Navigating the complexities of vintage car diagnostics can be challenging, especially when dealing with early automotive computer systems. For owners of 1988 Chrysler vehicles, the DRB2 scan tool emerges as a key piece of equipment for understanding and troubleshooting their car’s onboard computer. But how effective is this tool, and what are your options when working with a classic Chrysler from this era?
In 1988, automotive computer technology was still in its nascent stages. Compared to today’s sophisticated systems, these early setups were quite primitive. Major manufacturers like Chrysler utilized their own unique systems and diagnostic procedures. For vehicles equipped with carbureted engines, the computer control systems were often basic, primarily managing fuel mixture through carburetor adjustments.

The real advancements in computer control came with the widespread adoption of fuel injection. Fuel injection allowed for much finer and more precise metering of fuel compared to carburetors. This leap in technology significantly improved engine performance and efficiency, and also made diagnostics more meaningful and effective.
While handheld scan tools like the DRB2 were available, the rapid pace of automotive technology meant they could become outdated relatively quickly. Even professional garages found their expensive, roll-away scan tools becoming less useful as newer vehicles adopted more advanced diagnostic systems requiring updated equipment.
For owners of 1988 Chrysler vehicles with carbureted engines, a pragmatic approach might involve simplifying the computer control system. Consider reverting to a more basic setup: a fixed distributor base timing with vacuum and centrifugal advance, paired with a non-computerized carburetor. Disconnecting the EGR valve and using a direct vacuum advance line could potentially improve engine performance and even fuel economy in city driving.
It’s important to remember that these early computer control systems were primarily designed for emissions compliance. They allowed manufacturers to lean out fuel mixtures to meet increasingly stringent emission regulations. This often led to the saying, “mileage may vary,” highlighting the compromises sometimes made in pursuit of emissions targets.
For diagnosing your 1988 Chrysler, understanding the limitations of the DRB2 scan tool and the nature of early computer systems is crucial. While the DRB2 can offer insights, sometimes a more hands-on, simplified approach to engine management can be more effective for these vintage vehicles.
