You don't need a code reader for the '95 Civic. There is a service check
connector behind the carpet under the glove box (above the ECU) The
service check connector is 2-pin. There is a 3 pin data-link connector
in the same harness, and they are both taped to a wire harness above the
ECU. Pull both connectors down and short the two pins of the 2-pin
connector with a paper clip or a piece of wire, then turn on the
ignition. The error codes will be flashed on the MIL in the instrument
cluster. Long flashes are the 10's, short flasher are the 1's (4 long
flashes and 2 short flashes means 42). Multiple different codes may be
flashed after another. After all codes are flashed out, it starts over
again with the first error code.
When you have read the codes, turn off the ignition and remove the paper
clip.

This project is build around one of new Microchip PIC18F2455/2550 8-bit microprocessor with USB support. ThePIC18F2455 USB core is V1.1 and V2.0 compliant and operates at 1.5 Mb/sec and 12Mb/sec speeds respectively. The microprocessor has 2048 bytes of RAM and 24K of Flash program memory, which is plenty for implementing the OBD2 controller functionality using high-level C programming language.

연비 10K, 약 30% 증가~~
따지고 보면 운전 습관만 교정하는것 뿐인데, 연비에는 많은 차이가 있다는것을 알수 있다.
테스트 구간은 아침 출퇴근 구간으로 고속 정속이 많은 구간 이긴하다.
출 퇴근 구간에서는 8.3 정도 나오고(15일 평균). 물론 고속도로 주행시에는 9.5~10 정도가 나온다.
www.fueleconomy.gov에서의 기준 연비 15,18
MPG 를 참조해 보면
6.1~7.4 KPL 수준에서 평균 서울 시내 주행 8.3~9.5 KPL 으로 증가했다. 흠 뭐 이정도면
운전 습관을 고쳐볼만 하다.
주말때 시간 날때마다 조금씩 작업하던건데, 4달이나 작업한듯 싶다. 역시 게으름이....
Application 은 개발 환경은
다음과 같다.
- Application : VB 6.0
- NIDAQ Interface NI6008)
- Mesurement Studio 6.0 VB Graph
Component
어쨌든 연비 개선 프로젝트는 종료~ !!
