a by-product of that is boost drops...

(charts aren't scaled the same but you can see the tps drop and the boost dip)

Tephra, are you saying that we could be losing power from this since the asc tries to control our torque and pulls torque if we go over the limits? i've tried adjusting my torque limit tables but it still comes on no matter what the values on the torque limit tables are, along with airflow. Even if i hold the ASC button down for 5 seconds and disable everything, it still shows up at high loads. should i be worried?
a) no

b) no, some people are contending that ASC restricts power, I am asking for logs of this

ASC WILL send a torque modification request when it detects wheel spin, OFF/OFF mode should block this behaviour

Is that logged TPS or APP?

might be coincidental but that dip in TPS was right when i was going to break 30psi. i have a bit of catching up to do, just got in the office. i'll get the log up here in a little bit.

i wasn't logging WGDC error correction to see if that came into play, i'll get some new logs tonight. unfortunately i just have this 1 3rd gear pull (the other pulls the error already kicked asc off)
here is tps & boost scaled correctly. it may just be coincidental that the tps drops a few points after i break 30 and tripping the warning screen.



after looking at this a bit, it looks like it dips every time i break 30

Can I ask what your equation for logging boost is? The part I'm interested is the "-14.5" part. I curious what you are subtracting for Atmospheric Pressure.

that's interesting that your TPS does that when you go wot, fluctuate. Mine stays solid at 96 the whole time i'm wot.

Same here, but my max boost is 28 psi... not close to 30 psi...

Might be some salt to this if you approach close to 30 psi your TPS fluctuates...
