ok well like it says i have a 2.5 block getting dropped in my car as we speak but my question is can it be run with the stock wrx ecu, how much slack does a stock ecu give? what are af ratios on a bone stock 2.0, Any help will be awesome but the only reason i ask this is because i may have to drive it for a week or 2 with the stock ecu if i can.. Thanks in advance
You're a brave man. Dropping a new engine in your car before you even know what it'll take to get it running
But will it run? As in: Can it be driven until EM gets done? Has anyone done it and what could someone expect? Yeah, I am very curious too. :naughty:
Not that I am recommending this by any means, but kept out of boost the ECU might be able to compensate when it's in closed loop... I wouldn't want to test this theory on a new motor though.
Moose is correct. It will likely "run," HOWEVER I would NOT break one in like this. Proper break-in requires a wide variety of throttle, which I would NOT suggest untuned... SS
yeah i have a 255 installed, also i have a set of pinks but i've been lookin in to some of the reflashes what do you guys think about openecu? lol
