Title: excessive blowoff at part throttle??? Post by: tadope on April 03, 2022, 11:56:49 AM So I noticed at a track day (hpde) that during part throttle portions my DV would constantly be poofing off. This is where I was accelerating, but not needing full throttle.
It's extremely obnoxious and very not "smooth". The DV would sometimes vent five times around one corner. Is there a specific table I can look into editing to help with this type of thing? engine runs great outside of that. And it occurs regardless of how much boost i'm running. I've tried everywhere between 14 and 20lbs Setup: 2001 audi tt amu engine. stock turbo/injectors fmic I/E decat 4bar BAM wb conversion ecu Title: Re: excessive blowoff at part throttle???

Sorry I don't have any logs and the car is not drivable at the moment. All I have is the bin and xdf file. attached here... |
