Still goin’
June 7, 2007
I’ve removed every wire in the harness that doesn’t connect to the engine or the ECU. All but about two of the wires from the engine go directly to the ECU and those both go to the combination meter for water temperature and oil pressure warning light.
On to phase 2:
There are a lot of wires that come from the ECU but do not go to the engine. Most of them, I think, will be spliced with the RS wiring but there are some, like the fuel pump controller, that do not exist in the RS harness. My next step is to make a spreadsheet of every STI ECU pin and map it to every RS ECU pin. I’m debating buying another RS ECU, ripping out the connector, and building an adaptor like they make for Honda swaps. Since it only takes about 3 hours to pull out my RS engine it might make emissions a little simpler…
About that, I have talked with the department of ecology on how emissions testing will work with a swapped engine. Contrary to what I’ve read on local forums (Seattle area) the car WILL NOT be tested as a 2004 STI but will need to pass 2000 RS standards. This is true even if all the OBD2 wiring and emissions systems are intact. I was told by a testing station operator and two people at the department of ecology that connecting the 2004 STI ECU to the testing equipment will register as tampering and automatically fail the test before it even starts. Fortunately, I have also been told I have the option requesting a “sniffer” test, but I will need to contact the Washington State Department of Ecology before hand. They will then notify the station manager of the situation and how to test my car.
Parts I still need (at least)
- Fuel pump controller and wiring.
- Front wiring harness – (might make my own)
- Gaskets for VF-39 turbo.
- BPV gasket.
- STI 02 sensors.
