When you say "bumpy" you mean it slips and engines is over revs? I have an ideea or two regarding different issues with A750.

Hi! I need to know exactly the pinout for the MAP sensor on 1hdfte. There are 3 wires: - blue/red, wich on diagram it has a note with VC -pink/blue, on diagram is noted with PIM -brown/white, noted with E2 on diagram I presume that blue/red is 5 Volts suply, pink/blue is 1 to 4.8 V signal...

I had calibrated max close to factory specs. To exclude any doubts I gave up to genuine VNT control and I use a VNT controler from these guys : www.tuning-diesels.co.uk My opinion is that VNT on our big 4.2 engine is worthless, except when you want to squeeze all the potential.

Yes. Please check picture in the firsts posts.

Not good enough! I kept the Unichip initial settings. What is your opinion about all these?

Thank you!

Hi Thor, unfortunetly I do not have a positive answer for you. I have tried every kind of tuning without succes. I am looking to buy an ECU from Australia, Graeme from GTurbo thinks that it will work. I have not found a serios supplier for an ECU, I tried Facebook and here on forum.

Looking to buy ECU for 1HDFTE with 5 speed auto (part number 175800-6441). It is for Australian and Russian posy 2003 version. Post here if you know somebody that has this part for sale or some good ideea where I might find one. Thank you! Tel +4076526652

There is absolutely not necesary to have an intercooler in to a standard 1hdt or 1hdft. If you intend to raise boost above 15psi and to tune the injection pump then an IC is a must. FMIC would be my choice. PDI are having complete kit, very easy to install even with average mechanic knowledge...

Go with a GTurbo (https://gturbo.com.au) my choice would be BadBoy specs. This turbocharger with good injection pump tune will improve the drivability of your truck to modern standards. It wont come cheap but you get more than enough for the money spendt

Hi, I am looking to buy an ECU for a 5 speed automatic 1hdfte 100 series. Must be australian, NZ, SouthAfrican or japanese specification. Ideea is that european (UK included) is excluded. Thank you! Offers and/or links here or in private. Thank you!

New goodies, VNT control box for best control of variable vanes. The box has MAF recalibration function also.....will see what changes can be done.

Those figures are just an example of what this engine in standard form can provide. Those figures are not for me! 5 speed trans auto on my car can barrely suport 600-650 Nm. I will not exceed this figures. But what I want is to have the max torque starting with 1600-1700 rpm, you now how this...

I have upgraded the turbocharger also (intercooler, exhaust, intake pipes) and my complain is that whithout a serious increase in fuel , the engine is running very lean. I monitor intake temp as well and I have 5-7 * C above ambient.

Agree with you on one side but on the other side this sistem is very reliable and in standard form (only injector upgrades) there are some nice results with over or close to 1000Nm and over 350 whp. Very easy to have 750 Nm and 300 whp. Unichip Q+ installed in my car controls fuel by...

I wrote email to Adonis, I hope they answer after they come back from Dakar. Ideea is that I need a device that offers me tuning (adjusting) capacity.

I red that your truck is '99 so it has nor DPF neither MAF sensor and almost certainly you have clasic wastegated turbocharger. If no funny noises coming from engine (like injector rattling) and no smoke under load, the first thing I will check intake pipes for leakeges (see youtube for...

Nobody has any info that might help me understand how the Injection Pump is managed by ECU on this LC model?

Of course I now them. Actually I will meet Razvan tomorrow , there is this barbecue winter meeting with all 4x4 enthusiasts around Bucharest. Would you like to join us tomorrow, from 9.30 AM? And Alex is taking care of my TOY's. Also the red turboed 80's from the picture above is still...

If IP and injectors were never refurbished, repaired, 300.000 kms is enough to have some tear that can produce fuel starvation at high load, especialy the lift pump inside the IP. If you do not want to remove IP and injectors, you might try to insert an electric fuel lift pump inline with...

15" wheels, 10" width with external bedlocks, 35's by 12.5 tyres BFGoodrich MT. I remember that only some 1hz axles support 15" diameter wheels without spacers. I have turboed myself and I advice to do yourself a favor and get a decent turbo for your 1hz engine. It is not the turbo that kills...

:))) Mosilor-Foisorul de Foc area, Calusei Street. It would be my pleasure to have a chat around our prides and joys! You have to know that I am a previous owner of FZJ80, HZJ80 and turboed HZJ80 also.....I really can not give up to LCs

All went pretty well with hardware....not straight forward but okish. For anywone that want to do something similar I can advice....just ask. The VERY HARD PART came when we took the car on dyno to adjust fuel delivery. First I used a module from DTE but tuned by Gturbo...succes was only after...

After I studied a lot the aftermarket turbochargers fabricators for this model and I decided to have something from www.gturbo.com.au, a very reputable australian turbochargers producer. I agree with them that they can upgrade my turbocharger to one of their model (BadBoy, wich is something...

Hi, I writing this down because I want to share my experience on tuning this engine and also cause I am out of ideeas. The car is the one from signature: TLC HDJ 100, 2004, 1HDFTE, Automatic 5 speed, european version, EURO3, MAF sensor present and VNT Garret Turbocharger. I really like the...

Hi Clive, usualy I can be found in and around Bucharest. Here are some photos! I have answer late because I realise that I have no photo with the car in its normal state....only during different upgrades.

My name is Cristian, I own a LandCruiser HDJ 100, 5 speed auto. I am in the process of gaining more power from 1hdfte from my car, list of mods are: VNT GTurbo BadBoy Specs, front mount larger intercooler and upgraded intake pipes, 3'' straight exhaust, Unichip Q+ Currently the Cruiser is my...
