Hey guys Ive been doing a little searching because Im about to swap a JDM LS into my integra. So its my understanding that if I get a JDM LS ecu I wont have any issues to worry about like the ckf sensor and the evap or anything right? What if I go with a USDM ecu? I know how to trick the ecu for the ckf sensor but will I have anything else to worry about? Thanks for the help guys, trying to run code free/mostly legit!

 

Why an LS to LS? GSR isn't much more $ for what it's worth. Code free is easy with the same harness and manifolds.

 

actually Im going GSR to LS... gas prices here in california are killing me. I dont have a usdm ls manifold...

 

yeah brotha. 50 bucks to fill our integra is BS.

 

the ls isnt going to get better gas milage really. if you want to save gas gearing is your friend and staying out of the throttle. My old ls got 24mpg. my build stroked gsr turbo gets 28-30mpg. go figure lol

 

not necessarily better mileage, but at least I can use regular unleaded as opposed to premium/midgrade

so just to make sure here, if I use the JDM intake manifold that comes with the LS I will have issues with CEL's? what can I do besides swap to a USDM LS manifold to remedy the situation?
