Aftermarket ECU using VVT control?

[Huffer]

Anyone here had any experiences with this?
Things to watch for?

Thinking of using one on an EZ30 (3.0L flat six engine) with Variable Valve Timing to stretch the useable powerband...

yes I'm a novice, and yes the tuning will go on a non-turbo...

Any advice/opinions much appreciated.

Most aftermarket ECU's will claim VVT or VTEC control. However they generally use simple RPM triggers. The standard VVT advances the cam based upon engine temp, load and RPM.

Motec M400/600/800 has the best vvt cam control I've seen. Allows for a 3D table based on RPM & one other user selectable input like TP, load point, MAP,injector duty cycle,engine temp, EGT, or any of the user definable channels which means that if coupled with the ADL you can add any other compensations you want.

All the others I checked out only allow for 2D rpm based positioning.

Is this really relivent with a stand alone system tho?

you can change fuel ratios all that kinda crap already rather than the computer deciding on when to change etc.

Of course it's relevant, if you can't control the VVT the same as the factory then at the very least you may have driveability issues or lose power, at the worst you may even damage the engine.

IMHO the ability to change fuel ratios is the least important feature of an ECU, the best features are the ability to apply 3D (or sometimes just 2D) compensations to the maps, or other ancillary features like nitrous, 2 stage rev limiting, traction control and of course the ability to datalog your engines performance. Which is why I prefer Motec, the extra cost is more than worth it for the features provided

On the topic of Aftermarket ECU's etc

anyone know if there is a place in the lower north island that installs and tunes those??
Im interested in that sorta thing and im wanting to see if i cant get some desent work experience while im still on my course.
