i have the 6pos from ts performance and it is the bomb, i really dig the 140hp tune lol got it from beans deisel i think, it was about 300 if i remember right

 

I have a Hypermax chip that came with my truck when I bought it. I think the guy said it was a 50 horse, but not sure. He said he thought it was burned up, and that is why it was not in the truck. Is there someone in here that can check them and see at a reasonable price. If it did show up burned out, could they revamp it with their specs? It is a Hypermax that just plugs directly into the computer, not a handheld job that just plugs into the OSB port under the dash.

 

See about DP Tuner or Tony Wildman or Power Hungry Performance. They might be able to set ya up.

 

Power Hungry is awesome!

 

What about for those of us with lifted trucks who need to reprogram the speedo because of larger tires, reprogram for a rear gear change and to change the shift points because of larger tires? I have been looking at the Hypertech 42001. Any stories?

 

I have larger tires, PHP works for me...

 

I didnt see a program on the PHP site to recalibrate the speedo due to the larger tires.

 

UR Right, had to do it manually..

Recalibrate Your Speedometer After Changing Tire Size

There is no tire size/code chart because tire size vs. actual tire dimensions are different between manufacturers. Even between the same tire size and same maker there will be a difference in actual size between the different tread designs.

The Ford calibration equation is:
20186 / tire height in inches = some number, then: some number /.6666 = program code

Example:
Start with 20186, divide by actual tire size in inches. Divide again by .6666

You want to use a rolling measurement to get your actual tire height (If you try to measure the tire in the driveway, use conversion charts, or anything else you will end up with an inaccurate reading again). Use your rear tire since the sensor is located there. Mark the ground and your tire and roll forward 3 times marking the ground each time. (I ran over a spot of oil at a local gas station and measured between my tread mark prints), then divide that number by three to get the average length of one revolution (this will protect yourself against a bad reading using just one revolution). You can then divide the length of one revolution by 3.14 to get actual tire height. Be careful in your measurements, a small amount will change the code. EX: 31.69" tire height is code 956, and 31.21" tire height is code 970.

Now, to program it into your truck:


Warning: You can only change the calibration 6 times without replacing the module.

To set the calibration, ground the single wire connector under the glove box it says PSOM (Programable Speedometer Opdometer Module). ”Yes there is only one and it has a spade type plug on the end". I used a wire with clips on both ends to ground the plug to a screw under the dash or try a test light and use the clip end to the PSOM and the other jam in a door hinge. Now look at your speedometer on the face of your dash while sitting in the drivers seat and there should be a "reset" button and a "select" button. While holding the reset button in on the trip meter, turn the ignition to 'on' while the wire is still grounded. Let go of the reset button. The speedometer display will sweep once and will show a code of some kind then push in again the "reset" button and the existing code will be displayed with RECAL?, mine said 976 RECAL? Now you enter your new code you came up with by dividing the rolling measurement by PI or 3.14 by pushing the "select" button until it gets to the new calibration code number. You may have to push “select” a whole bunch of times until you get to your code. If you turn off the key at this point the original code will not be changed or any of the 6 lives will not be used. To store your new code press “Reset”. Turn off the key. Unplug the ground wire. To check the new calibration, use the mile markers on the interstate. Run an indicated 60 mph and it should take exactly 60 seconds to go 1 mile.

You don't need to reprogram the speedo for different gears. Same speed sensor and everything. I swapped from 4.10's to 3.55's with no change.

For bigger tires you have to measure the outside diameter of the tire, jump a certain wire in the cab, and then use the buttons on the gauge cluster to change it. Don't remember exactly how.

 

BF, the instructions to do so are in my post above...

Been there done that, it works...

 

since were talkin tire size and gear ratios, i got a 4 inch rough country lift in the f-250, i got 35s on right now but i was thinkin some 37s to fill the wheelwells a bit more, i got 3.55s think its a good idea? i should be able to clear em without rubbin.

 

If you have an auto then it might be rough on your tranny to go 37's with 3.55's. i think i would like 4.10's for 37's personally..

4.55's will give you stock tire rotation speed with 37's. If you do the equation, a 4.33 should be the exact ratio but I would bump up to a 4.55 because of the additional rotating mass of the 37's
