How to set TPS soft closed point correctly?
I warmed the motor up, unplugged the TPS, started it, revved it over 3000 rpm 4 or 5 times, turned it off, plugged the tps back in and restarted it.. I assumed this sets the TPS soft closed point for the ECU.
It wont go lean when closed throttle and coasting, i can turn the TPS down to about .43 volts and it will switch to 'closed throttle' in consult and it will cut fuel when coasting, but it leans out strangely at low throttle sometimes, not if its in the voltage range it should be. (.45-.550) i believe
Im going to leave the battery cable off for a few hours and see if it resets.

Listen to this guy. I followed his tip when troubleshooting my own TPS issue and this fixed it.thesandman4444 wrote:to reset the tps idle unplug with the ignition on, switch off then back on and plug it back in. Is it an oem tps? The parts store replacements have slop in them and it messes with the low throttle and tps closed point.

That's weird. How high is your idle?

It was around 900, and warmed up. i dont have an IACV, maybe that messes with it. I tried it quite a few times, and different ways while watching in consult.
I was getting detonation at 13degrees and 8psi, after setting the soft point i am now at 14 and 17 degrees, no knocking Feels like real KA now. Too bad my turbo is taking a dump now lol
Not to mention im back to 25+mpg rather than 20
