05 RS harness dissected and ready for merge. Anyone know if I will run into any issues with having the CAN bus wires to the ECM disconnected? Looks like they only went to the TCM which wonít be installed as itís all going into a 5spd car.
Almost been a year since the last update! Fuck me. A week or so ago tested the ECU and confirmed communication and flashed it. I hope to finally fire the engine tomorrow (still far from complete). Working on this for a few hours every other week has not been fun.
Wait... What heads are you running? 25D has DOHC, thinking you've got 251 heads if they're SOHC.
STI heads are like 55cc's, 251 heads are 50cc's, and 25D heads are 46.6cc's. Either way, your CR will go up, by either a little or a little more. I doubt you'd be over 10.5 tho, assuming the forged pistons you have are meant for an STI block/head.
