For automotive enthusiasts and professional mechanics alike, having a reliable scan tool is indispensable. Recently, I had the opportunity to put the Blue Point Eecr 3a Scan Tool to the test, specifically focusing on its capabilities with both older OBD1 and modern OBD2 systems. After working with it, particularly getting the live data to display smoothly, I’ve gathered some key insights worth sharing, especially if you’re in the market for a versatile diagnostic tool.
OBD2 Scanning: A Market Overview
When it comes to generic OBD2 scanners, the market is saturated with options. You can find basic scanners, many offering live data, for as little as $35. These budget-friendly tools often meet the needs of users looking for quick fault code reads and basic diagnostics on newer vehicles.
A popular trend is the rise of Bluetooth or Wi-Fi ELM327 OBD2 adapters. Paired with a smartphone or tablet and OBD2 apps like OBD Fusion® (available for both iOS and Android), these setups offer a portable and cost-effective way to monitor vehicle data on the go. These apps vary in sophistication, with some offering advanced features and data logging capabilities.
Why Choose the Blue Point Microscan III? Beyond Basic OBD2
While these modern, app-based OBD2 solutions are compelling, my need for the Blue Point Microscan III stemmed from a different requirement: OBD1 support. I purchased the Microscan III as a replacement for my aging Innova OBD1/OBD2 scanner, which served me well for years but had finally given out. The Microscan III, while potentially a used tool now, addresses a crucial need for those working with older vehicles.
I personally work on a couple of OBD1 Ford vehicles from the late 80s and early 90s, and assist a friend with a 1992 OBD1 Jeep Cherokee Laredo. Furthermore, classic Jeep enthusiasts know that Renix-era Jeeps (1986-1990) utilize a unique Renix/AMC computer system that, remarkably, can provide live data readouts using scanners like the Snap-On MT2500.
My primary goal in testing the Blue Point Microscan III was to evaluate its OBD1 functionality and see if it could match the performance of the industry-standard Snap-On MT2500. The OBD1 cable for the Microscan III, when purchased separately, can cost around $40, while complete Snap-On OBD1 connector sets can range from $150 to over $350 new. While more affordable OBD1 connectors from other manufacturers exist, compatibility with Snap-On tools, including the Microscan III, is not guaranteed and could potentially damage the scanner. I have been sourcing original Snap-On OBD1 adapters to use with both the MT2500 and now the Microscan III to ensure safe and reliable diagnostics.
OBD1 Functionality: A Key Differentiator
The inclusion of robust OBD1 functionality was a major factor in my decision to purchase the Blue Point Microscan III. For those regularly working on pre-1996 vehicles, this capability is not just a convenience, but often a necessity. Modern, low-cost OBD2 scanners and ELM327 adapters simply won’t communicate with these older systems.
Stepping Up to Professional-Grade Diagnostics: DRB-3 and Beyond
For comprehensive diagnostics on Chrysler vehicles, especially those requiring advanced functions like PCM reprogramming, the DRB-3 handheld scanner has long been the industry benchmark. These professional-grade tools, often costing around $6,000 new (or ~$3,000 used), offer extensive capabilities far beyond generic OBD2 scanners. While the Blue Point Microscan III doesn’t reach the level of a DRB-3, it aims to bridge the gap, offering a more versatile solution than basic OBD2 tools, particularly with its OBD1 support.
ShopStream Connect and Data Analysis: Initial Impressions
The Blue Point Microscan III also boasts compatibility with ShopStream Connect, software advertised to provide advanced data analysis with high-resolution graphs and detailed reports. However, my initial experience with ShopStream Connect has been limited to generating small, low-resolution BMP files. Further exploration is needed to fully evaluate the software’s capabilities and whether it lives up to its advertised potential.
Blue Point EECR 3A: Is It Worth the Investment?
The value proposition of the Blue Point EECR 3A scan tool depends heavily on your specific needs. New, it may be a significant investment. However, used units can be found for around $110 to $150, making it a more attractive option, especially for those needing OBD1 capabilities. For users primarily working on OBD2 vehicles, cheaper and more modern solutions might suffice. But for mechanics and enthusiasts who regularly encounter OBD1 systems, the Blue Point Microscan III offers a valuable and capable tool for comprehensive vehicle diagnostics.
