What is a JB4?

The JB4 is a plug & play tune available for turbocharged vehicles. The JB4 tuner installs between your car's sensors and its DME/ECU (computer) and manipulates vehicle performance through these connections making your vehicle much faster. While it's not the only tuning system that operates this way the JB4 separates itself from the competition with much more advanced connection points and processing, including CANbus, fuel & spark control, Bluetooth to your smartphone, and a variety of innovative and advanced features not possible with any other system. BMS regularly publishes free mapping and firmware updates adding performance and features as ongoing development allows. In addition, the JB4 system is not VIN-locked to your vehicle and can quickly be removed and swapped between cars or resold at a later time. Often imitated but never duplicated, the JB4 has been the gold standard in plug and play turbocharged performance tuning for over a decade. 

If your looking for N74 tuning for your 2016-2022 G12 BMW M760Li xDrive V12 the JB4 is a perfect BMW V12 engine tune.

Good read
"I know you were once an child with dreams but I once your child with my own dreams." Is a quote that relates to this book.While it needs to be edited more and some mistakes fixed, this has allowed me and many others to understand our parents better and work towards fixing what they have done or even what they failed to do.

Guidelines for Self-awareness and change
This book’s focus, to me, was about self-awareness: 1 to what degree were my parents emotionally immature and what impact, if any, did this impact me?; 2. To what degree have I grown and developed in emotional intelligence/nurturing resilience?; and what impact did my behaviors have on my children’s development? An interesting exercise

A Practical Guide to Breaking the Cycle of Emotional Immaturity
“The Legacy of Emotionally Immature Parents: Gain Insights and Solutions Across the Generations to Navigate Child-Rearing Challenges, Build Healthy Relationships, and Grow Emotionally” by Mike Palm is the practical guide for parents who couldn’t fully meet emotional needs, and couldn’t give what they didn’t have and the adults still carrying the impact. The book is quite well structured. For example, Chapters 1–2 define emotional immaturity, trace its roots and explore how it shows up in family dynamics. Chapter 3 focuses on breaking the cycle - identifying patterns, using boundaries, mindfulness, and behavioral change tools. Chapter 5 is on self-care - prioritizing it without guilt, designing routines, balancing family obligations, and practicing emotional detachment. Chapter 7 tackles forgiveness and building a legacy of emotional maturity. Overall, this is a practical guide for anyone who grew up feeling emotionally unseen and wants to parent differently. Highly recommended for parents who recognize emotional immaturity in their upbringing and want to stop the cycle, or anyone wanting to build healthier relationships with family members who may still carry those patterns.

Emotional neglect—more than obvious abuse—is the real wound
By Maria Castillo, LMFT “Family and Marriage Counselor,” Academic / Research-Based Review of Healing the Legacy of Emotionally Immature Parents Healing the Legacy of Emotionally Immature Parents is a well-constructed and clinically grounded exploration of the long-term impact of emotional immaturity within family systems. As a family and marriage counselor, I find this book to be an invaluable resource for understanding and treating intergenerational patterns of emotional neglect, insecure attachment, and maladaptive coping strategies. The author integrates core principles from developmental psychology, attachment theory, and systems theory to explain how emotionally immature parenting shapes the child’s internal working models and self-perception. The book clearly outlines how children raised in emotionally dysregulated or self-focused environments often develop hypervigilance, people-pleasing tendencies, emotional suppression, or role reversal—phenomena well documented in research on childhood emotional neglect and parentification. One of the book’s strengths is its ability to translate complex psychological mechanisms into accessible language without sacrificing clinical integrity. The descriptions of emotionally immature parent subtypes parallel established constructs in family systems literature, including emotional cutoff, enmeshment, and boundary diffusion. The author also highlights how these patterns tend to be transmitted across generations unless actively disrupted through insight, boundary formation, and emotional differentiation. From a therapeutic standpoint, the framework aligns well with evidence-based approaches such as attachment-focused therapy, trauma-informed care, and internal family systems work. The book offers practical tools that support emotional regulation, cognitive reframing, and boundary setting—interventions consistently supported by current research in relational and developmental trauma. Overall, *Healing the Legacy of Emotionally Immature Parents* is a robust and clinically relevant text. It serves not only as a validating resource for clients but also as a practical companion for clinicians working with adults who struggle with unresolved childhood emotional injury. Its emphasis on differentiation, self-leadership, and intergenerational healing makes it a meaningful contribution to the literature on family therapy and adult attachment.
