EGO correction (STFT) as a table.
Pretty self explanatory.
Instead of a single value to use across the entire VE table, make it an 16x16 table (so that it matches the scaling with the VE table), basically the same thing as the LTFT table, but only keep it in RAM instead of flash.
TunerStudio should be able to display this as a read-only table, with maybe the option to apply these corrections to the VE table.
Thoughts about this from the developers?

If I'm reading this right, will the ego correction table do what you need? I've used it before to limit idle area correction and limit boost correction

No, I need the ECU to remember what the correction was at idle and in boost for example, rather than to seek the target each and every time from zero.nathaninwa wrote:If I'm reading this right, will the ego correction table do what you need?

Re: EGO correction (STFT) as a table.
Sounds like the same function as "LTFT" - disable burning to flash if you don't want it?

Re: EGO correction (STFT) as a table.
That sounds like the tuneup should get fixed instead of relying on a short term correction table. It's always trying to target 100% so the swings through it would be hard to redefine
I tune my idle points so I'm near 90% so I come in a little rich, not something I'd want to tune out
Once the air correction is setup proper, my tune stays within 5% year round

Re: EGO correction (STFT) as a table.
Sounds like a plan, how do I get it to update the table quicker than 1 timer per second (minimum allowed value for "Sample interval")?jsmcortina wrote:Sounds like the same function as "LTFT" - disable burning to flash if you don't want it?

Re: EGO correction (STFT) as a table.
why would you want it to update even at 1 time per second..??

Re: EGO correction (STFT) as a table.
Sounds like what the OP really needs is to run VEAL for a little while and get his VE table in order. Or simply accept that there will always be a slight variance in measured AFR, he will never get it to perfectly match his AFR table.

Most likely he is trying to get it to work like OEM.
Megasquirt is not for use on pollution controlled vehicles. Any advice I give is for off road use only.
