: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...

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.

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 ...

Doesn't sound like it's "chirping", I'd wager on the pump running dry.

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.

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...

Have I missed some recent developments?

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

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...

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.

Haven't done anything, but the weather's finally getting decent enough to work outside. Might have something within a month.

You're limited by the boost converter's power rating.

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...

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.

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.

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: different HV ECUs talking with different engine ECUs - not sure ...

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...

I guess this is the better place to post this (i.e. not the gs450h inverter temperature thread thingy). At any rate, first try was a failure. The inverter fits somewhat. Following notes are for LHD cars: I used my old blown inverter's water inlet/outlet pipes (they're pressed into the main casting -...

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...

Opened the inverter in order to repin the 40pin connector, as the wire harness-side connector is, well... let's say that I uhh "broke" it without really breaking it, and I gained a glimpse of the insides :D . You have to insert your "SST" in the depin hole and push "downward...

Arrived today (well, yesterday), still haven't gotten around to wire it up. I think I'll end up rearranging the terminals on the stock wire harness, hopefully without breaking the harness-side inverter connector housing, as it's unobtainium, as others here have found out. Then it's a matter of conne...

Just as a heads-up, I finally ordered an ls600h inverter, should be able to provide info in... 2-3 weeks, hopefully. Sorry for the delay, other things took precedence :) A bit about the part numbers - g9200-500(11/21) - resp. (lhd/rhd) don't show up on toyodiy or the EPC app, I assume they're a very...
