Shouldn't really need any adjustment unless you live near space :P

 

i think my biggest issue is i don't under stand the math thats going on. and i also don't understand why almost everyones tables are so close to being 1:1 where mine are radically off from that no matter which right or wrong table i am adjusting.

 

What math? Its a table this kpa == that load.

Even at idle your at some kPA pressure and if its rich its too much load.

Load == fuel

 

thats how i understood it but i get confused as to why my tables end up so far from 1:1 to get it anywhere near a normal AFR

 

The table itself is like a broad adjustment to the fueling while the 3d table is like a fine tune for the fueling. In a sense you could be 1:1 and tune out the difference with the VE table but I prefer using the 2d table to get close and then fine tunning.

My 2d table numbers were never 1:1 either. I found in the vacuum portion i was always less load than kPa and in the boost section it was more load than kPA. I'm sure if i had this nice 3d table I could have made it 1:1 but it would have been like 65-70% at idle and over 125% during boost

 

0 0
10 10
20 20
40 40
60 60
80 80
100 100
500 680

is what the kPa vs Load looks like

so that means that from 0-100 its all vacuum? because the way i see it 101kPa is 14.7 which is when we negate atmospheric pressure and go into boost. do all the 0-100 load values will be lower to lean out the mixture under vacuum?

 

Yep 0-100 is all vacuum with 100kPA being 0psi or 14.7psi(A). That (a) is important as it means absolute pressure with 0 being perfect vacuum.

I have an older map of my car i can show you how my kpa vs load looked like. You should be able to tell vacuum settings took some work. lol

I never had a 1:1 relationship either. It's just not 'right'. But, you can choose whatever you want, as mentioned, and use the 3D VE table to fine tune.

 

new update, car idles, and drives pretty good under vacuum except it still has problems with tip in going lean. also when going into boost it shoots really rich i guess lowering the load on the boost kPa should help.

 

When your getting lean tip in pay attention to the kPA,load, and rpm its at. You may need to adjust the async tables or adjust those respective lower load VE points to tune out the tip in.

 

gotta be async cause i have the table tuned to take care of rich at the same loads and rpm as the lean

 

Looks like your making progress now though

 

finally

 

when i had that issue with a customer car i just forced it into open loop mode and adjusted the cells and fixed it .. it kind of felt like a hack job to me but it worked..

if you fix it without doing that please update so we know how to do it. when i tried to correct it with async tables it didnt work.

kudos to roadspike for helping you so much.. hes a very helpful and knowledgeable guy for sure. where is his EvomGuru badge already? lol

 

i agree on the guru badge, if i could send a beer over the interwebs i would!
