Nissan Leaf Gen1 - Performance Chip Tuning

Wed Apr 14, 2021 3:51 am

I have finished a new software mod for Nissan Leaf Gen1 (24, 30kWh). It delivers One Pedal Drive in mode D, astonishing 40+kW regen till full stop, 90kW (122 hp) power and 300 Nm (+30Nm more torque).
Feel like owning a new Nissan Leaf Gen2, with improved regen even in cold winter, till the full stop.
Former 0-100 (0-60mph) is changed from 10.9 sec to 9.0.
In D-mode you can press the brake and acceleration pedal together. Now, while the brake released, the launch control mode is activated, delivering 300Nm of torque from standing still.
V-max is increased and set to 165km/h.
B - mode works exactly as before. If car has no B-mode - then it always runs in D mode, or ECO button can be used as a switch.

Now installed into our two Leafs Gen1, quite funny to drive with accelerator pedal only.

Soon Gen2 will be ready with some power boost and even better regen.

Question, how did you achieve more motor output? I have a hard time seeing how this could be done, since the inverter firmware is clamping down on any NM demand that goes over the maximum that the inverter is capable of.

For example, see this screenshot.
Image

This is a AZE0 24kWh that maxes out at 250NM. Even when requesting more than 250NM (with CAN-bridge), the inverter will not output more power. So you claim to be able to do this? EVs Enhanced, Muxsan, me, all have failed at getting more power out of the inverter. More regen is easy, but power?

This is what I got from an engineer over at EVs Enhanced:
Regarding the inverter stuff, I've already tried what you are talking about. The only difference is I did it through remapping the VCM rather than intercepting and modifying the CAN messages. Unfortunately despite requesting more torque, the inverter did not give it. Just to rule everything else out, I wanted to test the theory that the inverter was clamping the torque so we bought one of the aftermarket Thunderstruck inverter controllers. We made up a separate loom so we could unplug the stock Leaf wiring to the inverter and run the stand-alone controller. We then ran the car up on the dyno while gradually asking for more and more torque. It turns out that no matter what we did we could not get any more torque or power anyway over stock. The best torque curve was identical to stock. We could easily ask for less torque which would work fine. Asking for more torque than stock did not make the inverter shut down - it just would clamp the torque to the maximum allowed for that motor speed.

Call me interested! Not so much for the power, the stock power is more than enough for me but I am interested in the greater regen, especially in the cold and does it still work when the battery is degraded, to say 8 bars? Currently my '12 8 bar Leaf has very very little regen, basically at any SOC, maybe 2 bubbles max and in the cold it has 0 regen available :( My 11 bar '13 is quite a bit better, gaining regen when down to say 95% SOC and by 90% is almost all bubbles but it still suffers in the cold where I'm only able to get 2 maybe 3 bubbles max.
I'm also a little worried what all this extra regen might do to the battery, I assume Nissan limited regen for a reason? I guess especially on the '12 I'm not so worried about shortening the life of the battery as it's so degraded now but I wouldn't want anything to blow-up by getting too hot, is all this regen safe?
I should also say, while my '12SL has a QC due to the battery being degraded? when temps are in single digits I'm lucky to get 10kw/h even when using the QC, hardly faster than my '13 on L2 where I get about 6kw/h.
Again I'm interested, is this a DIY, if so where would I order it and how much :)

Yeah, I noticed that regen was limited to the max that DC fast charge would do at the same SOC, that can't be a coincidence right? :?

Actually, I believe regen is limited to 25 kW or thereabouts. Given the fact that the LEAF will DC fast charge at a sustained rate of 40 kW for much of the charging curve in mild temperatures, it seems like pushing regen to 40 kW shouldn't cause any damage.

I love that idea of stronger regen. Out here one could fast charge their battery going down certain mountain roads.

On my 2013, provided the battery was warm enough, I've seen 30 kW in LeafSpy. It would be great to bump it up to 40 kW, but I still think it will depend on the temperature of the battery, so in the winter, I wouldn't expect to see the 40 kW boost unless the battery was warmed up without being in a high SOC.

Don't know how accurate the energy screen is on my 2012 - it pegs out at 30 kW regen even with 100% charge (or at least a few miles on it) with purposeful braking pressure. This is with 5-6 temp bars and my ~ 50 amp-hour "Lizard" battery.
