Things keep on changing....

Are there any new chips or ECU's for performance or mileage out there?

Any that anyone's tried?

:-)

 

no...

 

naw, not so sure about what you are talking about no.1 and i'd say just stick to the ones mentioned on here

 

Which are the ones mentioned here?
Thanks

 

sounds like your interested in a chip. I think most of the people on here are going to tell you to stay away.

Exhaust upgrades might help your MPG a little.....

 

I see.

So, maybe I'll back up a little and ask, "For $200-300, what's the best route for increasing, a) mileage, and b) performance?"

 

Help the engine breathe better and run smoother ... change you plugs if they are old, (install NWP spacers while you have things apart doing the plugs if you can afford them), add a short ram intake, and as others have stated change the exhaust, change the B pipe to get rid of the squash section, change the Y pipe both of these will help the engine breathe. All of this will cost considerably more than 200-300 but they will give you a nice start and balance delivery both power and better performance.

 

Best performance gain for less than 300 bucks are the NWP phenolic spacers.

 

Exhaust is definately the best place to start but IMO power should be the last mod. I would work on the weak points of the car, not the strong points. However, an intake and exhaust seem to be exactly what you want. Power and mpg....

 

Thanks everyone.

What prompted my questions was hearing someone with a 'Brand-X' car, talking about how installing a chip really helped her car run more efficiently.

I guess Nissan did it right before to begin with! :-)

 

have you timing adavanced to 17* that increases the amount of time your fuel burns if it doesnt increase your milage and response ill be a monkeys uncle. cost free-20 bucks dependant on the service guy at the dealership

 

You see a lot of the handheld programmers or chips on domestic cars more often than not and normally they'll let you switch between premium/regular fuel tunes and adjust ignition timing and such according to your choices.

The only tuning options available for your Maxima specifically are complete ECU reflashes (Technosquare) and piggyback computers that splice into the factory ECU wiring (APEX'i S/V-AFC, GReddy E-manage)

 

you could lean the air/fuel ratio. then you'll be using less gas...but you might loose some power. but if you are cruising you shouldn't feel the difference.

 

17 Degree advance?
Doesn't that cause all sorts of detonation?
AND, does it really work?
Thanks!
