It was two things, heat and incorrect calibration, that killed the 72.
I had one of the first ones as a test bed. When I first put it on it failsafed like a SOB.
I tuned on it for days and finally got it 100 percent. Then temperatures changed and it all went to pot.
I created a value file that I offered to other tuners and it was only happy on 07-10 cars. 11+ was going to take additional tuning development.
Although it had factory style Delrin gears, something in it was swelling and creating more friction due to heat and causing enough of a voltage difference that it took the easy way out and failsafed.
Mine worked fine otherwise but I wouldn't sell it to a general consumer.

I used to actually keep my 65 in my trunk when I had the twin 72. I got stranded with a wrench light once and that was the last time I left the house without my twin 65... A few years back, I made it all the way to Ocean City Maryland from the Philly area and drove around there for a day before it wrench lighted me. I thought we had it all worked out and couldn’t have been happier... that is until it pooped the bed on me on coastal highway... LOL
It made no sense, no rhyme or reason why... luckily I had the twin 65 with me in the trunk, 15 minutes and I was back on the road with no issues... other than not nearly as much fun...
