knight Posted July 4, 2011 Author Share Posted July 4, 2011 Some are chippable, some arnt. Mate has one in his Teg obd2 and not chippable. Easiest way to check is open it up and see if there's space for an EEPROM chip.is it usdm or jdm one mate:?: Link to comment Share on other sites More sharing options...

johngreen537 Posted July 5, 2011 Share Posted July 5, 2011 Yup, you need the one from the Integra GSR / SiR, USDM one! Link to comment Share on other sites More sharing options...

noodels Posted July 7, 2011 Share Posted July 7, 2011 and i want one!!! soIt is roumoured that the MB6 was intended to use the P72 ecu found in older Honda's, as it is labeled with P72 in the engine bay. However, even though the car got given a mildly tuned P9K it is not impossible to run on a more aggresive JDM P72 (003 AS) used in the Integra Si (92-95). The best bit is that the P72 is chipable, therefore it can be re-mapped to extract more power from other mods you may have done to your car and it also allows you to disable the 115mph speed limiterThe standard ecu (P9K) is of the OBD2 type but oddly it still has OBD1 style plugs. So, if you are not into using piggyback ecu's then a great alternative is to replace the P9K for a JDM P72. A slight modification to the A plug is required to fit in the ECU. This is done by simply shaving two ribs from the 'A' plug (this will not affect reverting back to the original ecuOf course, simply replacing the ecu is not enough to make it work and modifications to the main board is required in order to restore the VTEC changeover and getting the IAB's (dual butterflies) to work properly. But before you start, it might be a good idea to check what codes are being thrown - You should only get codes 20, 22 & 23 which code 22 will be dealt with by bridging the VTEC Solenoid Valve to the VTEC Oil Pressure Switch (as shown below), codes 20 & 23 can be dealt during the chipping process with a rom editor. To get the VTEC to engage bridge pins A4 & D6 and for the IAB's you will need to bridge pins A17 & A19... well thats My thought on the issue jdm it is my nose is getting bigger http://cars.homenetcs.co.uk/honda-civic ... ns-ecu.htm Link to comment Share on other sites More sharing options...
