Fuel enrichment table problems
 
6 Attachment(s)
Hi
I just wondering if someone can help me with this, Im testing and testing and seems like i can't find the solution of the dilemma.
I it goes to lean when i shift ,and no matter what i change it does not do a big difference
I don't have the secondary vacuum throttle flaps , and a big throttle body. 2250cc sencondary injectors and 850cc (OEM secondary) for primary , it is single turbo of course.
Should be easy to solve , but is taking me one and other head ache, and lots and lots of fuel , without positive result , my aim thou is just to boost her to 1 bar (14,7 psi) but ATM i just boosting 10 psi
I will attach some screen shot , so you can know more or less what I'm talking about

ok , a bit better , for no known reasons it went a bit richer , not that concern yet , but the fuel accel table in between the shifts are way better

Ok , it seems like i found my mistake

First you have the DTPS trigger
Then Accel limit
Access Sustain
And Accel Sensitivity

Here is the tricky part , as you put smaller numbers the DTPS get bigger , so for example , to thirgger it you put a 15 , will be harder to trigger the accel ¨pump¨than a 3

The access limit is pretty much easy , in this case , it will never go more than 141% of the fuel map
Access pump sustain is how long you what to the fuel ¨pumper enrichment work , easy to know when you datalog the wideband o2 sensor in the shifting
and the Accel sensitivity , is how sensible will be the delta throttle position moment to make the fuel pump work (a bit confusing and i don't understand well about this and the difference between this and the dips trigger , but hier number more sensitive to the throttle position so easier to activate it.

Ok, I made it!!! Finally , that was all the problem , now the air fuel ratio is exactly where i want to.
