The Dralyn OBD2 Chip Tuning Box is a small plug-and-play module that connects to a car's 16-pin OBD2 port. Dralyn claims it raises performance by 15% and cuts fuel consumption by 20% by adjusting boost pressure, injection quantity, injection time and pressure after reading ECU data. It is aimed at drivers of 1996-and-later cars who want a cheap, removable tweak rather than a real ECU remap. Independent tuners and mechanics are skeptical of such boxes: a device that only reads and writes generic OBD2 data cannot safely rewrite fuel and boost maps on most modern engines, and gains that large are not credible. Treat it as a low-cost experiment, not a substitute for a proper tune.

The Dralyn OBD2 Chip Tuning Box is a plug-and-play device. It connects to the 16-pin OBD2 port of vehicles manufactured after 1996.
Once connected, it receives data from the vehicle's control unit (ECU). It then adjusts charge pressure, quantity, injection time and pressure. Performance increases by 15% and fuel consumption drops by 20%.
It does not damage the ECU or change the vehicle's factory settings. To return to the factory settings, disconnect it from the OBD2 port.
