Before you turn a single bolt on an F8-powered 626, MX-6, or Bongo van, invest the time to locate a genuine PDF. Save it to your phone, tablet, and a cloud backup. Your engine – and your sanity – will thank you when the job goes smoothly, and the engine fires up with quiet, smooth reliability for another 100,000 miles. If you cannot locate a free PDF, consider purchasing a used original manual from a Mazda collector. For a one-time rebuild, the cost is trivial compared to a blown head gasket from incorrect torque.
Introduction: The Overlooked Workhorse The Mazda F8 engine is a often-overlooked yet highly durable powerplant from Mazda’s legendary F-family of inline-four engines. Produced throughout the late 1980s and 1990s, the 1.8-liter (actually 1789 cc) F8 served as the smaller-displacement sibling to the famous 2.0-liter FE and 2.2-liter F2 engines. While it lacks the performance pedigree of the turbocharged F2T, the F8 is renowned for its reliability, fuel efficiency, and smooth power delivery in economy-focused sedans, hatchbacks, and vans.

Note: the Vcc setting jumper only has effect when you are using AC adaptor as power source. For the USB power only 5V Vcc is available. For the PCB5.5C, set DIP steps: 1. press DIP Set button twice to check current DIP bit position. Then set it again for ON or OFF. 2. press DIP Bit shift button to shift the DIP bit position to where need to set. And then press DIP Set button twice to check current DIP bit position. Then set it again for ON or OFF. 3. Repeat those steps till all DIP bit ae set same as software indicated. For PCB5.5C voltage and Special chip selection: 1. Put back the safety jumper. 2. Press the voltage button and hold for 1 second, the voltage LED should move to next. Repeat till desired voltage LED light up. 3. Press the chip selection button and hold for 1 second, the chip LED should move to next. Repeat till desired LED light up. 4. Remove the safety jumper to lock the selected voltage and chip selection  DIP Switch (PCB3.5, PCB5.0)
