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). With dyno tests to back up the data.
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:

I have a urd fuel timing controller for sale if anyones interested
I got my 2002 VW 4cyl turbo flash "chipped" with an APR program for $499 and got an instant 40HP on top of the stock 170 and 40ft-lb increase to 265ft-lb. That's a big kick in the pants and well worth the price.
What are we talking about for the $799 you're asking? I'm referring to the simple two fixed program "power and mileage" option.

Right now the package is for the plug and play tunable setup for people that want to tune the unit themselves.
We are working on a few tunes that we will make available for customers to download for power and gas mileage. So far with some mild street tuning there are very nice power gains across the entire RPM range and noticeably better gas mileage. We will be releasing the tunes for our customers who have purchased the EMSPowered plug and play unit to download free of charge once they're finished, or can pre-load the tunes for customers that purchase them after the tunes are finished.
So far on the EMSPowered 1997 Land Cruiser on the stock ecu we were at about 10.5-11mpg before any tuning. That is with 37" HMMWV tires with the double beadlock HMMWV wheels and runflats installed, EMSPowered rear bumper "wings", MetalTech front bumper, MetalTech sliders and 300k miles on the original motor. After some mild street tuning we are already at 13.5mpg with power gains across the entire RPM/load range with mixed highway/city driving and there is still room for some more improvement.
GIAC on a 2007 GTI here, with similar results - feels like a completely different car - but we're talking about forced induction engines, and VW tends to leave a lot on the table for tuning.
Yeah you won't see gains like you do on a FI motor because most of those chips just increase boost slightly.
But I think there is quit a bit of economy to be gained if you leaned out the open loop. I know with my truck on the dyno when I went open loop it maxed out the AFR reading and was richer than 10:1. If you bring that back a couple of points you will get more power and won't throw so much gas down the exhaust pipe.

There's also some room for more power gain with some timing adjustments. The timing map on the stock Toyota tune is very conservative.
Definitely gains to be made I was just saying I don't think you won't see 40hp gains on a 1FZFE. But I am excited to see what happens

True, specially not at the tire. These trucks have quite a bit of power loss through the drivetrain. We'll try to get some solid tuning done with dyno results soon, and start making the new tunes available for our plug and play ECU customers.
Yeah, the FI tunes increase boost pressure and how long boost can be sustained, but they also adjust the timing map.
A freeway onramp at WOT was the most striking difference. The torque was completely smooth from 0-80mph.
That, and 70mph to 90mph can happen in the blink of an eye now.
I have the TRD S/C on the 97.... Is it safe to tune with the S/C? What do anticipate the improvements to be if any with a S/C?
thanks

With the SC you should see power and gas mileage increases more than the the naturally aspirated trucks. But more importantly for the SC'd trucks I think would be the improvements in drivability.

More progress on our gas mileage tune. So far we are at 17% increase in gas mileage. More test and tune this week. Should have the final gas mileage tune ready for you guys by Monday.
Awesome news Baktasht! Is there any power loss (below OEM levels) associated with this gas mileage tune? Providing a before/after dyno plot on these tunes would be very reassuring, especially to those of us involved in the Landtank MAF controversy. Looking forward to hearing about a power tune as well!

Even with the gas mileage tune power is actually increased across the entire range. Yes, we will have dyno data along with plenty of data logs of all the tunes we will be releasing. We will make the tunes available with hard evidence and data.

My mistake. I was typing from my phone and had a typo. We are at 18% increase in fuel economy so far. Not 17.
So what are you getting MPG ewise?
How is the drivability? I am a little leary of these secrets and lies boxes, since unlike a regular standalone (which I know our vehicles complicate), you can really tune properly as opposed to intercepting secrets and send lies to the ECU? How is startup when cold, start up when hot, altitude compensation, transmission function, etc? I am not as familar with the FIC as I am with Hondata, Cobb AP, and other stand alone type units, so I am sure i am missing something.
Cobb AP? That isn't a standalone it is simply a reflash. The OEM code is hacked by the developers, at Cobb a lot of it was done by a guy named Thistle. Once the OEM code is hacked your programmer changes the code via a reflash to the values you want. The stock ECU stays in place. Only problem is no one has hacked the Toyota ECU, so reflashing this way is not possible.
Now a stand alone is exactly that, it stands alone no OEM computer and it runs everything. This gives you the most flexibility but has a lot of added cost and is difficult with the 80 since it uses a separate TCU.
So the piggyback is the best solution, it gives you control of all the things you need, actually the FI/C 8 gives you control of much more than you need. What about it gives you any concern? Why would it effect hot or cold start? That's part of the map that there is no reason to touch? The part of the map that's been touched up is the high RPM, WOT, Open loop that has the car running richer than 10:1. Transmission function is done by the TCU? I think you need to rethink what you mean when you say you can really tune something. 9/10 times when you are tuning something all you are doing is tricking the computer to believe what you want it to believe. Common example is MAF housings, in turbo cars it is very easy to saturate the stock MAF signal, so larger housings are swapped in, so you get the same amount of air at a lower voltage and then "tune" the computer for that signal. This is exactly what Cobb AP does for their larger MAF Housings.
