"Performance" modules

[Fresh]

that stuff is all fake believe me. look up k-pro for honda. now thats a real tuning device

This won't work on the VQ and modern ECU engines like it. It has a closed loop learning ECU, think of it like an adaptive control system such as a kalman filter. It adapts its control loop parameters on the fly accounting for changes in sensors and conditions, there is no fixed fuel map. Even on older cars they have a closed loop control based on the O2 sensor meaning all these devices do is affect the acceleration fuel map, not steady state power where emissions control is controlling to stoichiometric. On the VQ and similar however, within 20 minutes you'll be back to square one on even the fuel map. And thats assuming you don't destroy a really expensive part in the process of installing this waste of $25. All lessons learned from the Z.

Let me reiterate, these don't work, stay away from them.

There is power to be had from the VQ in the MO however. Nissan did a good job of aspirating the VQ in the Z. Both it's intake and exhaust. Many dynos have been performed on the Z aftermarket components and most net essentially zero (within measuring limits of the dyno) after about 20 minutes (adaptive ECU). The MO is not as well tuned stock. So better aspiration and the ECU will relearn to achieve stoichiometric but the additional aspiration will yield additional power. But to achieve this, you will need to modify both the intake and the exhaust as neither is as well tuned stock on the MO as the Z.

If anybody ever runs across MO dyno results especially with mods, please post them up as I have never seen any.

has anbody used an engine or haedunit from a Z in a Murano
our kiwi Z put out 220Kw against muano's 172 Kw
would there be improvement.
this is using 96 octane fuel

Not that I have read, maybe others have. And if you are talking about the VQ35DE then it is the same engine, even with the Z ECU the intake and exhaust are the major limitations here. However the Z is now using the VQ35HR. Without artificial aspiration the HR develops power a little earlier. I would imagine you would need the Z ECU, but certainly it would be best to work the intake and exhaust as well. The main question I think is the effect on the CVT. This thread may be of interest:

muranokiwibru-

I am sure that as the MO gets older and used ones can be had for less and less, someone will inevitably mod it with "Z" equipment or a blower or NOX. I hope I will still be around on this board to see it because I am curious to know how the drivetrain handles/survives the added torque.

have a look at :
www.remus.at
then look under cars- nissan- murano
it shows standard 172kw exhaust going up to 178kw
it also allows you to listen to the exhaust.
here in New Zealand it cost about $1500.
still not sure if I will spend the money but it is tempting.

Anyone use the unichip piggyback mod here?

What limitations does VQ35DE and ZECU have?? What are their differences??

The Bullydog Powerpup should work well and has several different programs to use. Not cheap but it does work.
