Sorry late to the part on this one. My trans is bolted straight to my frame using angle iron with 1/8" rubber pad where the iron matches to the frame. Not elegant, but it's lasted over a year: viewtopic.php?p=32724#p32724

Feel free to look at my MG Midget project thread. I pull 250-300 amps at full throttle on a pretty small car. Running at 45mph, I'll range 60-80 amps. My pack is 320 volts fully charged.

Quick update: thanks for the [TAG] idea. Love it. I've been using this car as a kid shuttle around the neighborhood for well over a year now. Batteries are holding up, no huge issues. My MG1/2 configuration is pretty flawless (no locked input shaft, spin up MG1 for oil pressure. See earlier posts). ...

I am happy to help. No issues with the questions in this thread.

Yes, you wire directly into the inverter with whatever volts you have without using the boost side of the inverter.

Nice project! You're not going to hit 14K because of the 10K limit, if I recall correctly. Why do you need 14K rpm? My rear end is 3.99 and I can get to 60 w/o taxing the RPMs. Just curious. Also, remember the inverter makes all the volts as needed. So, even if you're only running 288v, the inverter...

sounds cool! you'll have plenty of room for that battery pack. what's the vehicle/weight?

Large van? Well.... I have a 24kwh battery, of which 15-18 is usable (I don't drain it and I don't charge it completely). I can get an honest 80 miles with those 15kwh in a car that weighs maybe 1700 pounds, and that's only in-town driving with mild regen. At a constant 60mph, my car pulls 60-80 amp...

MG2 I believe has a max of 10K RPM for safety reasons. And you can get there with very few volts as long as it's not hooked up to anything. I can spin MG2 over 2000 rpm at 30v/10a (300w). It's not the voltage that drives power/rotation under load, it's the watts. Unloaded, you can push MG2 to it's m...

Rereading your post - no, locked MG1 cannot provide oil pressure at a full stop because it's locked to the rotation of MG2. When input is not locked, it can freewheel, able to provide oil pressure at stop when applying torque to it. When input is locked, MG1 and 2 work together to power output shaft...

It's working very well. The input is not locked in my application. If it were, I would not be able to make oil pressure without the external pump. Since the input is not locked, I spin up MG1 to make oil pressure, and then once MG2 is above a set RPM, then I shut down mg1. Underway, oil pressure is ...

NEW PICS --

Rust-o-leum paint job complete. Officially 2 full years since I started work on the car.

Can I ask, does the regen work with your inverter and VCU board. If so, how does the GS inverter know what voltage to use to charge your battery? Do you have the program the VCU with your specific battery data or does the inverter just magically know? Regen works great. But, I did not change anythi...

I don't use the electric pump at all. See my previous post on this topic: https://openinverter.org/forum/viewtopic.php?p=39923#p39923 Works like a charm. Really great information and researching so far, thanks to all contributors thus far!! Has anyone got any further with this "shifting on the ...

I don't use the electric pump at all. See my previous post on this topic: viewtopic.php?p=39923#p39923

Works like a charm.

I thought about the electric clutch thing, too, but my car is so small, I decided to not use MG1 at all.

Here you go ..

Hey Dan - I've got my 450h wedged in a 1979 MG Midget. Of course, half of it is in the engine bay... Haha. There are posts about dimensions in the GS450h discussion thread (one of the busier threads in the Toyota/Lexus section). Let me know if I can help. My build is super simple. Check it out in th...

I posted a GS450h input shaft spline in a separate posting in Classifieds if interested.

Hello -- I decided not to lock the input shaft on my GS450h project and am willing to sell the flywheel / damper / spline that I bought. Will not be using it. I liked the idea of having the damper because it would have buffered some vibrations when on/off throttle. DM me with an offer. This thing is...

A quick update. Dash is back in with new gauges and all lights working. Turn signals, headlights, hazards, parking, license plate, etc. all good to go. Next steps is center console and some relays to force driver to put system in Park and depress brake to place in Drive. Reverse will be called up by...

I've had zero problems with the user version of the firmware. What are you experiencing? It' definitely primitive, but I wouldn't say buggy either. The only bug I found while rewriting it was this buffer overflow vulnerability: https://github.com/damienmaguire/Lexus-GS450H-Inverter-Controller/blob/...

I've had zero problems with the user version of the firmware. What are you experiencing?

I run mine at 30 PWM (that's the setting I give the VCU -- does that mean 30PWM or 30% of 100?) and can drive around just fine on that. What firmware are you running? I'll double check what your 30 means :) https://github.com/damienmaguire/Lexus-GS450H-Inverter-Controller/tree/master/Software/gs450...

I mean, I've been driving the car around just fine with no oil pump or solenoids connected. But OK. Do you mean you're not pumping oil at all (input shaft locked, and no electric pump)? Or are you pumping oil some other way? I assumed it was essential to have some oil flow! I need to look into how ...
