Wow and I thought I was being a dick in the Mitt thread.
:newlevelreached:
That's what you were going for? I though we were just debating.
At the PCM connector, Pin 58 is a GY/BK wire (VSS input).
Interrupt that wire with a switch and your speed limiter will vanish.
When the switch is open, you may also lose your speedometer (please report back whether that happens or not).
At normal speeds, with that switch open, you will enjoy that your idle speed drops to actual idle, not that propped up 1200 rpm until you dip below 5 mph/stop. THAT'S why I want to know whether it affects your speedo or not. You can actually GAIN engine braking by doing this.
Please edit the profanity from your earlier post, so that we can continue to enjoy your presence at The Ranger Station.
Looked this one up. It will NOT kill the speedo if you place your switch close to the PCM. The VSS signal is sent to the ABS module which then sends the signal out to the GEM, the IC, the PCM, and the speed-control servo (if equipped).
Also, I was pondering this one through out the day. I think the Ford scanner has the ability to re-program the parameters and tell it that you have 4.10 gears now, thereby correcting the speedometer.
