Timing 5.7 vortec

[kponch]

Hi, I like to down load an APP that I can use to adjust and verify my distributer timing on 5.7 vortec. I also like to do crankshaft sensor relearn. I know nothing about what APPs to use/download. And I surely do not know how to use the APP. I have read some really good forums on this site about 5.7 vortec timing and crank sensor relearn. Could someone please take the time. To tell me what APP can do both. And how do I use the APP to do it. That would be so great. I have other vehicles to do crankshaft sensor relearn. Thank you
