immy21 Posted July 2, 2019 Report Share Posted July 2, 2019 Does anybody have recommended control settings for Bosch motorsports 60mm E-TB part number 0280750151?https://www.bosch-motorsport.com/content/downloads/Raceparts/Resources/pdf/Data sheet_68749835_Electronic_Throttle_Body.pdf Quote Link to comment Share on other sites More sharing options...
AEWON Posted July 3, 2019 Report Share Posted July 3, 2019 I’m after the same info, i’ve also got there universal pedal too Quote Link to comment Share on other sites More sharing options...
immy21 Posted July 30, 2019 Author Report Share Posted July 30, 2019 Initially the TB calibration would error out, found the fix via forum search, had to switch DC + and - wires This is what I have managed, main focus was to keep oscillation at bay, I don't think this is good enough. Any obvious PID tuning errors from experienced members? I'l try again in the next couple of days.

barge Posted July 30, 2019 Report Share Posted July 30, 2019 I'm not sure if the Link software supports zero'ing out gains but you'd typically tune a PID loop in order. Tune the P gain until it overshoots, then back it off a touch. Then tune the I gain to handle that last 10% of motion to get it to follow nice. Then play with the D gain and tweak it. Based on those charts I'd say you need more P gain. You can do all this testing with the motor off so you're not rev'ing to the moon or crashing into things (mentioning it because you say you have a drive home log).

immy21 Posted July 30, 2019 Author Report Share Posted July 30, 2019 Thanks for the reply, I'm guessing there is no feed forward/base duty cycle as Zero'ing the gains results in no throttle movement. Initial setup and the short log is with the engine off. Quote Link to comment Share on other sites More sharing options...
cj Posted July 30, 2019 Report Share Posted July 30, 2019 Heres one I prepared earlier on the ethrottle PID tuning process Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 31, 2019 Report Share Posted July 31, 2019 Your throttle control doesnt look bad to me. You might find a small improvement but I dont see much to worry about in your log. A little less P & D and a little more I would probably work better, try p=7, I=0.1 & D=45. Quote Link to comment Share on other sites More sharing options...
