Re: LS600H compatibility with GS450H
:grabs popcorn: Good to know that this is going somewhere after all :) Mine's still gathering dust. I'd opened it up and rewired it internally to the gs450h standard. And yes, a stock gs450h recognizes it and the readings via techstream are sane, the packet format ought to be the same. May I ask wha...

Re: Separating L110 transmission from 2GR-FSE engine (Lexus GS450h) [SOLVED]
Very offtopic - may I ask about the condition of the flywheel? It is a known (yet rare/obscure) failure point on the ls600h and the gs450h uses the same part.

Re: 450h Oil Pump Sounds Loud
Have you filled it properly? The fill procedure requires the engine to be running - this is done with the car in "maintenance mode", which makes the engine "idle" at 1000RPM, which drives the primary oil pump (the electric one is auxiliary - runs primarily when the engine is off ...

Re: 450h Oil Pump Sounds Loud
Doesn't sound like it's "chirping", I'd wager on the pump running dry.

Re: GS450h compatible transmissions and inverters
Anything that's put in a 3rd gen gs450h or a crown hybrid (GWS204 which is basically the 3rd gen 450h) should share the same control protocols. Transmissions-wise, as far as I know there are no differences.

Re: Lexus GS450H VCU Support Thread
My logs show ~167kW at ~1850 output shaft RPM in high gear with the pack sagged down to 335V. Pure math puts that at 860Nm at the output shaft. High gear is about 1.5x the output torque (1300Nm) but will top out at about 2500 output shaft rpm due to MG2 speed. Max motor speed is 10,200rpm for MG2 E...

Pretty sure that you won't be able to control this inverter with the gs450h VCU using the, ehh... "stock" code.

Re: GS450H - How to remove the engine - Any tips?
IS350 is the same way. Potential issues later on if you intend to reuse the cruise control radar - you'll have to recalibrate it, and that requires a special environment. (I assume that you did remove the radiator, rad support, front crash bar and all that - the engine looks like a somewhat tight fi...

Re: Project AKU: GS450h driven by GS450h transmission and GS450h inverter
Are you sure that the engine is going to be scrap money? I don't see many (if any) 2GR-FSEs left in the EU, and they are a somewhat hot item in some destinations (say, Russia - the 5th cylinder wear problems due to dust ingress past the air filter thing).
Anyways, I wouldn't scrap it.

Re: anybody work on the LS600h inverter?
The casing is pretty much the same, the IPM (igbt module) and control board(s) have the same physical dimensions and will bolt right in - no clue whether the wiring from the external socket to the on-PCB sockets is the same but it very well could be. The camry modules do have less IGBTs though - che...

Re: Not everyone loves BMW [SOLVED]
This is mostly about BMW's engines, I guess... and that's a trend with pretty much all European manufacturers. Chassis-wise, I don't really like macpherson struts on any higher-spec car for very obvious reasons, but... can't really fault what they've achieved despite them.

Re: anybody work on the LS600h inverter?
Just a heads-up for anybody that might be waiting on this, I've been, ehh... busy with other projects and the weather hasn't been too great outside... and now that I cleaned up the garage somewhat, an mr2 aw11 ended up in it..
I estimate it'll be at least a month more until I come back to this.

Re: anybody work on the LS600h inverter?
Great, I was worried that it had something to do with engine RPM control. Still wondering why the inverter has a camshaft input sensor... other than to compare it to the value that the HV ECU is sending and set a DTC if it differs.

Re: anybody work on the LS600h inverter?
gs450h HV ECU. There are DTCs for Engine and HV ECU mismatch in the manual, plus the ls600h's engine has a different powerband and is resp. kept at different revs, so I'm guessing that an ls600h HV ECU won't work - this assumes that the ECU takes care of orchestrating the CVT aspects. Plans are as I...

I know that there's no (official :D ) way to get data from the serial lines externally, I thought that the "snapshot" feature was a time-limited (well, memory-limited) internal recording mode of the ECUs that can be communicated with - engine, HV, abs/vsc/trac, etc - basically internal log...

The combined system power is limited to the engine's max power + whatever extra the battery can provide via MG2. http://eahart.com/prius/psd/ Same system. The inverter pretty much acts like an AC-AC converter, of the AC-DC-AC type. Engine rotates the fork in the planetary gear (think "planetary...
