Thank you so much for taking the time to reply. I'll check for exhaust leaks. I'll try to figure out if the knock sensor is wired in so knock control can be turned on. It's a plug-in ECU so I think it should be connected. CL lambda being off makes sense why the car doesn't want to adjust fueling much when it's lean. I'll try to figure out setting that up. I'll turn down the coilpack values too.

Hello, I have a 1996 Ver.4 WRX. It has the original EJ20k motor which ran well on the factory MAF set up but drives relatively poorly on speed-density. When switching to speed density, I also opted for ID1050x injectors, radium rails, 3-port boost controller, DW255 pump and an AEM wideband wired into the G4X. It made 247awhp after being pro-tuned on a hub dyno. Issues: -The idle dips below the target rpm values and recovers often when clutching in or coming to a stop. -Severe issue with top mount intercooler heat-soaking the IAT. If the car is idling in traffic or hot starts, it will begin to run more and more lean. The high IAT values persist even when moving with marginal improvement. I may try removing the intercooler to flush it out in case there is a layer of oil on the sensor. I'm confused why my wrx can't handle a top mount IAT location. -Car occasionally stumbles/hesitates hard when accelerating WOT. -Extremely rich cold start with weak idle. -Car also bucks on decel in gears 1st,2nd, and 3rd gear. I think its more to do with drivetrain slop than engine tuning but wondering if its possible to reduce through the tune. Guesses about cause: -Could the IACV be wired backwards? -Is the charge temp table set up correctly? -Main fuel / warm-up enrichment table look reasonable? I uploaded the tune I'm running along with some log files. https://drive.google.com/drive/folders/1Br4WCLON1kLUO2zlzIu-I_jo5MRV-YR9?usp=drive_link Thanks for the time, Rosh
