I have a 2005 Focus ZX3 and I want to tune my engine, which is the next thing I am supposed to be doing according to my buddy who helps with all the work on my car. Which tuner do you guys recommend??
How in the heck will the xcal2 show you that you are running too lean? And 14%? Thats insane and whoever did your tuning should be shot. Do you even know what RPM you are running that lean in? When you adjust the fuel parameters through the tuner it is a "blanket" adjustment and will add that much fuel throughout the RPM at WOT not just where you want it. I would seriously get a wideband on there and see for sure.xcal2 is the better way to go.... Ricardo V. @ Steeda stopped me from ordering xcal3 because he said the programs are better for the 2.0 with the xcal2. Go 93 octane man! kill your governer, change your Rev limiter to 6900... and make sure you take your idle and neutral rev limiter up to 7000-7200 because when you push in your clutch to shift the neutral rev limit (if lower) will totally kill your car. Bog down then jerk and stuff... Lower your temp on your high speed fan... and then tune your spark highest (if on 93 octane) Also tune your car to 14% richer because mine had a problem w/ 93, w/ header intake tb full exhaust. The programmer showed it was running too lean.
