has anyone used one of these http://www.jetchip.com/Shop/shopdisp...ppp=10&catID=1

link did not work for me but I am guessing it is a chip promising performance or mpg gains???

Our ecu is so good at learning that with in a matter of a few days or sooner the ecu would learn what ever this chip changed. The scu would then make changes to get optimal fuel efficiency.

V-Force Plus:

JET offers a wide range of V-Force Plus Performance Modules for your Domestic or Import vehicle

For Application Information click here.

For more information about our V-Force Plus Performance Module click here.

V-FORCE PLUS MODULE FOR IMPORTS - The JET V-Force Plus features the same power tuning technology found in JET’s performance modules/programmers. The JET V-Force Plus is an inline tuning device that uses a microprocessor to optimize ignition spark advance and recalibrate the fuel maps for improved horsepower, torque, acceleration, and throttle response. The face of the V-Force Plus features backlit LCD display with built in dimmer. In addition the JET V-Force Plus allows the user to select from 14 different monitoring screens. This includes Throttle Position, Mass Air Flow, Manifold Pressure, Fuel Economy and Air/Fuel Ratio. Works great with other aftermarket upgrades including exhaust, intake, mass air, etc.

*Available for most 1990-current import cars and trucks.

Improve horsepower and throttle response
Optimized ignition advance curves
Extensive recalibration of fuel maps
14 different monitoring screens
Ability to add oxygen sensor hook up for additional monitoring
Multiple ways to mount LCD included

Will not work with the Toyota ECU would work with Honda or Subaru.

At the very least you get the scanner that will show basic engine data, like the Scangauge- thats $150 value right there. It wll probably alter some data for the ECM (like intake air temp etc.) to make it advance timing more and may be change fuel ratio. Could work, but as said before the ECM may eventually readjust to run the way it was before.

if you guys are talking about performnace chips.. i got one from yourhotcar.com its a universal one.. but its a combo o2 sensor too. it works. I have an auto tranny and it used to shift at 4800 now it shifts at 6100. it made a big difference.

Ok, so looking at the above, let me tell you, very dangerous to run.

All you are doing is fulling the computer to think it's running one way so it'll adjust accordingly. These are done via resistors.

Why is this dangerous?

Well when something does go wrong with your car, the ecu may not be able to make the correct adjustment, and you're going to end up running stupid rich, or stupid lean. Which is going to cause motor to have a little Oops! moment. Which could result in, new motor.

Greddy Emange is a better option for just a n/a. Or Camcon, SFAC II, megasquirt, or AEM standalone.

Megasquirt is probably the best bang for buck standalone, and have known many people to run it from previous cars. But you gotta figure out how to wire it.

AEM is a good standalone as well, but again, you have to figure out how to wire it.

SFAC II is great, easy to wire, but you are limited to what you can adjust with.

Camcon has shown with proper tunning, 4-5hp just on fuel curves. If you adjust timing and such, I'd say you can almost top 10hp safely.

You also have a good chance to foul the Cat sooner by running those chips/O2 sensor modifiers.

^true. Also forgot to mention to make your bumpers black :P
