Curious what you guys are spending on bypass modules, ecus, and harnesses when you could probably just go stand alone ecu...

If you know where we could buy a stand alone reasonably to run a 2uz please share.
I purchased a oem ECU that came out of South Africa for 750.00 US after shipping.
I purchased the Bypass module out of Russia for 125.00 after Shipping.
There was a company in Australia that said they could build me a bypass module but it would cost about 2400, not sure if that was AU or US as I did not follow through.
I saw in a thread I found on IH8mud that there may be a company in South Africa that could build a stand alone harness and ecu but could not find enough information to locate that company. I read so many threads researching that I cannot recall where I came up with this info.

Pondered these topics over and over in my head. Stand alone would work, but I’ve never driven a stand alone anything that works better than the factory version....if your going for modified this and that then it’s a different conversation. They always have quirks and have questionable reliability. I was going to do this at first, but lost interest due to expense vs end result....I’m content with a stock 2uz, therefore no go for me.
I have intended to “bypass” a stock ecu for a while now, I have serious intentions of building a 2uz/h55f combo for a 60. Although I considered the bellhousing to be the hard part, if we can get a supply of bellhousings that are good for quality, manipulating the factory electronics will be very doable. Building a new harness for conversion purposes, if only I had someone paying me to do it.....right now it’s just a dream...
The 2UZFE stock ECU runs the engine without the auto slush box attached. It will store codes due to missing signals from the transmission, but the engine still runs properly.
It has been a while since I buried my head in this, but if I recall what it won't do is start if it doesn't get the appropriate signal to indicate that the transmission is in park or neutral. The ECU also limits max rpm (to 4000 rpm IIRC) if it is running with the "missing transmission" in neutral or park.
This shouldn't require rocket science, piggyback ECUs or other gadgets to overcome, you should just have to supply the ECU with the appropriate 12v signal for "park/neutral" and "drive" positions etc.
From what I remember there were added complexities with the later 2UZFE VVTi (2007 and up - again IIRC), because of the VVTi, and its electronic chip key. The ECU needs the signal from that key otherwise the ECU won't allow the engine to crank. I don't remember what the complexity was with the VVTi specifically, perhaps there wasn't one, or maybe it was just the immobilizer key/ECU combo, but reading about other 2UZFE swaps I seem to think it made life more difficult.
I made sure that I got the ECU, harness, throttle cable and all bits and pieces I wanted from the guy who was parting out the donor truck.
There have been quite a few 2UZFE swaps done, most using the automatic, but plenty without. These guys are doing 1UZ/2UZ swaps in manual transmission 4Runners and other Toyotas. They have on the shelf parts to do these conversions, motor mounts, transmission adapter plates etc. but nothing specific to Cruisers unfortunately...

Any generic standalone that has variations in its setup will run a 2uz. Might need a few minor modifications (like a crank trigger wheel) or what's there might be usable.
Generally the 'reliability' factor from standalone come from one of 2 places....
1 is just improper setup/tuning
2 is from a bitter taste OLD megasquirt systems left in peoples mouth
While I agree the 87 MR2 with a JDM supercharged engine (factory was a coilpack non vvt version -though there are success stories of vvt 20v's on MS.. and its come a LONG way) on Megasquirt 1 v2.2 had some reliability issues.... it ran the engine with more power over a stock SC mr2 (which had a rebuilt engine, 10psi pulley) it also allowed me to shut off the SC and get 50mpg. It was far superior to the stock ecu aa it wasn't built conservatively for the masses.
I wouldn't be surprised if there's a shop that KNOWS megasquirt couldn't install, wire, and tune one for under $1500....
If you do something like that then you can do some pretty cool stuff...

@Rusty, It looks Iike your knowledge and wiring abilities are far better than mine. I need something that is largely plug and play. I can switch pinouts and splice things together but beyond that I would have some learning to do.
I had reached out to North West Toys some time ago and from what I remember they were not able to do it. I just sent them an email inquiry to see if they could build a harness if I supplied the parts. I will post up what here back. It would be awesome if they could. Thanks for the suggestion.

Well that's a guesstimate if a shop completes all work and puts some dyno time into it and uses q nicer/newer MS than I've ever used.
I was under $1k in the fj40 (350) with the MS1 V3, upgraded to MS2, ignition and fuel components (including pump, AN lines, etc), the wideband O2, the full software suite of tunerstudio, and the custom rpi with 7" screen running said tunerstudio for real time monitoring, logging, and tuning...
I wasn't attempting to trivialize what you've been saying. No matter what there will be a fair bit of figuring out to do regardless of the route you take. I had also considered an aftermarket ECU but at the time there wasn't anything plug and play, lots of suggestions as to what ECU to go with but not much else.
The more I looked into it to me it seemed that going with an aftermarket ECU was much further from plug and play than using the OEM ECU and wiring harness. Sure you do have to figure out what you do and don't need, what to cut out of the harness to tidy it up and what to keep, and which signals the ECU logic needs to meet permissive so that it will start, run etc. Toyota V8's aren't exactly the ubiquitous choice for engine swaps in North America, finding someone to build a harness and tuning an aftermarket ECU from scratch will be difficult.
Don't know if you've come across these guys before, they're also in Australia, you might want to reach out to them...

I found that I had two options, find a tuner who is prepared to take on the project, drop it off at their shop and start shelling out the cash or buy the OEM parts, the Toyota Tundra factory wiring manual and start cruising through schematics to figure out what the ECU needs to be fooled into working without the transmission - sticking with the Mr.T tune.
The factory Toyota wiring manual that I bought for my year of Tundra motor is really good (found it on Ebay fairly cheap). I managed to discuss what had to be done with enough people on various forums (Lextreme etc.) who had used the 1UZ/2UZ engines and stock ECUs for their swaps. Although it's been a while since I've thought about this I would say that if you are comfortable with splicing wires and switching pinouts I think you're more than half way there.

I had a recent email conversation with Northwest Toys. They now have an adapter. They quoted me $1400 for the adapter and $700 for a clutch kit.

I have reached out to them by email twice and they never responded. I am glad you got some information.
Curious what their adapter looks like. I looked on their site but cannot find any reference to it. Are they only doing these as custom orders or are they stocking these parts? Thanks for sharing.
When I spoke to them on the phone awhile ago they quoted me around the same total price and their supplier was Dellow out of AUS (they did not stock the parts). Did they say their adapter is now made in the states?
No, they just said they had an adapter. I did not ask if it was the Dellow part.
Bump....
LAND CRUISER 60 SERIES WITH V8 LEXUS 1UZ 2UZ - BELLHOUSING - Dellow Conversions
New Dellow conversion bellhousing fits the Lexus 1UZ-FE or 2UZ-FE V8 to the 60 Series Land Cruiser transmission replacing the factory engine.

Back to this, as I dream of Roscoe’s next level. Anyone still think this could be viable and reliable option? or is price really the main barrier...!? I would need a shop to do this for me... just looking at options

@cruiserjunktion is in the process of pulling this off with a combination of cool parts, although 1uz? Right Deo?
unfortunatley Dellow has been an unreliable source for US customers....hopefully the market will provide manual conversion options soon.....if I don’t jump on it myself!

Good luck getting anything from Dellow. I inquired and got some email responses but could never get them to sell me an actual part, they seemed to busy to care about dealing with shipping anything to the US.
If you do get somewhere and want to talk details on a project let me know. We do a lot of Cummins and LS stuff but I'm looking at a 2UZ swap for another potential customer (auto though) and would like to do more with them.
Doug have you tried to reach out to NWToys?
Domestic and from what I understand they have way more parts/services available over the phone than via website.

No, since I abandoned the 2UZ idea and decided to go turbo 1FZ for my Goat build I haven't really worked on the project. The potential customer I mentioned would stay automatic so the bellhousing issue doesn't apply to him. I've heard of NWToys but never called them.
