I work at a mitsu dealership it just opened a few months ago n we bought a 03 evo with S-afc2,manual boost controller,intake,upgraded intercooler,full exhaust,650cc injectors. the car ran fine when we first got it but the owner decided to mess with the s-afc n the car fell on its face. they had a guy come n try to tune the s-afc n he didnt have a clue wat he was doing. so i was the lucky guy stuck fixin it i got the car runnin better but it revs out at 4500rpm n it never used to do that n i cant really tune it if i cant go over 4500.i dont know if the guy who tuned it b4 me messed sumthing up but we cant get ahold of him.plz sum1 hlp me i am losing money workin on this car!

i would say you need to get a datalogger and then try to tune it, You are asking for trouble tuning without it or without a wideband 02. You should look for agood shop around you that can tune it. I know one of the more exspensive shops near me is $150 for a Dyno tune with wideband for the SAFC. Good luck with it. I hope you get everything straight, or see if you can find someone who will swap you part for part and return it to stock, then disconnect the SAFC.

First off make sure the settings are right;
start with the [etc] menu by scrolling down to highlight it and pushing left on the joystick in the center of the control knob to advance to the next menu. Highlight the [sensor type] option in this menu and press the joystick to the left once again, scroll down with the joystick until [karman] is highlighted, now press in on the joystick to bring up a cross shaped sub-menu. Press the joystick to the left to illuminate [Pr] and push in once again to go back one menu, once you can see [sensor type] and [car select] again scroll down to highlight [car select] and push right to advance. Here you should see either "4 cyl" or "6 cyl" and an arrow, twisting the control knob counter clockwise will decrease the number of cylinders. We want the number of cylinders to be set to "4 cyl", once this is complete push the joystick to the right to illuminate the arrow. Twist the control knob clockwise until the arrow points up and to the right, now press the joystick to the left to back up through the menus until you are back at the main menu.
Do this first and I'll check back later.
