Hahaha! Wouldn't you love to have one of those?
Hm... Would any of you have the slightest idea how it would work?

Altho not Laptop Controled.. there are specific computer aided NOS systems.. such as..

Jacobs Ignition....
Nitrous Mastermind


If you're a nitrous junkie, install a Jacobs Electronics Nitrous Mastermind and you won't have to worry about melting your mill. The best thing about the Nitrous Mastermind is its ability to flow nitrous in proportion to rpm. You'll get more power, safety, and traction without hurting anything, even with two-stage systems. It also handles a few extra jobs:
* Prevents detonation by retarding timing on nitrous
* Ends burned pistons by shutting off nitrous if fuel pressure drops
* Stops destructive over-revving with a feather-touch rpm limiter
* Prevents nitrous from turning on under a set rpm
This unit is fully adjustable from the dash and includes magnetic pickup for use with power electronic distributors. Compatible with all nitrous systems. For use on V8 engines.

how much does something like that cost?

kanned

the Nitrous Mastermind is around 250 dollars from Summit Racing..

Nitrous Oxide Systems also makes a similar system for around 300...

psing23

is that the window switch that everyone talks about? its an additional $300 over the cost of your setup right? when i was reading it i sounded like it was about the window switch that controls the NOS and tells it when to start and stop and stuff like that...

if you were talking about the laptop system that was used in the f&f movie that was a real time fuel management system. it allows real time control of the injectors to make sure that you are not running rich or lean. Not sure what system that was, but a friend in a very moded rx-7 has the TEC-II model, very cool system for running high boost cars.

For wet systems only

Not compatable with the maximas ignition system, it wont work.

Most nitrous kits come with fuel pressure switch

Window switch...

Ive had a nitrous mastermind on my Scirocco, its a nice little piece. But it only works with wet systems and single coil systems ignition systems.

Zex and Venom also offer complete systems that work with your laptop. It gives you the customization of deciding when and how much juice you want at a specific time. The venom system is by far the best. It has so many safety features. LCD screen that tells you what the system is doing. It will disarm itself and not let you use it if the Venom computer detects anything out of range to make you
"blow up" the engine. So say for instance, you are hitting the NOS and your computer starts to get spark knock around 5k, the venom computer will recognize that and shut the system down.

This is wrong, the Venom monitors the voltage of you factory oxygen sensor for leaness and to controll the a/f ratio. It does not connect to the knock sensor of your car, it has no way of preventing knock.

IMHO an EGT gauge is better suited to tune than am OEM oxygen sensor.

I'm talking about the systems that control NOS injection, timing retarding and all that stuff.

Are there any control units/systems that work on the Maxima?

Ok.

Just so that every one knows their is nothing on the market yet that allows ignition timing retard on a VQ. The JWT nitrous daughter board does it but it is only available for 95 & 96's.

Darn...

Well since its that kind of party.......if you did get spark knock the o2 sensor would read rich.....therefore shutting down the system. Actually the system monitors much more than just o2 sensor readings.

Are you sure it would shut down and not adjust the Nitrous fuel mixture to be more lean and thus inducing more knock? Its my understanding that it only monitors O2 voltage to adjust a/f ratio. I dunno, If you go look at venoms web site it only show the O2 sensor as monitored, along with the usual suspects like RPM & TPS.

What else does the Venom monitor?

Well, this is how i know what i do. I've been real close with the guys at SVT national. Two of the people in it have the venom systems. I spent quite a few hours helping him pu t the system on the car. Every time he would attempt to arm the system, it gave him a MAF warning. He ended up having to send the brain back to Venom for tuning (something to do with model year Voltage). For what exactly it monitors to be specific im not sure. I do know it monitors most of the fuel trim settings which include:

MAF
O2
TPS
Runner Control
ECT

cya for now

I dont see a MAF wire in the install diagram, perhaps it had an issue with the way the Contour triggers its injectors? Ive never seen it, just the web site, so I'll take your word for it

What is Runner Control & ECT?
