Pe afr level questions

**gambler87** · 08-23-2015

So I've been tuning my 04 comp g using table modifier and dhp

My mods are 3.4 pulley, lq4 maf, 42# injectors, 1.84 rr, 4" airaid intake with aem dryflow filter, and sd headers.

My aeroforce is showing 0 kr, my base pe afr is set at 11.5. But I can't my wideband to go any lower than 12.3 at the hit of wot and it creeps to 12.9 at 5800 in 2nd gear. Still 0 kr all the way through.

I'm just wondering how to get the wideband to get down to 12.0 all the way through wot pulls, so I can start to add timing

I'm seeing 0 kr all the time during wot

Adjust your MAF table.

You need to add fuel, the only way to do that is through the MAF.

Add 5% atleast to start with. See what the AFR does, then go from there to match your commanded AFR while in PE.
