Keep in mind the best engineered parts in the world are still supplied by the lowest bidder

Just wanted to let all of you guys know we have the option to disable the engine's auto start stop function in our custom tunes. Should you want to get rid of that annoying little feature AND give your trucks a little bit more va va voom. 
If you're interested we have had peak gains on 93 octane of 73whp and 48wtq, maximum gains of 146tq @ 2800rpm and 80 whp.
Just an option for you all

In principle, I don't care about Auto start stop one way or another. I have driven rental MB's in Germany that had it, and it worked ok. I won't debate the mileage improvement because I have never compared.
But, Ford's implementation seems pretty rough. It reacts quickly enough. There is no way I can get my foot from the brake to the gas before it is ready to go.
However, it seems to work or not work at random, and under exactly the same conditions. No wheel turned, nothing different. Light 1 on the same road, it works, light 2 100 yards down the same road, it doesn't.
It also has a bad habit of cycling on and off at a light if I even relax my foot pressure just slightly. IT is like it is too sensitive. If I shift my foot because of a long light or train, it starts back up, then shuts off again very quickly. So far, my record is only 4 start stops in one light, but I am trying to go for the gold. It is incredibly annoying.
Short of jumper wires (no pun intended), I am wondering if are other ways it can be disabled?
When I test drove the truck over night, running several errands putting about 45 miles on it, the A.S. didn't work at all. Every light I came to, the indicator light for non- function came on. I had not pressed the on/off switch. In fact, I tried to cycle that switch to see if could get it to work and it did not.
Then, when I picked up the truck, it worked normally from the time I waited to pull out of the dealer lot.

Will I take it in for that? No, just a waste of time. They will not be able to find a problem and tell me its fine.
I dont mind using it but the brake is too sensitive, If the road is not level I have to hold the brake harder and the truck goes off.
They have more tweaking to get it right and the switch should be an enable or disable mode. Such a simple fix.

To disable the auto start/stop feature you need to jumper a wire on the on/off switch on the radio bezel. This will make the system think the button is pressed to off each time the engine is started. To remove the bezel just pull up on the tray on top of the dash. Remove the 2 7mm screws under the tray to loosen the radio bezel. Pull the bezel off by pulling from top to bottom. Either unplug the wire harness to the on/off switch or push the switch out of the bezel by pressing the tabs in on both sides of the switch and push it out. Jumper the purple and white wire by either splicing a wire between the 2 wires or shoving wire in the back of the harness until its secure and wont move. A piece of safety wire in the socket is less permanent and can be removed easily.
Just an FYI--I follow the Range Rover Sport forum. Someone compared gas mileage with start/stop active, vs disabled. The gas mileage was virtually the same. I would be concerned about excessive engine or parts wear with start/stop active. I use a soft touch on the brake pedal to keep engine running.
Because it is a ridiculous, needless feature that solves no problem and only puts more wear on your engine components.

So, I tried the disable trick on the stop/start on my truck today and it absolutely did nothing.
Round 1- I jumped the wires with a paper clip I made into a "U" to bridge between the purple and white and fired it up. Light on the dash switch says off, display comes on automatically saying stop/start is disabled, everything looks good so I put the dash back together and head out to run some errands. Pull up to the first light at the intersection and truck cuts off as usual. What the heck??? Look at the dash switch and it's not lit up saying "off" anymore. Take my foot off the brake, truck fires up and I pull away normally. Few seconds later light is illuminated on the dash again saying "off" and screen pops up saying stop/start is disabled. Loose connection, has to be right?
Round 2- Pull back up to the shop, pull everything apart and check the connection on my jumper wire. Looks good but to make myself feel better I pull my jumper wire, check the fit and try again. Looks like it's working but before I put the dash back together I take a quick trip around the block with everything loose and not buttoned up just to check. Pull up to the stop sign truck shuts off like normal. WHAT???
Round 3- Pull back up to the shop check the jumper wire - snug as a bug. Pull the jumper wire loose and throw it away. I'm then thinking to myself, what if I just leave the switch unplugged just to see what happens??? So, leaving everything loose again I fire the truck up. No display of any kind pops up on the gauges. Hmm... Maybe this is the answer? Maybe I can buy a hazard switch from a V8 truck, eliminate the stop start and the console button all together. Fire it up, put the truck in drive, pull up to the stop sign, push brake pedal to the floor, truck cuts off as normal. Beat head on steering wheel for a few seconds, release brake pedal, truck fires up and away we go.
Round 4- Pull back up to shop, put truck back together as stock, accept defeat.
Only thing I can think of is it's already 90 + degrees here in Austin and the A/C sensors must override everything else.
I'm thinking of changing my screen name to "Push Button Ron"

Did you try to use a piece of wire instead of a paper clip? I wouldn't think you could get a reliable connection through a paper clip. I did this to my truck and never had a problem but I completely striped a piece of wire about 3/4" long and shoved it into the harness with the purple and white wires (or whatever color they are). I think it's probably best to use copper wire instead of a paper clip and the shorter the better.

I can try I guess. What's crazy is I can get it to work, I just can't keep it working.
I thought about seeing if I can buy a V8 hazard switch with no start/stop button and if it works, just buy a tune and eliminate the whole thing.
I really don't mind the start/stop when it cuts the engine for 60 seconds or more and I feel like it's actually doing something constructive. But, with the temperature up here and the AC on medium and above, it only cuts off for 10 -15 seconds which is totally pointless.

I used a toothpick
Just push in the botton and insert the wide end of a toothpick between the botton and the housing .just use a piece about 7mm long .
