I'm a newbie when it comes to ECU upgrades. Is this thing for real? What exactly does it do?

I know that if I was going to do an ECU, I'd go the technosquare route. I don't have the money for it and I'm afraid it will void my warranty (underwriters are hardnosed).

dont spend your money on those chips .. they are BS... just makes your gas tank go empty quicker...

save your money for the real thing...

 

It tells your computer that the intake air is coolder than it really is. This wiill give you a richer mixture and possibly more spark advance. It will hurt gas mileage and probably add power somewhere in the powerband. I have used this type of mod to fine tune mixture on road race cars (variable resistor and mixture gauge) but I wouldn't use it on a regularly driven street car.

 

can't believe people actually bid on those
