Noob to the Cobb and Subbi world. Former RX7 - RX8 Tech Hi all those are the add-on's on my vehicle. I performed a compression test with 0 throttle and all presures were in the 128 with the highest in 130. i might have the wrong map flashed or i dont know but Groot is not happy. it ran well for a while and now it just stated sputtering and hesitating. Your help by looking at this log would be greatly appreciated and suggestions are also welcome. Thank you in advance. https://drive.google.com/file/d/1DFu...ew?usp=sharing

only mods: AEM Cold air intake rear muffler delete Hello again Curently I'm runing on Cobb Stage 1, 91, v.4.00, normal wastegate. After 500km, DAM droped to 0.688 and also during hard accelerating I falt jerk, so I made 3rd gear pull log, and I've notice the throttle drop when boost is reaching 18.7 PSI. Should I try High Wastegate? https://datazap.me/u/lutek34/log-163...0&data=6-19-21 |

Dude you are in the wrong forum. EJ's need a wideband. You are running a external gate on a OTS map? WTF!? RIP ringlands Quote:
You should be logging wastegate and ignition. I think the low wastegate map would help avoid throttle closure or you should get a protune. Last edited by tegxsi; 11-12-2021 at 03:33 PM. |

boost curve is like oscillating like a roller coaster... I think the low wastegate map might be better for cold weather. Other than that it looks alright. Proper tune with 3-port EBCS will offer the best boost control. |

reveiw please
I am by no means a pro tuner but I'm currently tuning my own car using ATR. Learning as I go. Need some constructive criticism. Boost is turned down a bit while I play with the tune.

Here’s another one

It’s definitely at e30 mathematically. Probably actually a couple percent more. 15.9 gallon tank was at about 1/8 left added 4.9 gallons of e85 and filling the rest with 93 octane. There is a possibility that the gas station has a lower ethanol content being close to winter as well. That variable is currently unknown, looking at getting a test kit. I do not have a flex fuel sensor. Yet. I did pull a half a degree of timing, seemed to clean up that FKL. DAM hasn’t dropped. Last virtual dyno I ran was 350 hp 362 lbft. Not entirely sure how to post that graph here. |

Usually should be able to run a few more degrees and ramp up timing up top. Maybe try running flat 11.5-11.6 AFR instead of tapering. |

Hi there,
New here and very new to mods but I'm pretty sure there something really wrong. On idle my AF learning 1 is -26. any help would be much appreciated. Below is log and mods. I wasn't sure if I should post here or start new thread. Log is at idle with a bit of throttle play. https://datazap.me/u/mike1980/log-16...?log=0&data=28 - 2017 WRX Sport Tech -Cobb Stage 1 + Big SF Power Package -Boomba recirculating bypass valve -Cobb acess port - 6MT - Fuel 94 petro Canada - Tune OTS Stage1+BigSF 93*v400 - Gear used is N at idle and bit of throttle play Thanks Mike |

The total fuel trim = AF Learn1 + AF Correction1. I'm seeing about negative 12-16% correction. On these cars +/-10% is acceptable for AF learn. Clean the MAF sensor. Make sure the sensor seated properly and the electrical connector is secure and free of corrosion. I suggest you pack the connectors on the extension harness with a little dielectric grease to protect it from moisture. Cobb intakes can be a little touchy with filter placement. Make sure the filter is straight and only insert the filter flange about 3/4-1" inch into the pipe. Last edited by tegxsi; 12-28-2021 at 06:24 PM. |

I was thinking of buying a smoke test machine to check for intake leaks but they are like $300 so don't want to waste the money till I really look around under hood. The P0300 is definitely a concern I would think? |

Go over all the clamps and hoses again and see what happens... P0300 random misfires can happen at really cold temperatures. Carbon build up on the valves might play a role in this too. It should smooth out once you get some heat into the engine. |

Similar issue with your idle logs. AF correction is on the negative 10-14%. That's what a custom tune will fix but it's running fine. Last edited by tegxsi; 12-29-2021 at 08:48 PM. |

intercooler and ebcs would be the best especially the intercooler as the stock one isnt that great in the hot weather and when turning up the boost.
The ebcs you will need to install on a etune/dyno tune as no OTS map that i am aware of supports that unless you get one through a tuner as some offer their own ots maps (Ron watson i believe specifies that a regular etune is needed as it requires a lot more fiddling with the tune to get the boost right as the ebcs is more precise) |

Also I fixed my low STFT. I took tegxsi advice from above and put some dielectric grease on both ends of the COBB electrical wire harness extension going to the MAF sensor. re-flashed the OTS map drove the car around a bit and my numbers are real good like better then I have ever seen them -7 to +7 or so) so big thanks to tegxsi fort that zi still want to do a intake smoke test for peace of mind at some point when I get a smoke tester to be sure I have no leaks before tune. |

I know in Britain they use just the RON measurement so their roughly 97 octane is actually equivalent to our 91 octane. |
