During programming, selected bits can be set to 0, but it’s not possible to set them back to 1 without erasing the entire chip again. Once he has completed figuring out the programming table of the EPROM, he plans to do some testing with to possible smooth out the rev limited.Īn interesting aspect of EPROMs is that they are erased using UV light, which sets all the memory bits to 1. One of the previous owners of ’s Civic made some unknown tuning changes, so he is in the process of looking at the dumped data to see what was changed. Rinse and repeat for each of the 256 memory addresses on the Microchip 27C256 EPROM. The memory address is selected by setting each of the 15 address pins high or low, and then reading the status of the 8 data pins to extract one byte of data. After realizing that could only clone the contents, but not view or modify it, he started looking at ways to do that.ĮPROMS are programmed using higher voltage (12.5 V – 25 V) but to read them 5 V is used. This was done with an old Advantest R4945A EPROM programmer, which supposedly also used to clone Famicom cartridges back in the day. At Schnitz Racing, we have the experience, knowledge, and tools to maximize your motorcycle's performance, ensuring you get the most out of your riding experience.Owns a pair of early 1990’s Honda’s with custom tuning on their stock ECUs, and after having to get the ECU repaired on his ’93 civic, he found himself going down the rabbit hole of Honda ECU EPROM chips.ĭuring the repair process, the tuning shop owner, or as refers to him, made a backup of the custom tuning to another EPROM chip. Whether you're a casual rider or a seasoned racer, our ECU flash service will deliver noticeable improvements in power, responsiveness, and overall rideability. We can also disable unnecessary restrictions and features, such as top speed limiters and exhaust servo controls.īut why do you need an ECU flash? Simply put, an ECU flash by Schnitz Racing will ensure your motorcycle performs at its best, matching your unique riding style and preferences. This includes optimizing fuel maps for better throttle response and smoother power delivery, adjusting ignition timing for improved combustion efficiency, and modifying electronic throttle controls for more accurate and responsive throttle input.
