I bought a used Tech 1 two weeks ago, and today, with a newly acquired "Operator's Manual", I played a bit with this tester on my '90 ZR-1. Wow! The Tech 1 is a very useful and powerful tool. It reminds me of the Bosch KTS-300 tool (AKA The Hammer) I had in 1991 or so when I was driving a Porsche 911 Carrera 2. Like the Hammer, the Tech 1 doesn't just read fault codes. It allows you to test and even change lots of other things. I had fun playing with the IAC test changing the idle in increments of 25 rpm at a time. There's even an idle relearn program to reset idle to compensate for engine wear and tear. I was also pleased to find that there was a "Block Learn Reset" function to return all block learn cells to a nominal value of 128. I paid about $2600 to Porsche in 1991 for a new Hammer and only a bit over $200 for my used Tech 1 this month. All in all, though, both were well worth the price.
