BDM pads or rainbow cables have been commonly used for full Read/Write operations on Denso units. However, users frequently encounter issues with these methods, often due to electromagnetic interference from subpar wires and excessively lengthy cables. Thankfully, there is a solution that has emerged after hours of troubleshooting.

The primary challenge lies in the electromagnetic interference affecting these low-quality wires. Moreover, the cables can sometimes be overly long, leading to operational hiccups. Denso units, being housed in aluminum holders, offer a potential solution as aluminum can function as a shield against interference. By connecting this aluminum holder to the common ground of programming tools such as KT200, TagFlash, and others, a robust solution emerges.

This technique guarantees a seamless reading or writing experience for any Denso unit, eliminating the occurrence of errors. It is advised to maintain a power supply of 14V for optimal performance. Additionally, to mitigate interference, a rainbow cable with a maximum length of 15cm is recommended.

Here is a list of the Denso units that can benefit from this method:
