Overrun only cuts fuel upon deceleration. It's there to help with engine braking. How would it help if i'm accelerating to 7k out of boost (who does that?) and my afrs are 13-13.5 when they should be more like 14.5-14.7. I understand being safe but i've never seen 13-13.5 in non-boost cells before. Maybe he does that so autotune doesn't make him go dangerously lean in those areas.

 

My tables are set up for11.5-12.5 in boost, 14:1 at 100kpa, 15:1 @ 40-80kpa, and 16:1 below that aside from minor variations. Only hiccup I have seen is that the points above and to the right of Idle need to be tuned more rich to prevent poor off-throttle response. So far this has worked well for me and gets the same or slightly better gas mileage as my completely stock 97

 

How about this?


All of my questioning comes from me really not knowing exactly what I should have. Especially when I see someone running tables very rich in comparison to my own.

 

yeah, how bout some expert opinions on this? I based my AFR targets on what I gathered from a post Jerry made and have this:



I think he was recommending a 13.3 at idle to avoid missing but i had better results a lil leaner at 14.0

 

im never in those 13.5:1 cells anyways.


the stock ecu will take you to 12.0:1 at WOT with no boost, i figure if for some reason if im at 5600RPM out of boost i need a little fuel to prevent knock.

 

i know this so newb of me, but i get more confeused the more i read about this ****...should i just not read the problems unless i am seeing some myself...should i just focus on all the positive **** and just learn how to get the car running NA before i get into all these problems that ya'll are having...**** it, its too late, i took the plunge

 

It's not hard, we're not having problems, i just like bringing **** up all the time to **** people off.
Really though, it's not that hard.

 

Yes these are not neccesscarily problem thread moreso they are dicussion threads where we all compare notes on what is working for us. I would note when you see problems discussed here on these forums. And try to focus on the positive until you get to where you feel comfortable with the MS system. And then if you can look in to any problems you might encounter with out being as discouraged.

 

Are these good settings for the custom file autotune settings?

; Tuning block parameters
; Global limits on tuning, outside the box and nothing happens.
xLimits = 1000, 7000 ; RPM
yLimits = 40, 200 ; MAP
zLimits = 10, 200 ; VE

 

yep should be

 

mine's more like this

you want it a little rich just off idle, otherwise it will jerk a little. bring your cruise ranges to 15.5-16.0. there are some zones you'll never hit, so they don't matter.
