DIY Ecu chipping (p28/p72)

[1NonlyAccord]

This is a DIY Ecu chipping guide, if you have the skills,patients or just like doing things yourself like i do. this is a standard guide for the P28 ecu, other ECUs such as the P72 will not require the resistor included in the kit.


Required tools:

Moates Honda ECU Chipping kit
Soldering iron(cheap radioshack iron will work)
De-soldering iron (radioshack model: 64-2060)
wire cutters
Thin Rosin core solder
philips screwdriver
Optional tools:

cheap carborator cleaner**DO NOT USE B12-Chemtool**
electrical tape
old toothbrush
lets get chipping
1> Remove both top and bottom covers from the ECU.
2> Remove all screws holding the circuit bored in place, and loosen the screws holding the main voltage regulator to the case.

3> Remove the circuit bored, and use electrical tape to cover the small hole on the barometric pressure sensor.

4>Spray the lower half of the ECU with the Carb Cleaner and use the toothbrush to scrub the plastic coating off. This usually takes about three iterations before it is clean. Clean both the front and the back. Also clean the area around J12.
