So i finally got an OBDII device that lets me view sensor data in realtime. However i've noticed that no matter what i do the throttle position never goes over 75%. This occurs in power mode and normal. From a stand still, brake torqued take off, 20mph roll-on, etc. Is this normal for a GS300 or do i have another issue?

I've heard of this being normal. You're never going to get 100%.

On our car, we got a TPS that shows throttle angle and we got a "Throttle switch (TS)" that shows Wide Open Throttle (WOT). If you want to check if the TS has a problem, check the sensor, when the switch is "ON" it's at WOT, off its vice versa. You would need some T-pins and a DMM to do this.

Well that sucks.... so i guess fiddling with the throttle motor is a good way to get myself stranded....

..i never really noticed these things. im not much of a speed racer. i was just bout to say cant expect much from a 300 motor vs 400 and 430.

i with him, i don't think you'll see 100% throttle, but i don't know is 75% is high enough. the link to the manual is around here somewhere. in the manual, it will give you the initial blade angle setting which is around 14.7-16.3% i think and it'll give you the resistance range the motor should fall in. they're expensive, like $260 i believe, so i would diagnose it before buying one cause it could be a cheaper sensor like the tps.
