Im trying to find a chart that lists all the pin outputs relevant to a Hondata prepared P28 ecu equiped with S300 & boost control. :?:
This isnt comprehensive but id like to know the pins used for...
+hi/lo boost funtionality
+PLX M300 wideband installation
+traction control/launch control functionality?
+any other relevant pin-outputs/inputs used with the P28 & S300.
This is for a EK9 that will be using an OBD2->1 conversion harness.
Thanks in advance

Ok I have a couple of other questions for you; the reference section was a great help...
Ive modified my OBD2a->OBD1 adaptor harness with bullet-connectors for inputs/outputs on the ECU side.
Im going to be using the PLX's white wide-band signal wire to the ECU D10-ELD.
1
There is a note in the help file saying that somtimes certain ELD resisters must be removed before this pinout can be used. I bought my P28 ecu directly through hondata and it was prepared for boost control by hondata.
....WILL I NEED TO REMOVE ANY RESISTORS??
2
Also I want to use B5-ACS switch input to switch between high and low boost... Do I need to manually rewire the switch by removing all the heater controls and opening it up OR CAN I... use the 'INVERT-INPUT' option to make the factory wiring function without modification to the switch's wiring?
3
I extended both the grey narrowband signal wire to the engine harness clips white O2 signal wire whilst also making an adapter with a 1watt 1k resister between the two black O2 heater wires. I also extended the white wideband wignal to D10-ELD. I perfectly soldered and heatshrunk the joints but would like to know... will this affect accuracy after voltage correction in hondata
4
PLX Devices reccomends connecting the M300 to the ECUs power and ground whilst also using two noise filtering capaciters.
I intend to used switched +12v from the under dash ingnition feed with a local ground. a). Do I need to use power at or near the ecu or can Hondatas vltage correction chart be used to correct any innacuracy? b). Does hondata advise the fitting of these capacitors??
Cheers

As the instructions state, "you may need to remove the resistors".
The input can be wired to any switch you want to use, You will have to determine how a switch works to know how to connect and set everything.
Extending the wires should be fine as long as there is not interference.
THe capacitors are not needed. You should use the switched 12 volt source on the under dash fusebox. and a good chassis ground like our instructions say.
