Launch X431 V+ or PIWIS-III for Porsche Diagnosis?

I have the Launch X431 V+ Pros Mini which I purchased new from obdii365 for $1079. I also have a PIWIS III clone V38.90 that i purchased from another website for $1429. I purchased the Launch X431 V+ with the intent of using it to flash a used control module for my car. When I discovered that the Launch X431 V+ could not do that I purchased a PIWIS III clone with the intention of selling the Launch X431 V+ but I have not got around to selling it yet because it is so much easier to use then the PIWIS III.Here is what I have done so far with each one. Launch X431 V+ : Cleared all the fault codes stored in the car. Activated the Aux setting in PCM (PCM/CDR) I had to add an aux cable to the PCM to make use of this one. Changed the number of flashes for one touch turn signal from 3 to 5 (Front-end Electronics) Activated Comfort entry windows up/down via keyfob (Front-end Electronics) Changed the speed when the doors auto lock, 3 mph to 20 mph (Front-end electronics) Changed the speed when...
