[Silly Little Cars] 2007 Go-4 Governor

Thu Apr 14 07:33:13 PDT 2016

The answer to your question would be subjective. What result is the person wanting? Governor or no governor? Top speed or top speed limited? Quick fix or proper rewiring? etc....
When wiring the injectors keep in mind that the ECU tells each injector when to open/close and for what duration. So one needs to look at the schematic for the Ford engine or the Hyundai engine and wire accordingly. 
What screws with the ECU is the O2 sensors readings being out of specs from what the ECU expects. This is a result from the injectors being misfired (kept closed).  This throws the ECU into trying to compensate for the errors. (Mixture is too lean. O2 levels go out of spec.) This won’t “kill” the ECU, but does cause it to keep trying to fix a problem it can’t. Because it doesn’t have full control of the system. And that is what leads the ECU to ceasing proper function. If one goes to the trouble to hooking up an OBD tester to a GO-4 (yes it is possible). You’ll most likely see the codes for injector miss fires and/or O2 sensor reading out of range. These errors set the ECU to turn on the CHECK ENGINE light.  (SIDE NOTE: If you check the light socket in the instrument cluster, it probably is missing the bulb. Mine was.)   This is due to the governor shutting down the 2 & 3 injectors.
So, after disabling the governor for a while and test driving for about a month. The “best” solution for me was to hook it back up and set top speed to 65-70 mph. Never hitting the limit doesn’t cause the governor the misfire the injectors, thus no codes. The ECU is happy and it runs like a champ.
Hope this helps.
Later,
Mike

With white and pink spliced together It works with the governor completely unplugged, also works with it still plugged in (in both the with ground and without ground configurations).   Whole point of my original post is to get input from the community on the absolute best method and why….

I don't want to screw up the EMC, so let me get is straight. On your first suggestion:

"Pink and White tied together allows the governor to be disconnected entirely, and restores the engine to stock as would be in an Atoz car..."

So, this is leaving the governor box plugged in, cutting the pink and white wires, tie them together (on the wire harness/connector side) and cap the pink and white wire on the governor side. 

Correct?

  Red goes to light, pink is injector power, white to injector 2 and 3, yellow is Speed Pulse, Orange is ECM power, and Black is ground.  Pink and White tied together allows the governor to be disconnected entirely, and restores the engine to stock as would be in an Atoz car as was explained to me.   

  Capping off the black wire will also disable the governor function and is what most people do, however I have heard reports that it can eventually screw up the ECM.   

  The governor on mine only has 5 wires (no orange ECM wire)… I have successfully disconnected just the yellow speed pulse to it and taken it for a test run and seems to work just the same as disconnecting the black ground…

  Unplugging the governor entirely and splicing the Injector Power to the Injector 2&3 (pink and white) also works as stated above, and seems to produce more power (but also seems to slow down much quicker when the gas is let off).

  I see 6 wires.  What's the yellow one to and do you disconnect it also?

    Bingo we have a winner

      Is this the governor?

          Outside the electrical accessory box (where the governor resides) there is a connector with a purple and a white wire (coming from the injectors) and the other side of the connector goes into the electrical accessory box and feeds the governor. I simply unplugged the connector and hot wired the purple and white wires together.

          I have to do the same, so curious...

          Can you describe further the wire splicing with the purple and white wire?

            Hello, I have a 2007 Go-4.  Looking for input on options to disconnect the governor and the best way

            The governor has 5 wires to it, 

            Injectors 2&3  (white)

            Injector Power (purple)

            Ground (black)

            Warning Light (red)

            Speed Pulse (yellow)

            I had disconnected the governor by caping and stowing the black ground wire and it seemed to work well enough and I was able to achieve desired speed, this is the only method I have found recommended on internet sources including this one.

            I have also tried it by disconnecting the Speed Pulse as well with the same acceptable results as disconnecting the ground.

            A friend showed me a third way a couple days ago, and that was by splicing the Injector Power to the Injector 2&3 (purple and white) wires together.   This seems to work really well as well, in fact there seems to be more power on the lower end accompanied by a deep throated vroom.

            Looking for advice, input, warnings on the various methods, as well as other methods.

So, you're saying you basically disconnected all wires going to and from the governor and crossed the purple and white wire together so they seem to be at a dead end?
