Yes, that issue has been resolved with the update. Thanks for watching!

@@Carnold_YT How?

It operates in a set speed range, unlike the 13B in the RX models that is often redlined. So, that is better for the long term reliablity and I think this 8C engine can in fact last the lifetime of the car. But as with anything, time will tell.

That is right, I've made a follow up video to adress that oversight.

Hey! Well, the remote control still doesn't work Ryan, and the drivers door doesn't lock if I unlock the passenger door with the key. The rear doors unlock / lock just fine. So if you have any tips, that would be greatly appreciated!

You should check the metal actuator rods that push/pull the lever and make sure they are not bent. By looking at the lever when you press the lock/unlock button it moves just slightly as if it's trying to lock/unlock but if the geometry of those rods are not straight than it will bind and not move. It was like that with mine too. The rods can get bent when removing the door panel. Especially where the two rods connect on the pivot point seen at top of door @23:26) that turns when locking/unlocking. That's where mine got bent outwards when removing the door panel. Bent it back now all is good. Hope that helps!

It depends per car in my experience. This car had ignition and transmission issues due to the leaking caps, the fuel consumption wasn't bad (and not because the car was undriveable), 10 liters per 100 km's. For my own LS 400 (Project LS 400) the fuel consumption improved from 13 to 10 liters per 100 km's. Bad fuel consumption in first gen LS 400's is often caused by multiple things: O2 sensors going bad, injector wear and very often a cold start injector that is stuck open. Often times, these things occur at the same time. Back to your question: replacing the capacitors can indeed improve the fuel economy, but 10l/100 km (or 28.2 MPG UK) is the best I ever got out of a LS 400.

@@Carnold_YT Ok thanks for your advice. I have a 1993 SC 400 and it runs fine but its getting terrible fuel economy bad like a 75l tank will last me maybe 330km not sure what the issue is might do the spark plugs and see what happens. Might get someone to check the injectors or cold start injector that you mentioned.

@@nigel7598 That is a pretty high fuel consumption Nigel, I'd suggest you start with the cold start injector under the intake plenum and disconnect that. See if that makes a difference (if this is the fault, the car should also have a heavy fuel smell from the exhaust, because of the extreme rich condition). Another thing you can check is a short to ground on the injectors. The injectors are switched to ground to open them. If there is a short to ground, it remains open constantly. Please note that the injectors work in pairs, so there are always two controlled simultaneously by the ECU. The early 1UZ's have the fuel injection of a four cylinder engine 🙂

@@Carnold_YTThanks for the info I'll see if my mechanic can check these items out.

Thank you for watching!

I corrected that in part 2 of this video.

Those K10 engines are quite something, much more powerful than the manufacturers specifications. Let's hope for a sportier version of the Z12 engine, there is plenty of technical reserve for twice the amount of horsepower. Thanks for watching!

When I made this video, I wanted to show the entire process. Hence the complication.

Good luck with your new NX, wishing you many safe miles!

Thank you for the kind words, and thanks for watching!

@@Carnold_YT You are most welcome! Keep up the brilliant work 😁

That is a very good fuel economy! I recognize your remark on the throttle response, when you suddenly need to accelerate while driving calmly, the throttle response seems to be lagging a bit. However, in Sport mode this was much less the case during my test. Thanks for watching!

Thanks for watching!

Hey Mike, I think it has everything to do with the replacement procedure. In one of the last episodes before the LS got back on the road, I repaired some major rust damage to the passenger side A-pillar. It was clear that the windscreen frame was damaged (scratched to bare metal) and not properly treated before installing the new windscreen. I think this is also the cause for the leaking along the top / leading edge of the roof skin. But hey: once a project car, always a project car. Thanks for watching!

Thanks for your input, I appreciate it!

Bij de mijne is de voorruit eens vervangen, de huidige voorruit is niet goed gemonteerd. Ik denk dat 'ie daarom lekt. Is dat bij die van je opa ook het geval?

Volgens mij is deze origineel. Het lek ziet er wel exact hetzelfde uit en ook wat roest tussen de verschillende lagen metaal. Is gelukkig nog niets zichtbaar aan de buitenkant

Thanks for your comment Wilma! In regard to the safety features: in the Netherlands we have road markings on secondary roads (60 kph) that confuse every lane departure warning system. You have to switch this off on these roads in order to prevent a head on collision with oncoming trafic. That being said, the majority of the safety systems are gradually becoming better. The driver attention monitor for instance was annoying a year ago in new Toyotas. Now, I don't even realize it has such a system (as you have pointed out). Thanks for watching!

​@@Carnold_YT I am Dutch... dus dat heb ik gemerkt xx

Aha, nou dan heb ik het in elk geval even geëxplained voor de Engelstalige lezers / kijkers :-)

Thank you too Joe!

@@Carnold_YT By the way I'm usually "1st" because I'm in a time-zone + on a very different sleep schedule from your uploads. A phased "sweet-spot" that lets me see your videos 1st! on YT. FYI: I don't use a phone (sometimes for days!) nor any YT ALERT system: I always use a vanilla laptop because my eyes are older. Cheers, and "Thanks for Making" !

Well, I am really curious about that too. I have to wait until the owner can install this ECU, that will be next year...

I did mention it while recording, but I've edited that out - thanks for pointing that out. It is 4.4 liters per 100 km, or 53.5 mpg (US).

I have written an in-depth article about this engine. However, it is in Dutch, maybe Google translate can do a decent translation. The article also covers the production. Here is the link: carnold.nl/mazdas-8c-rotatiemotor-technisch-bekeken/

Thanks so much for your comment. I really missed a manual too, especially the instructions for maintenance. I have been a technical writer for many years, and I have written many workshop manuals. I thought a video would be a good format for an alternative sort of workshop manual. Glad you found it useful, and good luck with your Mash!

@@Carnold_YT Good call, this video is amazing. I've been working on scooters for 2 years now, and plan on buying a broken mash 50 as a restoration project and to get some practice for an eventual motorcycle license. This is better than a workplace manual. It might not have all the torque specs, but it has all of the experience and that's what really counts.

@@lucaspeltie Thanks for watching!

Both are quite different cars, the MX-30 would be my choice as a fun, secondary car for a two person family. The Yaris Cross is the more sensible car, but with a lot of driving pleasure. Thanks for watching!

Thanks Mike!

I am not sure about that, I know that Toyota is aware of this problem and a year ago they were implementing a solution. It is likely that it is solved with this update, but I will ask the tech spokesperson. Thank you for watching!

Toyota simply replaced my battery in a 2023 Yaris Cross Premiere.

Yes it has been replaced by a new and better battery.

@@Carnold_YT FYI, yes they did! It is a different battery altogether. I specifically asked for this.

I believe they now use a better battery, plus the software has been updated too to fix this problem

I usually do that, but due to extreme tax rates, the prices are much higher over here. That led to confusion amongst viewer, hence I chose to leave that out. Anyway, as tested this car costs € 43.190. Thanks for watching!

I am a retired Sales Manager of 25+ years with 12 yrs. at 2 Toyota dealerships. I only mention this because I would have walk-around contests with sales people earning strong spiffs. Your product knowledge and presentation is to be commended! Kudos to you my friend! GREAT JOB!!!

Thank you so much!

That depends per ecu, there are varieties within build year and market. But this is the source of all Lexus LS400 ecu knowledge: www.clublexus.com/forums/ls-1st-and-2nd-gen-1990-2000/656360-all-my-crazy-lexus-issues-solved-ecu-leaking-capacitor.html

I hope this is helpful for you 😊

@@Carnold_YT I already know I have the California +tc the last 5 of my ecu are 50040

It’s at a general computer repair place and the guy doesn’t know exactly what I want done and I’m more into the mechanical side

I usually order the capacitors according to the specs that are printed on the caps. I do choose the highest quality parts, they must be low-esr capacitors.

Thanks for your question. Unfortunately I don't have the answer. The circuit board of the pre-facelift UCF10 is indeed different. I don't know how many capacitors there are on the circuit board, but they are know to deteriorate after three decades. I think it wouldn't hurt to replace them all, just to be on the safe side.

To me, it's the perfect car - for weekends that is. It can be a comrfortable cruiser, a canyon carver and a long distance traveller.
