Have you guys heard of this unit yet? Its been talked about for a little while now on skylinesaustralia.com as its outta of australia, from one of the original designers of Autronic i believe. Its supposed to be a better overall unit and has direct plug in capabilities for virtually all makes and models. (yay for skyline owners!) Talked to Cam about it, and Lightspeed in Red Deer is currently the only registered dealer in canada. much more affordable than the autronic which was the unit i'd be tussling with getting for a year now.
I'm going to have mine installed next week and tuned hopefully for the skymeent GTRC puts on every year on June 28.. Can wait for that launch controller |

Manufacturer: Vi-PEC
Category: Engine Management Systems
Description: V44 Model ECU
(there is also the V88 you can read about at the website)
http://www.lightspeedinnovations.com/default.aspx Scroll down for the links
The ViPEC V44 is our budget model. Despite this, the V44 is very capable with control of up to four variable cams, support for engines up to twelve cylinders. Software has very flexible options over how the inputs and outputs are controlled, and allows the user to design their own functions to control all sorts of devices. Precise control of injectors and ignition angle are guaranteed at very low or high RPM or manifold pressures. A very high level of protection from interference and tolerance of trigger input errors has been built into this ECU, ensuring a smooth running engine even under the most demanding conditions.
Motor Sport features include: Antilag, Flatshift, Launch control and traction control in first gear.
Closed loop control of idle speed and boost pressure makes for a "factory" idle speed stability, and precise control of boost pressure. Boost control can be setup to provide a different boost in each gear or switch between boost control tables.

QuickTune Software Feature
The QuickTune feature is available for the V44 and V88 model ECU's.
The QuickTune will tune the engine with no input from the operator. The closed loop air fuel ratio table is used as the target air fuel ratio table for the QuickTune software. This table is setup with the required air fuel ratios at various RPM and Load points.
An exhaust gas analyzer or any other analyzer that provides a 0 to 5volt "corrected" output, is connected to any of the Analog inputs, this is used as the actual air fuel ratio input. As the engine is run through its various RPM and Load points the software will adjust the volumetric efficiency numbers in the main fuel table to achieve the target air fuel ratio.
At no time do you need to touch the keyboard on the Laptop.
After the tuning is complete the analyzer and 02 sensor is longer need. At any time after tuning is finished the values in the target closed loop table can be changed, and the engine will automatically run the new air fuel ratio, providing you do not make a change to the volumetric efficiency of the engine, e.g. fit a different camshaft, modify cylinder head etc...
If the engine is modified so the volumetric efficiency changes, then the analyzer and QuickTune software feature will be required again to re-tune the engine.
The QuickTune software is much faster then a good operator. It is not possible to manually tune as quick as the QuickTune . A typical engine will take less than 20 minutes to fully map on an engine dyno.
The accuracy of the QuickTune can be setup in the software from 0.5% to 5.0% accuracy. The default value is 2% accuracy, this is generally a lot more accuracy then most tuners manual tune engines.
You cannot directly connect a 02 sensor to the ECU to QuickTune.

--------------------------------------------------------------------------------
Overview
ViPEC QuickTune software provides rapid hands-tree tuning of Engine Air/Fuel mixtures. This automated operation frees the engine tuner, allowing total concentration on safe engine/dyno operation. On road tuning of motor vehicles is even possible.
This software uses a complex combination of math, including statistics, trigonometry and fuzzy logic to intelligently adjust the fuel delivery tables. Initial tuning is rapid usually occurring within 1 second. High precision can be achieved by allowing the QuickTune to operate for an extended time at each engine operating point. The operator has control over the balance between tuning speed and accuracy. Accuracy is ultimately limited by the accuracy of the attached Air/Fuel ratio measurement equipment.
The program provides visual indication of the tune status. Automatic and manual storage of tune status allows the user to monitor the tuning progress even if undertaken in several sessions. Tuning usually proceeds 2 to 5 times faster than possible by manual means. Fuel savings of as much at 90% have been reported. The considerable savings in engine life are obvious.
This program also has elaborate diagnostics facilities and allows simultaneous operation of the ECU internal data logger and external P.C data logging.[/QUOTE] |

Its a standalone ecu... what is this "hack" you are referring to?
OP you may of said it in your post, but what is the price on the unit? How well does it maintain drivability? |

Yah, Lol, i don't know about "hacking" into your 3, but maybe i was too liberal about the use of direct plug and play for all models..
While i'm sure they can hardwire your Mazda3 with the vipec it would be slightly more expense cause you paying for shop time for the install
Looks like they've developed the following harnesses for the following so far, though i'm sure they'll continue.. maybe even a mazda 3 down the road! :thumbup:
