launch smartlink C V4 vs smartlink C v2

1. Hardware Performance Upgrade

Connector Performance Leap: The connector’s CPU has been upgraded from a single-core to a dual-core processor, with the clock speed increased to 1.7 GHz. The RAM has been expanded from 256 MB to 1 GB, significantly accelerating computational response speed and enabling more efficient command execution. The CAN bus has been upgraded to 4 channels of CAN FD, delivering comprehensive improvements in communication bandwidth and transmission capacity to support diagnostic requirements for a wider range of newer vehicle models.

2. Diagnostic Functionality Upgrade

Graphical Diagnostic Display: Supports graphical visualization of special functions, topology maps, and data streams. Data trends are intuitively visible, enabling more precise and efficient fault localization and eliminating the need for cumbersome text-only interpretation.

High-Speed Scanning: Utilizes multi-channel synchronous scanning technology to process diagnostic tasks in parallel. Compared to traditional single-channel scanning, this significantly improves efficiency, delivering faster diagnostic speed and reducing repair time.

AI-Powered Fault Remediation: Visually displays fault points and provides targeted, highly feasible optimization solutions.

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...
