Tuning out rich condition on decel/blowoff

[Keyan]

Is this possible within the parameters of the ecu?

here is a video showing what i am talking about. this is under very light load, but if i actually go into boost and blow off, my wideband goes off-the-scale rich. I have my MAF in blow-through with the BOV before it in the system.

Just vent like I do

[Keyan]

it is vented. i have my BOV set up for atmosphere.

I don't think there is anything you can do about this. Believe the issue is when the BOV opens, the throtle plate is closed, therefore the air rushes back thru the MAF. This air is then recounted again and the ECU adds fuel for it.

thats strange, mine does not have this issue? it is setup similarly



and blackstain, learn how to read.
