E38 Gen4 Big cam running 12 afr at idle and won`t change

[mx_paul]

Good Morning Gents/ladies I have put a big cam in my gen4 and I can`t get the idle to be leaner then 12 afr. I have tried allot of different things to no resolve. The log says the afr is commanded at 14. something but the wide band is saying 12 afr. I have dialed the vve in also. Could someone point me in the right direction please? Cheers

Hiya,
I'll look at your file later tonight and see if anything jumps out. What injectors do you have?
Off topic but curious, does that cam make a lot of valvetrain noise?

Hi thanks for the reply , The valve train doesn`t make much noise , but I haven`t heard a stock engine for a while. I`m making a bit of head way . On p0101-3 i set to 1 trip and no mil , and now when I start the engine the afr goes from 14.6 afr and slowly richens up to 12 afr over about 5 seconds. Thanks for having a look.

I haven't updated to the latest efilive software and can't look at your file. Just off the top of my head I would have a look at your min inj pw. If it is an aftermarket wiring harness, the injector offsets will have to be changed and a lot more if the injectors are not stock.

In-tech.... it's a locked auto-cal file. :secret:

I guess his tuner is going to have to sort this mess out by himself. :laugh:

Thanks statesman. I don't usually spend much time looking at others' tunes, so Lucy says thanks for 'splaining. :hihi: Most times if altered I just start over with a stock file and go from there :)

Pulled about 45% out of the ve table also changed b0146. Still working on cold start atm runs like a hairy Bill Goat when you start it for 20 seconds or so.
