Apps

Well my apps finnaly died I'm getting dead peadel and a apps code got a timbo coming is there any thing I need to do extra when I put it on or just set it the procedure for the timbos

Hopefully someone will chime in, but I just followed the directions Timbo gave. I still had a small spot in the pedal at the bottom with no throttle response, so I had to adjust that screw (tighten) on the TV lever/linkage. 

 

If you have to loosen/tighten that star screw, use heat to break the loctite, or you can strip it like I did. Then I had to drill and tap and use a bigger bolt.

Make sure that you do the APPS calibration after you install it. I think that is in their instructions which are very helpful and easy as pie! Timbos apps is an excellent mod and shouldn't give you ANY issues. Have a volt meter handy when you adjust the idle screw to watch the voltage.

APPS SENSOR INSTALLATION INSTRUCTIONS

1. Disconnect battery cables

2. Remove the plastic APPS cover.    Next remove the six, 10 mm headed bolts that hold the bellcrank assembly on. When   that is removed, you will see the sensor on the back. A T20 Torx is needed here.*Caution, these screws have loctite on them. So make sure that the bit is engaged fully into the screw head, so they do not strip, or you will need to use visegrips to remove them. NOTE: 2 new screws are provided. 

3. After the old sensor is removed, take the new sensor and look at the side that bolts to the bracket. In the center, you will see the slot that engages in the tang of the bellcrank shaft. Next, line up the slot with the tang and push the sensor onto the mounting surface. *If a sensor does not mate flat to the mounting surface, the slot is not engaged properly, try again.

4. When you are sure the tang is engaged properly, rotate the sensor clockwise, until the screw holes are aligned, and start the screws.  Just before the screws are tight, twist the sensor clockwise and tighten the screws.

5. Remount the bellcrank assembly to the bracket.

6.  Next procedure is setting the idle voltage, using a digital voltmeter, and turning                       the idle stop screw clockwise. *Caution, the screw has loctite on it from factory. You will need a T20 Torx bit with a ¼ inch ratchet to turn it. Make sure the bit is engaged fully into the head before attempting to turn. Be careful not to strip the torx head! *If needed, a propane torch, VERY CAREFULLY, can be used to heat the screw; this will soften the loctite and allow it to break free. Only heat it for a couple seconds at a time and attempt to turn clockwise. Next look on the back of the 6 pin electrical connector, it is numbered. With the paperclip provided insert it into the back of the connector PIN # 3 (Green wire). Or insert it into the back of the factory plug(light blue wire w/black tracer) just make sure its PIN #3. This will get hooked to the positive lead of the voltmeter. The ground lead can be hooked to the ground terminal of the battery. Turn your voltmeter to the low voltage DC scale. Make sure paperclip does not contact ground. Proceed to plug the sensor into the factory harness and then hook the batteries up. Turn the key to the ON position. Now read the voltmeter, it should read .580-.700.  Next turn the idle stop screw clockwise, NOTE you may turn for a little bit before the voltage actually rises. As soon as the voltage begins to rise, turn the screw backwards ½ turn and you are done with the idle screw.  

. To check the full throttle voltage, move lever by hand to full throttle. The voltage will be about 3.8V. Some voltmeters can vary a little so don’t be alarmed if reading are NOT to the exact tenth of a volt. 

7. Turn key off, disconnect voltmeter, and pull paperclip out of pin #3. Last procedure, turn key ON, press accelerator pedal slowly to the floor and then let up slowly. During this procedure the ECM  learns the new APPS voltage.

Most of that is also in the article database too.

Thanks I was mainly wanting to know if there was any thing out side the directions I needed to know, but I installed it today  it went smooth a couple tips tho use a quality t20 bit because I broke 2 cheap ones and its almost impossible to turn the idle adjustment with out heat and be sure to make some alligator clips for the meter  it a pain if not
