UPDATE 5/1/2013. The fully plug-n-play setup is now available for orders. Information as follows:

We will have a few different options for you guys.

* One setup will be hardware only for a plug and play tunable setup for the guys that want to do the tuning themselves on more modified setups such as custom turbo or supercharged trucks.

* Another setup will be package with the plug and play hardware which includes two tunes that can be switched between (power tune and gas mileage tune, and possibly other tunes).


Finished the final layout for the plug and play harness tonight and tested all functionality including MAP clamp, O2 sensor remapping, ignition timing adjustment, fueling adjustment, etc... Everything is working perfectly.

Just for kicks and a quick and dirty test I went ahead and leaned out the majority of the fuel map and added a few degrees of timing in certain load areas of the ignition map. The increase in power was very apparent with just a quick drive on the side roads and highway. This was just a rough test to test functionality to make sure everything is doing what we want it to do, but the power increase was very obvious with just a couple of mild changes.

Starting today we will begin taking orders for the following:
* Complete plug and play kits including ECU

In the next few weeks we will have the following available as well:
* Complete plug and play kits including ECU and pre-loaded switchable power map and gas mileage map.

Why use the EMSPowered plug and play setup?
* It is easy to install. It all plugs right in and to go back to 100% OEM Toyota all you have to do is unplug the EMSPowered plug and play setup.
* It gives you full control over the ignition timing map.
* It gives you full control over the fueling map.
* It allows you to simulate any reading you'd like on the O2 (oxygen) sensor signal if you want to avoid any check engine lights or erroneous fuel trims.
* It enables you to properly tune for forced induction such as turbocharged or supercharged installations.
* It enables you to properly adjust for larger fuel injectors.
* You can achieve better gas mileage with the proper tune.
* You can achieve better power/torque with the proper tune.

What else is important here?
* EMSPowered will continue to develop new solutions based around this plug and play setup over the foreseeable future for the Land Cruiser 1FZFE platform.
* As we develop newer tuning maps you will be able to take advantage of them by simply downloading and loading them onto the tunable ECU.
* If you purchase one of our turbo kits in the future, you can simply load a pre-tuned map for our turbo kit onto the tunable ECU.
* The point being here, is that it's not necessarily "what you see is what you get". This tuning solution will continue to get better and better as we put more time and $$ into development of new and better tuned maps. And to take advantage of those new maps, there is no change of hardware required, all you have to do is hook up your laptop via the included USB cable and load the new tuned map.

We will keep pricing and package information updated on our website as more options get added. You can see pricing information and place your order on our website here:

Took a while digging through wiring diagrams to put together a chart. But here it is. I think this should apply for the 95-97 FZJ80 USA trucks (there may be variations of this for FZJ80's from other parts of the world, I am not sure). This is a pin by pin listing of what each pinout is for on the ECU. There's a few pins that I could not find documentation for, if anyone knows let me know and I'll add them, or if I find out later I'll add them.



Here is a breakdown of what each pinout is for. Please keep in mind that I am making these charts off of a lot of hand written notes, so be aware there may be typos. If there are and you notice one, let me know so that I can correct it.

Don't forget the old racing saying:

"There is no replacement for displacement."
 
a little preamble history before you start would be great.

I have a 94 fzj, I did not think there was anyting i could tune on my truck,

I guess just a brief outline of what the tuning issue are ... just so we can all understand where you are going with this.

For example my truck is not capable of using a scanner , so i guess thats why your doing 95 and up, so what exactly can you tune in a 95 or higher truck?

thanks!
look forward to the thread.
 
Supercharger kit?

If you mean to ask if we will provide a tuned ECU for the supercharged 1FZFE, yes, we can do that. We would need at least 1 supercharger equipped truck to come in for tuning at our Austin, TX facility first to create all the necessary maps.

This thread is just to share information that I think may be useful to others. As far as a tuning solution, there are many out there that are plenty capable of controlling the 1FZFE. Most require intimate knowledge of wiring, how an ECU/ECM works, what inputs mean what, and how a vehicle needs to be tuned. If you have this knowledge and want to tackle the project yourself this thread will be useful. If you don't have this knowledge and want a plug'n'play solution, that's what we're working on for you guys that should be available some time in the next several months. All my current notes are on the 95-97 so I'm posting those first. I will get to the 93/94 as well and post that information up as I get time.
 
what would be great is a away to tap into the pins and intercept things like oil pressure, engine temp, trany temp, and have a compact self contained clusted of gauges that can use the OEM sending voltages and convert them into a usable bit of info.

IE.. the Engine temp has such a huge dead zone, and the trans temp is just a on /off light. You can get aftermarket sensors sure, but intsalling them is an issue and you end up with huge pillar gauges.
Can we not just use the OEM sending units and interpurt there data differently??
Its my understanding that i cant use scan guage, so can you do anything there?.. this is for pre 95 of course.. ,, i feel so left out..lol

I am an AME (A&P in the states) spent the better part of my life with manuals and such, I have the wirring manuals for my 94, and a pretty good understanding of wirring, But I am a bit lacking in the Tunning dept. (no alot of tunning happening on a 747..lol)

i guess i could thread search but really did not think there was much i could to to my cruiser save some wire jumping for window function and 7 pin mod type stuff... so i am all over this...
 
I am a couple years behind on the latest standalone technology but I have experience with many different units that have been on the market. While most work to some extent, there are only a few that are truly worth spending the time and money to get to work. A couple hurdles I can think of with a standalone and the 1FZ will be OBD2 compliancy for emissions purposes and transmission control. Were you thinking a piggyback or running a full standalone system? I have had good success, possibly the best out of my list, with the AEM stuff if it matters.

Maybe the TT Supra plug and play can be adapted to work, looks like it supports A/T too. http://www.aemelectronics.com/Images/Products/Installation Instructions 30-6100.pdf

For the 95+ the goal is to leave the factory ECU in place, keep OBDII as functional as possible both for diagnostic purposes and inspection/emissions test, and still have a fully tunable setup with complete control over timing and fueling

I had 2 AEM's in my Supra (PNP) the first gen1 killed a motor after something in it advanced timing 40 deg at all points. AEM replaced the ECU and said it would be ok now and the issue was fixed. The ECU was a dude right out of the box. I pulled it out and installed a Vipec V88 no issues at all with that, car is still a DD for the new owner 3 years later. AEM IMO is total s*** plane and simple I have a $12k engine rebuild bill and an AEM door stop to show.

I'm going to try and get a little more work done on this tomorrow and possibly Sunday. But I'm at SEMA all next week, will continue the week after we get back from Vegas. The plan is to have a plug and play tuning solution for you guys by around the end of this year.
 
That sucks to hear about your AEM box troubles, was this something common? What I always find sort of ironic is that my favorite stand alone was an old school Apexi Power FC straight from Japan. Very simple and basic but it always worked, and worked well. The only real trouble was it didn't have any type of knock control capability, so it was pretty easy to blow up motors with it if you weren't careful.
