No vehicle speed on IQuad

[Mopar1973Man]

Foot on brake = Ground

Foot off brake = open

 

A majority of the system is setup this way.

Ok. i will switch it.  The iquad is supposed to show lockup correct?  the icon at the lower right corner of the large center gauge.

Little green dot. But be aware this is not actual lock up it calculated. Like on my truck with a manual 5 speed it does the same thing.

Hmmm, ok so maybe I was getting lockup before but because i dont have a VSS and only my transmission speed sensor it's not doing any calculating.  My current gear on the iquad always say L too. I'm assuming that since i'm not exactly stock on my setup i'm not going to have a lot of the information the iquad gives.

[Mopar1973Man]

Ahhh... That right it not going to show. Quadzilla bases that off of road speed and engine RPM's. So displayed lockup and gear information will be incorrect.

Makes sense then. Thank you so much for your help.  I made sure to donate cause you're help has been so appreciated.

@martinique78 Thank you...

 

The only advise on the lock up is to watch the tach for a second drop for 4th gear.

What is a normal cruising RPM at 70 mph?  I have 373 gears and 315 tires.  Just trying to get an idea of what i should have locked up.

Good news is I was able to tap off the ford vss signal and tie it into the wire that use to go to the dodge abs unit and now I have vehicle speed on the iQuad and it's spot on with the ford speedo and my gps unit.  Now lockup and gear info is working.  Also my indicators seem to be correlating with shifts and even lockup now that I switched the ground feed on the brake pedal switch.  Happy days!

Would you be willing to document out the wiring and everything you did to make this work I'm sure there is others out there that would like to be able to do this.

Sure!

Ford has many points on the vehicle to pull vehicle speed from.  Ford uses a tone wheel on the rear diff to run the speedo, cruise control, and ABS.  I found the easiest point for me to grab a VSS was at the cruise control module.  It's a Grey/Black wire.  I simple tapped a wire onto that wire and tied it into the White/Orange Pin 27 on the C1 plug on the PCM.  Once that was done I has VSS on my iQuad display.  Luckily my gearing and tire size allowed it to be dead on as far as speed.  It's actually more accurate to my GPS by 2 mph compared to my dash speedo.
