Hi all, something strange happens after the engine fully warms up. The first pulls feel strong, but later the behavior changes and response drops a bit. Is this normal, or could it be masking a tuning issue?
Hi, that’s a really good observation. I’ve noticed that once everything is fully heat-soaked, ECUs often start protecting the engine more aggressively. Timing changes, fueling shifts, and suddenly the car feels different. When I was tracking my car's performance, I realized I needed to separate warm-up behavior from true operating behavior. The modules Dynotest https://dynotestpro.com/ helped because they allow repeatable testing at specific temperatures and load points. That made it clear whether the change was thermal management or a real tuning flaw. Warm-up runs can be misleading if you rely on them too much.
