	me3.8.3 lean after releasing throttle pedal « on: April 21, 2018, 12:07:44 PM »

hello, can anyone please help me? I have little problem with my car. When I little release throttle under boost I have problem with lean condition for about 1 second and this give me really huge jerking and surging. Is here any map for this?

And problem no 2. still when I fully release throttle my AFR jump to rich condition about 8:1 and then goes back. I think this can be done via KFVAKL map. I´m right?
Otherwise car runs good under WOT or cruising. AFR is OK.

mods:
346cc red tops (scaled)
K04-022
VR6maf (scaled)

many thanks for your help

so, via KFVAKL I solved problems with lean and surging conditions under boost. the main issue seems to be solved. AFR is now OK

can anyone help me with extra rich AFR for about 1 second when I close throttle body? this happens at any load (low, high...).
thx

Hi,

I have the same, but not so high, maybe 11:1 rund about lambda 0,75, for 0.5-1 sec.

i´m not sure, that is normal. I have only a chip, not more.

Are you by any case venting to atmosphere instead of using a recirculating DV?
