Ok so I know there is a happy little pulse width modulation signal that goes to the ECU to tell it how fast you are going. I have heard this is a purple wire with white tracers. I have heard you can cut this wire or add a chip to reduce the pulses and lie to the ecu. I know it triggers the cel but I have suspicions it throws the ECU into safety mode as well. Anyone got better info?

Its probbaly pretty good to do it for high revving engines, but for engines that run on VVT its a terrible idea cause thats wat tells the ECU to activate the VVT system.
So, bad for 4age ST and Beams engine. |
