Introducing the ultimate powertrain management system for the Toyota 2.4L. The X-One has been designed to take complete control of the injection and ignition systems to allow absolute management of powertrain operation without upsetting the factory ECU and its diagnostic systems. This enables the X-One to adjust every aspect of the powertrain calibration including rev-limiter extension since it drives the injectors and igniters directly as a true ECU.

Allan Phillips Racing and Dezod Motorsports has engineered a complete system that unleashes the reserved horsepower in your Toyota 2.4L powertrain.


A true parallel processing ECU with extended Rev-Limiter

Adjustable Soft-Cut Rev-Limiter Control (internally limited to 6500 RPM). Increased rev-limiter calibrations (up to 7800 RPM) are available from Authorized Dealers for highly modified race engine that are designed to handle the increased loading.


True Plug and Play Technology

A full wiring harnesses is used to adapt to system into the vehicle. It simply plugs into the factory ECU and harness using OEM connectors. Utilizes all factory sensors with the option of using high performance aftermarket sensors as well.

Complete Fuel Control

High-resolution map tables (20 x 24 cells) enable precision fuel adjustments during both closed and open-loop operation. Calibrations for oversized mass air flow sensors (up to 900 cfm).A sophisticated mass airflow based fuel controller senses OEM injection, desired air/fuel trajectory, WRAF sensor feedback and many other internal signals.

Calculates injector and igniter updates 200 times a seconds to provide high-bandwidth control. Forced-induction compensation up to 200% engine load and 7800 RPM. The table ordinate breakpoints may be adjusted to accommodate any range. Users tune the commanded air/fuel table with adjustments for trimming and dynamic fuel compensation. The calibration is entirely based upon engineering units (no fudge factors based upon injector duty-cycle, or MAF/ECT voltage). Advanced forced-induction auxiliary injection system controls secondary port and throttle injection. This control option enables the ability to keep the factory injectors stock with high quality performance, drivability and emissions. The oversized main injector function allows the replacement of the stock injectors as well. This control activates the secondary injectors based upon load calculations with a calibrate-able distribution between the port and throttle injectors (chemical intercooler feature).


Complete Ignition Control

High-resolution map table (20 x 24 cells) enables precision spark adjustments keeping the OEM knock control intact for durability. Mass airflow based load calculations accurately senses the cylinder conditions for precision spark delivery to 0.1’ (36 tooth accuracy). Spark advance and retard capability allow for modified intakes, exhaust systems and forced-induction configurations.


USB High Bandwidth Acquisition System

The power of USB unleashes the data acquisition capabilities normally found only in expensive high-end systems. XTune can capture over 100 parameters at 100 Hz for 100 minutes of data recordings.

18-Channel Auxiliary Measurement Port

In addition to the internal 18 sensor channels, the X-One includes an external 18-channel auxiliary data acquisition port. These channels are available for auxiliary measurements for pressure, temperature (RTD), thermocouples, UEGO and digital mass airflow sensors. All together, the XTune software package includes 36 sensor channels that allow for advanced data acquisition analysis. Included with X-One is a generic harness for connecting auxiliary measurements.

Dezod Motorsports notes on testing of this system over the past 10 months and over 30,000 miles...

We have extensively tested this system on a Dezod S1 Turbocharged 2008 Scion tC with 550cc & 850cc injectors for the past 10 months and 30,000 miles. The system is about as close to a stock turbo'd vehicle one can get without being stock turbo'd. The part throttle response, tunability along side the WOT control is unreal. It holds AFRs to 0.1 AFR point of accuracy. It's astounding actually!!

We here at Dezod Motorsports make this system come complete with a modified unit, a custom wiring harness and a start up calibration for your tC. We have done extensive testing on multiple boost levels from 5-14 PSI and injector sizes from the stock 310cc to 850cc injectors and all have worked excellently! So if you would like a base cal to start with, please let us know your injector size and we'd be glad to get you something to get started with.

Lastly, to further prove our point, that this unit works well, we had even taken this turbo tC on a 8 hour road trip. The tC had managed to get BETTER fuel economy than stock; with still running a 14.65:1 target AFR while in cruise like the OEM does. 4 miles/gallon more FTW!!!

In all, if you are looking to build a fairly wild street machine and keep the car as close to OEM turbo'd feel (like an SRT-4), then this unit is it! With rev limiter changes, top speed changes, built in shift light...It's the cat's meow.

Note the unit comes with a PNP harness and base cal for your tC!

 

you guys are awesome

edit
.. 1800 sigh

 

whoah! the long awaited.. those people who tried it should chime in already!

 

This has been almost a year in the making.... :?

However, this should silence the nay-sayers..

 

Screen shots!


Maybe software link?

Great work guys! NOW WERES TEH ALPHA!

 

http://www.aprpower.com/ecu_downloads.html

 

So what's the price tag?

 

woooooooooooootttttttttttttttt!!!!!!!!!!!!!!!

what seemed to be a mythical creature is now a reality...good work guys

 

Software link:

achmed the dead terrorist comes to mind for some reason...lol

silence....I kill you!!!!

 

$1800 with harness

 

thats awesome.. and cel free/OBD compliant like everyone expected?

 

More info on inputs/outputs

wideband, boost
boost control, meth control, nitrous control

 

Best things come to those whom wait. We ALWAYS follow through on our deals. It was coming out all along....

 

CELs are still a possibility depending upon how you tune it. It will still show CELs for misfires, system too rich or lean etc...

 

Software Windows seven COMP? I installed twice so far with errors!

 

Also, Does this offer Injector batt offset table rescaling? DBW idle control? Forced open loop tuning?

I guess what makes this any better then a emanage ult?

 

Boost control will be available on next software release


Q. How many additional sensors can I hook up to the X-One ECU?

A. 16 analog and 2 digital.
Q. How many channels and how long can I log with the data logger.

A. 100 channels at 100hz for 100 minutes.

Q. How does the X-One deal with fuel cut?

A. All of the calibration work has been done to keep the factory ECU content, all you have to do is tune for you specific configuration.
Q. Can you raise the vehicle speed limiter?

A. Yes.
Q. What external MAP sensors does the X-One ECU support?

A. Most all 0-5V sensors, just enter the slope and offset (or polynomial) and your in business.
Q. Does the X-One support wide band Air Fuel Ratio meters?

A. Yes.

 

I'm happy to see this become a reality for you guys. Too bad it's just not in my budget. Awesome work regardless!

 

Def windows capable. I have it running on my Sony Viao Laptop (XP windows)
