This unique handbook assumes no starting knowledge of car electrical and electronics systems. It begins with simple circuits and finishes with complex electronic systems that include engine management, transmission control and stability control systems.
If you want to diagnose a simple alternator charging or headlight problem, this book is for you. But if you also want to fix complex electronic systems using On-Board Diagnostics, a multimeter or oscilloscope, this book also shows you how to do that.
Is it best to use a series or parallel circuit when adding a horn? How do you use a multimeter to check a coolant temperature sensor against its specs? How can you add an electronic timer that will keep your headlights on as you walk to your door? When should you buy an oscilloscope - and how complex an instrument do you really need?
The author has been writing about car electronic systems for over 25 years. He is also an experienced and proficient car modifier who has performed numerous electronic modifications and upgrades to his own cars, including world-first modifications.
If you want a practical, hands-on book that demystifies and explains car electrical and electronic systems, this is the book for you.

Want to upgrade/update your cars electronic systems, but don't know how? Here's the solution!
Cars of the 1990s and 2000s are from a golden era - they've got sufficient electronic systems to achieve great outcomes, but they're not so complex that they're impossible to modify. The missing link, until now, has been a hands-on manual on how to achieve those results. Well, here it is!
This book covers everything from cheap modifications that allow you to adjust engine fuelling and ignition timing, to modifying car systems like power steering and even stability control. Easy upgrades to lighting, sound systems and the dashboard - right through to fitting and tuning programmable engine management. Photos and circuit diagrams guide you each step of the way.
All the car modifications are practical, and have been tried and tested by the author. From a 660cc turbo front-wheel drive screaming to 8500rpm on standard engine management but with big injectors... to a DOHC V8 rear-wheel drive with modified traction control... to a twin-turbo all-wheel drive with a custom torque split controller. Even modifying the re-gen braking on a hybrid!
This book is essential reading for anyone who wants to exploit the true electronic potential of their 1990s-2000s cars.
