220 duration requires computer programming
220 duration requires computer programming For A4 cars, Comp cams says their 216/220 duration cam requires computer modifications, however their 212/218 duration cam does not.
What needs computer tuning because of the higher duration? Idle rpm only, or other things as well?
Thanks.

the things you mentioned and also to get the most power out of the cam. But the 216/220 is small enough that you could get away without it. Do you have an aftermarket converter for your car? At least have one put in before a cam swap.
Regardless of any aftermarket cam you put in, you will need to tune it. Granted, you will have to make less/smaller changes with a smaller cam, you still need to make them. The computer is programmed to know only about the stock cam, nothing else.

My thunder racing 220/220 .551 .551 on a 114 needed tuning. Not much bigger than the one your describing? It would send a random multiple misfire code for no apparent reason from time to time and would stall at traffic lights if it sat still long enough. You would've thought it was a much bigger cam the way it behaved. All that with a Pro Torque 2800 stall. Much nicer after I had it tuned.
