- A step by step process on tidying up a 1uz throttle body off a non-vvti engine so Gen 1 or Gen 2. This process can be used with both stock ECU and aftermarket ECU using both the stock idle air control (IAC) or an aftermarket unit. I also include two different ways of setting the throttle position sensor.
Mate, just wanna say, thanks for taking the time to share the knowledge and how-to's that you do. I wasn't feeling very confident going into my build but your channel is helping sooo much. Once i have a better idea of the direction im taking this build (turbo/supercharged) ill be in contact. Got a major rewiring job to do first due to last owner going rip, sht n bust on interior wiring.
Thanks for the compliment. Cheers Kelvin
Agreed. Mos blokes I approached are stingy with advice.
Hey Kelvin, thanks so much for all the super informative videos, fair play for sharing all this valuable info, a lot of lads would just keep it under their hat. I'm well jealous of your workshop view, it's super 😎 keep all the videos coming. Greetings from a damp Ireland,
Alex
Just followed this video to remove the traction control butterfly, from my 1UZ. Only running the standard ECU so haven’t deleted anything else yet. But looking forward to giving my engine a really good going over this coming month or so. Just ordered some of you diagrams today. Thanks heaps for these videos
Glad it helped
@@CartuneNZ can you run without the butterfly
@@juliioa.j207 yes, traction control butterfly can be removed fine
Man have your videos helped me! Between the ufc20 wiring, the coolant line delete, and this video I have been able to really simplify my swap. I did decide to put it in my mk3 supra instead of the mk2. It's a much less involved swap. Just got done cutting the TRAC parts off my throttle body and about to head to the hardware store for the right barb and tap. Just gonna thread a plug in the backside being I will be running stock ECU. I know I've said it before but thanks a million and I can't wait to see more!
Cool as. Glad to help.
Thanks for making these videos. Cheers from South Africa.
Cool as.
You're a badass Kelvin.Greetings from Poland
Thanks. Cheers Kelvin
Good stuff. This channel is a goldmine for 1uz knowledge. Quick question Kelvin, if doing this modification for a streetable build, how would one go about turning off the TCS lights on the dash? Besides deleting the bulb of course lol. Cheers
If you listen very carefully in some of my wiring videos I mention that the traction control and non traction control ecus are the same, with the difference in the harness. I know how to mode the harness to convert them to non traction control. If this isnt done then there will most likely be issues. The useless info I know.
Nice vid sir.
Hi Kelvin do you have a part number for the Bosch style air temp sensor. Regards Ian.
Witam!
Odkąd stałem się posiadaczem Lexusa LS 400 f1 często oglądam Twoje filmy. Szkoda że nie znam na tyle angielskiego.
Czy ktoś mogłby mi wyjaśnić , dlaczego warto przerabiać tak przepustnicę?
Domyślam się, że auto ma lepezą reakcję na dodawanie gazu.
Ale ręki bym nie położył 😁
hi Calvin I recently did a conversion on a toyota hiace , i have put a 1uz i am using the standard ecu how far does my air flow sensor be from the throttle body i am using the standard throttle body, or what 's your best advise
We normally run them between 200mm and 400mm from the TB without an issue. Cheers Kelvin
My first gen ucf10 starts and then stalls. Will run fine if I hold throttle on but won’t idle. I’m new to this platform but am I right to replace the IAC valve?
I have videos on repairing the isc which I'd recommend first. Cheers
Can you use a drive by wire throttle body on an early model motor ?
Sure can if you want to modify the plenum to suit the VVti throttle body as the flange is different and then run a suitable aftermarket ECU.
I've got a couple questions about this mod Kelvin.
Will I be able to retain cruise control with this mod?
Can i delete the coolant lines to the stock IAC?
Does the valve cover breather on the throttle body side need to be returned or can it be vented to atmosphere with the TB nipple blanked or ran to a catch can plumbed in along with the pcv? (I already have a full egr block off plate so the pcv doesn't get returned anymore)
Set up is currently not boosted but plans are in the future.
Thanks, Ian
Hello Ian
Yes cruise control can be retained.
Yes the coolant lines can be removed from the iac.
correct PCV removal is on my list of videos. So many people dont understand the system and get it wrong like yours doing more harm than good. While I prefer to keep the system in place and working as it aids in both engine running and power it can be removed if required. A catch can with vents to both tappet covers is best. Especially if boosted large lines into both tappet covers.
Cheers
Kelvin
@@CartuneNZ great thanks so much Kelvin
What setting do you have the voltage meter on?
Hi, do you use that iat sensor for factory ecu aswell? Or just blank off instead if keeping factory ecu
I only use that IAT with aftermarket systems. For stock ecu the hole is blanked with a frost plug and stock IAT in AFM is used. Cheers
@@CartuneNZ thanks for the help
@@joshcoleborn1129 Whats your 1uz in? Sounds like you are running stock ECU?
I have a 99 single cab hilux with a 3rz-fe that has a dead motor and been looking into a 1uz-fe swap, I've found your trademe auctions for conversion parts, would you have an email or something I could send some basic questions to you on before I dive into the swap (which type of motor to get and that sort of thing)
@@joshcoleborn1129 info@thecartunecompany.co.nz just understand im busy and wrote my conversion instructions because i get asked the same stuff all the time and it drives me nuts. Check out the auction on trade me. I also do a better deal on a few bits to customers that buy these. Cheers
Hey there, just subscribed.awesome channel. Where do you get the plugs for coolant ports? Any links or specific name or brands?
Good morning. For the plugs for the coolant ports the back one is the blank rubber from the front of the IAC (JDM spec, No EGR). The front coolant ports we alloy welded up although it would be simple to either lathe up some blanks or I have also tapped them and screwed in some grubscrews. Cheers
CartuneNZ may just be video quality, but it looks like you hammered some sort of metal plug on the top ports of throttle body closest to manifold
@@charley240sx there are two air fittings in the TB which were blanked with lathed up plugs. One was for the supply to the purge vsv and on the race car TB we blanked the engine breather. On the other one the engine breather was left alone. We just machined up some alloy plugs for these. The waterlines to the TB were sanded off completely just to make it look better. Cheers
Will my acceleration increase , or get better acceleration responce if i unplug the traction controle motor, and remove the traction controle cable?
Unless your traction control has a fault you should get zero difference in acceleration by unplugging the traction control motor.
My 97 ls400 stalls and dies only when hot, cold start fires up 1 shot,once it cools down it fires up and doesnt die again until i turn off ignition and try to start but stalls when hot again.
Changed knock and both cam sensors,cap and rotors,both ignition Coils and igniters,wires and plugs,fuel filter and fuel pump, ordered exact same ecu matching numbers but same problem, no obdii codes except cylinder 1 missfire....any clue?please and thank you.
Looks like some more advanced diagnoses is required. Does it start and stop when hot and then not start again until it cools down?
@@CartuneNZ yes sir
Only starts again when it cools
How much of this can be done to a factory soarer? I am hoping to tidy up the engine, including removing the traction control.
I can't see why all of this couldn't be done on a traction control soarer. The great thing with the soarer is it's straightforward to wire a traction ECU to become a non-traction ECU. Cheers
Hi Kelvin, just wondering if I need to run the coolant line to the factory IAC?
Thanks, Ian
Up to you. I remove them as per my video.
@@CartuneNZThanks, Kelvin. I just didn't know if they are needed for the IAC operation with an engine running the stock computer.
Cheers, Ian
I am getting code p0510 closed throttle position switch malfunction. Is the tps bad?
I would be starting by testing TPS and idle switch, and consider it may also be an earth issue or ECU fault. Testing is the best way forward. Cheers
Does it increase the engine speed with air conditioning? Or only when the engine is cold?
Is it available for sale? Thanks🌹
Hello. This is a throttle body mod. I made the video so guys can sort their TB out themselves but I do modify some at times for local customers. The idle speed is on the front of the plenum and if everything is wired correctly there can be an idle up for A/c and cold. That is contained in management
Traction control butterfly stays closed you were saying
Hello. Maybe I said something funny. Default setting for traction control butterfly is open. Cheers Kelvin.
@@CartuneNZ hahaha
Hello CartuneNZ,
I'm unable to calibrate my sub throttle position sensor on my 92 sc400 and I believe it may be due to the same issue as you described at time 1 min 55 sec (you mentioned the butterfly valve is shifted upwards and upon inspection, mine is also open half way at idle and closes by pushing/ pressing upwards). I believe this is the reason that the pins on the sub throttle position sensor are shifted and not aligned the same way as the throttle position sensor. I tried testing for continuity at the e2 and idl termials like you showed in this video but the sensor is positioned so far forward that it reads infinite resistance. Is there a way to reposition the butteryfly valve? Any advice would help and would gladly support your patreon page.
Best Regards,
Pawel
I would be removing the sensor to test on the bench. If the issue is the butterfly shaft then there is a major issue. I see it lots where the sensor is incorrectly fitted too.
What's the purpose of deleting that coolant line?
Makes the engine bay neater and the engine easier to work on.
@@CartuneNZ got it! next question: what grommet did you use on the air temp sensor?
I measure up my sensor and chose one from rubber shop. That reminds me I must get more of them.
Can eny thing be done to the vvti throttle body.
Not really, maybe they can be polished if you wanted. I prefer to leave the water lines on as the cooling system bleeder is on the TB on the 1uz VVti TB(thats the hex head blanker on top). I did have one recently which the water lines weren't connected but not my preference. 3uz VVti TB is pretty basic and the tidier of the units. There is nothing extra like traction control and no external IAC as thats sorted by the drive by wire so I leave both the 1uz VVti and 3uz VVti throttle bodies standard. Cheers
@@CartuneNZ thank you for your reply.i have a p1663 fault coming on I have fitted new vvti sensors on both sides and it's still there.
Check wiring.from wat I can see it's ok.you know eny thing I can check.
@@davidpritchard6685 Im guessing this might be in a conversion so its just been wired in? Or is it a factory vehicle? 20 series vvti, 170 series vvti or another?
or by the way I am Shaun from trinidad and Tobago
Nice to meet you Shaun. Cheers Kelvin
Do you need the dampener for the throttIe cIosing?
Hello Brendan. I prefer to keep the dampener on for every job I do. Ive had quite a few guys bring their vehicles in without them complaining of stalling , especially on stock ECU, and by refitting the dampener it solves the issue. Cheers
