Deleting the ABS (Anti-lock Braking System) in an E36 BMW, particularly OBD2 models, is a modification sometimes considered for track or race applications. However, simply removing the ABS pump without proper compensation can lead to serious braking issues. This article will explain why installing an adjustable proportioning valve is crucial when performing an E36 Obd2 Abs Delete, ensuring safe and balanced braking performance.
One common misconception is that removing the ABS pump is a straightforward process. While physically removing the unit might seem simple, it fundamentally alters your car’s braking system. The original ABS system incorporates a proportioning valve function, which dynamically adjusts brake pressure between the front and rear axles to prevent wheel lock-up. Without this crucial component, you risk creating a dangerous imbalance in your braking bias.
Removing the ABS without installing a proportioning valve often results in a fixed 50/50 braking bias, or something close to it. This is far from ideal, especially in a rear-wheel-drive car like the E36. In most driving and especially in performance braking scenarios, you need more braking force at the front wheels. A 50/50 split, or even a slightly rear-biased setup after ABS removal, will dramatically increase the likelihood of rear wheel lock-up, particularly under hard braking. Rear wheel lock-up can lead to spins and loss of control, especially at higher speeds or on track.
To correctly perform an E36 OBD2 ABS delete, you must install an adjustable proportioning valve. This valve replaces the proportioning function that was originally integrated into the ABS pump. By installing an adjustable valve in the brake line running to the rear wheels, you regain the ability to fine-tune the front-to-rear brake bias. This adjustment is essential to ensure that the front brakes engage effectively and do the majority of the stopping, while the rear brakes provide stability without locking up prematurely. Proper adjustment of the proportioning valve is crucial for optimizing braking performance and maintaining vehicle control.
Many E36 owners who consider ABS delete are focused on track performance and may question the effectiveness of the stock ABS system in such demanding conditions. The E36 ABS system, while functional for its time, is relatively basic compared to modern systems. Its intervention thresholds and responsiveness might not be perfectly optimized for aggressive track driving or cars with modified setups, tires, and brakes. Some drivers prefer the direct feel and control of a non-ABS system, believing they can better modulate braking at the edge of traction themselves. This is a valid point, particularly for experienced drivers in controlled track environments. However, even for track use, a properly balanced braking system with a proportioning valve is paramount for safety and performance after an ABS delete.
In conclusion, if you are considering an E36 OBD2 ABS delete, remember that it is not just about removing components. It’s about understanding the function of each part and compensating for its removal to maintain a safe and effective braking system. Installing an adjustable proportioning valve is not an optional step; it is a necessary component for a safe and properly functioning braking system after an E36 ABS delete. Ignoring this crucial step can lead to dangerous braking imbalances and significantly compromise vehicle control. Always consult with experienced professionals when modifying your vehicle’s braking system to ensure safety and optimal performance.
