After recent discussions surrounding OBD2 chip tuners, we decided to investigate. We researched, asked questions, and gathered enough information to test an OBD2 chip ourselves. We understand the skepticism surrounding these devices – are they just “resistor scam chips” or can they genuinely improve performance? Several companies now offer OBD2 chips claiming to adjust the air/fuel mixture and advance ignition timing. Let’s dive into a review of two popular options.
Volo VP15 and Sawyer Tuning ST8PRO: A Comparative Overview
Two chips frequently mentioned are the Volo VP15 and the Sawyer Tuning ST8PRO. Both promise performance enhancements via OBD2 connection.
The Volo VP15 boasts some customization options, allowing users to fine-tune the performance adjustments. You can find more details about this chip on the manufacturer’s website: https://volo-performance-inc.myshopify.com/products/675g97. Performance Chip Reviews also offers a detailed analysis: http://www.performancechipreviews.com/vp15-volo-chip/.
The Sawyer Tuning ST8PRO, while lacking the customization of the Volo VP15, promises similar performance gains. The manufacturer claims a lifetime warranty and money-back guarantee: http://www.sawyertuning.com/product/best-st8pro-stage-3-obd-gas-diesel-performance-chip-programmer-30hp/. A comprehensive review is also available on Performance Chip Reviews: http://www.performancechipreviews.com/st8pro-performance-chip/.
Real-World Testing of the ST8PRO OBD2 Chip
We opted to test the ST8PRO. The manufacturer assured us of compatibility with a 2014 Mitsubishi Mirage and guaranteed no adverse effects on the engine. At $130, the potential fuel economy improvements alone could offer a return on investment within a year.
The results were surprising. Throttle response felt quicker and smoother, with a noticeable increase in power. Low-end torque improved significantly, and the engine revved more freely. Acceleration felt enhanced, and high-speed cruising became more effortless.
Initial fuel economy tests showed a promising increase of over 1 MPG with aggressive driving. After resetting the chip and driving over 300 miles, the improvement increased to over 2 MPG. Long-term testing will reveal whether these gains are sustained.
OBD2 Chip Tuning: A Cost-Effective Performance Solution?
While this review lacks dyno runs and technical graphs, our real-world experience with the ST8PRO indicates a tangible performance improvement. The fuel economy gains alone could justify the cost. While a custom re-flash might offer superior results, OBD2 chip tuning presents a cost-effective alternative, especially while waiting for more comprehensive tuning solutions. For discussions on further tuning options, you can refer to this forum thread: https://mirageforum.com/forum/showthread.php/5647-6th-Gen-Mirage-Tuner-Power-Programmer-ECU-Piggyback-Where-are-we-now. Our initial experience suggests that OBD2 chip tuning can offer a noticeable performance boost and potential fuel savings, making it a worthy consideration for those seeking affordable enhancements.
