mwakima Posted April 4, 2015 Share Posted April 4, 2015 Hey guys, I'm working on a swap for my 2005 outback 2.5i 4EAT. I built up a ver. 4 STi engine with forged internals and custom fuel lines plus I also swapped in a 5MT 4.44 JDM STi gearbox. Here's the engine bay as it sits today; wiring is all over the place but wanted to verify the car starts and idles o.k http://i1307.photobucket.com/albums/s597/mwakima/IMG_3807_zpsf1fpjfs5.jpg Now trying to start the car using the key and getting the gauges to work correctly is proving problematic; any one with pointers on how to fix this? Wiring is not my strong point! The CAN BUS system is out of whack with the original ECU, TCU and auto tranny unavailable. I can experiment and bypass bits here and there but wondering if there's a clean solution to overcome this. Here's my cluster as it sits now. http://i1307.photobucket.com/albums/s597/mwakima/IMG_3810_zpsuulfssjp.jpg Link to comment Share on other sites More sharing options...
Hitokiri_Gensai Posted April 4, 2015 Share Posted April 4, 2015 Im not sure that the ecu can possibly run the engine. The engine is going to have completely different sensors on it than the stock engine. Link to comment Share on other sites More sharing options...
mwakima Posted April 4, 2015 Author Share Posted April 4, 2015 I'm running the JDM STi ECU; the thought was that I could tap into the wiring for the fans, gauges and such. Link to comment Share on other sites More sharing options...
Hitokiri_Gensai Posted April 4, 2015 Share Posted April 4, 2015 In theory, yes, but the canbus system NEEDS to have everything in sync in order to run. Im pretty sure you wont ever get setup to run properly. Link to comment Share on other sites More sharing options...
mwakima Posted April 5, 2015 Author Share Posted April 5, 2015 Alright thanks. I scored the FSM and will give it a shot; I can get the speedo and tach to work but the fuel and temp gauges are being a PAIN. Link to comment Share on other sites More sharing options...
Hitokiri_Gensai Posted April 6, 2015 Share Posted April 6, 2015 Yeah, hate to be the bearer of bad news on that one, but unfortunately, the newer cars are extremely difficult to drop in older engines. Link to comment Share on other sites More sharing options...
compsurge Posted April 6, 2015 Share Posted April 6, 2015 Normally the Er HC is caused by the green test connectors being plugged in under the passenger dash, but I don't know if this applies here. Link to comment Share on other sites More sharing options...
mwakima Posted April 6, 2015 Author Share Posted April 6, 2015 Thanks guys for the replies. The wiring diagram on the service manual really helped; I was able to byass the inhibitor switch setup for the A/T to start the car using the key. Other bits I got working are the speedo, tach and fuel pump. The only thing that has caused me to give up is the stinking fuel gauge; I just can't figure out how to get the gauge working. I'll just use something aftermarket and get the car on the road; I'll get back to this science project later. I'm going to throw in an aftermarket ECU so will explore using CANBus Hubs and such. This really threw me off; we do swaps all the time to impreza's and foresters in that 2003-2007 range and they don't have this wiring system. It didn't occur to me to check for this.

NewJerseyDevil Posted April 6, 2015 Share Posted April 6, 2015 Err HC is your readiness monitoring system... EVAP stuff. Err HC means Hyrdo Carbon Error, don't quote me though. But like said above usually when the green connectors are jumped and the ignition is on this will appear on your cluster. Link to comment Share on other sites More sharing options...
mwakima Posted July 27, 2016 Author Share Posted July 27, 2016 Ah realized I never came back here to say how I sorted out this issue. I worked with Andrew Todd at AGT Engineering in Australia to build a Canbus translator that fixed all the issues with the speedo, temp gauge and other associated Canbus errors. Works like a charm; I have a non-canbus engine now running seamlessly in my Outback.

Max Capacity Posted July 27, 2016 Share Posted July 27, 2016 First off, you need to edit that "Wiring is not my strong point!" If you can do what your did... Next question, does Cruise control work ? What you did is pretty amazing. Thanks for updating us. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.

mwakima Posted July 27, 2016 Author Share Posted July 27, 2016 Haha well after getting together with Andrew, it was all pretty simple actually. My version of the car did not have cruise control so I didn't need to bother with that. It shouldn't be too complicated though to get that working. Basically what Andrew and I did was figure out the components on the car that we needed to convert to send on the canbus network. In my case, the water temperature and gearbox speed pulse were the only inputs that wouldn't work correctly outside of the canbus network. Andrew then went on to build the translator which was very easy to wire in to the car. Link to comment Share on other sites More sharing options...
Max Capacity Posted July 27, 2016 Share Posted July 27, 2016 Some pretty talented people have done the auto to manual swap in these cars, none have got CC to work. Dave Brady, shop foreman at http://www.enhancedstreetperformance.com/ was one of the first to do the swap. You might want to contact him and chat about your swap. That's also where my Tuner runs the Dyno. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.
