I'm currently running the JR M45 supercharger kit on a 2004. Is there plans to release a kit for my car or is there one already? I'd like the ability to actually tune it. Powercard just isn't cutting it anymore for me.

 

You might want to do some reading on the Adaptronic board here. I've got my NB running turbo on one and another 14 or so have just received their Adaptronic units this week.

 

Indeed, the trick with your car is the variable intake cam timing. Presently, there's no mechanism for closed-loop control of this mechanism in the MegaSquirt, so we may not see a plug-n-play MS for the '02+ cars. It's possible to create an open-loop drive of the VVT (by hijacking the EBC driver) however this means that at positions other than full advance or full retard, cam timing will vary with temperature and oil pressure. Better than nothing, but not perfect.

There are two common ECUs I'm aware of that can drive the VVT System in closed-loop. One, as Stein said, is the Adaptronic 420. The other, which is considerably more expensive, is the Hydra Nemesis. Both are "generic" ECUs which are available with a plug-n-play wiring harness.

Your other option would be to do a parallel install, where the stock ECU is retained to do mundane things like VVT, alternator, idle, and so on, and a Megasquirt is wired in to control fuel and spark only. Such a setup is relatively common with NBs, and could be built for less than $400, maybe closer to $500 if you start with a complete pre-built MS2 rather than rolling your own.

What sort of emissions testing (if any) are you subject to? On the OBD-II cars, this is always a consideration.

 

No emissions or inspections whatsoever.

So, I'm wide open in that aspect.

I didn't realize you could do a parallel install with an MS. Got any reading info on it?

 

Well, there's not much to explain, really.

You start with an extension harness from Boomslang, which is a bundle maybe 8 or 10" long that goes between your stock ECU and the car's harness. It's just wired straight-though pin for pin. You cut the wires related to fuel injectors and the ignition coils, and connect them to the MegaSquirt. You also tap into the wires for power and ground, CLT, the crank and cam sensors, and TPS, and bridge those over to the MS. So in this configuration, the MS sees the signals coming in from the sensors, and the injectors and ignition are driven by it instead of the stock ECU. You wind up with something that looks like this:
