There is the option to convert a ‘7730 V6 Memcal to a ‘7730 V8 Memcal.

Modifying the '7730 V6 Memcal for V8 is low cost, simple, and very effective. I've been there, done that, and the results have provided many, many miles of smiles.

Biggest issue is if the hardware is in different locations. '165 code sends a message to injector driver to fire injectors but 730 board says "Nobody at that address."The '7165 ecm uses a 16k memcal eprom, the '7730 uses a 32k memcal eprom. Completely different instruction set.
7165 can run $12P Holden speed density code.
More Information, How to connect ESC module in place of a Memcal knock filter see attached.
I see some clarification might be required when converting a ‘7730 V6 Memcal to V8.
1. Install jumper into '7730 V6 Memcal, no other '7730 V6 Memcal modification needed or required.
2. Install ‘7730 TPI 4K knock sensor into engine block. I use Standard Motor Products knock sensor part number KS6.
3. Connect Knock Sensor connector wiring directly to ‘7730 pin F9.

Hey All, 7730 installed w/v6 mod memcal, had to change injector flow rate to 24 to get it to clear flood and run, the biggest issue is I a getting CTS & MAT Low errors they are connected to E16 & F 16 grounded to B5& B6.
Tuner Pro RT latest and & $8D. Both worked connected to earlier ecm . is it an addressing issue or what ???
both edited to show F instead of Celsius reading 32 and not changing, start up engine temp reads 265 stone cold????????????????????

The schematics I have for the 7730 Sensors:
F16 - MAT Signal
B5 - MAT Ground (Low Reference)
E16 - CTS Signal
B6 - CTS Ground (Low Reference)
Maybe try the attached $8D .adx file, "WITHOUT" the 10K jumper on the ALDL Cable.
