The ChipMax (manufactured by EE Tools) is an entry-level professional universal device programmer. Originally released with a parallel port interface, newer models utilize USB connectivity (such as the ChipMax2).

It is a popular choice for burning EPROMs (like the 27C256) and EEPROMs (like the 28C256) used in OBD0 and OBD1 Honda ECUs.

Key Features#

• Universal Device Support: Features a high-quality 40-pin Zero Insertion Force (ZIF) socket. It supports a wide range of devices including EPROMs, EEPROMs, Flash memory, and microcontrollers.
• Reliable Hardware Timings: Unlike low-cost generic burners (such as the Willem or DIY "Ghetto Burner" designs), the ChipMax features dedicated internal controllers that handle precise programming voltages and timing cycles, preventing verification failures and damaged chips.
• Software & Support: EE Tools maintains regular software updates for device support. Historically, their technical support has been known to write custom device profiles upon request.

Comparison & Usage#

Compared to hobbyist-grade burners, the ChipMax is highly stable, making it a preferred option for tuners who frequently read and write ROMs. The control software allows for quick checksum verification, blank checks, and buffer editing prior to writing.
