I installed the controller on my 16 HC. No issues. Car was more consistent at the track, I think, but only had one day of runs I made with it because the season ended. Will try track mode setting next year. I used street susp since that's what I have been using and this was bracket racing, so I didn't have a chance to experiment with it.

Quick update. I think it is easily worth the money. The street manners and balance of the car a very different.

I went to the drag strip on Monday for some non scientific A/B testing. I had carpet out and secured the controller with two screws to make change overs as quick as possible. First two runs were in the same lane, switched lanes for the final two. First time at track with this car. Foot brake launches at 1500RPM, no roll on, just straight to floorboard. Dead hooked. I’m sure I could have done better, but I need more seat time in this car and wanted to be as consistent as possible for this test.

I did six total passes. The first two were just to get comfortable with the car.

Four test passes
1 - Stock controller 1.573 60’
2 - Change to DS controller and hot lap 1.521 60’
3 - Two hour cool down (DA dropped from 700’s to 120’s) DS controller 1.487 60’
4 - Change to stock controller and hot lap 1.536 60’

Hey, nice write up. My question for you is did you run the car in street suspension usually prior to getting the controller?

So for all the runs you ran in track, right? Did you try the controller with the car in street for suspension?

That's an excellent 60' with running a 20" tire and the ET street SS.

What kind of shop sells/installs this type of device ???

Easiest install in the world. I installed mine at the track one day in like 10 minutes. HHP sells them, as do others.
