Anyone have an ls swap into their hatch or crx...... if so does it run rich ... i hear its setup rich..mine blows a lil smoke when shifting.......?????

 

are u using stock exhaust system?

 

no..... i have custom 2 1/2 piping

 

There's a million and one reasons that could be happening. What ECU are you running? Are you running a fuel pressure regulator? What color is your oil? What fuel pump? etc etc etc. Explain your set up.

 

pr3 ecu..... black oil......everything else is pretty much stock

 

You're running a B16 PR3 ecu with a non vtec LS motor? Step number one: get the right ecu!

EDIT: And oil shouldn't be black...

 

Oil being black = change it.

PR3 ECU = Lean as hell VTEC, going to throw codes.

I'm not sure if the fact that it would throw a ton of codes because you're not using it with a VTEC head means that it's going to run on limp (hella rich mode).

Either way, get yourself a PM6 or a PR4, sell that PR3 on Ebay or save it for later...

But first things first CHANGE YOUR DAMN OIL BOY!

 

lol.. you dont run on "limp" mode.. it just throws a
