It is very likely that you are hitting a discharge power limit.

no batt volts doesn't drop much and I've set any batt min limits 50v below that

I've sent you a bin with a change from Tom, possibly fixing this limit issue. God Speed

Thanks Jamie, Andy please keep to a conservatie throttle max for now, we want to see if the IDC levels off as quick now. Should theoretically not be the case so the torque will carry on for longer.

Too late bloody awesome
After these 2 runs I floored it and span the wheels half way up the road, my neighbours are so pissed most of the juddering has gone I feel a lot of what's left may be the backlash in my diff I'm not sure it will last much longer with that torque

Now thats more then double the current draw, and no flat point insight on the current draw. Better get the car ready for some higher speed acceleration tests.

I'm trying to find a new diff right now
You and Jamie are a pair of absolute legends

We. Need. Video.

what of me screeming like a girl wheel spinning up the road

sounds perfect, that was only 30% throttle too?

In all seriousness I really need to change the diff before it disintegrates, it sounds bad

the damn thing just took of like a bat out of hell I can't wait to do some real testing that was a real shove in the back

Be great if you could get the car sorted now you know she is dangerous. Then you can do on the move acceleration tests as those are more interesting from a performance point of view.

Give it a send off with a bang?

That would be foolish as I'd have to get it home from wherever it decided to die I'll leave that sort of thing to someone silly enough to get trapped under his own bonnet do you know anyone like that ?

I'm not sure that I do

having major hassle trying to get a diff with a better ratio, current is 3.45 best straight swap I can get is a 3.38 not a massive improvment but I want to get on as my mot is due in 6 weeks so I'm probably going to do it anyway

The internet says that the diff is the same as in the E36 compact, which should be available (somewhat) plentiful. At least compared to Z3 differentials.

The compact had 3.07 and 3.23 in the 323ti and 323tiA (which stands for Automatic I guess?): http://www.e36racing.de/differenzial.php

they both used the med case 188 diff

Many thanks Guys for all this info. Is so good to see this active experiment in action. These Transmission seem to have lots of potential, on paper before, but this is realizm. Well done..
Am still seeking a 300H inverter, as my attempts with the Prius zvw30 inverter could be needing this solution..

My new diff is on it's way so should be able to get on soon still have to sort out the bms and charging but the weather isn't being very cooperative but I'm hoping to have all of those working and the diff in by the end of the week

now my diff is on the way I'm really tempted to order a lsd for it in fact I'm on the Matt Lewis racing site with it in the basket right now trying to be sensible and really struggling because I really really want it

wow just realised this swap from leaf to lexus has taken 5 months so far, where did that go ?

Time flies like an arrow, Fruit flies like a banana.

You are making good progress, well done .

New Diff has arrived and I havent even unboxed it yet as wouldn't you know it, it's pissing down outside
