What's the difference between P74 and P75?

program wise nothing, but internally they differ motherboard wise.

cxhatch02,
You can also run an OBD1 PR4 ecu and even a (reprogrammed to LS spec)SOHC DX/P06 ecu to power your engine.

yes, its all in the eprom chip.
An LS reprogrammed chip & then installed on a P06/DX ecu basically converts the P06 to an LS ecu. That simple.

An OBD1 PR4 should work, also a p06 (non-vtec civic) ecu will work, so will a P28 (but you won't need the vtec circuitry, so only if you find one really cheap.

Or a P74/p75



Hondata will be reprograming the ECU's, so basically it is only a vessel for the software.

Here is another helpful resource.
