wat is a standalone...hondata, motec, etc....
well hondata is not really a standalone ecu its like a piggyback system more or less. a stand alone system is like the sds/motec. The diff is the sds/motec has no distributor (just coil packs) and you run everything from a screen. and you have to mount new sensors everywhere, and you dont use you ecu at all its not even there.
the hondata uses stock sensors a honda ecu and you plug a lsbtop into your ecu to tune it.

Hondata has no option for direct fire (getting rid of the distributor). Motec allows you to use the stock triggers, so you don't need to mount a trigger wheel, and allows you to use the distributor. Running direct fire is only an option with Motec, not a requirement. The only standalones where I know direct fire is a requirement is TECII and SDS.
I know Electromotive has direct fire distributers as well for their Standalone units..
but don't you need a direct fire distributer for 3D fuel mapping, or does this not include the variable aspect of the 3rd dimesion (ignition timing)?

Our distributors only do what their name suggests, distribute a single ignition over the 4 individual cylinders. The actual timing is still controlled by the ECU. If you look at the distributor rotor...

You can see the white part of the rotor. It touches 4 different contacts as it spins around, and the ECU can trigger spark anywhere along that 30 deg of arc that the white contact covers.
They aren't the same as the old distributors that relied on vacuum advance and weighted pulley systems to control ignition timing.
Direct fire is nicer, but it's not required for mapping ignition timing.
