So I had someone else build me my MS2v3.0 for my M42 just due to not having time to do it myself and I've been having a issue with getting the icv to work on it for a while.
It originally did not have the PWM ICV mod- kit which is just a TIP120 transistor, and a diode. I bought the kit and followed DIYAutotune's instructions on how to install it.
I removed Q4, Q20, D8, and R39 from the existing setup then jumped R39, and installed the TIP120 as followed into the Q4 spot.
Here's pictures of my board after I modified it.
The output for the ICV is Fidle, and I set the valve frequency as close to 255hz which I believe is correct. Here's a picture of my Idle control settings in Tunerstudio.
I also put the diode in the pins for the connector of the idle control valve as followed:
I'm still not getting any response from the valve, I can see that I'm getting 12v from the connector but no matter what I do I can not change the position the valve is in so it's basically like having no icv and it sucks waiting for the car to warm up. Is it possible I damaged the transistor by soldering it too hot, and or the MS board?
Any help would be awesome since I really want to get this thing working so I can make my car more daily drivable than it is right now. :(
