Nice. Wonder why the rest of them from that company don’t work.

Not sure, maybe installation error ?...I did call Dave several times through out the install, I at first, installed the thermo-coupler in the wrong location bc the directions (directions error which I told Dave about, so hope he changes it) said to put it in the coldest line after the chiller so I put in the line coming right out of the chiller, but then realized that, that wouldn't work bc that's what is reading the temp to switch from stock HX & chiller so it needed to be in the main return line going to or coming from the s/c, where it will read temp no matter if I was using the stock HX or chiller either way.
But instead of setting up this system to work automatically between the thermo-coupler & the digital controller to switch bypass valve, between stock HX & chiller, I just installed a manual switch to control the bypass valve.
There is a few different ways you can go with this kit so you have to find what works best for your use & make the necessary install adjustments.
So far I'm happy with the way I did it.

Hickstah Here,
I saw some things I liked and some didn't. What is the silver alumiumn foil lookin stuff?? Good things Armacell and or alflex on cold lines, 3 way control valve, cleaned all heat exchangers. Very good. Flexable conduit on control wiring. Change over control valve ??? Used your 134A ?? If so, extra gas added. System seems working good. Why others failed?? Numerous reasons. You have seemed to use the 90 degree street sweep 90's but the ones going into the cooler, so called are straight 90's. As you can see there is no room for street. Every closed 90's and or extra 45 fittings takes the equilivent of 10 feet of straight feet of piping, thus restrictions. This seems not to have too much affect on your instulation. I have seen other units and they were very flawed, espicially the 3 way control valve. And maybe an air seperator or extractor?? Pressure gauges supply and return thru the air cooler to see if exchanger is getting clauged and or pressure drop. All concerned would make a good system.

I used Armaflex insulation tape & Nashua aluminum tape over the insulation tape on all the hard pipe on the s/c lines & on the manifold at the back of s/c. And I used pipe insulation wrapped the lines going in & out of the chiller.

I just used the 90's that came in the kit.

I used 1234yf Freon (factory).

You did good and that my have an affect on why your install turned out better than other's installes. The 3 way valve and low voltage wiring came with the package?? Big difference between the cold and hot piping insulation. If you have one,, take a laser thermometer and take readings on both. Thickness makes a difference. Did the package come with, add, or did you install pressure guages and or air eliminator to the system?? I am sure the system seems to be doing what it intendnes to do. I wood have looked at added this one with the guages and seperator and has my stamp of approval as a chiller mechanic and 30 years HVAC, control mechanic. I am sure your happy. When mine is out of warranty , I will use similar system but add VFD applied and continue to condeme these inaffecent underrated contraptions. If you or any one else needs info I will find it. The cleaning of the H/X of the other components makes a huge difference.

Did the package come with, add, or did you install pressure guages and or air eliminator to the system?? No, but I did buy a vacuum & refill kit for radiators to refill the I/C system, so no air in the system.

I also put the thermo-coupler in the line after the coolant has gone through the s/c & pump (post s/c & pump), b4 it goes to either stock HX or chiller, so on the digital controller I can see that temp, & on the cars performance pages, I can see the I/C (pre s/c) temp & see the Delta, witch is 3* > 5* , I think is pretty good.
