Thread: Wideband safc tune

timing still not set.

ahhh then you arent even really feeling the true gains from your tuning adjustments.

did you get those 7e's in and gap them? bogging could be from the plugs

yeah i got the plugs

what did you gap them to?

.28

awsome, when you get into the range where it boggs, what do your air fuel ratios read? does it change raticly? in those ranges of rpm?

well right now at idle its at 14.8-15.2 at half throttle its at 13-14 and wot its 12.1-12.5 but it still feels real rich. my gas goes down like nothing, i don't know if its normal when turbod

well your wideband will tell you if you are running rich or not. it really depends on how you drive, if you drive the car in boost ALL the time then you are going to definitly have a more rich effect and your gas mileage wont be great.

if you drive at like half throttle almost all the time i would lean it out some at half throttle and that should give you a little better gas mileage if you think that where you are at right now is too rich

I have my throttle points at this: Low 8% High 50%, i noticed with the High set to 36% i would get this terrible sputter at mid rpm ranges at about 25% throttle, i noticed that it was adjusting in between my high and low throttle setting at that rpm which on low throttle it was around -20% and my high throttle is set at -13% so the wideband would read hella rich. 10.0 but thats as low as it goes and then the sputter would occur. i moved the low to 50% and now it runs great with no sputter at any rpm or throttle position. With my experience im running a T25 at 8psi on a JDM DE motor with S4's, open 3" downpipe, tubular manifold and more. At wot i read a steady 12.5:1 which is a little lean but there is no detenation at all and it pulls hard as hell at only 8psi. i even tried to put my high throttle settings at 0 to see if there was any change and none. still stays a steady 12.5:1 under wot which leads me to believe my 370cc injectors are at the max at 3 bar fuel pressure. i need an afpr so i can up the boost to 12psi or more. but i havent gone any higher than 8psi for that reason that its already running at that a/f ratio.

oh and just for the note at cruz under practically no throttle i run 15.5-16.5 range. there is no harm at all in this, your not under boost and a normal n/a engine will read this a/f under cruz. thats why i got 35mph on my last long trip on the highway. under partial throttle when the boost guage is say at 0 im at a 13.0-13.5 range, and higher throttle im in the 11.5-12.5 range then at full throttle im at 12.5 steady
