Well... there we go!
Wait, why is it only peaking at 12.5 psi then?
Normal, my MT does too on Map 0 (stock). I'm telling you man, these MTs are calibrated differently lol
Wut. Even my 2020 hit 19 psi peak.
It depends on IATs, but yeah under 100 IAT, my car will read ecu_psi as 11-13. At IATs >120, it can get into 14-16 psi and runs lower timing. Stock map, tuned maps, whatever.
The 2020 requested load/torque is different than 21+, but roms 21+ are the same. As well as the feed forward (base WGDC) and PID tables.
Alrighty, got 2 logs in. Map 1, with the duty cycles you previously gave me. Hope I did it right this time?
can confirm, here's a log from over the winter. dme_bt targets are in the low teens and peaks in the ~13 psi range when iats are low. makes sense, if knock is unlikely, the dme will meet the requested torque with more timing and less boost to optimize fuel economy.
Gonna have to drop FF until throttle clears up. MTs typically end up near 15-25. Send me a PM with your next log at FF=25
For the future, I know some “tuning guides” state that the DME uses timing to meet requested torque when IAT’s are lower but that actually isn’t 100% true. In stock tune trim, the ignition maps are pretty aggressive and so is the IAT timing reduction. So when the IAT’s are cooler it basically uses way less IAT timing reduction. It’s not actually calculating more timing to meet the torque request, it’s just using less timing reduction.
