Computer Problems with Manual Trans Swap

[pr0ject42]

I guess another option would be is if there is an aftermarket standalone ECU that is ODBII compliant. Scrap the stocker all together.

On a slightly unrelated note, do you think a JDM or Aussie gauge cluster that doesn't have the P R N D 2 1 light tree in the middle would be interchangeable? On top of that, could you just drop in your MPH speedo into that cluster to make it more USA friendly?

 

[70sguy]

The clusters are the same, the 5spd unit has a blanking plug stuffed in where the ATM unit has the PRND21 lamp assy
Best to keep the stock cluster in the truck IMO.

I haven't wheeled much in my 80, but absolutely love having the 5spd tranny in my HDJ (Could use another gear for cruising though!)

I DD a Tercel now and it's got a manual tranny, too.

I guess I need something to keep my left hand (Right hand in the US) busy while driving.

My wife appreciates it as it keeps my hand preoccupied with shifting while driving instead of doing something harmful to her.

Alan ran with the check engine light on! He also had a Safari turbo on the truck. Over the years that morphed in to several other projects.
It did run well.

In North Carolina there is a rule that if your vehicle will pass the emmissions test and the MIL is on but related to a non-emmissions issue (such as transmission) that you can get a waiver if the repairs to correct the problem will exceed a certain amount. I'm sure if you took your LC to the Toyota dealership and told them you wanted a quote to replace the manual transmission with an auto it would be a big bill. Then you could take that to the DOT and say "look here, it will just cost too much to fix!" and you have your wavier. Now, in reality that might not work out like I have described, but it could. It just bothers me that the MIL will come on for things other than emmissions related problems.

 

[TrickyT]

The majority of all OBD-II PIDs in use today are non-standard, i.e., manufacturer specific. Newer vehicles have a ton of PIDs not related to emissions. When they do the emissions test in NC, do they plug into the OBD-II port and read out the codes? If so they would easily see that the P0700-series are all manufacturer specific and, by definition of the OBD-II standard, therefore not emissions related..

 

[mathamattox]

Good point TrickyT.

I guess the manufacturers found the MIL a convenient way to relay warnigs about all kinds of vehicle systems, but I agree that manufacturer specific codes should not apply to OBDII requirements as the whole idea of OBDII was a unified system standard to all vehicles. Maybe I will call over to an inspection station and ask to see what they say.

Have you tried getting a 5spd ECU out of AUS or Europe?
General Market EPC shows
89661-60340 for 95/01 up Computer, Engine Control FZJ80 LHD 5F EFI
Japan Market EPC shows
89661-60300 for 95/01 up Computer, Engine Control FZJ80 MTM (RHD)
More than likely the only difference between LHD and RHD ECU is mounting brackets.

You will need General Market EWD 232F if you want to cross reference the differences between ATM and MTM and understand how they relate to the Engine ECU.

May the force be with you.

Would that EWD have something as simple as a pinout diagram for the connections to the ECU and what those wires control?

You must pardon my blatant ignorance with the FSM layout, but it seem that if it was as simple as lining up the right wires to go in the right slots in the connectors coming into the ECU, it should be somewhat straight-forward.

Where would one go to pick up that EWD? A little comparisons now could tell if the ECUs are a straight swap or a little fiddling might be required.

why about just keep the auto ECU and harness conected .. set it in D and bypass the neutral safety switch ..? so you can turn it on in D .. ( the engine )

cruiserdan,

I'm not sure what wheeling hard is to you, I am a novice at off roading. To be honest, off road the 1fz and auto box work very well. My friends 80 drives just like a tank, thing will do anything as long as there is traction.

I dont want to start the big auto vs. stick debate here, that is a hole nother can of worms, but its the daily driving where i miss the stick shift.

as for the swap, any possibility of getting an overseas harness and ecu? Then many only re pinning the plugs that tie into the body harness would be necessary, as the ecu/engine harness would be plug n' play. I am sure its alot more complicated than that.

Any source for the pedal bucket, master and slave cylinder. I remember looking up the p/n for a 1fz manual trans slave cylinder, toyotapartscheaps database dident have it.

cheers

I checked my EPC on the PN's that Sheldon mentioned and they were like $800US.

And there are not many 5spd 80s here, especially for the FZJ.

Your best bet might be the Aussie brethren where the sticks were more common than in Japan.

As for the pedals, etc... I think your best bet would be trying to get them new, unless you can hook up with someone in the LHD countries that have access to used parts.

Good luck!

I snapped some photos of the H151/t-case combo I've got just for posterity sake.

Index of /fj80/H151

 

[70sguy]

That's different than my HF1A.
So the lever controls H-L function obviously.. what controls front drive?
My HF1A has a servo motor on it just like the Full time case CDL motor, but it controls front drive..
what controls front drive on your case?

 

[pr0ject42]

After talking with Tapage and seeing a photo of the shifter in his wife's rig with an H151 in it, apparently on this guy you pull (or push, I forgot) on the t-case shifter to put it into 4L.

I tested this last night and indeed that seems to work. So in the "home" position, it puts it in 2L or 4L, then you click the lever and it puts you in 4L.

This thing is a heavy bastard too!

Is it possible to source clutch master/slave, clutch disk and cover, pilot bearings, T/O bearings, shifters and what not from Canada? I've still got a lot of details to deal with before even thinking about putting this thing.

 

[70sguy]

Dual function stick, cool.

I got my Toyota 1HD-T Clutch, PP etc from the USA Toyota Dealer.
Shifters, knob, console, boots, Clutch pedal, Master and Slave, lines, hoses, brackets all new parts from Dave at Japan 4x4.
You need Toyota EPC to go down this road.

Me want!!!

wife manual FZJ80 t-case shifter .. ( HF1A )

 

[Dave 2000]

AFAIK OBD II was mandatory in the US after 96 right? This is a page 80 Series Info from 'Marks adaptors' it shows the US had a petrol engine manual gearbox so the ECU ect should be available.

Sheldon,

That is a beautiful piece of art!

Never seen that before!

FYI/FWIW/AFAIK, the US-spec 80 didn't come with MT.

 

[Dave 2000]

hmm you learn something new every day, interesting in the UK the auto's were dropped because the 'serious' off roaders only used manuals.....

Ok....now where did I put my flame proof underwear?
