**MISC TAB EXPLAINED**
**Disclaimer: this is what i understand the features do. If you see a mistake, which i like to make a lot, just let me know and i'll edit the post. thanks!**
Knock Sensor:
A knock sensor detects knock in your cylinders. The factory one is all but worthless, but hey, if you have it you might as well use it.
VTEC:
Allows you to disable VTEC by unchecking this box. When VTEC is disabled, the car will always remain in the low cam setting. Very useful for determining optimum VTEC engagement point, or tuning low and high cams seperately.
VTEC<20 MPH:
A requirement for VTEC to activate is that the car must be moving in speeds greater than 20 MPH. Checking this box will allow VTEC to activate even when traveling below 20 MPH.
VTEC Coolant Check:
A requirement for VTEC to activate is that the car must have reached full operating temperature. Unchecking this box will allow VTEC to engage even when the coolant temperature are below normal operating temperatures.
PA Sensor:
The PA sensor is a "Pressure Air" sensor, or otherwise known as the Barometric Pressure sensor.
ELD:
ELD is the Electronic Load Detector.
O2 Heater Disable:
Checking this box will allow you to disable the heater circuit for your oxygen sensor. This will force your car into all-time open loop, and is also used when running a wideband o2 sensor that feeds a narrowband signal to your ECU or datalogging wideband a/f's through uberdata to prevent throwing a CEL for bad o2 heater circuit.
Remove Speed Limiter:
Some ECU's will have a factory speed limiter, that will not allow the car to travel faster than a certain speed. Checking this box will remove that limit.
Injector test disable:
I honestly have no fucking clue. Someone edit this post with the right description of this function so i don't look like an incompetent dumbass
VTP:
VTEC pressure Switch. Another requirement for VTEC to engage is that there is sufficient oil pressure. This option allows you to disable it, and activate VTEC regardless.
Closed Loop Disable:
Allows you to run your car in constant open loop. I personally prefer to run in open loop when tuning so you don't get that gay switchover from closed -> open loop.
Injector test circuitry is some extra crap on USDM ECU's that isn't on JDM ECU's; the injector test disable allows you to run Uberdata on JDM ECU's without getting a CEL.
O2 heater disable prevents the car from slipping into closed loop due to an oxygen sensor code; it doesn't prevent it getting into closed loop via throttle position
