TCC pwm
its an on/off pulse not a sine or triangle or anything weird. If you put 99% in the software I assume it means 99/100 of the time it is found to be "ON". which is pretty much just on all the time, like a switch.
Thats how most people say they program the TCC. However I still prefer some less % minimum at least to reduce drivetrain shock at low loads. It is a tunable feature. So again i assume 75% is 75/100 of the time, pulse is "ON".

That's the duty cycle not the frequency. I've done some deep reading and I *think* it's 32Hz
I want to use the tcc solenoid control as a trigger to a solid state relay. Essientially use the stock pcm as a nitrous controller.
Since pcm can only do lockup in 2nd gear and on, it would probably be for a 2nd stage. I wish it could lockup in 1st.

I was looking at it on mobile and totally missed your reply! Thanks!
Is there any vehichle with a 4l60e that has the availability to lockup in 1st? Would be worth the segment swap if so...i strongly doubt it tho

The unit is simply "on" for those pulse periods approaching 99/100 of the time, whether it is 1 time per second or 32 times per second.
Do you mean you wish to cycle a solenoid with TCC pwm output? It goes against the computer's thinking of 'locking up' when there is a reduced throttle position. In my HPtuners the release feature doesn't work at all. Furthermore the behavior of 0% minimum release is intermittent. I would call it extremely risky to let this finiky output play with nitrous. Not my gen3 411 ECU anyways. IMO this is a bunch of unnecessary bs and the wrong way to do nitrous. It should be activated through a combination map and tps, through a progressive controller. You want to play with electronics, write the digital arduino code to control the solenoids from your own board and design the solenoid driver as an external upgradable. It doesn't take much hardware, you can buy almost any IC you need now for pennies.
I am not going to say anything negative about trying and learning but I can't argue about trying to use Arduino. I know that someone is now using this as a boost control to pulse a solenoid.
