Notable overlap: Both can read/write 93Cx6 and 24Cxx EEPROMs. Both fail on very new (2019+) encrypted modules.
IProg+:
When you verify these tools by cracking open the casing (as many forum users have done), the differences are stark. carprog vs iprog verified
CarProg Hardware: Older CarProg clones were notorious for using cheap voltage regulators that could fry if you looked at them wrong. Modern clones (post-2017) have improved, often featuring the PIC18F4550 MCU and better voltage protection. Notable overlap : Both can read/write 93Cx6 and
iProg Hardware: The iProg is built differently. Inside, you typically find a better-organized PCB with a focus on signal integrity. IProg+:
Winner: iProg+. For pure hardware capability and safety for sensitive components, the iProg architecture is simply newer and better designed.
Let's walk through two common jobs.
