I believe that the ITAC did a great job on this rule!
It will allow for a lot of new cars to join the IT ranks.
Lets remember guys, they don't make Pintos and Rabbits anymore. The rules written when these were the main cars in IT just don't address the needs of the more modern car with it's more sophisticated electronics.
There are many less expensive ways to correct the mixture and timing on many current cars that were not allowed by the old rules, or made prohibitively expensive by the old rules.
Sounds to me like the "Haves" just don't want us poor riffraff with our junk yard conversions up there racing with their $40,000 toys. Too bad, more competitive cars make for more fun at the track.
I for one will still run my stock ECU with a couple resistors in the temp circuits. Good enough for me.
