PhoSho Posted May 16, 2023 Report Share Posted May 16, 2023 Hello All, I have a freshly installed WRX104X in a 2004 USDM STI. The base configuration files in PClink list the STIs by version. I have heard the 2004s called both a Version 8 and a Version 9. Which one should I be using? It seems like it already has some type of base configuration on it, but the manual specifically tells you to load a config from the list so I just want to make sure I start off on the right foot. I appreciate any help. Quote Link to comment Share on other sites More sharing options...
Adamw Posted May 16, 2023 Report Share Posted May 16, 2023 If you have a WRX104 ecu then this what we call a version 10. Quote Link to comment Share on other sites More sharing options...
PhoSho Posted May 16, 2023 Author Report Share Posted May 16, 2023 Ok, that makes way more sense. I saw in the details for the ECU V10 stated and listed as being for 04-06 STIs, but I didn't realize that it referred to the car - just figured it was the ECU. I have owned a lot of STIs, but have never caught up with the version numbers. Thank you for the help! Quote Link to comment Share on other sites More sharing options...
Adamw Posted May 17, 2023 Report Share Posted May 17, 2023 Yeah identification of Subarus after V7 is a bit of a confusing mess - but still works better than using years. Subaru officially stopped using version numbers after V7, so users made up their own versions after that. For most of the world they refer to the "bug eye" as V7, the blob eye as V8 or 9 and the hawk eye as V10. USA decided to do it differently than everyone else, they dont differentiate between V8 & 9, they call all blob eyes V8 and the hawk eye V9.

PhoSho Posted May 17, 2023 Author Report Share Posted May 17, 2023 If the WRX104 is specific to the V10, is the V10 base map already loaded onto the ecu? Do I need to load the V10 from the base map directory at all? (All I have done so far is physical install, firmware update, and verification of pre-crank fuel pump operation).

castillaricardo Posted May 17, 2023 Report Share Posted May 17, 2023 It should have the base map preloaded, but it wouldn't hurt to at least do a "Compare" to make sure. The function is under File > Compare. Quote Link to comment Share on other sites More sharing options...
