Well I am assuming the little screws near the main part of an intake are for the air/fuel but I am not positive so hopefully you guys can help me out.

I have a hotshot cold air intake, and HS headers on my 95 MX6 LS (2.5 V6, auto trans) and was curious if you could tell me how to adjust these to optimum performance for racing, as well as good gas mileage for regular driving.

If more information, or pics are needed jsut let me know and I will get them posted asap. Thanks!

ok....i think that adjustment screw you are referring to is the idle adjustment found on the top of the throttle body.

Being that our cars are Fuel Injected the air/fuel ratio is maintained by the computer. It has the ability to compensate for many of the bolt on power mods to keep everything running rather effeicently. If you wanted more control, look into getting a S-AFC but those have yeiled very little gains (if any) on our cars for the money invested.

let the carm warm up
set it to where its at 800rpms or the car is most 'smooth' at. This is a idle screw. it only does anything at idle. the car in theory would run exactly the same with or without it.
but inbetween shifts the engine would fall on its face do to a massive vacume leak :)

i think you missed my point. There is little you can do to adjust the A/F ratio with your current setup and the gains would be minimal if at all. Besides...its usually one or the other (high performance or fuel economy). The design of our engines leans more toward fuel economy.

Hello,
My Mx6 1993 2.5L is reading of at very rich mix (using a Narrow band sensor)
Would any of the information read from the gauge be useful at all?

I know its more reliable with a wideband sensor. I just wanted to get some reading if it was high or low,
(Smelling the exhaust tells me its definately rich <img src="http://www.mx6.com/forums/imagesmx6/smilies/smile.gif" border="0" alt="" title="Smilie" class="inlineimg" /> )
But id want to make it get closer to ideal mix.

Anyone have tips what to do other than getting a wideband sensor right away?

Thanx <img src="http://www.mx6.com/forums/imagesmx6/smilies/smile.gif" border="0" alt="" title="Smilie" class="inlineimg" />

af mix

check between the battery and fuse box .... little knob sticking out that is plugged in ... the top has i lid which you lift off and you'll see another button inside that you can turn ... its completely round and you cannot use a long nose plier cause no space... use a piece of aerial or small socket and press down reasonably.... turn left for leaner mixture, turn right for richer mixture
