FA20 COBB Logs - Post Yours Here!
Hello all,
I wanted to keep this to just the FA20 turbo motor in general, but I like looking at logs and learning about what is good vs. bad from a log standpoint in regards to tuning at different levels. I did not see any threads started for general data log review for the FA20 so I figured I'd start one. From simpleJ: Quote:

Holy rich.
Please please please please log command fueling guys. We have no idea exactly how forked your engine/intake/tune is in open loop without logging this parameter |

Edit: The pull may have been slightly uphill, in 4th gear, and yeah trunk full of air ride. I believe 4th puts more load on the engine, I now see that everyone wants 3rd gear. Last edited by gn4rwhals; 02-24-2017 at 02:07 PM. |

I really like this datazap format. Agree that you are a bit rich, but like you said, this is an OTS map, and not a custom tune.
I'd really like to see some more of these from different tuners. |

Datazap is life man, I started the engine tuning discussion on the MQB VW platform a few years back and got everyone hooked.

Knock Learning Issue
Starting off from a stop to do a pull I had a large knock learning of 9.84 caused by what looks like the feedback knock of 1.41. I have no idea why this would happen should timing be lowered to correct or is this some other issue. Thanks

Gotta imagine driving around with unsupported EGR deletes has something to do with that.
You are super lean at WOT for an OTS map, something is very, very wrong I would think. OP is running several full points lower AFR than you on like the same map. Wait until Simple and ericdet can see this but, but Id say stop WOT immediately. Last edited by GlarryHoodDIT; 03-01-2017 at 01:47 AM. |

You're running lean. Maybe you're underboosting too, idk, I can't tell because there's no target boost or intake temp logged. That's too many lines of data to take the time to sift through. 3rd gear 2000 to as close to redline is safe please on a flat road and just flatten the loud pedal. Please log command fueling and target boost at minimum here if you're going to post a log. I'll poke over the rest of what you have when I have a moment at work Last edited by simpleJ; 03-01-2017 at 06:40 AM. |

Never bothered to look at commanded fueling, why do you believe that is better than looking at the output, the AFR? DataZap is awesome, got a bunch all organized there, here's some highlights: Here's some beating on it on a stage 1 93 ots (15 wrx, 93, MT, AP only, 3-4-3) and the car knocking a little: http://datazap.me/u/uofime/transient...96-353-458-415 Here's an OTS stage 2 93(15 wrx, 93, MT, AP + catted J, 3-4) also knocking a little http://datazap.me/u/uofime/ots-s2-11...&zoom=762-2125 same time, trying to roll into it a little more see if that helped knock: http://datazap.me/u/uofime/ots-s2-11...zoom=2192-2779 Protuned, the weather gained 40 degrees and I replaced a clutch that may have been slipping during tuning( 15wrx, 93, MT, AP cattedJ tgvd egrd EBCS, 3rd gear) Having a little bit of a boost control issue, overboosting low and under high getting a little knock http://datazap.me/u/uofime/post-clut...18-19&solo=3-6 Map updated for boost control ( 15wrx, 93, MT, AP cattedJ tgvd egrd EBCS, 3rd gear) no more overboost, still really light knock, could be crappy winterblend gas on a warm day, keeping an eye on it.

The only reason I like target boost is that it shows you the boost curve and then along with TD boost error you can extapolate what the car is actually doing. I believe target boost reflects comp tables as well.
Command fuel final reflects target fueling the ecu wants at any given time. it gives context to an AFR value. If your car is running 11.6 under boost maybe it is lean, or maybe that's what the ecu wants. I can't tell that just from looking at the afr |

http://datazap.me/u/chrisy783/highwa...og=0&data=5-20 Just a simple cruise around highway and city streets. Just wanted to log normal driving to see if everything is ok. I got a revision shortly after this and have not logged since. I will probably do it this weekend with some pulls and share with you guys. |

2016 WRX - TP Tune
Here's my log. I'm on a 6th revision of a TP tune with just a grimmspeed EBCS and an ETS cat back. I'm pretty new to all of this so I'm not sure how to interpret the data. Can anyone provide feedback on how the log looks? Thanks!

for the last time.
LOG YOUR COMMAND FUELING. Map or command fuel final. better yet both. If not.... We cannot tell you how or unsafe your map is without this value. We cannot tell you if you are running lean or rich as it is relative to your map. We cannot tell you if your map is lean or rich. We cannot tell you if you have a leak. We cannot tell you if your intake is causing problems. We cannot tell you if your maf might be dirty. We cannot tell you if your timing is OOC because of your intake. Help us help you. at minimum also log... -ignition timing -af learning 1 -calc load -maf g/s -td boost error -target boost -intake temp -fine knock lrn -feedback knock |

I logged only what the tuner asked. Is it concerning that he's not looking at command fueling? or is that only necessary for others who did not create the map?

no- he knows what he set the value to in his maps. We don't have your tune so we cannot possibly see his fueling strategies which is why need it

Knock yourselves out.
Box stock 2015 WRX with a mediocre Cobb 91 OTS tune using 93 fuel. The first little bit of the graph wasn't full throttle until 2650RPM, so don't let that trip you up. Outside temp was ~20*F when logged. http://www.datazap.me/u/cgumina/3rd-...4-6-8-10-15-17 No knock learn, DAM is always at 1, only get the occasional BS -1.41 feedback knock from the AC kicking on. Car has been dead nuts reliable on this tune. I plan on putting the 93 octane flash in it once the weather warms up, winter fuel sucks. Last edited by CGumina; 03-06-2017 at 09:31 AM. |

Car is underboosting and running pretty rich.
Boost leak? Try the hwg tune? |
