    Default E38 log after setting up for vve adjustments, crazy afrs

    Hey guys, I have followed the swingtan and efilive autove tutorials to the T, read them and alot of other stuff over but have just applied the new calibrations so I can make a log to apply to the vve table and the wideband is showing afrs so high and low that I am wondering if I missed something or if it has something to do with another issue Im dealing with. If someone could check out the log, this is with all of the pids changed in the tutorials and the maf wire unplugged. Thanks

    Ps I am aware that there are some bad pids on there I just added to check out and the log is short because the lambda hit 1.400 and that scared me at only 1800 rpm.

    Ok, so I took screen pics of ll the setting I changed as instructed in the tutorials. Ill put them in the best order that I did in that I can. I drove the car and got it up to temps, shut it off, unplugged the maf and uploaded the calibrations, then started and took the above log. Ive done the tutorials 3 times now and then compared the tunes and I am pretty sure I'm following them correctly, is it possible that my ve table is that far out? When I run the car on my base tune the idle sucks, but driving is alright and my stft go between -4 and +7 with ltft within 4.

    I hate being the bearer of bad news, but there's something you should know about.... the E38 controller suffers from a thing called "rich after flash". It happens when you flash in a new calibration on a hot engine. There is no 'fix' for this... you just have to drive it out (some say 10min drive, some say 20mins, some say a few hard accelerations shortens the time... I really don't know exactly how long it takes for the richness to wash out). You can do lots of reading about it over on the HPtuners forum. Enjoy!

    Running rich is fine, its the super lean reading I was worried about when stoich is commanded. I sat in the car for a good 10 minutes after the reflash to let everything get back to normal temps, its -5 here on canada Anyways was just looking for a second look is all to see if I missed anything, a few pics didnt load for some reason of the other steps ill post when i get home
