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.

Tools

the

the
• Thinner or acetone to wash the protective varnish from the Board
the
• Powerful soldering iron
the
• Flux, better not active
the
• Solder (can be tubular with a flux)
the
• a Syringe for sucking solder — suction

the

the
• Cot DIP-28 wide
the
• Jumper J1 (reverse side)
the
• Jumper J4 (front side) remove to enable DATALOG

the
• to Remove the RP17 resistor

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.
