MS2-Extra Daihatsu 3,4cyl Manual

MS2-Extra Daihatsu 3,4cyl Manual

Only for use with the MS2-Extra code (HC9S12C64 based microprocessor - MS2 Daughter Board)

NOTE: Please ensure you have one of these daughter boards inside your ECU before continuing. If you have a black microprocessor, then you have an MS1 and these manuals are NOT for MS1 see here for MS1-Extra Manuals.

Please Note:

All of these instructions / diagrams are to be used at your own risk, like most things there is more than one way to do the same thing, what we have tried to do is to offer a method that we have tested or that others have tested for us. No warranty expressed or implied.

Use at your own risk.
If you do have any suggestions or settings that work please let me know Philip.Ringwood(at)ntlworld.com

Internal Wiring

Spark output comes on D14, D15, D16 and JS11 (COP) see HERE for options on driving the coils. 4cyl could use a distributor or wasted spark if desired.

Settings

Enable the right Daihatsu mode. D14 as the spark output and choose single coil, wasted spark or COP.

You likely want to set you cranking advance to (say) 5deg.
