Next up I will deep dive into the new harness, show you guys the wiring, the tuning, what sensors are required, everything I can! The truck was rushed out of shop to make room for Max! It was done just enough to move it, nowhere near complete.
I know it's a little late, but you were complaining about your idle being different every time you start the engine. Thats probably because of how it was wired up. On the original 1uz wiring harness, the IAC valve (and a few other components) is powered by the main relay circuit. On your truck, the main relay is controlled by the ignition switch, but on the Lexus, the ECU had control of it through the MREL output from the ECU. The ECU would keep the main relay on for a few seconds after the engine was turned off to reset the IAC valve to a starting position. You probably did not Wire that properly, so your IAC would be left in a random position every time you turned off your engine.(Your IAC valve could also be sticky... you could try servicing it.) There is no way to plug and play the 1uz and have it properly wired, in a pickup/4runner of that generation. You have to make some small adjustments to the stock chassis wiring for it to be correct. 1) disconnect the ignition switch from the main relay wire and connect the ignition switch to the ignition power terminal on the ecu, 2) connect the MREL terminal on the ECU to the main relay to activate it. 3) wire the Circuit Opening Relay through a safety device. (Unrelated to the idle problem... this is for safety. This is usually hard wired on 1uz swaps, which poses significant risk in the event of a crash. This circuit is supposed to shut off the fuel pump if the engine stalls. This prevents fule being pumped out of the tank if the fule line is severed after a crash. Normally this is controlled by a switch in the Vane Airflow Meter, which, of course, the 1uz doesn't have. At very least, this should be wired through an inertia switch. Better yet, a module that looks for tach or ignition signals and turns off the COR when the signal stops.)
Excellent vid, highly informative even for a numpty like me ... I have a Soarer V8 (UZZ31) and the idea of swapping to a standalone ECU appeals to me as I've already ahd to replace one ECO due to caps leaking ... many thx for all the extra info on this vid ... top work
Very informative and to the point videos! Couldn't find the info on the bell housing/adapter for the r150 to uz engines you used. I've swapped a 1kz diesel in my truck but looking to do a v8 in my 4runner.
Got a 81 Corolla wagon what do i need to make the complete swap. Will I need the cluster from the ls400 and what about the rear diff would I have to use the one from the lex?
Do you have links to all the items you used? I have a 92 1UZ with a MAU-5 Trans I'm making am adapter plate for. Wondering if I should get the kit but trying to budget. How much did the R8 coils run you
@@DirtGarage I thought so. Is this from the seller out of South Africa? I’ve been very tempted to go with that kit but I wanted to see an example first.
Your idle control was functioning correctly. You wired the swap wrong. In factory form the idle control stays on after shutdown and moves in a full sweep so it can reset and be in the correct position for the next startup. Your must have been off on shutdown making the next startup wherever it picked up from.
DG, I plan on buying a 96 LS400 tomorrow. I take it that this kit will work on it? Or is there a different kit for an automatic transmission? I'll do some more research as well.
@@avianaviator1570 2004 and I had to sand the ridges off the tubes. There are also two ways of making them long enough to reach the spark plugs fully. One is to mill the top lip off the valve cover, which is what I did with a grinder or to use vw cool boots on the ends. They also fit under the covers fully both ways.
@@avianaviator1570 But if you are doing this I have since found out that 2003 Toyota 3rz coils work better. I have also heard that the 2uz coils work as well.
Very nice. I also use Spitronics ecu on my 1uz, Saturn Advanced. Great power and good fuel consumption. Not sure if your ecu is wired through the narrow band sensor. Mine was wired through a wideband afr gauge, using the analog output. Can not remember what value I put in for target afrs and lambda control but it makes it sip fuel and you can monitor your afr values while driving. Also adjusting the maps makes it a breeze. I wired in an intake air temp sender to pull timing on hotter days. As Spitronics does not have a knock sensor, the iat sensor pulls a bit of timing on hotter days to avaid pinging. I run the old dizzy cap setup. Also going to do a CoilOnPlug conversion in the future. It was my understanding 1 of the cam position sensors was needed. Good luck and keep it up

💪🏼💪🏼 cant wait! thanks!
That is actually one of my custom Spitronics ECU / loom kits. Awesome to see it halfway around the world going into a car.
I'm looking @ your service also :)_
any chance I can get one!
@@boisebiker4713 yes there on eBay
Where can I buy the wires and the computer much they sell.
Hi Louis , how’s the customer support for Spitronic?
Any new model out or full loom kits available? Heard good things about it .
Fuel injectors status will always be a notable 🤙
Great mod! This opens up a lot of potential 😈
Yes sir!
@@DirtGaragedo you have any link to buy this ecu & harness?
Max is there?! Watch out, he may have another "Maxident"!
I love your build! Keep it up :)
What year Audi R8 coil packs are those
Could I run the whole truck and coil pack conversion off the standalone ECU and keep all my factory gauges, body harness and OEM a340 trans?
Do you have a link to the spitronic harness and cop you used
This is gonna sound kinda dumb it I’m gonna ask anyway, is there a way to switch to hydraulic lifters for the engine?

The stand alone clears a lot of space under that hood. Nice job.
So much room! It's really nice.
@@DirtGaragehow do you wired for oil pressure gauge? Im still kinda confused

Excited to see how this works out just got my ecu back from Relentless Motorsport a few months back and seam to be very happy.
Hey can you send me a tune you have on the truck ? Please
Amazing, i am wanting to do the 1uz swap into ny 92 landcruiser. What did you do for Speedo drive? Is it possible to still use the original dash?
My whole dash is functioning just like stock. And speedo still uses stock cable. Stock transmission and my transfer cases are same as before the V8
Bro can you sell me those routes
Just watched BuildsNotProjects do this on his pickup a couple weeks ago. I'll be interested to hear your long term take on this mod.
Haha we where talking about stand alones for past year. He went that route first, and I got it based off his feedback.
Gud machine I like it

Got 1 for you
@@SrIrv still have that adapter?
Got a 81 Corolla wagon what do i need to make the complete swap. Will I need the cluster from the ls400 and what about the rear diff would I have to use the one from the lex?
I got a question, can a 36-2 crank wheel from a VVTi engine be used on a non-VVTi engine so I can run batch?
Is there a good reason why you went Audi r8 coils and not others? About to do this and your advice is much appreciated!!
What about putting a 1uz in a first gen tundra.
Do you have links to all the items you used? I have a 92 1UZ with a MAU-5 Trans I'm making am adapter plate for. Wondering if I should get the kit but trying to budget. How much did the R8 coils run you
R8 coils where like $16 each on rock auto. I don't have anything linked though, it's a ebay listing and those always change
What about the Sprocket, was that also part of the kit?@@DirtGarage
I see now, dumb question lol@@DirtGarage
Part number for the ecu please
My ecu is not supplying power to coils....please help
I need some more instructions for the starter harness u made 😅 idk what u do but I need to the same thing
Any chance on getting a video or a link on howl to build the remaining part
Of the harness needed.
co$t for harness and ECU
Will go over in next video!
Spitronics the way to go 👌greetings from Mosselbay
Could this have E throttle? and are the ignitors on the coils or built into the ECU?
Can u provide link to coils I’m doing exact same setul
Nicely done! Should see some real power gains from this. One day I will go full standalone on my 1uz pickup. Where did you source your setup from?
eBay, If you look up 1UZ stand alone there you will find the same kit.
@@DirtGarage I thought so. Is this from the seller out of South Africa? I’ve been very tempted to go with that kit but I wanted to see an example first.
@@Jay351 Yeah it's from South Africa

This does not work for auto
Are the igniters no longer required with this swap?
They get deleted. And coil packs. It's all built into the COP
@@DirtGarage Thanks for the response, I am going to be doing this swap into my Supra and your videos are amazing!
Did someone say Land Cruiser??
I ran megasquirt on both of the ones I did. One stock ignition the other Prius coil on plug.
Do you remember what year Prius coils?

Updates on the Spitronic ecu
11 month later ?
Still fantastic 🤘
Hope that solves all your weird quirks.
Me too!
So horny for a v8 swap in my 99ltd 4Runner
Do it!
i’m doing a 1uz swap into a jeep xj would you recommend doing this mod before installing it?? i’m also doing a m90 supercharger
If you are installing a blower 100%, makes wiring a breeze too.
@@DirtGarage where would you recommend buying one of these
@@DirtGarage do you think i would need to get it tuned running small boost with a supercharger
Can you provide a link to Max channel.
th-cam.com/users/MaxxPowellOffRoad
What made you choose that specific standalone kit?
Price. And lots of 1UZs on TH-cam with it.
Land cruiser? 🤨🧐🧐
What did you do with the old harness?
It's around still.
Would you consider selling it? @@DirtGarage
👍👊
what's the exact ecu and harness that he use
Spitronics Mercury 2. It's a kit from eBay
How much was kit and coils ?
I'll go over this in next video!
I’ll buy your old harness
It's kinda thrashed.
@@DirtGarage did the spitronics come with a base map?
@@tyronejenkins855 Yup!
@@DirtGarage can you tell me where I can get it? I’m running a stock trans
And price
Is it user tuneable
Yup! I'll show this in next video.

The Mercury2 unit can run multi coil with only 36-1 crank trigger, no need for cam sensor.
@@SuperbugRacingRSA That explains it.
Never had a Mercury 2.
Thanx
Is there a ecu spitronics for 1uz vvti (Venus)?
The heart of a vw now
Atleast the pulse haha
