Traction Control won’t turn off

I’ve been having a problem where my TCS will not turn off when I push the button to turn it off for quite some time.

It has been happening both before and after my MWC Rear End swap. It started noticing it after my LS3 swap. I know the original shop that did the swap had a hard time tuning my car and I had to take it somewhere else to get it done.

My backing plates are brand new and I verified that they are properly connected and the harness properly seated so I know that’s not the problem.

I also checked the switch with a multimeter and I am getting continuity through the switch leads to ground so I know the switch is still good.

I noticed something in my tune for TCS and the values are completely zeroed out. I also notice my TCS engages a lot more aggressively than it did when I was stock. I read somewhere that this could be a contributing factor… but I don’t know the stock config for those values. Does anyone have any idea?

What are you looking at your tune with?
HP Tuners has a tune repository where you can find stock tunes.

I guess I won't assume it's a 4 channel 4th gen f body.
What kind of vehicle is it?

It's a 99 Z28 4 Channel system.

This is under Traction Control System TCS method retard vs RPM. I was told those values should be populated...
Edit: Checked the stock tune in the HP Tuner repository and they are populated. Should I re-populate mine? I am running an LS3 with a BTR Stage 2 CAM and a 3600 Stall.. ..not sure if this will cause it to detonate should TCS kick in?

That retards the timing so it loses power and works basically. Those numbers need to be there if the rest of the system is there and active.

Cool, I went ahead and added those numbers using the stock settings. TCS still won't turn off though. Is there anything else in the tune that can be preventing this?
