I tried to get a datalog today but i'm not sure what happened. When i got home the datalog1.csv file was 0kb and when i tried to transfer it to the laptop it said failed to copy from AccessPort.
I think I read it might have to do with the gauges im running interfering with logging? I use 6 (boost, boost delta, boost req, AFR, CAT, WGDC) so it's a lot. Going to try again but changing to 1 gauge and try a few times. Anyone seen this symptom before?

First datalog attempt. Things look ok pro/enthusiast thoughts?
I think I figured it out and got it this time. From reading the datalogging thread I think the tune is doing ok and timing is ok. I see a little correction in the beginning but what im worried about is after chagning to 4th gear idk there's a lot of corrections but is that normal there was i supposed to shift and keep WOT cause i just kinda let off after shifting? Through the middle looks at 0. Req boost vs act boost i think is ok :shrug: TPS Act % 81% across I think. Charge Air Temps ok too i think.
Let me know if things look solid or if there is any other parameters I missed in the log that might help. This will probably nudge me into protune territory to dial it in if it is. Here is a link to the datazap I created: http://datazap.me/u/e92enthusiast1/stg-2-fmic-st-sport Quote:

The first couple corrections at the start of the pull aren't really of concern but the corrections after the shift aren't pretty. During and immediately post shift are two of the most common times to spot corrections because of the sudden drop and jump in load. I see you're in AZ, I assume you're running 91ACN fuel. The "sport" map is designed for use with regular 91 and looks to be a little too much for ACN fuel. Aside from the corrections it looks pretty good. |

Thanks for the follow up. That is a bummer really about the gas. I know we have an e85 station so I will try and raise the octane a little. I'm just not sure how often I'm gonna be filling up at that station. Might just try the non sport map.
I have some room in the tank. Is it not ideal to mix the e85 after? in other words should I wait til its almost empty and do e85 the first few gallons? Quote:

So after the first run when we noticed major corrections on shift I tried a couple runs after mixing in a few gallons of e85 and it looks better I think. Not sure if no corrections at all is a thing but before it was like -6 across all cylinders now its just -3 across 3 cylinders. What should I be looking for? 0 across all cylinders? Or is this good enough.
Stg 2 FMIC+ ST Sport 91 ACN w/ timing corrections a lot Stg 2 FMIC+ ST Sport 91ACN + e85 corrections minimal I'll also do another run tomorrow and throw it up. After the e85 has had a chance to mix in the tank real good. Here's the latest run after having the e85 mix in the tank for about 24 hours and I think this one looks the best as far as corrections goes. Even through shifting. Stg 2 FMIC+ ST Sport 91ACN + e85 even less corrections than before And just as a little anecdote to these engines and tunes right before this last log I had an ///m3 on the highway that was just amazed, he was asking all about what i had. Of course, i told him with the biggest shit eating grin of my life. In straight pulls I was giving him a run and he was impressed. Quote:

Hey guys, loving my Cobb tune so far except one issue that seems to surface infrequently but is severely debilitating and somewhat dangerous (ie. overtaking and totally abrput power cutoff - as if someone yanked the car back). The car ran flawlessly before the tune.
P0238 code (TurboCharger Boost Sensor Circuit High Voltage). In addition, it threw a misfire code (P3100) and a 2ABC (TMap fault?) and a 2AAF (a quick search says to ignore this one as it is not significant). It happens during WOT, and only about 10% of the time if not less. The symptoms are a sudden cut-off of power and the car abruptly yanks as if someone slammed the brakes. Then it goes into Limp Mode (reduced power). Restarting the car puts it back into normal mode and it can be driven WOT for a while before re-triggering. There are no other drivetrain mods to the car; stock DPs, stock FMIC. Any help?? |

You should create a separate thread imo, it will get more views than on this one since the title isn't anything related to your issue.
On it include maintenance history, plugs/coils age. What map you flashed. Whether or not uninstalling the COBB gets rid of the issue. What about just flashing Stg 0. All this would be helpful. Quote:

Fair enough. When I searched, it kept hitting results in this thread but obviously I wasn't going to sift through 390pgs, lol. So I thought I it would be better to post here than create a thread for the same potential issues.
But I will do so now! |

If you have easy and reliable access to E85 then there is a lot of power left on the table by running the OTS maps. |

Thanks for all your tips/opinions Allen.
e85 accessibility is pretty good around here. It's not everywhere but im never more than 25 miles from a spot. I definitely have some things to learn. I will do more logging with STFT and go from there. I see COBB has some e30 maps on their site. I might move up to that after a bit. My goal is to eventually be knowledgeable enough to use Accesstuner and customize something to my setup/environment. Quote:

Personally, I highly recommend becoming familiar with ATR if you're comfortable doing so. A really good way to get started is to read the "Help" file included with you ATR download, it covers the basics really well. |

Cool, thx for the heads up. I got a COBB FMIC, VRSF Dp's, DCI's and a metal CP. I guess im missing the cat back exhaust though. That's coming soon!
I will definitely read up on ATR. Thx guys! Quote:

You have to manually transfer over the appropriate files to the Cobb while it is hooked up to your computer. Prior to that you have to download the maps off Cobb's website, specific for your ECU.

New with Cobb AP , just replaced my ESS stage tune with stage 2+ from Cobb, the FMIC LT. I felt the improvment for sure. Shortly after I changed for the OTS E30 map , used calculator to try find amounts of 93 plus E85 to fill.
Went for a spinn and oh boy , beast mode.... Now , for the logging part required while running these E30 maps , I logged some during driving , not sure what info I grabbed but I got some files. I was specially looking for timing corrections , on all cylinders while driving , highest negative value I got was on cyl 1 , -3,4 Is that in the safesone or do I need to do something ? Boost maxed out at 1300mBar Need to beef up my subframe ....
