The ECU+ is an advanced piggyback engine management system for the 1990-1999 turbo Eclipse, Talon, Laser, or Galant VR-4, or 2003-2006 Lancer EVO VIII/IX that gives you complete control over engine fuel flow and timing.
The ECU+ includes a crazy (and growing!) number of features, including:
Dual fuel and timing maps with on-the-fly map switching. (Unlimited sets of maps can be saved/restored to a laptop.) +/-50% adjustment on the fuel maps and +/-15 degrees on the timing maps.
Fuel and timing are adjusted via 129-point fuel and timing maps (250 RPM resolution from 1000 to 8000 RPM at four different loads, plus idle). RPMs in-between the discrete points are interpolated internally.
Integrated injector scaling to support oversized injectors.
Supports vehicles with wrong-year cam sensors - most useful for 1995-1996 DSMs with a 1997+ cam sensor swap, or a 2nd generation DSM with a 1st generation (6 bolt) motor - eliminates the check-engine light on those setups.
Simulated front and rear O2 sensor generation.
Configurable fuel-cut defencer.
Integrated MAS tweaking capability, similar to the HKS EIDS, to improve idle with large injectors and cams.
Configurable low/medium/high load thresholds.
Works directly with the GM 3" and 3.5" MAFs to replace the stock DSM/EVO MAS air meter.
Fast native datalogging that logs at 25 samples per second.
Integrated stock ECU datalogging to log things like fuel trims and knock sum.
Multiple uncommitted I/Os for future expansion and datalogging of analog signals.
Knock back-off function to protect your engine from excessive knock.
Optional plug-n-play capability for the 1995+ DSMs and the EVO VIII/IX - installs in minutes!
Street dyno capability in the Windows software - treats a WOT run as a dyno pull and plot HP and torque.
Can "overlay" multiple runs and compare between them on the street dyno or the time plots - immediately see if your tuning resulted in increased HP or if your engine was knocking in a given range.
Drag capability - treats a 1/4 mile of driving as though it were done on a drag strip - shows 60', 1/8 mile and 1/4 mile speeds and ET
Integrated full-featured OBD-II code scanner/reader (1995+ DSMs and the EVO VIII/IX). Includes real-time display of engine parameters for OBD-II cars and for the 1G DSMs.
Launch control and no-lift shifting.
Advanced architecture - the ECU+ includes a dedicated high-speed digital signal processor (2x faster than the original ECU+) along with two co-processors for knock and other functions.
Free software upgrades for the Windows software as well as the firmware inside the ECU+ head unit - software and firmware releases are usually every 6-9 months to add new features, and most updates are available as betas for those who like to be on the bleeding edge.
Inexpensive and full-featured - you don't have to buy hundreds of dollars worth of extras to tune your car (though a aftermarket wideband O2 kit is highly recommended).
World-class analysis and tuning software for Windows 98 and up. You won't find better software in any other system. Guaranteed.
(Note that some of the ECU+'s new hardware features aren't being used by the software. The ECU+ is a community-driven development - please suggest (on the forums) what future software capabilities you'd like to see in the ECU+ to take advantage of this hardware.)
Out of the box, the ECU+ system includes:
The ECU+ head unit, which wires into your car.
On the plug-n-play version, an adapter that plugs directly into your stock ECU.
Windows software on CD-ROM, including a GUI setup program and several utilities.
A 112-page software and installation manual (PDF format) on CD-ROM.
