wideband readings

[blackmonte]

What kind of wideband readings are you guys getting idle warm in park ? On a gas car 14.5-14.7 is normal . I am staying at 12.7-13. BL is 130, Iac 21, TPS .42,AF 4, I have a 6.0 TT chip , LS1 MAF , translator set to 1 on base to get the block learn down to 130. Fuel pressure is at 43 hose off,

Mine runs way too rich but in closed loop the Ecm does a pretty good job of keeping the 02's in the 14's. In open loop WB is around 12:1 idle and my blms are 111-115. Haven't figured out why so rich yet. Are you running it in closed loop?

Yeah, I think Eric has these 6.0 E85 chips to idle closed loop.

On some of the more recent E85 chips, I've been using open loop idle to smooth it out a little. If it's switching to open loop at idle, the A/F will end up somewhere around 12.5-13.5 usually. It's the same for gas or E85 if your wideband is set up for gas.
