i saw them on summit racing. just tryin to figure out if its a bs or not
i got a 97` AT
PS sorry if this thread belongs somewhere else

JET V-Force Power Control Modules
"Improved computer technology for your import.
Using the same computer tuning popularized by JET's Stage 1 and Stage 2 computer modules/chips, these V-Force power control modules use a 20MHz RISC microprocessor to optimize the ignition spark advance and recalibrate the fuel map for optimum horsepower and acceleration. Other features include an LED readout and an on/off override switch."

Venom 400 Performance Control Modules
"Get 25 percent more horsepower in just 30 minutes.
You don't have to be a master mechanic to get a major horsepower increase from your vehicle. All you need is a half an hour, a set of hand tools, and one of Python's Venom 400 performance control modules. These Venom 400s increase horsepower by 25 percent in the 1,000 to 5,000 rpm range and reduce delay when you mash down your throttle. And because they only kick on during increased engine load, they don't affect fuel economy under normal driving conditions. They'll work with preinstalled performance chips, have an off switch to preserve smog certification when not racing, and require only four electrical connections during installation."

and another thing they have all these "RPM Activated Switches" what do they do?

 

those "modules" are a waste of money. The summit switch is to activate VI if you have a 00VI or MEVI

 

Jet........

 

No. Technosquare and JWT do something, but as usual you gotta pay to play.

REAL ecu upgrades cost hundreds of dollars becaue there is alot of programming that goes into them. These cheap chips and modules are like diet pills, they may seem to work initially, but thats just a placebo effect that wears off, and in the end you are just putting extra stuff into your car. Depending on what it does it might even harm your engine. For instance if it overrides your KS and prevents the ecu from retarding timing, the car may pull like normal, but its gonna wreck your engine.
