Today I disabled ETC (electronic throttle control) entirely, unfortunately this is not map switchable and requires reflashing the ecu. For track days ETC off is ideal as the ECU never interferes with the throttle but since the ecu cannot control the throttle itself, the downsides are numerous:
- no throttle cut at rev limiter (safety before fuel cut)
- no SRM
- no cruise control
- no throttle control for VDC, in theory with VDC on it would still control the brakes but not the throttle which could lead to some nasty conditions
There is a huge difference in throttle response, and I get full TPS voltage with one exception. it seems that below 2000 RPM the throttles don't like to be fully open regardless of pedal position, once you get past 2k you get full TPS voltage. So it would seem that my throttle issues are solved with ETC off, and that means theres hope to eliminate the weird throttle issues by adjusting the Throttle maps in uprev.
