If you're using virtual dyno to look at the logs sometimes it will make it look like your overboosting when you're not. VD autoscales each individual channel, so it can make it look like some really goofy things are going on when they're not. Honestly, i don't even use a grapher to look at datalogs. I prefer looking at logs in spreadsheet form. ATR has a built in datalog viewer that works great for viewing it as a spreadsheet.

Why would going wot from stop cause like a pause [kinda like if you blew a shift point] almost and then full boost?
Also blinking/flashing DTS light? DTS light was off before going WOT, and by that I don't mean totally disengaged, just off. Also throwing P2AAF (quick search said its harmless, but figured I'd add it in just incase its relevant) Thanks for any help! Last edited by M5Rlz; 02-16-2013 at 10:42 PM.. |

2AAF is no big deal as long as it just appears by itself.

All you need to do is just swap maps, no need to uninstall. It shouldn't take more than a minute or two to swap maps.

Hey guys, looking for some insight. I installed Cobb running Stage 1 Sport and have been running it for nearly two months without issue. I really haven't gone WOT or hard on the car at all since I still have my winter tires on and it's too cold for spirited driving anyway. I've checked and the ECU shows no error codes etc. A few days ago I noticed that I didn't hear my Low Pressure Fuel Pump priming the car as it always did when I unlocked it. This has been going on for the past three days. Also, my car takes a tad longer to start unlike before where it was instant. I don't believe this is the HPFP as I've had that issue on my previous car before and this is nothing like that. For whatever reason my LPFP simply isn't priming the fuel system as it's suppose to.
What causes me to think this is something to do with the Cobb tune is when I initially installed the tune the LPFP ran for 10m straight. It really freaked me out but I couldn't stop the update in fear that I would brick the ECU. Now I'm wondering if that initially stressed the LPFP and is now on its last legs. After starting the car today I felt some slight hesitation while idling for about 1m, afterwards it warmed up and drove fine. There also doesn't seem to be any loss in power. Again, if anyone has any insight into this it would be appreciated. Seriously thinking of ditching Cobb. |

I think I have noticed, if I leave my car unlocked over night (in the garage) sometimes I don't hear the prime. But for sure if it was locked, I always hear the prime upon unlocking. Comfort Access

My car with Cobb flash always primes after it's been off for a while.

heyho,
I`ve got two questions which drive me bananes here in the office without the change to get to my car ;-/ a few days ago my chargepipe poped off my throttle body during acceleration. After that I had nearly no power, no push from the turbo... just had a few minutes to my garage where I fixed it. Afterwards I`m just wondering why there was no Enginelight, even no fault code was found with the AP. Is this normal? I would expect a "boost under target" error or something like this, but nothing. with this in mind I come to my second question ;-) My current setup: 135i AT + DCI + AMS FMIC + Forge DV + Catback Exhaust + OTS Stage1+ Sport LT (no downpipes installed yet) the car makes the expected power within the first 2-3 gears but at least at the 4th gear the power is a bit lagge before 4000rpm. The car pulls until 4000rpm but feels a bit held and then after 4000rpm it REALLY makes power... the difference is very noticeable, like changing from 50% throttle to 100% Still no Error codes. Sitting here in the office I could imagine so many things but hmmm, what do you think? - ECU learned bullshit because of the "now fixed" boost leak? - Boost overshooted and is beeing retarded? - Timing correction (logged about a month ago without timing corrections in the sports map but this was before FMIC, DCI, Forge DV install) - Leaking Forge DVs? or maybe laggy DV reaction? - another boost leak? had no time and not really dry roads this days for logging ;-/ EDIT: or maybe this is due to the restictive oem downpipes which are still installed ? |

If it's a cylinder that always makes corrections regardless of the map or octane then it's probably a plug, coil or injector on it's way out.

I have some questions about Cobb AP before I decide to buy one. First, if I buy a used Cobb AP and the owner never "unmarried" their unit, would it render the unit I bought useless? Does Cobb offer a wastegate fix for the wastegate rattle? And if I get my Cobb protuned and then go back to stock for a dealer visit, would the pro tune still be on there? Thanks for any responses!
