cool ill check

Performance community, we need e+ CAN-logs! Currently all 160kW inverter swaps are limited to 400A, which means around 145kW max to the wheels. The e+ LEAF actually can do 180kW, but we haven't figured out what messages is needs to do so. If you have access to an e+ >2019 LEAF, and have the hardware to do a CAN-log of the EV-CAN bus (possible warranty void!), let me know. We need a full throttle run with Leafspy showing that 500A (180kW) was pulled from the battery, while CAN-logging.

Please don't PM me and say that you have an e+ and OBD2 dongle, this is unfortunately a bit more complex than that. We need someone willing to splice into the wiring harness to access the hidden EV-CAN on the e+. You will also need some dedicated CAN hardware to read it (Kvaser, PCAN, etc.) Recently I got a hold of the ZE1 workshop manuals, so here is the place where the ZE1 LEAF has the EV-CAN:

CAN-Layout, EV-CAN marked in red

One place to splice in would be directly at the VCM, connector E61:

The person that supplies the CAN-logs will have the most impact on the performance upgrade community by far! Can we make this a community effort?

Well if i can get that E+ VCM and if it works then i can splice into wires, just need instructions on how to do logs i bought the tools already

E+ VCM on its way I'm hoping the connections are the same on my wiring harness can anyone confirm the connections for E+ ZE1 and normal 40kwh ZE1 VCM connections are the same

I'm wondering if the E+ VCM will complain about 40kwh battery I.D when i install it? What you think.

[xboxice]

I can say with confidence the E+ VCM don’t work with my Leaf and I’m not able to clear these codes,put original back in and all working like normal VCM with the dots is the E+ and it’s labeled XE

Chipping in here...
40kWh 110kW 2019 leaf owner...
Super impresed at the changes you've made Dala, and loving the youtube videos..

I'm also wondering if anyone has simply swapped out a 110kW inverter for the 160kW one??
I think the leap from 150 to 215 BHP would be REALLY fun..

I wonder if it's as involving as what has gone on here at all?

Cheers

Hi Yes i have done it super easy to do only thing needed is Can bridge and Dala firmware to unlock full power from the 160 inverter
