ECU info 1HD-FTE Motor

[TroopiePete]

Hi

After any info on the ECU used in both the Land cruiser 100 Series and Troop Carriers - part numbers differences ect.

why?
The 100 Series has Cruise Control as part of the ECU, I want to install Cruise but if it's available by replacing the ECU or just adding the switches then that's what I will do - I have all the wiring info just not the ECU numbers used in each car.. other difference is the 100 series has a chip in the key - the Troopie has not, but the wiring is there just not the electronics for it.

A complete correct wiring diagram for the 78 series would also be nice!

i dont know if it can be done or not.. but i don know the 100's have security on the computers.. so u would have to either get that disabled, or use the keys etc from the 100.. also the 100 is intercooled so would be tuned different.

[TroopiePete]

All valid points.
Often wondered is an inter-cooler would make much of a difference.
The security section is a different box that communicates to the ECU I guess the ECU may need a signal from the security section before it will work, would be interesting to give it a try ;-)

Not sure on the ECU quesion in relation to the cruise but there are quite a few differences in regard to the power outputs so swapping the ECU's around with the higher state of tune and not the engin bits to support it could be a receipe for destruction. The 100 engine has lighter pistons, different injectors, the intercooler as mentioned and internal differences to the injector pump.

Would love to hear how you go with this as putting factory style cruise into the 79 series engine in my 80 would be nice.

If I can get to my car in he next few days I'll see if there is still a part number on the 79 series ECU in mine.

Not really looking at swapping ECU's but if it was to work then that is what I may do, I guess the question is if the motor is the same why the power difference? - apart form the intercooler.

My ECU is quite clearly marked but I don't know what numbers work
89666-60380
175800-3191 12V
1HD-FTE M/T 6

By looking at the numbers the Motor and Transmission is the last line, although the 6 is a bit out of place unless it's a version number or something.

Anyone know anything about these things?

As for a 80 Series, unless you were to transplant the motor and electronics it's a tad different because the reason an ECU can control the Cruise Control is because of the Drive By Wire Accelerator, there are plenty of standard cable Cruise Controls around and much cheeper.

I don't think you quite got my post Peter.

That is what my 80 series is, the previous owner transplanted the ute version of the FTE into the 80 so it has the fly by wire throttle and ECU control etc exactly the same as your troopy

Hi

No Problem, you answered the main question as to what are the differences between the two cars.

As for the Transplant - WOW that must have been one fun job! I guess the wiring loom was also transplanted, so did this also include the Gear Box and Transfer case or were these compatible.

The 78 Series that I have is missing the cables and pins for the Cruise part of the ECU but the ECU still has the same arrangement of pins, to fully test I need to get hold of the plug pins - anyone got a spare set or ECU plug set?

I guess cracking the lid of the ECU may tell me if the pins actually have components connected, it could be just a matter of programming.

At the end of the day all is not lost if the unit is missing the Cruise section as I already have an aftermarket Cruise control that suits Fly by wire it's just missing the plug set that connects to the Accelerator but I think I have worked out the wiring, just got to take the next step and cut the cables, or get hold of plugs.

The car was originally a 1HD-T so the bottom end of all these designations (1HD) is the same meaning the engine is a straight bolt in to the original 80 series gearbox.

See you really do get edjimcated bing in groups like this.

Good thing to remember about the 80 and I guess 100 series - all for future reference.

a Friend of mine has a 76 Series V8 TD, obviously Manual Transition he was thinking that down the track an Auto out of the 100 Series would be a nice implant.
