And so, You dont find your firmware the repository PGMFI.org. If so, then take a look at your Board control unit P28 (or similar P08, P72, P06 OBD1). Under the area where you soldered an additional chip, a connector CN2, pins consists of 5-points (calculated from left to right), this connector needs to pass information from the ECU to the ECU OKI 66207. Signal type TTL. \nSimple TTL-RS232 Converter is in a separate article, and only need the channel reading on the ECU itself the ECU nothing is sent. The description for each contact I quote below, after using the app and reader is TTL you should be okay. Unsoldering the connector easily, do not forget that you first need to remove the varnish that protects the charge ECU P28 (or similar P08, P72, P06) solvent paints, for example .

The

Pinout of DataLog (Datalog Pinouts)

Below is the Pinout of CN2 connector OBD1 P28, data transmission is in the mode of half-duplex (half-duplex), for full duplex you need to eat J12, is located on the left part of the Board between white and black, vertical, circuits.

the
    the
  • pin 1 — GND ground
  • the
  • pin 2 — the RX to send data from PC to ECU
  • the
  • 3 pin — the +5v power bus
  • the
  • pin 4 — TX to receive data from the ECU to the computer
  • the
  • 5 contact — NC not connected to anything
the

the read Program firmware

Before you start working on reading flash you need to program the chip, more than and how to flash w27c512 is in the article. You record special program romreader_66207, which pumps out firmware original firmware Honda Civic ECU via RS232 to the computer.

The

Preparation for reading original firmware P28 (or similar P08, P72, P06)

If you havent installed the chips and then move up the article and follow the necessary instructions. If you are all done, check everything again before work.

the
    the
  • In the crib the inserted chip 74HC37C, I use MM\MC74HC373N
  • an
  • 27C512 Chip series use WinBond W27C512-45Z recorded with the program romreader66207
  • the
  • Computer, or an adapter for a COM port
  • the
  • is There a Converter TTL-RS232
  • the
  • Has a DC supply of 12 volts, capable of giving 120 mumper (0.1 Amps)
The

Read firmware P28 (or similar P08, P72, P06) OBD1

the
    the
  • turn Off the ECU
  • the
  • Install a 74HC373 chip, the label on the left
  • the
  • Select the 27C512 chip, prying off the first leg of the chip, so that it does not touch the cot, the label on the left
  • the
  • 16 foot chip OKI 66207, connect the wire with 1 leg of the chip 27C512, this leg is responsible for food
  • the
  • 19 leg of the chip OKI 66207, connect wire 27 foot chip OKI 66207, it turns out this loop
  • the
  • Jumper that you have installed on J1 need to be replaced with a resistor 1 kOhm (1000 Ohms)
  • the
  • If the 27C512 chip inserted in his crib, and the DataLog wire from TTL-RS232 connected to the computer, run the downloader program
  • the
  • On the computer screen a window will appear with the address. If the address is not equal to 0000, press the RESET key
  • the
  • Turn on Your ECU, connect the power
  • the
  • after a few seconds, or immediately counter will start to increase
  • the
  • in a minute the meter should show 8001, 8002 this is the error, repeat
  • the
  • You can Now save the original firmware the SAVE button

After that, You can now take the new chip 29C256. To modify the firmware with the help of a program, which I will discuss in the article, and flash parallel programmer. Good luck!

The

The Application

Applications that I added are property pgmfi.org, Im just another who has collected all into a single, translated, repeated, and passed the knowledge to You in Russian. So, say thanks to the guys from PGMFI.org.

the \nThe

Plug-in ECU Honda OBD1 computer. DataLog.

First you need an adapter to TTL Level. It is usually called USB-TTL USB RS232 TTL USB UART. The main thing was the interface to connect to your computer (usb or com port) and the second word TTL. Further, according to the diagram above (2nd paragraph to read in full) connect the DataLog, programs such as Crome, HondaLogger, ECUControl you will be able to watch the car. Dont forget to change the baud rate on 38400 bits. Through CROME you must turn off the processing of the checksum (Plugins-Enhancements-Remove Checksum Routine) and to include in the firmware OBD1 DataLog mode(Plugins-Enhancements-Quick Datalogger +RTP). Dont forget to sew the new firmware. In the basic firmware, no DataLog.
