I've changed stock exhaust manifold to custom tubular one, along with turbo and intake pipe and cam lope is comlpetely gone after it

haven't changed anything in the rom, idle is still ~950 rpm, load 30 and timing fluctuates between 5-10

I have S2's and loved the sound of them. how can I get it back ?

 

You like the Rough idle?

Advance MIVEC timing in Idle Cells by 5* increments itll probably lope at around 10-15

 

it's not a IX, so no mivec here

 

Pull ignition timing in idle areas, itll lope more. But youre gonna get higher EGTs.

 

I'm interested as well, what caused it

manifold swap ?

 

You changed some stuff, that changed the VE of your motor, with that your idle are VE might have improved. Basically your car is running better at idle. I spend countless hours getting rid of lope for people you want more... all i can suggest is make it run crappy at idle. Pull some ignition timing bend a valve take a spark plug out all these things will give you lope. But they arent gonna make you faster.

 

Some people seem to get stuck on old-school/muscle car mentality that wobbly idle means more powar!
