JDM! So somehow you have a brain ECU P08, P30 or better (it has an knock sensor), so there are more options P70, P71, and so on. Often they are called — ECU small case JDM OBD1. They differ in that most components are SMD components, so that due to the miniaturization of the housing can be reduced. Processors on these boards were raised or OKI M66207, or its equivalent, of the company STMicroelectronics STK 66207, but in the PLCC-84 (QFJ).

Why chipovat

I Think if you got a OBD1 ECU brain, it means that you have more or less understand what you need. Well if it doesnt go over the main features. Almost all OBD1 brains are optional internal memory type 27C256, so it is possible to change the firmware. Specifically:

the
    the
  • to Install almost any engine Honda 92-2001 year, changing the firmware without changing the electrics and wiring
  • the
  • to move the cutoff point the RPM
  • the
  • to Shift the cutoff point for speed
  • the
  • to move the VTEC point
  • the
  • to Adjust the ignition map
  • the
  • to Adjust the map fuel injection
  • the
  • And more...

Well, if you dont want to use a ready firmware you will be able to rebuild the machine by installing the emulator memory Hondata or SofRom or similar.

Procedure soldering

If you have experience soldering then just follow the pictures and place the items in their places, only after installing the J1 jumper — the CPU will only work with external memory. So look for chip and firmware for your spec.
If no experience, open brain. Looking at pictures of fill the working area for a couple of minutes with solvent or acetone, dry dry and repeat on the reverse side of the Board. Pour cost is entirely pointless, and mechanically wiping the Board may result in damage to the tracks. But to walk carefully after soldering, alcohol (pure) will not be superfluous.
Further, all places under the honourable, that is, holes for installation \"filled\" with solder. Grease the flux, warm, and either suck the liquid solder with a special syringe or a bundle of wire dipped in flux ( but gently). If you use a DataLog, do not forget remove the jumper J4 on the back side of the Board.
