Gamma and o2 driven enrich
 

Ok... the two last key concepts i need to learn

What are gamma enrichments and how do i tune them or shut them off for tuning??

how do i control 02 driven enrichments?? mine is staying at 100%

O2 driven enrichments are EGO, set your step size to one and it should work if you have your afr targets turned on.

From the megamanual:
GammaE
Gamma is the total enrichment factor, computed by MegaSquirt® taking into account all of warmup, acceleration/deceleration, barometric, and manifold air temperature sensor correction factors, but excluding EGO correction, which is handled separately (See Corrections/Enrichments, below.) Returned from MS as a percentage value in "gammae."

those are actually differnt. if you have step turned on, and targets off, it adjusts around your sensor switchpoint (stoich) while in closed loop

so how do i turn on O2 driven enrichments...

step size - 0 to turn off

step - 1 to turn on

my stepsize is 0... target tables are turned on...still the guage always reads 100

how can i host my MSQ so i can post it up

it should be 100 IIRC more than 100 means its adding to your VE, less means its taking away from your VE. 100 mean your getting 100% of your VE.

yeah it should be 100...when its not correcting

opps, i thought you wanted to turn OFF. step - 1 to turn it ON. i should slow down when reading posts :nono: i edited my above post to not confuse anyone else

when/how does it use the target tables

(sorry for my stupidity)

i have never used the target afr function, so im not sure. but i would assume that when target is turned on, it over looks the switchpoint in closed loop. you might have to make it where you are always in closed loop to make them work though :confused:

Your questions are better answered by doing your own research. You have access to the most comprehensive source of information for ECUs and you seem to not like using it. If you're going to successfully do anything with megasquirt you need to put in some effort.

thank you... i took a quick breaze thru the megamanual and didnt find what i was looking for. i appreciate u taking the time that i didnt. Ive been spending more time researching on why my warmup enrichments are going crazy (see other thread)

just needed to quote this :bigtu:

come on now... dont get all miata.net on me

do these setting look ok when using an lc-1?

also, when I'm tuning and want to kill ego correction I can just go to "open loop" in more settings and set the kpa switch point to 0...right? Why not run ego correction at idle...even though my tuning is spot on ATM.

thanks.

your switchpoint should be 2.5 for a wideband

i assume because that's the middle of the voltage range? What does that switch point refer to?

correct...the switchpoint is essentially the stoich. voltage... wideband is 0-5 and most (including inovative) switch at 2.5

why don't I want a larger step size? 1% change is not very much. Why not say...10%?
