Conversion Q's - c7 into a 0BD1 EG ...issues with ECU's

[BseriesPLZ]

hullo all. Before i jump into something else ~

I have a 1992 honda civic EG. Si , 0BD1 ecu and thats it really.
I also have a 1999 ITR , ready to convert over baby indeed.
Anyway , only thing i am pondering is the ECU/harness setup - i intend to run a conversion harness and re-use my existing wiring and add wire for the usual vtec solonoid and extra(knock sensor i believe?) ~ but concluding whether to get a cheap 0BD2A-0BD1 harness , or simply get a stand alone 0BD1 hondata and jump the chase.
IF its the hondata , is it simply adding a couple of wires to it for additional vtec solonoid etc ? And , does the hondata come with a base map or do i have to get it tuned asap...?
any thoughts cheers Will

2 option

1- ecu conversion harness if you retain the dc2R stock ecu

2-hondata obd1 chipped ecu

* Aust model Si already came with vtec wire, so you can just leave the solenoid alone, however knock sensor needs to be wired on*

option 1 would work out alot cheaper (proaaably more than 1/2).. unless u are wanting more mods..
