For automotive technicians and DIY enthusiasts alike, having a reliable scan tool is indispensable for diagnosing vehicle issues efficiently. While the market is saturated with generic OBD2 scanners, tools that bridge the gap between older OBD1 systems and modern OBD2 are highly sought after. The Blue-Point Microscan III aims to be such a versatile tool. After getting my hands on one, I’ve been putting it to the test, and here are my initial impressions.
Generic OBD2 scanners are readily available, often for very affordable prices, sometimes under $35.00. Many of these offer live data streaming, a crucial feature for real-time diagnostics. The rise of smartphone-based OBD2 solutions, utilizing Bluetooth or Wi-Fi ELM327 modules with Android or iOS apps like OBD Fusion®, presents another accessible avenue for vehicle monitoring. These apps can transform your phone or tablet into a diagnostic dashboard, offering convenience and portability.
OBD Fusion stands out as a top-rated OBD2 diagnostic app for iOS devices, boasting extensive features and even CarPlay integration for seamless in-car use.
However, my need for the Blue-Point Microscan III stemmed from a desire to replace my aging Innova OBD1/OBD2 scanner, which I had purchased for around $200 years ago. My vehicle fleet includes a couple of OBD1 Ford vehicles from 1988 and 1992, and I frequently assist a friend with a 1992 OBD1 Jeep Cherokee Laredo. Furthermore, classic Renix Jeeps, produced between 1986 and 1990, utilize a unique Renix computer system that can provide live data readouts with professional-grade scanners like the Snap-On MT2500.
My primary objective in acquiring the Blue-Point Microscan III was to evaluate its OBD1 capabilities and determine if it could match or surpass the performance of the trusted Snap-On MT2500. The OBD1 functionality was a key deciding factor in my purchase. The necessary OBD1 cable, purchased separately, adds around $40 to the cost. Snap-On OBD1 connector sets are notoriously expensive when new, ranging from $150 to over $350, although used sets can sometimes be found online for around $80. While there are OBD1 connectors from other manufacturers, compatibility with Snap-On or Blue-Point scanners is uncertain, with warnings that using incorrect adapters could potentially damage the scanner. I’ve managed to acquire a few genuine Snap-On OBD1 adapters that are compatible with both the MT2500 and, crucially, the Microscan III.
For comprehensive diagnostics on Chrysler vehicles, especially those requiring deeper access and PCM reprogramming, specialized tools like the DRB-3 handheld scanner are often necessary, albeit at a significant cost of around $6,000 new. Used DRB-3 scanners can be found for around $3,000 or less, depending on included accessories. Other manufacturers also produce scanners with DRB-3 compatibility.
Regarding the ShopStream Connect software associated with the Blue-Point Microscan III, online promotional materials showcase advanced analysis features with high-resolution graphs and detailed data interpretation. However, my initial experience has been limited to generating small, low-resolution BMP files. This discrepancy raises questions about the true value proposition of the Blue-Point Microscan III, especially considering its new price. Used units are available in the $110 to $150 range, which might represent a more reasonable investment depending on the features and functionality delivered. Further testing and exploration are needed to fully assess the capabilities of this Blue Point Mini Scan Tool and its place in the automotive diagnostic landscape.
