DSMlink AFest and Wideband

[Mindslayer]

I have an issue. My car pulls strong and on closed loop my A/F and W/B are very close at 14.7 and 15.1 give or take. I've changed my AF estimater to match my injectors. (850cc. 330 Dead time and 37psi 1g MT AWD). My question is when I go into boost(10-15psi) around 4500-6000 my AFest is like 10.1 or 9.1 and my wideband can range from 13:1 to 16:1 at times. Why is it so off? I'm running 93 oct and for most stations it had 10% ethanol in it and 0-0.4 retarded knock.

My set up is 2.3L 8:8:1, JMF SMIM, fp2, Rewired supra pump, 850, AFR, AEM fuelrail, AMS 60 trim, street core FMIC , 3in turbo back, PLX M-300 and WB is in cat location. Can someone help me with this?

First off, your mod list says you have an afpr and it is still set at 37psi. And that was with the vacuum hose unhooked, correct?

Yes i did. I found out the problem. Since I'm running the WB in the CAT location. It's a delay reading verses having it in the stock O2 location. Soon I will make that adjustments, also because Im running super rich and if some fuel is left in the cylinder, it can throws off the WB and the ECU may try to correct things and the WB thinks i'm running lean.
