I don't know much about COBB OTS maps, but if I was FBO w/ aftermarket turbos, i'd be getting a custom tune written for MY car to prevent these issues.

I'm sure Buraq/Ken from Wedge will be able to figure it out real quick, along with some other Cobb guru's. My .02 would be to have a tuner write flashes for your setup, instead of a generic map.

i agree and plan on doing so come spring. as for being fbo and upgraded turbos i don't think has anything to do with it...never has happened before until recently...never when i was running procede and not until now on cobb (have had for a little over a month now running the same map.)

just looking for some advice maybe what else to log..?

I can't see those logs, are they private?

Second the one log I can see was uploaded December 2nd and leaves A LOT to be desired. It doesn't have any of your trims logged so I can't see those but what I can see is that post shift you were still WOT, requesting a load of 190 and had AFR's in the high 14's on pump gas.

Your LTFT's maxing out is a really bad sign as that means your STFT are maxed out and were probably doing so regularly.

You REALLY need to tune your car for the hardware you are running. Leaving it until spring is NOT recommended.

the highway cruise log was private sorry...you'll notice that while cruising fuel trims show around 25%..is this normal? is there any other reason i could be getting these codes while cruising? I've been fbo with upgraded twins for 4 months now 3 months of which on procede... i know i should be tuned for my hardware but its winter in new york currently and to get a custom tune wouldn't do me much justice i feel (i could be wrong though trust me that was the original plan) simply because its winter...grounds cold, weather sucks...always either raining windy or snowing...because of this it makes it hard to get a good wot log. if you notice my ltft hold at 0 during wot on my 3rd to 4th gear log...that log was from last night, hours before our first snowfall of the year here...

Are you on aggressive map and also what octane fuel? Could be bad fuel..

stage 2+fmic aggressive LT on 93octane...i thought that too, i got really cheap gas a few weeks past, though it was from mobile...3.11/gal when other places were around 3.20/gal...haven't gone back there bc i started getting these codes with that tank...been using sunoco since and seem to take longer to see these codes show, usually show around 30 mins of highway driving cruising round 2k rpms

I still don't see a highway cruise log. Only the one in December and the 3/4 log in January.

Your scalar could definitely stand to be adjusted, that is fairly high. Not as familiar with the Procede but it may have been adjusting your "open loop" for your mods and fuel. Given it's colder now....your trims would increase as the air is more dense.

Get a pro-tune....they will send you a base map for your mods and in the mean time you could just use that and have them adjust it if needed. When the weather is better they will work with you to dial everything in. If they don't agree to that...go with somebody else but I know most of the tuners will.

bump the fuel scalar for both banks to around 1.1.

adjust accordingly and the codes should go away.

Ok I will give this a try thank you for your reply...I also failed to mention that when I was running procede I had a fuel flash from them to run a 50% e85 mixture...this before the oft came out..so I had to send the dme into them...they said I can run pump or mixture...just use procede to load proper map...SO hopefully this helps... thank you again!
