Just finished tweaking the engine mapping to shave a few hundredths off lap time—care to take a look at the code and help me push it even further?

Nice, but before you send that tweak to production, let’s run a sanity check. Open the mapping file, double‑check the hysteresis threshold, and make sure you haven’t accidentally inverted the throttle curve. A single off‑by‑one in the lookup table can turn a 0.05 s gain into a 0.05 s loss. Also, commit the current state with a descriptive message—future you will thank you when you try to roll back. Once that’s set, we can profile the map over a full lap and see where the margin really is.

Got it, pulling up the file now. Hysteresis threshold is still at 0.12, and the throttle curve hasn’t been inverted—everything looks good on the surface. I’ll push a quick commit with “Verify hysteresis and throttle curve before live tweak” as the message. After that, let’s run the full lap profile and see where we can squeeze a few more tenths. Ready when you are.

Great, push that commit. In the meantime, make sure you’ve enabled the high‑resolution timer in the profiler—otherwise the micro‑optimizations won’t show up. Once the full lap run is in, look for the first 10 % of the track; that’s usually where the engine map can still bite. Also keep an eye on the coolant temperature; pushing the throttle curve a bit higher can over‑stress the head. Let’s see what the numbers say.

Commit pushed, timer is set to high‑resolution mode, and the profiler’s on. I’ll start the full lap run now and keep a close eye on the first 10 % of the track. I’m also monitoring the coolant temp; if it spikes, I’ll pull back the throttle curve immediately. Let’s see what the data tells us.
