kfx is making drop in plug and play megasquirt units for the sportage. its doesnt show up on the website under the sportage but under the sephia just let him know its for s sportage and he'll load the maps. it comes with everyhting u need to either solder on your own ecu plug or plug it right in and it will fire your sportage right up. this opens up a world of tuning for us from changing things around for and intake and fre floeing exhaust to turbo and stroker tuning.

theres your link and if you have any questions and your a member of street kias your lookin for bhurlin...if not post em here and i will ask for you.

Yep...

fidling with the idea some time now
But cash was a problem
seems to be the only reliable way to go for our engine managment
in a reasonable cost.

and a question
in somple words what is does the wideband o2?

ok think of regular o2 sensor as a speedometer that only reads in 20mph marks and a wideband o2 reads in 1mph marks..its much more sensitive and accurate which makes it better for dead on tuning. the 600 is a bid outta my price range but im afraid if i bought all the stuff myself i wouldnt be able to get it right
