frank_ster Posted October 29, 2010 Author Share Posted October 29, 2010 Aside from the spark plugs ignition cables can be a culprit too, fresh and clean cables helps. (OK, if you have directly connected coils that doesn't apply) Another issue that can cause rough idle is if the ignition is too early. Too fat mixture on idle can also cause the engine to have a rough idle. And maybe you should check out the injectors to make sure that they are matched. May pay off in the long run. Unevenly matched injectors can in worst case burn a valve. (I know that from experience) well i have a wide band o2 sensor. i played with the afr at idle it seams to be the happyiest at 13.5 afr at idle. and i have played with timming also its pretty happy now. what still bugging me is the stock tach, it works one out of 5 times. when it works the idle is controled and etc. Now that's thinking out of the boxer! fyi all 05 + legacy's have built in code reader Link to comment Share on other sites More sharing options...
Verwilderd Posted October 29, 2010 Share Posted October 29, 2010 Well after reading your entire thread, I gotta say....I'm quite impressed....The engine seems to rev VERY fast! Well done! I'm anxious to see a finished project. I would love to hear some clips of it driving. Link to comment Share on other sites More sharing options...
Mega Users seabass07 Posted October 29, 2010 Mega Users Share Posted October 29, 2010 Have you gotten anywhere with controlling the transmission? I'm curious about how it will act with proper control. Link to comment Share on other sites More sharing options...
ehsnils Posted October 29, 2010 Share Posted October 29, 2010 well i have a wide band o2 sensor. i played with the afr at idle it seams to be the happyiest at 13.5 afr at idle. and i have played with timming also its pretty happy now. what still bugging me is the stock tach, it works one out of 5 times. when it works the idle is controled and etc. That is a bit interesting, and it may indicate that there may be a voltage difference for the signals that is causing problems. Maybe you shall check all the grounding spots? If the voltage isn't going to zero for the signals from the sensors but flats out at +1V at low instead it may be enough for strange things to happen. (I did experience that on a Ford Sierra with a badly grounded ECU, as soon as I connected a measuring tool everything started to work - it was that close.) Even placing a resistor between signal and ground could help. Or possibly the other way around - a pull-up resistor lifting the high voltage. But be careful - some inputs wants a lower voltage as high voltage. 0/3V, 0/5V or even something else. Link to comment Share on other sites More sharing options...
Laverne Posted October 30, 2010 Share Posted October 30, 2010 If the ECU is tuned for boost that will cause idle and overall run issues as the A/F ratios will be a mess, even at idle.. Link to comment Share on other sites More sharing options...
ClimberDHexMods Posted October 30, 2010 Share Posted October 30, 2010 http://www.msgpio.com/manuals/mshift/7segment.html Was wondering about this as well, using the stock gear display but with MegaShift. Guessing that's your plan. Was hoping to get the TCU to do it, but as you said the TCU is going to be pissed...

Laverne Posted November 1, 2010 Share Posted November 1, 2010 ok, i know i say it alot.. But you still havent hooked up the turbo to intake ( atleast it doesnt look it) Id like to see how it will all fit. I see the front mount, how does that run to the out of the turbo then to the inlet of intake? Link to comment Share on other sites More sharing options...
TheWeatherWarrior Posted November 1, 2010 Share Posted November 1, 2010 I know this might be a repeat question, but how much, if any of the front framing did you have to cut. I'm not sure I can tell by the photos (and not owning that year or similar). Is there any compromise of the frame, which would affect the torsional strength of the body?

I'm not sure I can tell by the photos (and not owning that year or similar). Is there any compromise of the frame, which would affect the torsional strength of the body? i cut the upper and lower rad supports, then replaced the lower one with a 1-1/2" square tube 3/16" wall and the upper one is a removeable angle iron 3/16" thick. this won't affect the structual regidity of the car becuase its mostly done by the unibody cab ie window struts and door posts. also what i replaced the parts with is much stronger than original.

I see the front mount, how does that run to the out of the turbo then to the inlet of intake? it will be the exact same routing as i had with the 2.5 subie engine with the holset turbo and the very same front mount IC. that is the easiest part of this whole swap but the pipes kinda get in the way of what i'm working on to get rid of a few bugs.

snow05gtRI Posted November 1, 2010 Share Posted November 1, 2010 did you have the IC charge pipes hooked up when you made that drive around the block? or anything hooked up? or just open throttle body? Link to comment Share on other sites More sharing options...
